• SEO/Google: How should I handle multiple countries and domains?

  - by Valorized

  Hello. I'm the webmaster of an online shop based in Austria (Europe). Therefore we registered "example.at". We also own different other domain names like "example-shop.com" and "example.info". Currently all those domains are redirected (301) to the .at one. Still available is: "example.net" and "example.org" (and .ws/.cc), unfortunately not available: .de/.eu The .com is currently owned by one of our partners, the contract ends in 2012 but until then we have no chance to get this one. Recently I read more about geo-targeting and I noticed ONE big deal. The tld ".at" is hardly recognised in Germany (google.de) whereas it is excellently listed in Austria (google.at). As a result of the .at I cannot set the target location manually (or to unlisted). More info: https://www.google.com/support/webmasters/bin/answer.py?answer=62399&hl=en This is a big problem. I looked at Google Analytics and - although Germany is 10x as big as Austria - there are more visits from Austria. So, how should I config the domain in order to get the best results in both, Germany and Austria? I thought of some solutions: First I could stop redirecting the .info. Then there would be a duplicate of the .at one. Moreover, in Webmastertools, I could set the target location of the .info to Germany. As the .at still targets Austria, both would be targeted - however I don't now if google punishes one of them because of the duplicate content? Same as 1. but with .net or .org (I think .info is not a "nice" domain and moreover I think search engines prefer .com, .net or .org to .info). Same as 1. (or 2.) but with a rel="canonical" on the new one (pointing to the .at). Con: I don't think this will improve the situation, because it still tells google that the .at one is more important, like: "if .info points to .at, the target may still be Austria". rel="canonical" on the .at pointing to the new (.info or .net or .org). However I fear that this will have a negative impact on the listing on google.at because: "Hey, the well-known .at is not important anymore, so let's focus on the .info which is not well-known." - Therefore: bad position in search results. Redirect .at to the new (.info or .net or .org) with a 301-Redirect. Con: Might be worse than 4, we might loose Page-Rank (or "the value of the page", because google says that page rank is not important anymore). Moreover this might be even more confusing for the customers. In 3. or 4. customers don't get redirected, they do not see the canonical-meta-tag. So, dear experts, please tell me what the best option would be! Thank you very much for your advice in advance and please excuse the long question. I really appreciate this network! Please note: It's exactly the same content AND language. In Austria we speak German.

• ViewPager cycle between views?

  - by Erdem Azakli

  I want my ViewPager implementation to cycle between views instead of stopping at the last view. For example, if I have 3 views to display via a ViewPager, it should return back to the first View after the third View on fling instead of stopping at that third view. I want it to return to the first page/view when the user flings forward on the last page Thanks, Mypageradapter; package com.example.pictures; import android.content.Context; import android.media.AudioManager; import android.os.Parcelable; import android.support.v4.view.PagerAdapter; import android.support.v4.view.ViewPager; import android.view.LayoutInflater; import android.view.View; public class MyPagerAdapter extends PagerAdapter{ SoundManager snd; int sound1,sound2,sound3; boolean loaded = false; public int getCount() { return 6; } public Object instantiateItem(View collection, int position) { View view=null; LayoutInflater inflater = (LayoutInflater) collection.getContext() .getSystemService(Context.LAYOUT_INFLATER_SERVICE); this.setVolumeControlStream(AudioManager.STREAM_MUSIC); int resId = 0; switch (position) { case 0: resId = R.layout.picture1; view = inflater.inflate(resId, null); break; case 1: resId = R.layout.picture2; view = inflater.inflate(resId, null); break; case 2: resId = R.layout.picture3; view = inflater.inflate(resId, null); break; case 3: resId = R.layout.picture4; view = inflater.inflate(resId, null); break; case 4: resId = R.layout.picture5; view = inflater.inflate(resId, null); break; case 5: resId = R.layout.picture6; view = inflater.inflate(resId, null); break; } ((ViewPager) collection).addView(view, 0); return view; } @SuppressWarnings("unused") private Context getApplicationContext() { // TODO Auto-generated method stub return null; } private void setVolumeControlStream(int streamMusic) { // TODO Auto-generated method stub } @SuppressWarnings("unused") private Context getBaseContext() { // TODO Auto-generated method stub return null; } @SuppressWarnings("unused") private PagerAdapter findViewById(int myfivepanelpager) { // TODO Auto-generated method stub return null; } @Override public void destroyItem(View arg0, int arg1, Object arg2) { ((ViewPager) arg0).removeView((View) arg2); } @Override public boolean isViewFromObject(View arg0, Object arg1) { return arg0 == ((View) arg1); } @Override public Parcelable saveState() { return null; } public static Integer getItem(int position) { // TODO Auto-generated method stub return null; } } OnPageChangeListener; package com.example.pictures; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.support.v4.view.ViewPager; import android.support.v4.view.ViewPager.OnPageChangeListener; import android.view.View; import android.widget.Button; import android.widget.Toast; public class Pictures extends Activity implements OnPageChangeListener{ SoundManager snd; int sound1,sound2,sound3; View view=null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.picturespage); MyPagerAdapter adapter = new MyPagerAdapter(); ViewPager myPager = (ViewPager) findViewById(R.id.myfivepanelpager); myPager.setAdapter(adapter); myPager.setCurrentItem(0); myPager.setOnPageChangeListener(this); snd = new SoundManager(this); sound1 = snd.load(R.raw.sound1); sound2 = snd.load(R.raw.sound2); sound3 = snd.load(R.raw.sound3); } public void onPageScrollStateChanged(int arg0) { // TODO Auto-generated method stub } public void onPageScrolled(int arg0, float arg1, int arg2) { // TODO Auto-generated method stub } public void onPageSelected(int position) { // TODO Auto-generated method stub switch (position) { case 0: snd.play(sound1); break; case 1: snd.play(sound2); break; case 2: snd.play(sound3); break; case 3: Toast.makeText(this, "1", Toast.LENGTH_SHORT).show(); break; case 4: Toast.makeText(this, "2", Toast.LENGTH_SHORT).show(); break; case 5: Toast.makeText(this, "3", Toast.LENGTH_SHORT).show(); break; } } };

• Saving to SharedPreferences from custom DialogPreference

  - by Ronnie

  I've currently got a preferences screen, and I've created a custom class that extends DialogPreference and is called from within my Preferences. My preferences data seems store/retrieve from SharedPreferences without an issue, but I'm trying to add 2 more sets of settings from the DialogPreference. Basically I have two issues that I have not been able to find. Every site I've seen gives me the same standard info to save/restore data and I'm still having problems. Firstly I'm trying to save a username and password to my SharedPreferences (visible in the last block of code) and if possibly I'd like to be able to do it in the onClick(). My preferences XML that calls my DialogPreference: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <PreferenceCategory> <com.rone.optusmon.AccDialog android:key="AccSettings" android:title="Account Settings" android:negativeButtonText="Cancel" android:positiveButtonText="Save" /> </PreferenceCategory> </PreferenceScreen> My Preference Activity Class: package com.rone.optusmon; import android.app.AlertDialog; import android.content.Context; import android.content.DialogInterface; import android.os.Bundle; import android.preference.Preference; import android.preference.Preference.OnPreferenceClickListener; import android.preference.PreferenceActivity; import android.view.KeyEvent; public class EditPreferences extends PreferenceActivity { Context context = this; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.preferences); } } My Custom DialogPreference Class file: package com.rone.optusmon; import android.content.Context; import android.content.DialogInterface; import android.content.SharedPreferences; import android.preference.DialogPreference; import android.preference.PreferenceManager; import android.text.method.PasswordTransformationMethod; import android.util.AttributeSet; import android.view.View; import android.widget.CheckBox; import android.widget.CompoundButton; import android.widget.CompoundButton.OnCheckedChangeListener; import android.widget.EditText; import android.widget.LinearLayout; import android.widget.TextView; import android.widget.Toast; public class AccDialog extends DialogPreference implements DialogInterface.OnClickListener { private TextView mUsername, mPassword; private EditText mUserbox, mPassbox; CharSequence mPassboxdata, mUserboxdata; private CheckBox mShowchar; private Context mContext; private int mWhichButtonClicked; public AccDialog(Context context, AttributeSet attrs) { super(context, attrs); mContext = context; } @Override protected View onCreateDialogView() { @SuppressWarnings("unused") LinearLayout.LayoutParams params; LinearLayout layout = new LinearLayout(mContext); layout.setOrientation(LinearLayout.VERTICAL); layout.setPadding(10, 10, 10, 10); layout.setBackgroundColor(0xFF000000); mUsername = new TextView(mContext); mUsername.setText("Username:"); mUsername.setTextColor(0xFFFFFFFF); mUsername.setPadding(0, 8, 0, 3); mUserbox = new EditText(mContext); mUserbox.setSingleLine(true); mUserbox.setSelectAllOnFocus(true); mPassword = new TextView(mContext); mPassword.setText("Password:"); mPassword.setTextColor(0xFFFFFFFF); mPassbox = new EditText(mContext); mPassbox.setSingleLine(true); mPassbox.setSelectAllOnFocus(true); mShowchar = new CheckBox(mContext); mShowchar.setOnCheckedChangeListener(mShowchar_listener); mShowchar.setText("Show Characters"); mShowchar.setTextColor(0xFFFFFFFF); mShowchar.setChecked(false); if(!mShowchar.isChecked()) { mPassbox.setTransformationMethod(new PasswordTransformationMethod()); } layout.addView(mUsername); layout.addView(mUserbox); layout.addView(mPassword); layout.addView(mPassbox); layout.addView(mShowchar); return layout; // Access default SharedPreferences SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this); } public void onClick(DialogInterface dialog, int which) { mWhichButtonClicked = which; // if statement to set save/cancel button roles if (mWhichButtonClicked == -1) { Toast.makeText(mContext, "Save was clicked", Toast.LENGTH_SHORT).show(); mUserboxdata = mUserbox.getText(); mPassboxdata = mPassbox.getText(); // Save user preferences SharedPreferences settings = getDefaultSharedPreferences(this); SharedPreferences.Editor editor = settings.edit(); editor.putString("usernamekey", (String) mUserboxdata); editor.putString("passwordkey", (String) mPassboxdata); } else { Toast.makeText(mContext, "Cancel was clicked", Toast.LENGTH_SHORT).show(); } } } In my SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this); line, Eclipse says "The method getDefaultSharedPreferences(AccDialog) is undefined for the type AccDialog". I've attempted to change the context to my preferences class, use a blank context and I've also tried naming my SharedPrefs and using "getSharedPreferences()" as well. I'm just not sure exactly what I'm doing here. As I'm quite new to Java/Android/coding in general, could you please be as detailed as possible with any help, eg. which of my files I need to write the code in and whereabouts in that file should I write it (i.e. onCreate(), onClick(), etc) Edit: I will need to the preferences to be Application-wide accessible, not activity-wide. Thanks

• Android SDK emulator freezes on a Mac running OS X 10.6 Snow Leopard

  - by Donald Burr

  I'm having trouble running the Android SDK on both of my Macs running OS X 10.6.2 Snow Leopard. This appears to be a 64 bit vs. 32 bit issue, as Snow Leopard now defaults to 64-bit everything, including the Java virtual machine. I found this webpage with instructions on how to get the Android tools to run in the 32-bit Java VM, and I am now able to run the Android GUI tool to download SDK files, create AVM's, etc. However, when I try the Hello World tutorial and get to the point where I run my application under the Android emulator, everything goes south. The emulator appears to start but it hangs (spinning beachball of death cursor) without displaying anything. (This only hangs the emulator; the rest of the system still works fine.) If I follow the exact same steps (minus the 32-bit java hack) in a Windows virtual machine, everything works fine. Googling didn't yield anything useful (except for the 32-bit java hack I spoke of earlier). This occurs on both my Mac Pro tower and 13" MacBook Pro. Does anyone have any suggestions?

• Kindle Fire: PopupMenu$OrientationChangeListener leak

  - by dokkaebi

  I have a little popup menu that anchors on a button in the action bar. This works well on 3.0/3.1 Xoom and Galaxy tabs, and a 4.1 Nexus 7. However, on a 7" Fire HD (this one), I get an error about a leaked intent receiver when exiting the application. The error occurs only if the menu was not opened during that run. There is no mention of OrientationChangeListener in the one copy of the source I've found; I suspect Amazon has a different implementation. Questions: Has anyone encountered this? Does anyone know of a workaround or a fix? (Where) can I find Amazon's source code? Finally, (shudder) how important is it that I don't leak a receiver on application exit? Here is the menu xml: <?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/menu_profile" android:title="@string/menu_item_profile" ></item> <item android:id="@+id/menu_logout" android:title="@string/menu_item_logout" ></item> </menu> This is where I register it: @Override public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.main_menu, menu); MenuItem login = menu.findItem(R.id.menu_login); Button button = (Button) login.getActionView().findViewById(R.id.login); button.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { profileMenu.show(); } }); // profileMenu is an instance field profileMenu = new PopupMenu(this, button); inflater.inflate(R.menu.profile_menu, profileMenu.getMenu()); profileMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() { public boolean onMenuItemClick(MenuItem item) { // there was code here, but I removed it all and the problem persists return false; } }); return true; } Here is the full stack trace: 10-21 20:55:28.461: E/ActivityThread(4526): Activity **.app.ListActivity has leaked IntentReceiver android.widget.PopupMenu$OrientationChangeListener@422d77e0 that was originally registered here.

• Application stops on back button in new activity

  - by Bruno Almeida

  I have this application, that have a listView, and when I click in a item on listView, it opens a new activity. That works fine! But, if I open the new activity and than press the "back button" the application "Unfortunately, has stopped". Is there something I'm doing wrong? Here is my code: First activity: public class AndroidSQLite extends Activity { private SQLiteAdapter mySQLiteAdapter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ListView listContent = (ListView)findViewById(R.id.contentlist); mySQLiteAdapter = new SQLiteAdapter(this); mySQLiteAdapter.openToRead(); Cursor cursor = mySQLiteAdapter.queueAll(); startManagingCursor(cursor); String[] from = new String[]{SQLiteAdapter.KEY_NOME,SQLiteAdapter.KEY_ID}; int[] to = new int[]{R.id.text,R.id.id}; SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this, R.layout.row, cursor, from, to); listContent.setAdapter(cursorAdapter); listContent.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Toast.makeText(getBaseContext(), id + "", Toast.LENGTH_LONG).show(); Intent details = new Intent(getApplicationContext(),DetailsPassword.class); startActivity(details); } }); mySQLiteAdapter.close(); } } Second Activity: public class DetailsPassword extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView text = new TextView(getApplicationContext()); text.setText("Text to show"); setContentView(text); } } // ===== EDITED ===== here is the Stack Track 10-30 08:55:05.744: E/AndroidRuntime(28046): FATAL EXCEPTION: main 10-30 08:55:05.744: E/AndroidRuntime(28046): java.lang.RuntimeException: Unable to resume activity {com.example.sqliteexemple2/com.example.sqliteexemple2.AndroidSQLite}: java.lang.IllegalStateException: trying to requery an already closed cursor android.database.sqlite.SQLiteCursor@4180a370 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.ActivityThread.performResumeActivity(ActivityThread.java:2701) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.ActivityThread.handleResumeActivity(ActivityThread.java:2729) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1250) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.os.Handler.dispatchMessage(Handler.java:99) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.os.Looper.loop(Looper.java:137) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.ActivityThread.main(ActivityThread.java:4931) 10-30 08:55:05.744: E/AndroidRuntime(28046): at java.lang.reflect.Method.invokeNative(Native Method) 10-30 08:55:05.744: E/AndroidRuntime(28046): at java.lang.reflect.Method.invoke(Method.java:511) 10-30 08:55:05.744: E/AndroidRuntime(28046): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:791) 10-30 08:55:05.744: E/AndroidRuntime(28046): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:558) 10-30 08:55:05.744: E/AndroidRuntime(28046): at dalvik.system.NativeStart.main(Native Method) 10-30 08:55:05.744: E/AndroidRuntime(28046): Caused by: java.lang.IllegalStateException: trying to requery an already closed cursor android.database.sqlite.SQLiteCursor@4180a370 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.Activity.performRestart(Activity.java:5051) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.Activity.performResume(Activity.java:5074) 10-30 08:55:05.744: E/AndroidRuntime(28046): at android.app.ActivityThread.performResumeActivity(ActivityThread.java:2691) 10-30 08:55:05.744: E/AndroidRuntime(28046): ... 10 more

• android: how do i open another app from my app?

  - by mtmurdock

  I understand how to use intents and startActivity() when opening another activity within my own app, but how do you start a different app? specifically: -how do you determine if the user has the needed app installed on their device? -how do you start that app? -how do you pass parameters to that app? -how do you find all this info out for a specific app (say Adobe reader, or google maps)?

• Routing audio to Bluetooth Headset (non-A2DP) on Android

  - by Jayesh

  I have a non-A2DP single ear BT headset (Plantronics 510) and would like to use it with my Android HTC Magic to listen to low quality audio like podcasts/audio books. After much googling I found that only phone call audio can be routed to the non-A2DP BT headsets. (I would like to know if you have found a ready solution to route all kinds of audio to non-A2DP BT headsets) So I figured, somehow programmatically I can channel the audio to the stream that carries phone call audio. This way I will fool the phone to carry my mp3 audio to my BT headset. I wrote following simple code. import android.content.*; import android.app.Activity; import android.os.Bundle; import android.media.*; import java.io.*; import android.util.Log; public class BTAudioActivity extends Activity { private static final String TAG = "BTAudioActivity"; private MediaPlayer mPlayer = null; private AudioManager amanager = null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); amanager = (AudioManager) getSystemService(Context.AUDIO_SERVICE); amanager.setBluetoothScoOn(true); amanager.setMode(AudioManager.MODE_IN_CALL); mPlayer = new MediaPlayer(); try { mPlayer.setDataSource(new FileInputStream( "/sdcard/sample.mp3").getFD()); mPlayer.setAudioStreamType(AudioManager.STREAM_VOICE_CALL); mPlayer.prepare(); mPlayer.start(); } catch(Exception e) { Log.e(TAG, e.toString()); } } @Override public void onDestroy() { mPlayer.stop(); amanager.setMode(AudioManager.MODE_NORMAL); amanager.setBluetoothScoOn(false); super.onDestroy(); } } As you can see I tried combinations of various methods that I thought will fool the phone to believe my audio is a phone call: Using MediaPlayer's setAudioStreamType(STREAM_VOICE_CALL) using AudioManager's setBluetoothScoOn(true) using AudioManager's setMode(MODE_IN_CALL) But none of the above worked. If I remove the AudioManager calls in the above code, the audio plays from speaker and if I replace them as shown above then the audio stops coming from speakers, but it doesn't come through the BT headset. So this might be a partial success. I have checked that the BT headset works alright with phone calls. There must be a reason for Android not supporting this. But I can't let go of the feeling that it is not possible to programmatically reroute the audio. Any ideas? P.S. above code needs following permission <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>

• ImageView bounds are larger than expected in android layout

  - by Hamy

  Hey all, This is a layout that I have defined in an app. As you can see, I would like the TextView "@details/image_time_counter" to be aligned with the bottom right of the image. Unfortunately, this is currently what shows - app - hierarchy viewer all - HV part 2. HierarchyViewer reports that the ImageView has bounds much bigger than what I am expecting. Can anyone explain these bounds, or just tell me how to make the bounds be the same as the image size? Thanks, Hamy <RelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> </RelativeLayout>

• Android compatibility with Restlet/JSON/Jackson

  - by Cookie

  Hi there, I'm currently working on a webservice-client for Android. I'm using a Java client library which provides an abstraction for interaction with the service. The client library works on normal machines. However, when I use the classes in my Android project, some calls don't return a result on Android, the background-service stops working at the first of those commands. Wireshark shows a tcp exchange, the server gets the requests. There is no exceptions or anything. Something in the serialization/deserialization semms not to work. I'm using the newest version of Jackson libraries (1.5.3) and the restlet jar in the android edition. Is there any known problems with Jackson and Android? Which code and libraries are compatible with Android? Thanks in advance.

• Fail to load NPAPI plugin in Google Chrome on Mac OS X

  - by Roman

  I have been trying to get Google Chrome (6.0.401.1 dev) on Mac OS X to load an NPAPI plugin without success so far. I have been working around the npsimple example from here: http://git.webvm.net/?p=npsimple. Using gcc on Mac and VC++ 2008 on Windows I managed to get it running on Safari and Firefox on Mac OS X and Firefox and Google Chrome on Windows, but not on Google Chrome on Mac OS X. When trying to debug Google Chrome on Mac OS X it seemed Google Chrome was briefly dyld-loading (and immediately dyld-unloading) the plugin on startup, but without actually looking-up any symbols within the plugin or calling any of the functions. It seemed to be doing that for every plugin, though. Also, when loading a page with the embed-tag for the plugin, Google Chrome did not seem to even dyld-load the plugin and no functions were called (not even NP_GetEntryPoints). Google Chrome also does not output any error message, it just simply does not load the plugin. I am not sure I caught everything with gdb because of Google Chrome using different processes, but I have also tried all the switches like --no-sandbox, --single-process and --plugin-startup-dialog (which incidentally does not seem to work at all on Mac OS X). I also made sure the architecture of the binary matches (i.e. 32-bit for Google Chrome). Has anybody had similar problems before? Is there anything I am missing here, like a gcc switch when compiling or something? Any help would be greatly appreciated.

• Android: Image displayed at Webview from Url with high quality loss

  - by Merlino

  I want to display an image from an url with an Webview at Android. With Android phones with Version 1.5 and 1.6 there is no problem. but the same pic and the same code on an AndroidPhone with Version 2.0 and the pic is totaly pixelated. Like Android is resizing the image first to a smaller one and then resizing it back to "normal" size. Unfortunately its important to display the pic without any quality loss. I tried to integrate it in the sourcefolder to show it as an normal image, but at Android 2.0 i get an exception because the image is to big. (At Android 1.6 there is no problem) Any ideas how i can display the image without quality loss with Android 2.0 ?

• Fetching templates via API. Who provides this service?

  - by Guandalino

  I'm mainly a server side developer. I'm not a designer, even if I understand web layouts, grids, CSS, typography, valid markup, etc. and I'm able to do some graphic work too (almost). It just takes a lot of time and the result is not always beautiful. I know there are tons of website templates sites out there, and I'd like to use their designs as a starting point for my customers' works, giving them the possibility to choose the design they like more. I'd just prefer to show the templates catalog to customers from within my site, fetching templates info (screenshots, description, etc) from a remote server using an API. TemplateMonster.com provides, or provided, such API. But the service responds with "Unauthorized usage". Are there other sites offering this kind of retrieval service?

  Hi folks, I have Android development eclipse setup on Mac OS X. I recently did Android SDK upgrade from 1.5 to available versions such as 1.6, 2.0.1 and 2.1 and docs.
