  • Video not playing on android webview

    - by rand
    I am working with an Android and PhoneGap application and am using the HTML5 video tag to play videos on my web page. When I play the video is not visible and video is not playing itself. How can I play a HTML5 video on Android? Code for the same given below <!DOCTYPE HTML> <html> <head> <script type="text/javascript" charset="utf-8" src="cordova-1.8.1.js"></script> <meta http-equiv="content-type" content="text/html; charset="> <title></title> </head> <body > <video id="video" autobuffer height="240" width="360" onclick="this.play();> <source src="test.mp4"> <source src="test.mp4" type="video/webm"> <source src="test.mp4" type="video/ogg"> </video> <div id="msg"></div> <script type="text/javascript"> </script> </body> </html> and the activity class onCreate method-- public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); final WebView webView = (WebView) findViewById(R.id.webview); WebSettings webSettings = webView.getSettings(); webSettings.setLayoutAlgorithm(LayoutAlgorithm.NARROW_COLUMNS); webView.getSettings().setJavaScriptEnabled(true); webSettings.setBuiltInZoomControls(true); webSettings.setPluginState(PluginState.ON); webView.getSettings().setPluginsEnabled(true); webSettings.setAllowFileAccess(true); webView.loadUrl("file:///android_asset/www/html5videoEvents.html"); }

  • Dice Emulation - ImageView

    - by Michelle Harris
    I am trying to emulate dice using ImageView. When I click the button, nothing seems to happen. I have hard coded this example to replace the image with imageView4 for debugging purposes (I was making sure the random wasn't fail). Can anyone point out what I am doing wrong? I am new to Java, Eclipse and Android so I'm sure I've probably made more than one mistake. Java: import java.util.Random; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter; import android.widget.ImageView; import android.widget.Spinner; import android.widget.Toast; public class Yahtzee4Activity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Spinner s = (Spinner) findViewById(R.id.spinner); ArrayAdapter adapter = ArrayAdapter.createFromResource( this, R.array.score_types, android.R.layout.simple_spinner_dropdown_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); s.setAdapter(adapter); } public void onMyButtonClick(View view) { ImageView imageView1 = new ImageView(this); Random rand = new Random(); int rndInt = 4; //rand.nextInt(6) + 1; // n = the number of images, that start at index 1 String imgName = "die" + rndInt; int id = getResources().getIdentifier(imgName, "drawable", getPackageName()); imageView1.setImageResource(id); } } XML for the button: <Button android:id="@+id/button_roll" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/roll" android:onClick="onMyButtonClick" />

  • Android Camera intent creating two files

    - by Kyle Ramstad
    I am making a program that takes a picture and then shows it's thumbnail. When using the emulator all goes well and the discard button deletes the photo. But on a real device the camera intent saves the image at the imageUri variable and a second one that is named like if I had just opened up the camera and took a picture by itself. private static final int CAMERA_PIC_REQUEST = 1337; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.camera); //start camera values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, "New Picture"); values.put(MediaStore.Images.Media.DESCRIPTION,"From your Camera"); imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); image = (ImageView) findViewById(R.id.ImageView01); Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); startActivityForResult(intent, CAMERA_PIC_REQUEST); //save the image buttons Button save = (Button) findViewById(R.id.Button01); Button close = (Button) findViewById(R.id.Button02); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == CAMERA_PIC_REQUEST && resultCode == RESULT_OK) { try{ thumbnail = MediaStore.Images.Media.getBitmap(getContentResolver(), imageUri); image.setImageBitmap(thumbnail); } catch(Exception e){ e.printStackTrace(); } } else{ finish(); } } public void myClickHandler(View view) { switch (view.getId()) { case R.id.Button01: finish(); break; case R.id.Button02: dicard(); } } private void dicard(){ getContentResolver().delete(imageUri, null, null); finish(); }

  • Relatively simple task: How do I pass back the selected item from one activity to another?

    - by Brian D
    I have two activities: one displays an image and a button, the other displays a photo gallery. I want to be able to select any of the images in the gallery and then display them on the first activity in place of the default image. public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.gallery); Gallery g = (Gallery) findViewById(R.id.gallery); g.setAdapter(new ImageAdapter(this)); g.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView parent, View v, int position, long id) { Toast.makeText(PhotoGallery.this, "Position: " + id, Toast.LENGTH_SHORT).show(); Intent intent=new Intent(); intent.putExtra("PictureID", position); setResult(RESULT_OK, intent); finish(); } }); } Am I even close here? I'm not quite sure what to do with any string or int I would attach to the Intent -- can I attach the object itself? I'd much rather pass back at minimum the string name of the resource (image), but the only thing I can seem to figure out right now is how to pass back the position of the picture ... not a great solution. I can clarify more if necessary -- thanks.

  • Do not get the rootLayoutContainer in a Fragment (Android 3.0 Preview)

    - by Hawk66
    Hello, I'm currently getting into the fragment API of the Android 3.0 Preview and have built the following minimal coding: I have an Activty, which shall embed Fragment(s), which is currently implemented like this: public class Cockpit extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.cockpit); } public static class InfoFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment ViewGroup infoFragmentRoot = (ViewGroup) getActivity().findViewById( R.id.infoFragmentRoot) ; return inflater.inflate(R.id.infoFragment, container, false); } } } The corresponding layout of the activity: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <fragment android:name="test.android.ui.cockpit.Cockpit$InfoFragment" android:id="@+id/infoFragment" android:layout_weight="1" android:layout_width="10dp" android:layout_height="match_parent" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="12dp" android:id="@+id/infoFragmentRoot" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> </LinearLayout> </fragment> Now, I do not understand why the ViewGroup container in the onCreateView() in the internal class InfoFragment is a nullpointer, nor do I understand, why ViewGroup infoFragmentRoot = (ViewGroup) getActivity().findViewById( R.id.infoFragmentRoot) ; returns also null. Thanks for feedback.

  • Not able to play videos (from youtube) in WebView

    - by user1205193
    I am using a webview to display a video (could be from youtube or vimeo) in my app. In order to not load the video webpages in the default Android Browser, I am also extending the WebViewClient so I can override the shouldOverrideUrlLoading method. This way the video webpage loads successfully in the WebView. However, when I click on the embedded video on the WebView, it does not play. If I do not override the shouldOverrideUrlLoading method, and let the video webpages load in the default Android browser, the videos work just fine. Any ideas why the videos are not working in the WebView? Also, the main reason why I overrode the shouldOverrideUrlLoading method is because if I do not do that, then when I exit the Android browser to come back to my activity (by hitting the back button on the phone), I see a white screen. Upon hitting the back button twice, I am able to get back to my Activity. I am using the emulator to do this test. Here is my code: public class YoutubeLink extends Activity { WebView myWebView; String video_url; private class HelloWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } } @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.youtubelink); //Retrieving data from ListSample.java Bundle extras = getIntent().getExtras(); if(extras !=null) { video_url = extras.getString("video_url"); Log.d("inside YoutubeLink.java", video_url); } myWebView = (WebView) findViewById(R.id.web); myWebView.getSettings().setJavaScriptEnabled(true); myWebView.setWebViewClient(new HelloWebViewClient()); myWebView.loadUrl(video_url); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if ((keyCode == KeyEvent.KEYCODE_BACK) && myWebView.canGoBack()) { myWebView.goBack(); return true; } return super.onKeyDown(keyCode, event); }}

  • How to putExtra() in Searchable Dictionary Example

How can I putExtra data with a click on a search suggestion? Thanks

  • Getting an updated location in Android

    - by jul
    Hi, I'm using the code shown below to get an updated value for location every time a button is clicked. When my activity is resumed I get an update every second, so that when I call getLastKnownLocation I expect to have a location that have been updated in the last second. Is that the correct way to do that? I would expect the onLocationChanged event to be triggered every time I execute a 'geo fix' command (or max after 1s since I request update every 1s), but it's only triggered the first time. Why? Any help/suggestion welcome! Thanks package org.digitalfarm.atable; ... public class Atable extends Activity { private Button mSearchButton; private TextView mytext; private LocationManager locationManager; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mSearchButton = (Button)this.findViewById(R.id.button); mytext = (TextView) findViewById(R.id.dude); locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); final Criteria criteria = new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_FINE); mSearchButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { String provider = locationManager.getBestProvider(criteria, true); Location location = locationManager.getLastKnownLocation(provider); } }); } //Start a location listener LocationListener onLocationChange=new LocationListener() { public void onLocationChanged(Location loc) { //sets and displays the lat/long when a location is provided String latlong = "Lat: " + loc.getLatitude() + " Long: " + loc.getLongitude(); mytext.setText(latlong); } public void onProviderDisabled(String provider) { // required for interface, not used } public void onProviderEnabled(String provider) { // required for interface, not used } public void onStatusChanged(String provider, int status, Bundle extras) { // required for interface, not used } }; //pauses listener while app is inactive @Override public void onPause() { super.onPause(); locationManager.removeUpdates(onLocationChange); } //reactivates listener when app is resumed @Override public void onResume() { super.onResume(); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,100.0f,onLocationChange); } }

  • Spinner original text

    - by user1696863
    I'm trying my Spinner to display "Select City" before the Spinner has itself been clicked by the user. How can I do this? My current XML code is: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:custom="http://schemas.android.com/apk/res/com.olacabs.customer" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/page_background" android:orientation="vertical" > <TextView android:id="@+id/textView1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@android:color/darker_gray" android:gravity="center" android:paddingBottom="4dp" android:paddingTop="4dp" android:text="@string/rate_card" android:textColor="@color/white" android:textSize="20dp" custom:customFont="litera_bold.ttf" /> <Spinner android:id="@+id/select_city" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginTop="40dp" android:prompt="@string/selectCity" /> </LinearLayout> Also, what does android:spinnerMode exactly do. I tried changing its value to dropdown but nothing happened and the application still showed a popup dialogue. My activity that implements this XML file is: public class RateCardActivity extends OlaActivity { public void onCreate(Bundle bundle) { super.onCreate(bundle); setContentView(R.layout.rate_card); Spinner spinner = (Spinner) findViewById(R.id.select_city); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.select_city, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); } }

  • eclipse error with android: id cannot be resolved or is not a field

    - by Jaynathan Leung
    Hi, I just started playing around with android development, and already with just an attempt at making a button, I have encountered a problem. The error I'm given in the following code is right on "R.id.button1". It says id cannot be resolved or is not a field. Do I need to manually reference every single object I make in the layout xml file? I found that this did work, but it does seem to be a bit much for every button I want to make... package com.example.helloandroid; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; public class HelloAndroid extends Activity { /** Called when the activity is first created. */ private Button button1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); button1 = (Button)findViewById(R.id.button1); button1.setOnClickListener(new OnClickListener() { public void onClick(View v) { finish(); } }); } }

  • Spinner activity not working

    - by user1696863
    I'm trying to create an activity, RateCardActivity, which has a spinner in it. My layout file for RateCardActivity is rate_card. My RateCardActivity looks like the following. public class RateCardActivity { public void onCreate(Bundle bundle) { super.onCreate(bundle); setContentView(R.layout.rate_card); Spinner spinner = (Spinner) findViewById(R.id.select_city); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.select_city, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); } } The layout file rate_card is: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:custom="http://schemas.android.com/apk/res/com.olacabs.customer" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TextView android:id="@+id/textView1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@android:color/darker_gray" android:gravity="center" android:paddingBottom="4dp" android:paddingTop="4dp" android:text="@string/rate_card" android:textColor="@color/white" android:textSize="20dp" custom:customFont="litera_bold.ttf" /> <Spinner android:id="@+id/select_city" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout> The RateCardActivity is called from another activity using an intent (I'm sure there is nothing wrong with that part of the code as when I substitute RateCardActivity with another activity, the application works fine). When I try to open the RateCardActivity in the application in emulator, the application crashes and I got the message "The application has stopped unexpectedly. Please try again later." I can't seem to understand what I'm doing wrong, and want to know how to correct this?

  • How do I insert this subclass into my code?

    - by BamsBamx
    This is a very noob question so I hope you can help me with this... This is my built code: public class PantallaOpciones extends PreferenceActivity { private SharedPreferences preferences; @Override public void onCreate(Bundle savedInstanceState) { preferences = PreferenceManager.getDefaultSharedPreferences(this); findPreference("speechkeycode").setOnPreferenceClickListener(keycodedialog); Preference.OnPreferenceClickListener keycodedialog = new Preference.OnPreferenceClickListener(){ public boolean onPreferenceClick(Preference preference){ keycodedialog(); return false; }}; } private void keycodedialog(){ final Dialog dialog = new Dialog(this); dialog.setContentView(R.layout.keycodedialog); dialog.setTitle("Speech keycode"); final TextView keypresstext = (TextView) findViewById(R.id.keypresstext); Button savekeycode = (Button) dialog.findViewById(R.id.btnsavekeycode); savekeycode.setOnClickListener(new OnClickListener() { public void onClick(View v) { dialog.dismiss(); } }); Button resetkeycode = (Button) dialog.findViewById(R.id.btnresetvalue); resetkeycode.setOnClickListener(new OnClickListener() { public void onClick(View v) { dialog.dismiss(); } }); dialog.show(); } Okay, now I want to add this code to dialog: public boolean onKeyDown(int keyCode, KeyEvent event) { //SOME STUFF return super.onKeyDown(keyCode, event); } So I want to listen to a keypress when dialog is opened and show the keycode of hardware press by using textview.settext()... The question is: how do I insert public boolean onKeyDown into the dialog??? Thanks in advance!! :)

  • Showing Loading screen during REST service request in android app ?

    - by sat
    Currently here is what I am following, As soon as my app is launched, I have to send a request for REST service, It will take little time , so I thought of showing loading screen, In onCreate() of my Activity , first thing will be to show loading screen(progress dialog) , And I kick off the background Activity using AsyncTask , i.e. requesting for REST service and onPostexecute() I close the dialog and then I do setContentView(myxml); and update the UI . Can this approach be improved ? Problem which I faced was , Sometimes , Garbage collector may start(due to various reasons) and my app hangs at loading screen forever , because of Garbage collector , even request for REST service is not sent and because of it some wake up call comes and rest is disaster and Force close. But sometimes even ForceClose doesnot come fast , may be because of GC. so I cannot even go back and stuck in loading screen. Only thing which I can do at that point is to come back HOME. After that If I come back to my app its still loading , so definitely this approach seems to be a bad design. Whats the right approach ?

  • Android: Associating Browser to File Type in App

    - by tekmunki
    I'm attempting to write a simple app that associates a file type to the browser; this is assuming the browser will open the file locally... If this doesn't work, the local file - editor will be fine. I have an option of auto-mailing .ELC files from a custom app, they are basically html formatted TEXT or TXT only files; I would like to associate the .elc extension so that it will open direct from mail rather than just "Save to SD Card" as a mail option. Here's the code I'm at right now; AndroidManifest.xml: ELCViewer.java: package com.tekmunki.ELCViewer; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class ELCViewer extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); tv.setText("ELC Viewer Installed! Now, when you receive the ELC files, they will open in the browser."); setContentView(tv); } } 1) How do I make the browser associated with the ELCViewer Activity? (Do I need to make a second activity, or can that all be done in the manifest?) 2) How do I make it persist after the app has been ran once?
