• Setting up MySQL database replication [without restarting mysql]

  - by FunkyChicken

  I'm trying to setup MySQL db replication, it seems pretty straight forward. I was using this tutorial: http://www.howtoforge.com/mysql_database_replication Now I run a rather large MySQL database for a very large website, and in this tutorial it asks me to restart MySQL to apply the new settings in the /etc/my.cnf file. I'm try to avoid that step at all costs, as I know that restarting MySQL can take a few minutes on my machine (due to large logs/dbs), and I don't want any downtime. Is there a way to apply the necessary settings WITHOUT fully restarting Mysql?

• Take all fields in a database table and put them straight into a text file

  - by DalexL

  I have an database file (mdb) file that contains a dictionary of words. A couple thousand of them. I just need the words (in the order they are already in) put into a text file. Currently they have ID's associated with them (e.g. 1, 2, 3) but I don't need it. I just need the words. What is the best way to do this? Actually, if somebody is able to find a dictionary of English words (something along the lines of a scrabble dictionary) that is free online, I'll accept that too. I just can't seem to find any good ones online.

• Looking for a central image database and tagging system for a group of users

  - by jstarek

  I'm doing IT support for a small volunteer organisation who needs to centrally store and organize around 2500 photos. Can anyone here recommend a database or similar system which matches the following criteria: Intuitive to use for users with little computer experience Multi-user support, ideally with integration in our existing LDAP user directory Should have a web-interface Not a hosted solution like Picasa (because we have a rather slow internet connection with very slow upload) Should allow tagging of images, sorting by various criteria and storing copyright information If there are native GNOME and/or Windows clients for the tool, that would be a great benefit. Many thanks in advance!

• Using mongodump with an auth enabled mongodb server

  - by bb-generation

  I'm trying to do a daily backup of my mongodb server (auth enabled) using the mongodump tool. mongodump provides two parameters to set the credentials: -u [ --username ] arg username -p [ --password ] arg password Unfortunately they don't provide any parameter to read the password from stdin. Therefore everytime I run this command, everyone on the server can read the password (e.g. by using ps aux). The only workaround I have found is stopping the database and directly accessing the database files using the --dbpath parameter. Is there any other solution which allows me to backup the mongodb database without stopping the server and without "publishing" my password? I am using Debian squeeze 6.0.5 amd64 with mongodb 1.4.4-3.

• Installing Oracle11gr2 on redhat linux

  - by KItis

  I have basic question about installing applications on linux operating system. i am going to express my issue considering oracle db installation as a example. when installing oracle database , i created a user group called dba and and user in this group called ora112. so this users is allowed to install database. so my question is if ora112 uses umaks is set to 077, then no other uses will be able to configure oracle database. why do we need to follow this practice. is it a accepted procedure in application installation on Linux. please share your experience with me. thanks in advance for looking into this issue say i install java application on this way. then no other application which belongs to different user account won't be able use java running on this computer because of this access restriction.

  hi there i have been searching the web for a connection between my android simulator and a mysql db. I've fount that you can't connect directly but via a webserver. The webserver wil handle my request from my android. I fount the following code on www.helloandroid.com But i don't understand. If i run this code on the simulator nothing happens.

• AIDL based two way communication

  - by sshasan

  I have two apps between which I want some data exchanged. As they are running in different processes, so, I am using AIDL to communicate between them. Now, everything is happening really great in one direction (say my apps are A and B) i.e. data is being sent from A to B but, now I need to send some data from B to A. I noticed that we need to include the app with the AIDL in the build path of app where the AIDL method will be called. So in my case A includes B in its build path. For B to be able to send something to A, by that logic, B would need A in its build path. This would create a cycle. I am stuck at this point. And I cannot think of a work around this loop. Any help would be greatly appreciated :) . Thanks! ----EDIT---- So, I following the advice mentioned in one of the comments below, I have the following code In the IPCAIDL project the AIDL file resides, its contents are package ipc.android.aidl; interface Iaidl{ boolean pushBoolean(boolean flag); } This project is being used as a library in both the IPCServer and the IPC Client. The IPCServer Project has the service which defines what happens with the AIDL method. The file is booleanService.java package ipc.android.server; import ipc.android.aidl.Iaidl; import android.app.Service; import android.content.Intent; import android.os.IBinder; import android.os.RemoteException; import android.util.Log; public class booleanService extends Service { @Override public IBinder onBind(Intent intent) { return new Iaidl.Stub() { @Override public boolean pushBoolean(boolean arg0) throws RemoteException { Log.i("SERVER(IPC AIDL)", "Truth Value:"+arg0); return arg0; } }; } } The IPCClient file which calls this method is package ipc.android.client2; import ipc.android.aidl.Iaidl; import android.app.Activity; import android.content.ComponentName; import android.content.Context; import android.content.Intent; import android.content.ServiceConnection; import android.os.Bundle; import android.os.IBinder; import android.os.RemoteException; import android.view.View; import android.widget.Button; public class IPCClient2Activity extends Activity { Button b1; Iaidl iAIDL; boolean k = false; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); bindService(new Intent("ipc.android.server.booleanService"), conn, Context.BIND_AUTO_CREATE); startService(new Intent("ipc.android.server.booleanService")); b1 = (Button) findViewById(R.id.button1); b1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if(k){ k = false; } else{ k = true; } try { iAIDL.pushBoolean(k); } catch (RemoteException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }); } private ServiceConnection conn = new ServiceConnection() { @Override public void onServiceDisconnected(ComponentName name) { // TODO Auto-generated method stub } @Override public void onServiceConnected(ComponentName name, IBinder service) { iAIDL = Iaidl.Stub.asInterface(service); } }; } The manifest file for IPCServer includes the declaration of the service.

• Tutorials and libraries for OpenGL-ES games on Android

  - by user197141

  What tutorials and libraries are available which can help beginners to develop 2D and 3D games on Android using OpenGL-ES? I'm looking for tutorials which can help me learn OpenGL-ES, and I'm looking for OpenGL-ES libraries which can make life easier for beginners in OpenGL-ES. Since Android is still small, I guess it may be help-full to read iPhone OpenGL-ES tutorials as well, as I suppose the OpenGL-ES functionality is much the same. I have found the following useful information which I would have liked to share: Android tutorials: Basic tutorial covering polygons, no textures anddev forum with some tutorials Other Android OpenGL-ES information: Google IO lecture regarding games, not much OpenGLES The The Khronos Reference Manual is also relevant to have, but its not exactly the best place to start. iPhone OpenGL-ES tutorials (where the OpenGl-ES information is probably useful): http://web.me.com/smaurice/AppleCoder/iPhone_OpenGL/Archive.html http://iphonedevelopment.blogspot.com/2009/05/opengl-es-from-ground-up-table-of.html As for libraries which a beginner might use to get a simpler hands-on experience with OpenGL-ES, I have only found Rokon, which is recently started, thus has many holes and bugs. And it's gnuGPL licensed (at the moment) which means it cannot be used, if we wish to sell our games. What else is out there?

• Android multiple email attachment using Intent question

  - by yyyy1234

  Hi, I've been working on Android program to send email with attachment (image file , audio file , etc) using Intent with (ACTION_SEND) . THe program is working when email has a single attachment. I used Intent.putExtra( android.content.Intent.EXTRA_STREAM, uri) to attach the designated image file to the mail and it is wokring fine , the mail can be delivered through Gmail . However, when I tried to have multiple images attached to the same mail by calling Intent.putExtra( android.content.Intent.EXTRA_STREAM, uri) multiple times, it failed to work. None of the attachment show up in the email . I searched the SDK documentation and Android programming user group about email attachment but cannot find any related info. However, I've discovered that there's another intent constnat ACTION_SEND_MULTIPLE (available since API level 4 ) which might meet my requirement. Based on SDK documentation, it simply states that it deliver multiple data to someone else , it works like ACTION_SEND , excpet the data is multiple. But I still could not figure out the correct usage for this command. I tried to delcare intent with ACTION_SEND_MULTIPLE , then call putExtra(EXTRA_STREAM, uri) multiple times to attach multiple images , but I got the same errnoenous result just like before, none of the attachment show up in the email. Has anyone tried with ACTION_SEND_MULTIPLE and got it working with multiple email attachment ? Thanks very much for your help. Regards, yyyy1234

• android.intent.action.SCREEN_ON doesn't work as a receiver intent filter

  - by Jim Blackler

  I'm trying to get a BroadcastReceiver invoked when the screen is turned on. In my AndroidManifest.xml I have specified : <receiver android:name="IntentReceiver"> <intent-filter> <action android:name="android.intent.action.SCREEN_ON"></action> </intent-filter> </receiver> However it seems the receiver is never invoked (breakpoints don't fire, log statements ignored). I've swapped out SCREEN_ON for BOOT_COMPLETED for a test, and this does get invoked. This is in a 1.6 (SDK level 4) project. A Google Code Search revealed this, I downloaded the project and synced it, converted it to work with latest tools, but it too is not able to intercept that event. http://www.google.com/codesearch/p?hl=en#_8L9bayv7qE/trunk/phxandroid-intent-query/AndroidManifest.xml&q=android.intent.action.SCREEN_ON Is this perhaps no longer supported? Previously I have been able to intercept this event successfully with a call to Context.registerReceiver() like so registerReceiver(new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { // ... } }, new IntentFilter(Intent.ACTION_SCREEN_ON)); However this was performed by a long-living Service. Following sage advice from CommonsWare I have elected to try to remove the long-living Service and use different techniques. But I still need to detect the screen off and on events.

• Android Share - Facebook SDK - ShareActionProvider

  - by Vlasto Benny Lava

  I am trying to implement sharing a simple string inside my application. Obviously everything other than Facebook works. As far as I know, now I have to use their Facebook SDK to post statuses on a wall. However, if I do implement it using their SDK, is there a way to have it incorporated into the chooser (default or ShareActionProvider) and somehow override it and insert the Facebook SDK's implementation? Or do I have to create a dedicated button? //EDIT package com.example.shareactionproviderdemo; import android.app.Activity; import android.content.Intent; import android.os.Bundle; public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Intent sharingIntent = new Intent(Intent.ACTION_SEND); sharingIntent.setType("text/plain"); sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Test message"); startActivity(Intent.createChooser(sharingIntent, "Share using")); } }

• Simple Android Binary Text Clock

  Hello, I want to create a simple android binary clock but my application crashes. I use 6 textview fields: 3 for the decimal and 3 for the binary representation of the current time (HH:mm:ss).

• Android Launcher Shortcuts

  - by Tim

  I have made a simple punch in / punch out time clock application. I want to add the user the option of making a shortcut on the homescreen that will toggle the state of the app(time out / time in) but I don't want this shortcut to open up the app on the screen at all. here is my setupShortcut() private void setupShortcut() { Intent shortcutIntent = new Intent(this, Toggle.class); // shortcutIntent.setClassName(this, Toggle.class.getName()); shortcutIntent.putExtra(EXTRA_KEY, "ToggleShortcut"); shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); Intent intent = new Intent(); intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent); intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "ToggleShortcut"); Parcelable iconResource = Intent.ShortcutIconResource.fromContext(this, R.drawable.app_sample_code); intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconResource); setResult(RESULT_OK, intent); } Toggle.class is an activity that toggles the state for me. In the manifest I have these settings on it <activity android:name=".Toggle" android:exported="true" android:theme="@android:style/Theme.Translucent.NoTitleBar"> As it is now I can create a shortcut on the home screen then press it. The first time I press it it starts the Toggle activity and completes it fine, but it also opens up the TimeClock activity on the screen. If I then hit the back button I go back to the home. I can now press this shortcut and it will start the Toggle activity and not change the screen. Before I added: shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); It would open up the TimeClock activity every time. Now it is just the first time. But I want it to never show anything on the screen when the Toggle shortcut is pressed. Does anyone have any idea of how to get rid of that?

• Android SMS API

  - by Schildmeijer

  I know that the SMS content provider is not part of the public API (at least not documented), but if I understand correctly it's still possible to use many of the SMS features as long as you know how to use the API(?). E.g it's pretty straightforward to insert an SMS into your inbox: ContentValues values = new ContentValues(); values.put("address", "+457014921911"); contentResolver.insert(Uri.parse("content://sms"), values); Unfortunately this does not trigger the standard "new-SMS-in-your-inbox" notification. Is it possible to trigger this manually? Edit: AFAIK the "standard mail application (Messaging)" in Android is listening for incoming SMSes using the android.permission.RECEIVE_SMS permission. And then, when a new SMS has arrived, a status bar notification is inserted with a "special" notification id. So one solution to my problem (stated above) could be to find, and send the correct broadcast intent; something like "NEW SMS HAS ARRIVED"-intent. Edit: Downloaded a third party messaging application (chompsms) from Android market. This application satisfies my needs better. When i execute the code above the chompsms notice the new sms and shows the "standard status bar notification". So I would say that the standard Android Messaging application is not detecting sms properly? Or am I wrong?

• Custom Database integration with MOSS 2007

  - by Bob

  Hopefully someone has been down this road before and can offer some sound advice as far as which direction I should take. I am currently involved in a project in which we will be utilizing a custom database to store data extracted from excel files based on pre-established templates (to maintain consistency). We currently have a process (written in C#.Net 2008) that can extract the necessary data from the spreadsheets and import it into our custom database. What I am primarily interested in is figuring out the best method for integrating that process with our portal. What I would like to do is let SharePoint keep track of the metadata about the spreadsheet itself and let the custom database keep track of the data contained within the spreadsheet. So, one thing I need is a way to link spreadsheets from SharePoint to the custom database and vice versa. As these spreadsheets will be updated periodically, I need tried and true way of ensuring that the data remains synchronized between SharePoint and the custom database. I am also interested in finding out how to use the data from the custom database to create reports within the SharePoint portal. Any and all information will be greatly appreciated.

  Video tags like below plays fine with iPhone, but not Android: <video id="video" width="320" height="240" poster="video/placeholder.jpg" autobuffer controls> <source src="pr6.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'> <source src="pr6.ogv" type='video/ogg; codecs="theora, vorbis"'> </video> With the above code, Android can't even click the clip. It would just see the poster image. Video tag like below however works with Android: <video src="vpr6.mp4" poster="video/placeholder.jpg" onclick="this.play();"/> However, I still need to multiple sources capability (for Firefox ogv support…). Below code does not work (nor do they work if I stick the javascript into the source tags): <video id="video" width="320" height="240" autobuffer controls onclick="this.play();"> <source src="pr6.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'> <source src="pr6.ogv" type='video/ogg; codecs="theora, vorbis"'> </video> With above code, the clip is clickable in Android, but still does nothing.

• Serialization Performance and Google Android

  - by Jomanscool2

  I'm looking for advice to speed up serialization performance, specifically when using the Google Android. For a project I am working on, I am trying to relay a couple hundred objects from a server to the Android app, and am going through various stages to get the performance I need. First I tried a terrible XML parser that I hacked together using Scanner specifically for this project, and that caused unbelievably slow performance when loading the objects (~5 minutes for a 300KB file). I then moved away from that and made my classes implement Serializable and wrote the ArrayList of objects I had to a file. Reading that file into the objects the Android, with the file already downloaded mind you, was taking ~15-30 seconds for the ~100KB serialized file. I still find this completely unacceptable for an Android app, as my app requires loading the data when starting the application. I have read briefly about Externalizable and how it can increase performance, but I am not sure as to how one implements it with nested classes. Right now, I am trying to store an ArrayList of the following class, with the nested classes below it. public class MealMenu implements Serializable{ private String commonsName; private long startMillis, endMillis, modMillis; private ArrayList<Venue> venues; private String mealName; } And the Venue class: public class Venue implements Serializable{ private String name; private ArrayList<FoodItem> foodItems; } And the FoodItem class: public class FoodItem implements Serializable{ private String name; private boolean vegan; private boolean vegetarian; } IF Externalizable is the way to go to increase performance, is there any information as to how java calls the methods in the objects when you try to write it out? I am not sure if I need to implement it in the parent class, nor how I would go about serializing the nested objects within each object.

• How does it affect me as a developer/engineer/company that Android is open source

  - by danke

  I understand the concept of open source, but I just realized now that I understand it from only one view: when I open source my own code. I don't really understand what benefit I'm getting from receiving the same thing. As a regular developer (like the majority of us here), I did not spend the past 4 years of my life working on "developing" the android. So even though I'm a developer, I'm at the end of the developers chain when it comes to the Android (like most of us). I'm really more of an end user. So my interest in Android isn't really to dedicate all my time to it or work on improving its kernel or anything overly ambitious. So with that clear, as a developer considering developing for the Android, how does it really benefit me that it's open source? What's the added benefit that I'm missing? Can other developers share some concrete ways that its open source status actually affects us as developers. Basically I'm trying to understand how we, at this developer level, can make sense of the fact that it's open source, or is its open source status just hype for us at our end developer level. Thanks

  I'm trying to pass a bundle of two values from a started class to my landnav app, but according to the debug nothing is getting passed, does anyone have any ideas why? package edu.elon.cs.mobile; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; public class PointEntry extends Activity{ private Button calc; private EditText longi; private EditText lati; private double longid; private double latd; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.pointentry); calc = (Button) findViewById(R.id.coorCalcButton); calc.setOnClickListener(landNavButtonListener); longi = (EditText) findViewById(R.id.longitudeedit); lati = (EditText) findViewById(R.id.latitudeedit); } private void startLandNav() { Intent intent = new Intent(this, LandNav.class); startActivityForResult(intent, 0); } private OnClickListener landNavButtonListener = new OnClickListener() { @Override public void onClick(View arg0) { Bundle bundle = new Bundle(); bundle.putDouble("longKey", longid); bundle.putDouble("latKey", latd); longid = Double.parseDouble(longi.getText().toString()); latd = Double.parseDouble(lati.getText().toString()); startLandNav(); } }; } This is the class that is suppose to take the second point package edu.elon.cs.mobile; import com.google.android.maps.GeoPoint; import com.google.android.maps.MapActivity; import com.google.android.maps.MapController; import com.google.android.maps.MapView; import com.google.android.maps.MyLocationOverlay; import com.google.android.maps.Overlay; import android.content.Context; import android.graphics.drawable.Drawable; import android.hardware.Sensor; import android.hardware.SensorEvent; import android.hardware.SensorEventListener; import android.hardware.SensorManager; import android.location.Location; import android.location.LocationManager; import android.os.Bundle; import android.util.Log; import android.widget.EditText; import android.widget.TextView; public class LandNav extends MapActivity{ private MapView map; private MapController mc; private GeoPoint myPos; private SensorManager sensorMgr; private TextView azimuthView; private double longitudeFinal; private double latitudeFinal; double startTime; double newTime; double elapseTime; private MyLocationOverlay me; private Drawable marker; private GeoPoint finalPos; private SitesOverlay myOverlays; public LandNav(){ startTime = System.currentTimeMillis(); } public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.landnav); Bundle bundle = this.getIntent().getExtras(); if(bundle != null){ longitudeFinal = bundle.getDouble("longKey"); latitudeFinal = bundle.getDouble("latKey"); } azimuthView = (TextView) findViewById(R.id.azimuthView); map = (MapView) findViewById(R.id.map); mc = map.getController(); sensorMgr = (SensorManager) getSystemService(Context.SENSOR_SERVICE); LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE); Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER); int longitude = (int)(location.getLongitude() * 1E6); int latitude = (int)(location.getLatitude() * 1E6); finalPos = new GeoPoint((int)(latitudeFinal*1E6), (int)(longitudeFinal*1E6)); myPos = new GeoPoint(latitude, longitude); map.setSatellite(true); map.setBuiltInZoomControls(true); mc.setZoom(16); mc.setCenter(myPos); marker = getResources().getDrawable(R.drawable.greenmarker); marker.setBounds(0,0, marker.getIntrinsicWidth(), marker.getIntrinsicHeight()); me = new MyLocationOverlay(this, map); myOverlays = new SitesOverlay(marker, myPos, finalPos); map.getOverlays().add(myOverlays); } @Override protected boolean isRouteDisplayed() { return false; } @Override protected void onResume() { super.onResume(); sensorMgr.registerListener(sensorListener, sensorMgr.getDefaultSensor(Sensor.TYPE_ORIENTATION), SensorManager.SENSOR_DELAY_UI); me.enableCompass(); me.enableMyLocation(); //me.onLocationChanged(location) } protected void onPause(){ super.onPause(); me.disableCompass(); me.disableMyLocation(); } @Override protected void onStop() { super.onStop(); sensorMgr.unregisterListener(sensorListener); } private SensorEventListener sensorListener = new SensorEventListener() { @Override public void onAccuracyChanged(Sensor arg0, int arg1) { // TODO Auto-generated method stub } private boolean reset = true; @Override public void onSensorChanged(SensorEvent event) { newTime = System.currentTimeMillis(); elapseTime = newTime - startTime; if (event.sensor.getType() == Sensor.TYPE_ORIENTATION && elapseTime > 400) { azimuthView.setText(Integer.toString((int) event.values[0])); startTime = newTime; } } }; }
