Answer 1

The following code works for me:

public class BootCompleteReceiver extends BroadcastReceiver {
    public static final String PREFS_NAME = "MyPrefsFile";  

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
            Log.d("boot completed", "boot completed caught");
            Boolean autoRestart = false;
            SharedPreferences sp = context.getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE);
            autoRestart = sp.getBoolean("autoRestart", false);

            if (autoRestart){

                Log.d("boot completed", "auto restart true");

                Intent i = new Intent(context, WelcomeScreen.class);
                i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(i);

            }
        }
    }

}

Answer 2

You have to add the uses-permission android.permission.RECEIVE_BOOT_COMPLETED in your Manifest.

Answer 3

You can use the shared preference to store a Boolean value for isAutoStartEnabled, and check this value in the BroadcastReciver, fire an intent only if it's true.

In your case, the problem is not whether you receive the broadcast but who receives the broadcast. Best of luck..

I hope it helps..

Answer 4

I think from Android 3.1 onwards your BroadcastReceiver which receives BOOT_COMPLETED intent its not going to work. User have to in-wake the application by interacted with it.

So, After booting the device all third party application are lying as a stop.

And for currently your application you can use SharedPreferences for Auto-Start your application..

UPDATE: (Only for Android version below 3.1 for higher version it works but you have to user interaction with your application after boot completed on device)

You need to use a BroadcastReceiver with android.intent.action.BOOT_COMPLETED intent.

Add following to your manifest file:

<receiver android:name="App_Receiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

App_Receiver class implementing BoradcastReciever. Implement the onReceive() method and start your favorite activity from your app.

public void onReceive(Context context, Intent intent) {
    // make sure you receive "BOOT_COMPLETED"
// Here isAutoStartEnabled check sharedPreferences for Auto Start flag
if ( isAutoStartEnabled ) {

    if ((intent.getAction() != null) && (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")))
    {
        // Start the service or activity 
    }
}

Answer 5

final SharedPreferences sharedPreferences = getSharedPreferences("Application", MODE_PRIVATE);
        boolean isAutoStartEnabled = sharedPreferences.getBoolean("isAutoStartEnabled", false);

        if ( isAutoStartEnabled ) {
            startActivity(new Intent());
        } 

I hope this helps you
