ACTION_MY_PACKAGE_REPLACED not received

问题:

I am using ACTION_MY_PACKAGE_REPLACED to receive when my app is updated or resinstalled. My problem is that the event is never triggered (I tried Eclipse and real device). This is what I do:

Manifest:

Code:

public class MyEventReceiver extends BroadcastReceiver {      @Override public void onReceive(Context context, Intent intent)    {         if ("android.intent.action.ACTION_MY_PACKAGE_REPLACED".equals(intent.getAction()))        {  //Restart services       }    }       } 

This code is simple, in real one I used other events like BOOT_COMPLETED and others, and they work but ACTION_MY_PACKAGE_REPLACED. Thanks.

for some reason, a google developer (named "Dianne Hackborn") thinks it is possible to register to the PACKAGE_REPLACED intent of the current app alone (link here).

however, i can't find any way of doing it correctly, so i've made a compromise: it will use the newest API when available.

Sadly, I can't find out why it can't be debugged, but it does work (you can write to the log if you wish).

here's the code:

manifest:

res/values/version_checks.xml

falsetrue

res/values-v12/version_checks.xml

truefalse

OnUpgradeBroadcastReceiver.java

public class OnUpgradeBroadcastReceiver extends BroadcastReceiver {      @Override     public void onReceive(final Context context, final Intent intent) {         if (VERSION.SDK_INT

The accepted answer doesn't work any more with Android Studio 1.0+ because of manifest merge issues, as seen here. Totally based on android developer's answer, I fixed the issue with the following implementation:

AndroidManifest.xml:

/res/values/resources.xml:

truefalse

/res/values-v12/resources.xml:

falsetrue

UpdateReceiver.java:

import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.util.Log;  public class UpdateReceiver extends BroadcastReceiver {     public static class LegacyUpdateReceiver extends BroadcastReceiver     {         @Override         public void onReceive(Context context, Intent intent)         {             if (intent != null && intent.getData() != null && context.getPackageName().equals(intent.getData().getSchemeSpecificPart()))             {                 onUpdate(context);             }         }     }      @Override     public void onReceive(Context context, Intent intent)     {         onUpdate(context);     }      public static void onUpdate(Context context)     {         Log.d("LOG", "Current app updated");     } }

Getting information from all the users I could solve my situation this way. All of them were right, with little points to notice:

In manifest:

And code:

public class MyEventReceiver extends BroadcastReceiver {          @Override public void onReceive(Context context, Intent intent)     {          if(Intent.ACTION_PACKAGE_REPLACED.equals(intent.getAction()))         {   if(intent.getData().getSchemeSpecificPart().equals(context.getPackageName()))            {  //Restart services.            }        }     }       } 

In my Android release (2.3 Gingerbread) I was not able to use MY_PACKAGE_REPLACED but we solved using PACKAGE_REPLACED (will advise of any app been replaced) but asking if it is ours with:

 if(intent.getData().getSchemeSpecificPart().equals(context.getPackageName()))  {  } 

Thanks to all

I just want to add my own two pence worth here, because I had problems getting this to work and debugging it .. I am using a Lollipop device:

This is the code I used:

To debug it, you need to make sure you have installed the update on your phone, just via Eclipse debug is fine, and opened the app at least one time, then you can simply edit your debug configuration:

eclipse > run > debug configurations > launch action (do nothing) > then F11 like normal 

I confirmed it worked by writing a small file to the SD card

回答5:

Are you trying it on a API>=12 device/emulator? This broadcast will not be sent on prior cases as it is API 12. If you need your app to receive this for Pre-ICS and the old honey comb devices,

try:

if (intent.getAction().equals(Intent.ACTION_PACKAGE_REPLACED)) {   if (!intent.getData().getSchemeSpecificPart()        .equals(context.getPackageName())) {     return;   } }

Simple Manifest working in all version :

You need to add data scheme to the intent filter like below
