Exception when sending broadcast to ComponentInfo

问题

I have a receiver for Google cloud message, it's registered in AndroidManifest.xml:

    <receiver
        android:name="com.app.android.push.HSPushReceiver"
        android:permission="com.google.android.c2dm.permission.SEND"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
            <action android:name="com.google.android.c2dm.intent.REGISTER" />
            <category android:name="com.app.android" />
        </intent-filter>
    </receiver>

I can receive message when the app is in foreground or killed. However, if I start a IntentService with notification and then swipe the main activity away, then if I send a notification, I got the following crash:

08-29 15:29:37.782 W/BroadcastQueue(  757): Exception when sending broadcast to ComponentInfo{com.app.android/com.app.android.push.HSPushReceiver}

HSNotificationService somehow got crashed. Somehow PushReceiver is dead when activity is swiped away. How to resolve this problem?

回答1:

Found same problem in here. Seems to be an Android bug reported here and here.

I used the workaround in here and it's working for me. Someone said it has side effect though. side effect

The workaround is to start a dummy activity in your foreground service

@Override
public void onTaskRemoved( Intent rootIntent ) {
    Intent intent = new Intent( this, ServiceKeepActivity.class );
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(intent);
}
