How can I trigger a BroadcastReceiver on Android 11 using adb?


I have two receivers I want to trigger manually and I can't seem to do it. These are the commands I'm using:

adb -s deviceid shell am broadcast -a action android.intent.action.PHONE_STATE

or

adb -s deviceid shell am broadcast -a action android.intent.action.MEDIA_BUTTON

I've tried adding -p mypackage or -n mypackage/myreceiver and they never get triggered. I also don't see anything on logcat. Adb returns result=0, not sure what that means.


Solution

  • Try this.

    adb -s deviceid shell am broadcast -a android.intent.action.VIEW -n com.mypackage.broadcast/com.mypackage.broadcast.Broadcaster
    

    Example of broadcast class.

    import android.content.*;
    import android.widget.*;
    
    public final class Broadcaster extends BroadcastReceiver
    {   
        @Override
        public final void onReceive(final Context context, final Intent intent) {
            intent.setClass(context, Starter.class);
            //Note: without this flag android will throw a runtime exception.
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            
            try {
                context.startActivity(intent);
            } catch (final Exception e) {
                Toast.makeText(context, e.getMessage(), 1) .show();
                forceStop();
            }
            forceStop();
        }
        
        private final void forceStop() {
            clearAbortBroadcast();
            //throw new RuntimeException();
            System.exit(0);
        }
        
    }
    

    Starter.java //Class that you want to start

    public final class Starter extends Activity {
         @Override
          protected final void onCreate(final Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                //Do something
          }
    }
    

    And dont forget to put this inside your manifest.

     <application
    android:noHistory="true"
    android:launchMode="singleInstance"
    android:excludeFromRecents="true"
    android:exported="true"
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.Translucent.NoTitleBar">
            
    <!-- RECEIVER -->
        <receiver 
            android:name="com.mypackage.broadcast.Broadcaster"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <action android:name="android.intent.action.SEND" />
                <data android:mimeType="*/*" />
                </intent-filter>
        </receiver>
    ...
