Android BroadcastReceiver can't receive any broadcast events

Question

I have created a BroadcastReceiver to detect SDCard mount and unmount event, however, I am not able to receive any events at all: here's the AndroidManifest.xml:

    <receiver android:enabled="true" android:label="SDCardMountReceiver"
                android:exported="true"
                android:name="xxx.broadcasts.SDCardBroadcastReceiver">
                        <intent-filter>
                                <action
android:name="android.content.Intent.ACTION_MEDIA_MOUNTED"></action>
                               <!-- or  <action
android:name="android.content.Intent.ACTION_MEDIA_UNMOUNTED" />-->

                        </intent-filter>
    </receiver>

And the SDCardMountReceiver class:

public class SDCardBroadcastReceiver extends BroadcastReceiver {
        public SDCardBroadcastReceiver(){
                super();
                System.err.println("constructor");
        }

        public void onReceive(Context context, Intent intent) {
                Log.d("SDCardBroadCastReceiver", "receive "+intent.getAction());
                System.err.println("jonathan receive "+intent.getAction());

        } 

Answer 1

The Intent javadoc specifies a different action:name value. Use "android.intent.action.MEDIA_MOUNTED" instead of "android.content.Intent.ACTION_MEDIA_MOUNTED"

Answer 2

You also need to set the data scheme to "file".

   <intent-filter>
     <action android:name="android.intent.action.MEDIA_MOUNTED" />
     <data android:scheme="file" /> 
   </intent-filter>
