Hi all,
I am receiving Text messages from another application sent through
broadcast intent. I am displaying these messages to my application's
GUI.
In my application I had defined <broadcast receiver> in my
manifest.xml
------------------------------------------------------------------------------
<receiver android:name=".HHBroadcastReceiver">
<intent-filter>
<action android:name="android.demo.test"/>
</intent-filter>
</receiver>
-------------------------------------------------------------------------------------
and also define the logic in the Broadcast receiver class
-------------------------------------------------------------------------------------------
public class HHBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
//TODO: React to the Intent received.
String msg_receive = intent.getStringExtra("message1");
AssetTest.hh_text.append("\n\n"+msg_receive);
}
}
---------------------------------------------------------------------------------------------
but I am getting following error,
09-04 10:49:04.275: ERROR/AndroidRuntime(912):
