Mixing
null pointer exception on getStringExtra
-1
I have an intent service that sends an intent, like this:
Intent result = new Intent("TEST_RESULT");
result.putExtra("MODE", "testing");
sendBroadcast(result);
in another application, the intent gets captured by a broadcast receiver, like this:
receiver registration:
IntentFilter testResultIntentFilter = new IntentFilter("TEST_RESULT");
TestResultReceiver receiver = new TestResultReceiver();
this.registerReceiver(receiver,testResultIntentFilter);
onReceive method in the receiver:
@Override
public void onReceive(Context context, Intent intent) {
String message = intent.getStringExtra("MODE");
Toast.makeText(context, message, Toast.LENGTH_SHORT).show();
}
this code fails on the getStringExtra call with null pointer exception, it's as if the putExtra method is ignored. I tried everything but nothing works.

Intent result = new Intentand thenintent.putStri. Is it a typo or you have multiple intents?

Please provide the complete stack trace. There's really no way that thegetStringExtra()line is throwing an NPE. ThatIntentcannot be null, andgetStringExtra()will return null if there is noStringextra with that key, but it won't throw an NPE there.
