Issue
I want to reload my Webview which in in my MainActivity from FirebaseMessagingService when ever a notification arrive and I tap on the notification.
Here is my code so far.
FirebaseMessagingService.java in onMessageReceived method I have
if(MainActivity.isAppRunning){
Delegate.theMainActivity.onNotificationRefresh();
}
Delegate.java
package ###@@##@@;
public class Delegate {
static MainActivity theMainActivity;
}
And in my MainActivity there is this method which i am trying to call
public void onNotificationRefresh() {
webView.loadUrl("www.google.com");
}
right now when every i recieve notification instead of calling reload app crashes.
Error Log
FATAL EXCEPTION: pool-3-thread-1
Process: ###@@##@@, PID: 11092

Solution
Try this way you can use BroadcastReceiver
SAMPLE CODE
public class MyFirebaseMessagingService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Log.e("NOTIFICATION_DATA", remoteMessage.getData() + "");
Intent new_intent = new Intent();
Bundle bundle = new Bundle();// use bundle if you want to pass data
bundle.putString("msgBody", remoteMessage.getData().toString());
new_intent.putExtra("msg", bundle);
new_intent.setAction("ACTION_ACTIVITY");
sendBroadcast(new_intent);
}
}
Than Use in your activity like this
public class MyActivity extends AppCompatActivity {
WebView webView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
}
@Override
protected void onResume() {
super.onResume();
// registering BroadcastReceiver
if (activityReceiver != null) {
IntentFilter intentFilter = new IntentFilter("ACTION_ACTIVITY");
registerReceiver(activityReceiver, intentFilter);
}
}
@Override
protected void onPause() {
super.onPause();
LocalBroadcastManager.getInstance(this).unregisterReceiver(activityReceiver);
}
private BroadcastReceiver activityReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// reload your webview here
webView.loadUrl("https://stackoverflow.com/users/7666442/nilesh-rathod?tab=profile");
}
};
}
