Intent and string array

Question

I need pass a string array from AlarmReceiver.class to Notify.class but the string is always "null". Now, is a problem about intent within AlarmReceiver?

public class AlarmReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
[...]
Intent notificationIntent = new Intent("com.example.myapp", null, context, Notify.class);
        notificationIntent.putExtra("notify", not1[x]);
        PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

Notify class:

@Override
    public void onCreate(Bundle savedInstanceState){ 
      super.onCreate(savedInstanceState);
Intent notificationIntent = getIntent();
      String[] message = notificationIntent.getStringArrayExtra("notify");
Toast toast6=Toast.makeText(this,""+message,Toast.LENGTH_LONG);
        toast6.show();

You are mixing string array with a plain string. which do you want? — Mattias Isegran Bergander

You are using two different methods...

Here you're are working with one String:

notificationIntent.putExtra("notify", not1[x]); // Pass one String

You should read this "notify" with:

String message = notificationIntent.getStringExtra("notify");

If you want to pass the array of Strings use:

notificationIntent.putExtra("notify", not1); // Pass array of Strings

You should read this with:

String[] message = notificationIntent.getStringArrayExtra("notify");

Do you see the difference?

Or the other way around, putExtra("notify", not1); as it seems the question asks about sending an array. Not that it is used that way so a bit confusing.

Thanks Sam! You're always so gentle! :-)

Sam: what it the best way to cancel notify after click on it?

Sam Over a year ago

You can call NotificationManager#cancel(), using the id that you used in notify().
