Getting bundled extras from a notification reliever intent to a started activity

I have a notification receiver that is being called from my alarm.

The notification receiver bundles the data for a new intent (activity) and starts it like this:

// Create an in intent to go to the new alarm video
Intent repeatingAlarmIntent = new Intent(context,RepeatingAlarmActivity.class);

// Bundle the videoID the alarm has the correct video to open
Bundle alarmExtras = new Bundle();
extras.putString("AlarmVidId", VideoId);
repeatingAlarmIntent.putExtras(alarmExtras);

// Set the flags for the alarm intent
repeatingAlarmIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                    repeatingAlarmIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

// Start the alarm intent
context.startActivity(repeatingAlarmIntent);

In the new activity when I try to retrieve the bundled data it is null, this is how I am attempting to retrieve the bundled data:

public class RepeatingAlarmActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {

    String VideoId;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent intent = getIntent();
        VideoId= intent.getStringExtra("AlarmVidId");

Not sure what I am doing wrong.

Thanks in advance for your help.

Replace all with the following:

Intent repeatingAlarmIntent = new Intent(context,RepeatingAlarmActivity.class);
repeatingAlarmIntent.putExtra("AlarmVidId", VideoId);
repeatingAlarmIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
repeatingAlarmIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(repeatingAlarmIntent);

Your problem is you created a Bundle called alarmExtras however you are putting the extra field in the variable called extra.

There is no need to create Bundle. just add the value directly to the Intent.

Also, you are doing setFlags(). If you need more than one, do addFlags() instead

I worked out a solution.

I am pretty sure it is because of the lifecycle of the notification receiver and the context.

So instead of using the context that was passed when started the receiver I used that context to get the application context.

This method is working but I welcome comments on potential problems with this method as I have never had to solve something like this before.

This is what worked for me:

// Create an in intent to go to the new alarm video
Intent repeatingAlarmIntent = new Intent(context.getApplicationContext(),RepeatingAlarmActivity.class);

// Bundle the videoID the alarm has the correct video to open
Bundle alarmExtras = new Bundle();
extras.putString("AlarmVidId", VideoId);
repeatingAlarmIntent.putExtras(alarmExtras);

// Set the flags for the alarm intent
repeatingAlarmIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                    repeatingAlarmIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

// Start the alarm intent
context.getApplicationContext().startActivity(repeatingAlarmIntent);

Above when creating the intent and starting the intent there is now:

getApplicationContext()

On the activity side were no changes required.

Your extras variable when calling putString does not match the alarmExtras are adding to the Intent.

Bundle alarmExtras = new Bundle();
alarmExtras.putString("AlarmVidId", VideoId);   
repeatingAlarmIntent.putExtras(alarmExtras);
