Apps Using processing-core library with alarmmanager

[Richardy]

Hi,
I am trying to get some some processing code via the processing-core library to to be implemented from the broadcast receiver in some alarm manager code in Android Studio.

I started by creating a simple alarm manger App that fires an alarm every minute (user settable) and this works fine. I then created an App that makes use of the processing-core library (imported the library as a jar dependency into android studio) and this also works.

The next step was to amalgamate the above and create an App that fires a sketch class from the broadcast receiver that includes some simple processing code but i am unsure as to how i do this.

My attempt at doing this is shown below. The only class that creates errors is the broadcast receiver class which creates errors related to frameLayout, setContentView and Fragment.setView.

Any help with this is much appreciated.

Cheers.

All classes and XML file are shown below:

MainActivity.java

public class MainActivity extends AppCompatActivity {
    private PApplet sketch;
    Button start;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        start= findViewById(R.id.button);

        start.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                startAlert();
            }
        });
    }

    public void startAlert(){
        EditText text = findViewById(R.id.time);
        int i = Integer.parseInt(text.getText().toString());
        Intent intent = new Intent(this, MyBroadcastReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(
                this.getApplicationContext(), 234324243, intent, 0);
        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
        alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()
                + (i * 1000), pendingIntent);
        Toast.makeText(this, "Alarm set in " + i + " seconds",Toast.LENGTH_LONG).show();
    }
}
