Android Studio Record a WAV file every 30 seconds (JAVA)

I'm trying to create an app that will record a WAV file every 30 seconds before comparing it to a saved WAV file and then deleting it. I want this to happen continuously, and stop manually.

I've edited code that records a single WAV file with a timer implementation:

Timer t = new timer ();



@Override


protected void onCreate (bundle savedInstanceState) {
String name = getIntent (). GetExtras (). GetString ("Name");
String email = getIntent (). GetExtras (). GetString ("email");
String phone = getIntent (). GetExtras (). GetString ("phone");

super.onCreate (savedInstanceState);

setContentView (R.layout.activity_main7);







// No inspection ConstantConditions

findViewById (R.id.btnStart) .setOnClickListener (new View.OnClickListener () {

@Override

public void onClick (View v) {

if (ContextCompat.checkSelfPermission (Main7Activity.this, Manifest.permission.RECORD_AUDIO)

! = PackageManager.PERMISSION_GRANTED) {

// Ask for permission

ActivityCompat.requestPermissions (Main7Activity.this,

new string[] {Manifest.permission.RECORD_AUDIO}

PERMISSION_RECORD_AUDIO);

Return;

}

// authorization already exists

launchTask ();

}

});




// No inspection ConstantConditions

findViewById (R.id.btnStop) .setOnClickListener (new View.OnClickListener () {

@Override

public void onClick (View v) {

if (! recordTask.isCancelled () && recordTask.getStatus () == AsyncTask.Status.RUNNING) {

recordTask.cancel (false);

} else {

Toast.makeText (Main7Activity.this, "Task is not running.", Toast.LENGTH_SHORT) .show ();

}

}

});


// restore the previous task or create a new one if needed

recordTask = (RecordWaveTask) getLastCustomNonConfigurationInstance ();

if (recordTask == null) {

recordTask = new RecordWaveTask (this);

} else {

recordTask.setContext (this);

}




}



@Override

public void onRequestPermissionsResult (int requestCode, @NonNull String[] Permissions, @NonNull int[] grantResults) {

switch (requestCode) {

case PERMISSION_RECORD_AUDIO:

if (grantResults.length> 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

// Permission granted

launchTask ();

} else {

// Access Denied

Toast.makeText (this, " uD83D  uDE41", Toast.LENGTH_SHORT) .show ();

}

break;

}

}




private void launchTask () {

switch (recordTask.getStatus ()) {

case RUNNING:

Toast.makeText (this, "Task is already running ...", Toast.LENGTH_SHORT) .show ();

Return;



Case FINISHED:

recordTask = new RecordWaveTask (this);

break;

case pending:

if (recordTask.isCancelled ()) {

recordTask = new RecordWaveTask (this);

}

}


wavFile = new file (getFilesDir (), "monitor.wav");
name = wavFile.getName ();
fileName = System.currentTimeMillis () / 1000 + ".wav";

t.scheduleAtFixedRate (new TimerTask () {
@Override
public void run () {

recordTask.execute (wavFile);
}
}, 0, 30000);


}




@Override

This caused the app to crash every time.

see logat below:

The main part of the code, which the Logcat also reproduces, is the following:

    t.scheduleAtFixedRate (new TimerTask () {
@Override
public void run () {
launchTask ();

recordTask.execute (wavFile);
}
}, 0, 30000);

I would be very happy to receive advice or feedback on how to proceed.
