Follow-up code not executing after checking permissions

Question

The code I have written should check the permissions in the OnStart method and regardless of the outcome of whether the user gives access, the same two pieces of code should execute:

1. Starting my service
2. Auto-login the user if they have provided credentials before

If I retype my credentials and turn the app on and off then on again - then for around 2-5 minutes it will automatically log me in. If I have the app off for longer than that, the autologin will not work.

OnStart:

@Override
protected void onStart() {
    super.onStart();

    List<String> permissions = new ArrayList<>();
    permissions.add(Manifest.permission.ACCESS_FINE_LOCATION);
    permissions.add(Manifest.permission.ACTIVITY_RECOGNITION);
    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.S)
        permissions.add(Manifest.permission.SCHEDULE_EXACT_ALARM);

    checkPermission(permissions.toArray(new String[0]), INITIAL_REQUESTS_CODE);
}

checkPermission Function:

  public void checkPermission(String[] permissions, int requestCode) {
    // Checking if permission is not granted
    boolean ungrantedPermissions = false;
    for (String permission : permissions) {
        if (ContextCompat.checkSelfPermission(this, permission) == PackageManager.PERMISSION_DENIED) {
            ungrantedPermissions = true;
            break;
        }
    }
    if (ungrantedPermissions)
        ActivityCompat.requestPermissions(this, permissions, requestCode);
    else{
        startStepCounterService();
        attemptLoginWithSavedCredentials();
    }
}

onRequestPermissionResult:

 @Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode,
            permissions,
            grantResults);

    startStepCounterService();
    attemptLoginWithSavedCredentials();
}

startStepCounterService Function:

  private void startStepCounterService() {
    if(!isMyServiceRunning(StepCounterService.class))
    {
        Intent newIntent = new Intent(this, StepCounterService.class);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            startForegroundService(newIntent);
        } else {
            startService(newIntent);
        }
    }
}

attemptLoginWithSavedCredentials Function:

    private void attemptLoginWithSavedCredentials() {
    String savedUsername = SaveSharedPreference.getUserName(this);
    String savedPassword = SaveSharedPreference.getUserPassword(this);
    if(!savedUsername.isEmpty() && !savedPassword.isEmpty())
    {
        LoadingExtensions.showLoadingIcon(loadingIndicator, rootView);
        loginManager.login(savedUsername, savedPassword);
    }
}
