This is code :

protected void runServices() {
if (LocationUtil.isLocationEnabled(getBaseContext())) {
if (checkPermission()) {
runLocationService();
}
} else {
AlertDialog.Builder dialog = new AlertDialog.Builder(this);
dialog.setMessage(getResources().getString(R.string.location_settings_disabled));
dialog.setPositiveButton(getString(R.string.go_to_location_settings), new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface paramDialogInterface, int paramInt) {
App.getBus().post(new PageNavigateEvent(Const.APP_SETTINGS_LOCATION));
}
});
dialog.setNegativeButton(getResources().getString(R.string.cancel), new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface paramDialogInterface, int paramInt) {
finish();
}
});
dialog.show();
}
runTrackerService();
runConfigService();
}


and this line cause errors :

dialog.show();

Add Current ActivityName.this instead of this.

 AlertDialog.Builder dialog = new AlertDialog.Builder(YourCurrentActivityName.this);
