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

        createInstances();
        //set up notitle 
        requestWindowFeature(Window.FEATURE_NO_TITLE);  
        //set up full screen

                locationValidationDone=true;
                dialog.dismiss();
                startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));
            }
        });
        alert.show();
    }

解决方案

dialog is used inonstart() please use in oncreate(),

when your back to your actvity it's called the onstart() and onresume(),

please read the activity lifecyclelifecycle

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

    if(!start_dialog)
    {
        start_dialog = true;
        open(getResources().getString(R.string.location_not_enabled));
    }
}
