How to display alert diaolog(popup) from backgroung running service?
I am having a background Service
which is not binded to any of the application(or Activity). It's monitoring incoming messages, and on receiving message, I have to show one dialog popup. I have t开发者_运维百科ried defining one method which is for showing alert dialog, but it gives exception as "Can't create handler inside thread that has not called Looper.prepare()"
I really don't have any idea regarding how to solve this problem. I have searched many post like this over here but not getting how to resolve this one. Help highly appreciated. Thanks.
Create a Handler seperately like this.
private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
//Call you method in This one...
displayDialog(); or whatever method name is
}
};
Now where you are calling the displayDialog() method or what ever named dialog. replace the following code.
handler.sendEmptyMessage(0);
2nd Posible Solution is :
put your method calling code inside the following:
runOnUiThread(new Runnable(){
public void run(){
//Call the method here
}
});
Hope this helps
Thanks sHaH
