android 活动在调用完成（）后继续运行

Question

In splash activity I want to exit app when calling onStop() ( I want to stop app if user clicks home button , Close screen or press backbutton )

Unfortunately calling finish() didn't help , even after exiting app the splash activity continue working and even starts the next activity

I would like to mention that there is an asynctask class inside splash.activity and there is also another class jsonfetch called in splash.activity ( fetch data from server and open next activity after ) I think this one doesnt stop because when exiting app it opens the next activity after few secondes

Answer 1

I suspect you are navigating to your MainActivity from you SplashActivity.

Try adding a global variable shouldNavigate to your SplashActivity and change it to false if onStop() is called;

private boolean shouldNavigate = true

    @Override
    protected void onStop() {
        shouldNavigate = false;
        super.onStop();   
        finish();
    }

And then do a check when navigating to your MainActivity:

if (shouldNavigate){
     // navigate to MainActivity
}

Answer 2

If you are using countdowntimer in splash activity, then please stop that in onStop() . It will help you.

Answer 3

After several tests I found that System.exit(0); fixed the problem for me , I hope this solution helps anyone that has the same issue

try this

System.exit(0);
try{ 
    finish();
    //code  press backbutton 
    }catch(Exception  e){
}
finally{  //inside  
    System.exit(0);
}
