We tried everything to finish a particular activity but failed to do so. The Code runs without any error or warning just cant finish the activity. We tried every solutions in stackoverflow along with other forums. Need a solution with explanation.
我们想尽一切办法完成一项特定的活动，但未能如愿。代码运行没有任何错误或警告，只是无法完成活动。我们与其他论坛一起尝试了 stackoverflow 中的所有解决方案。需要一个带有解释的解决方案。

Try to create a method on your Activitythat will call finish(). And then, call this method from within your onResponse().
尝试在您的设备上创建一个Activity将调用的方法finish()。然后，从您的onResponse().
Something like:
就像是：
private void killActivity() {
finish();
}
And then, call it here:
然后，在这里调用它：
if(Boolean.parseBoolean(Flag)) {
Intent intent=new Intent(PhoneVerificationActivity.this,ConfirmSms.class);
intent.putExtra("PhoneNumber", Phone);
startActivity(intent);
killActivity(); // Here.
}

Check the following in your code
在您的代码中检查以下内容
1.Are you extends Activity correctly?
1.你是否正确地扩展了Activity？
Public class YourActivity extends Activity{
}
2.if you extends activity correctly, Finish() will work properly.
2.如果您正确扩展活动，Finish() 将正常工作。
YourActivity.this.finish();
3.if you use Dialogs, you should dismiss the Dialog before finish the activity
3.如果你使用对话框，你应该在完成活动之前关闭对话框
Dialog.dismiss();
Hope may be its helpful.
希望可能会有所帮助。
Happy Coding :)
快乐编码:)

If you are transferring big data in intent result then it may not finish activity. e.g when i am putting byte array on image of big size, finish is not working, when i change image size same code works.
如果您在意图结果中传输大数据，则它可能无法完成活动。例如，当我将字节数组放在大尺寸的图像上时，完成不起作用，当我更改图像尺寸时，相同的代码有效。
