问题
In Android Studio, when I press play button to install and run the app on the Android Emulator, after about 5-10 seconds, I get a message on the bottom of the screen saying "Install successful" but the app doesn't actually run on the emulator, I have to press the play button again. This is quite frustrating because I have worked on projects where I just press play once and it installs and runs at the same time.
I tried searching this forum but couldn't find an answer. Does anybody else experience this and how do you fix it?
