Android：在某些设备上按“主页”按钮后，应用程序将无法回家

Question

I am developing an Android app. When the app is running in the emulator or on my Moto 4G or the Google Pixel and I press the home button, I am going home (as expected).

However, when I run the app on an Acer E380 and I press the home button, nothing happens, although other apps on the same mobile phone don't have this issue.

The emulator, Moto 4G and Acer E380 are running on Android 4.4.2.

I have no code that tries to detect a home button press.

What could be the problem here?

Answer 1

have you using below code ?

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {     

    if(keyCode == KeyEvent.KEYCODE_HOME)
    {
       //The Code Want to Perform. 
    }
});
