Why the Broadcast receiver does not work after killing Android app?

问题

I am using a broadcast receiver in my app to record calls. Everything works fine in Android 5.0 emulator device. If I kill the app, it automatically starts recording calls. But the same app when I installed on my device running Android 6.0, it works until the app is running. When I kill the app the recording is not started, the broadcast receiver is not triggered.

回答1:

String manufacturer = "xiaomi";

 if(manufacturer.equalsIgnoreCase(android.os.Build.MANUFACTURER)) {
        //this will open auto start screen where user can enable 
             permission for your app
                Intent intent = new Intent();
                intent.setComponent(new 
                ComponentName("com.miui.securitycenter", 
               "com.miui.permcenter.autostart.AutoStartManagementActivity"));
                startActivity(intent);
            }

I used this code and now its working fine.
