Answer 1

遗憾的是，您无法阻止人们在模拟器中安装，但如果您安装了Google许可证 ，则会确保它不会在未经许可的设备上运行。

Answer 2

There's one way how to handle it. Just check device id (IMEI code). For emulator it's always null , so you can define either someone tries to launch it in real device or in emulator.

    TelephonyManager tm=(TelephonyManager )activity.getSystemService(Context.TELEPHONY_SERVICE);
    if(tm==null || !this.hasTelephony())
    {
        Log.v(TAG, "Can't get telephony service. Forcing shut down!");
        return false;
    }
    String deviceId=tm.getDeviceId();
    if(deviceId==null || deviceId.length() < 2)
    {
        Log.v(TAG, "Looks like emulator - bail out!");
        Toast.makeText(activity, "This special version not intended to run in this device!", 5000).show();
        return false;
    }
