应用程序能否识别出它们在android模拟器中运行？

Question

我想知道一个android应用如何发现它正在android模拟器中运行。除此之外，如果设备重新启动，则不会安装用户文件和其他应用程序。是否有关于该主题的资源？

提前感谢

例如：在启动画面中，如果您将下面的代码放在下面，那么在Logcat中，您应该会看到类似以下的日志

`Log.e(TAG, "------------");
 Log.e(TAG, "Device Values");
 Log.e(TAG, "Fingerprint: " + Build.FINGERPRINT);
 Log.e(TAG, "Brand: " + Build.BRAND);
 Log.e(TAG, "Device: " + Build.DEVICE);
 Log.e(TAG, "Manufacturer: " + Build.MANUFACTURER);
 Log.e(TAG, "Model: " + Build.MODEL);
 Log.e(TAG, "Product: " + Build.PRODUCT);

[如果您看到上述日志，您将看到对于Emulator，设备值将为Generic，而对于物理设备，它将显示设备型号的名称。
