应用程序可以识别它们在 android 模拟器中运行吗？

Question

我想知道一个 android 应用程序如何发现它正在一个 android 模拟器中运行。除此之外，如果设备刚刚启动，则没有安装用户文件和其他应用程序。有没有关于该主题的资源？

提前致谢

Answer 1

您可以了解运行您的应用的设备的详细信息。从这些细节中您可以确定该设备是模拟器还是物理设备。 请通过以下链接查看指纹、制造商、设备、型号、产品。

https://developer.android.com/reference/android/os/Build.html

例如： 在您的启动画面中，如果您输入以下代码，那么在您的 Logcat 中，您应该会看到如下所示的日志

`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);

如果您看到上面的日志，您会看到对于 Emulator，Device 值将显示为 Generic，而对于物理设备，它将显示设备型号的名称。
