应用能否在 android 模拟器中识别它们运行？

Question

我想知道 android 应用程序如何在 android 模拟器中发现它是运行。除此之外，如果设备是刚启动的，则没有安装用户文件和其他应用程序。是否有关于该主题的任何资源？

提前致谢

可以了解您的应用运行所在设备的详细信息。从这些详细信息中，您可以确定该设备是模拟器还是物理设备。请通过下面的 link 查看指纹、制造商、设备、型号、产品。

例如：在您的初始屏幕中，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);
