在模拟器的文件系统中放入一个文件;由于该文件不会存在于真正的设备上，这应该是稳定的，可靠的，容易修复当它崩溃。

以下两个都被设置为“google_sdk”:

Build.PRODUCT
Build.MODEL

因此，使用下列任意一行就足够了。

"google_sdk".equals(Build.MODEL)

or

"google_sdk".equals(Build.PRODUCT)

这个方法对我有用

    public static boolean isRunningOnEmulator(String fingerprint, String hardware, String manufacturer) {
    boolean isEmulatorFingerprint = fingerprint.endsWith("test-keys");
    boolean isHardware = hardware.toLowerCase().contains("intel") || hardware.toLowerCase().contains("vbox");
    boolean isEmulatorManufacturer = manufacturer.equals("Genymotion")
            || manufacturer.equals("unknown");

    if (isHardware || isEmulatorFingerprint && isEmulatorManufacturer) {
        return true;
    } else {
        return false;
    }
}

以下是我的解决方案(它只适用于在调试机器上运行web服务器): 我已经创建了一个后台任务，当应用程序启动时启动。它查找http://10.0.2.2，如果它存在，它将全局参数(IsDebug)更改为true。这是一种无声的方式来找出你在哪里跑步。

public class CheckDebugModeTask extends AsyncTask<String, Void, String> {
public static boolean IsDebug = false;

public CheckDebugModeTask()
{

}

@Override
protected String doInBackground(String... params) {     
  try {
    HttpParams httpParameters = new BasicHttpParams();
    int timeoutConnection = 1000;
    HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
    int timeoutSocket = 2000;
    HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

    String url2 = "http://10.0.2.2";        
          HttpGet httpGet = new HttpGet(url2);
    DefaultHttpClient client = new DefaultHttpClient(httpParameters);

    HttpResponse response2 = client.execute(httpGet);
    if (response2 == null || response2.getEntity() == null || response2.getEntity().getContent() == null)
    return "";

    return "Debug";

} catch (Exception e) {
    return "";
}
}

@Override
protected void onPostExecute (String result)
{       
if (result == "Debug")
{
    CheckDebugModeTask.IsDebug = true;
}
}

从主活动onCreate:

CheckDebugModeTask checkDebugMode = new CheckDebugModeTask();
checkDebugMode.execute("");

这对我来说是有效的，而不是startwith: Build.FINGERPRINT.contains("generic")

Firebase Crashlytics是这样做的:

private static final String GOLDFISH = "goldfish";
private static final String RANCHU = "ranchu";
private static final String SDK = "sdk";
    
public static boolean isEmulator() {
    return Build.PRODUCT.contains(SDK)
        || Build.HARDWARE.contains(GOLDFISH)
        || Build.HARDWARE.contains(RANCHU);
}
