用下面的代码来判断你的应用是否使用了调试键?它没有检测模拟器，但它可能为您的目的工作?

public void onCreate Bundle b ) {
   super.onCreate(savedInstanceState);
   if ( signedWithDebugKey(this,this.getClass()) ) {
     blah blah blah
   }

  blah 
    blah 
      blah

}

static final String DEBUGKEY = 
      "get the debug key from logcat after calling the function below once from the emulator";    


public static boolean signedWithDebugKey(Context context, Class<?> cls) 
{
    boolean result = false;
    try {
        ComponentName comp = new ComponentName(context, cls);
        PackageInfo pinfo = context.getPackageManager().getPackageInfo(comp.getPackageName(),PackageManager.GET_SIGNATURES);
        Signature sigs[] = pinfo.signatures;
        for ( int i = 0; i < sigs.length;i++)
        Log.d(TAG,sigs[i].toCharsString());
        if (DEBUGKEY.equals(sigs[0].toCharsString())) {
            result = true;
            Log.d(TAG,"package has been signed with the debug key");
        } else {
            Log.d(TAG,"package signed with a key other than the debug key");
        }

    } catch (android.content.pm.PackageManager.NameNotFoundException e) {
        return false;
    }

    return result;

}

实际上，ANDROID_ID在2.2上总是等于9774D56D682E549C(根据这个线程+我自己的实验)。

所以，你可以这样检查:

String androidID = ...;
if(androidID == null || androidID.equals("9774D56D682E549C"))
    do stuff;

虽然不是最漂亮的，但也很管用。

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("");

检查答案，当使用LeapDroid, Droid4x或Andy模拟器时，没有一个可以工作，

适用于所有情况的方法如下:

 private static String getSystemProperty(String name) throws Exception {
    Class systemPropertyClazz = Class.forName("android.os.SystemProperties");
    return (String) systemPropertyClazz.getMethod("get", new Class[]{String.class}).invoke(systemPropertyClazz, new Object[]{name});
}

public boolean isEmulator() {
    boolean goldfish = getSystemProperty("ro.hardware").contains("goldfish");
    boolean emu = getSystemProperty("ro.kernel.qemu").length() > 0;
    boolean sdk = getSystemProperty("ro.product.model").equals("sdk");
    return goldfish || emu || sdk;
}

试试这个方法。

在谷歌和Genymotion模拟器上测试。

public Boolean IsVM() {
    String radioVersion = android.os.Build.getRadioVersion();
    return radioVersion == null || radioVersion.isEmpty() || radioVersion.equals("1.0.0.0");
}
