我希望我的代码在模拟器上运行时与在设备上运行时略有不同。(例如,使用10.0.2.2代替公共URL在开发服务器上自动运行。)检测Android应用程序何时在模拟器中运行的最佳方法是什么?

无论您使用哪种代码来进行模拟器检测,我都强烈建议编写单元测试来覆盖所有构建。指纹,构建。硬件和构建。您所依赖的制造商值。下面是一些测试示例:

@Test
public void testIsEmulatorGenymotion() throws Exception {
    assertThat(
            DeviceUtils.isRunningOnEmulator(
                    "generic/vbox86p/vbox86p:4.1.1/JRO03S/eng.buildbot.20150217.102902:userdebug/test-keys",
                    "vbox86", "Genymotion")).isTrue();

    assertThat(
            DeviceUtils.isRunningOnEmulator(
                    "generic/vbox86p/vbox86p:5.1/LMY47D/buildbot06092001:userdebug/test-keys", "vbox86",
                    "Genymotion")).isTrue();
}

@Test
public void testIsEmulatorDefaultAndroidEmulator() throws Exception {
    assertThat(
            DeviceUtils.isRunningOnEmulator(
                    "generic_x86/sdk_google_phone_x86/generic_x86:5.0.2/LSY66H/1960483:eng/test-keys", "goldfish",
                    "unknown")).isTrue();

    assertThat(
            DeviceUtils.isRunningOnEmulator(
                    "Android/sdk_google_phone_x86_64/generic_x86_64:6.0/MASTER/2469028:userdebug/test-keys",
                    "ranchu", "unknown")).isTrue();
}

@Test
public void testIsEmulatorRealNexus5() throws Exception {
    assertThat(
            DeviceUtils.isRunningOnEmulator("google/hammerhead/hammerhead:6.0.1/MMB29K/2419427:user/release-keys",
                    "hammerhead", "LGE")).isFalse();
}

...下面是我们的代码(为了简洁起见,删除了调试日志和注释):

public static boolean isRunningOnEmulator() {
    if (sIsRunningEmulator == null) {
        sIsRunningEmulator = isRunningOnEmulator(Build.FINGERPRINT, Build.HARDWARE, Build.MANUFACTURER);
    }

    return sIsRunningEmulator;
}

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

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

上面建议的检查ANDROID_ID的解决方案对我来说很有效,直到我今天更新到Android 2.2发布的最新SDK工具。

因此,我目前切换到以下解决方案,到目前为止,缺点是你需要把PHONE_STATE读取权限(<uses-permission android:name="android.permission. read_phone_state "/>)

private void checkForDebugMode() {
    ISDEBUGMODE = false; //(Secure.getString(getApplicationContext().getContentResolver(), Secure.ANDROID_ID) == null);

    TelephonyManager man = (TelephonyManager) getApplicationContext().getSystemService(Context.TELEPHONY_SERVICE);
    if(man != null){
        String devId = man.getDeviceSoftwareVersion();
        ISDEBUGMODE = (devId == null);
    }
} 
Build.BRAND.startsWith("generic") && Build.DEVICE.startsWith("generic")

如果应用程序在模拟器上运行,这应该返回true。

我们应该注意的是不要检测所有的模拟器,因为只有几个不同的模拟器。这很容易检查。 我们必须确保实际的设备不会被检测为模拟器。

我使用名为“Android设备信息共享”的应用程序来检查这一点。

在这个应用程序上,你可以看到许多设备的各种信息(可能是世界上大多数设备;如果您正在使用的设备不在列表中,它将自动添加)。

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;

} 

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);
}
