来自模拟器《Battery》: 电源永远是交流充电器。 温度总是0。

您可以使用Build。HOST用来记录主机值，不同的模拟器有不同的主机值。

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。

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;
    }
}

谷歌在Flutter的device-info插件中使用以下代码来确定该设备是否是模拟器:

private boolean isEmulator() {
    return (Build.BRAND.startsWith("generic") && Build.DEVICE.startsWith("generic"))
        || Build.FINGERPRINT.startsWith("generic")
        || Build.FINGERPRINT.startsWith("unknown")
        || Build.HARDWARE.contains("goldfish")
        || Build.HARDWARE.contains("ranchu")
        || Build.MODEL.contains("google_sdk")
        || Build.MODEL.contains("Emulator")
        || Build.MODEL.contains("Android SDK built for x86")
        || Build.MANUFACTURER.contains("Genymotion")
        || Build.PRODUCT.contains("sdk_google")
        || Build.PRODUCT.contains("google_sdk")
        || Build.PRODUCT.contains("sdk")
        || Build.PRODUCT.contains("sdk_x86")
        || Build.PRODUCT.contains("sdk_gphone64_arm64")
        || Build.PRODUCT.contains("vbox86p")
        || Build.PRODUCT.contains("emulator")
        || Build.PRODUCT.contains("simulator");
}

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);
}

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