无论使用哪种代码来执行模拟器检测，我会强烈建议编写单元测试，以覆盖所有的Build.FINGERPRINT，Build.HARDWARE而Build.MANUFACTURER你是取决于值。以下是一些示例测试：
@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();
}
...这是我们的代码（为简洁起见，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;
}
}
android.os.Build。
