GTS 中testCoreGmsAppsPermissionsWhitelist

GTS 中 测试-v7a s 的时候会出现下面的异常，本文总结一下。

com....gts.#

本文主要分析第 1 个case，第 2 个case详情看：GTS 中 fail 详解

这个case 本来应该是测试 的白名单，但是其中也出现了其他的异常。

来看下log：

07-30 23:29:59 I/ModuleListener: [1/20] com.google.android.placement.gts.CoreGmsAppsPrivappPermissionsTest#testCoreGmsAppsPermissionsWhitelisted fail:

来看下code：

    @Testpublic void testCoreGmsAppsPermissionsWhitelisted() throws Exception {if (ApiLevelUtil.isBefore(26)) {String str = TAG;StringBuilder stringBuilder = new StringBuilder();stringBuilder.append("Skipping test because privileged permissions whitelist was introduced in Android 8.0. Current API Level ");stringBuilder.append(ApiLevelUtil.getApiLevel());Log.i(str, stringBuilder.toString());return;}boolean atLeastP = ApiLevelUtil.isAtLeast((int) true);PackageManager packageManager = BusinessLogicTestCase.getContext().getPackageManager();Set platformPrivilegedPermissions = getPlatformPrivilegedPermissions();for (String pkgName : getCoreGmsPackages()) {int flags = 12288;if (atLeastP) {flags = 12288 | 2097152;}PackageInfo pkg = packageManager.getPackageInfo(pkgName, flags);String str2;StringBuilder stringBuilder2;if (!pkg.applicationInfo.isPrivilegedApp()) {str2 = TAG;stringBuilder2 = new StringBuilder();stringBuilder2.append("Skipping check for non-privileged package ");stringBuilder2.append(pkgName);Log.i(str2, stringBuilder2.toString());} else if (atLeastP || (pkg.applicationInfo.flags & 128) == 0) {Set deniedPrivPermissions = new TreeSet();int i = 0;while (i < pkg.requestedPermissions.length) {String permission = pkg.requestedPermissions[i];if (platformPrivilegedPermissions.contains(permission) && (pkg.requestedPermissionsFlags[i] & 2) == 0) {deniedPrivPermissions.add(permission);}i++;}stringBuilder2 = new StringBuilder();stringBuilder2.append("All privileged permissions should be granted to ");stringBuilder2.append(pkgName);stringBuilder2.append(", but the following permissions were not granted: ");stringBuilder2.append(deniedPrivPermissions);Assert.assertTrue(stringBuilder2.toString(), deniedPrivPermissions.isEmpty());} else {str2 = TAG;stringBuilder2 = new StringBuilder();stringBuilder2.append("Skipping whitelist checks for ");stringBuilder2.append(pkgName);stringBuilder2.append(" - application was updated");Log.w(str2, stringBuilder2.toString());}}}

在code 执行到：

PackageInfo pkg = packageManager.getPackageInfo(pkgName, flags);

系统中并没有这样的，那这里的 是怎么来的呢？详细看()：

    private List getCoreGmsPackages() throws IOException, XmlPullParserException {DynamicConfigDeviceSide dcds = new DynamicConfigDeviceSide("GtsPlacementTestCases");if (isAutomotiveDevice()) {return dcds.getValues("core_gas_packages");}return dcds.getValues("general_core_gms_packages");}

code 可以看出应该是一个配置文件中不同的key-，如果是 设备应该获取，如果不是该设备，应该获取kages，来看下这两个key-：

    com.google.android.gmscom.google.android.webviewcom.google.android.configupdatercom.google.android.syncadapters.contactscom.google.android.backuptransportcom.google.android.onetimeinitializercom.google.android.partnersetupcom.google.android.gsfcom.android.vendingcom.android.chromecom.android.providers.partnerbookmarkscom.google.android.apps.docscom.google.android.apps.mapscom.google.android.backuptransportcom.google.android.configupdatercom.google.android.feedbackcom.google.android.gmcom.google.android.gmscom.google.android.googlequicksearchboxcom.google.android.gsfcom.google.android.musiccom.google.android.onetimeinitializercom.google.android.partnersetupcom.google.android.setupwizardcom.google.android.syncadapters.contactscom.google.android.ttscom.google.android.videoscom.google.android.youtube

这里显然获取的是kages（有没有发现这里有一个bug，code 中是，实际上配置文件中是，显然code 是写错了，所以 的bug 也不少啊）。而最终原因应该是这里动态添加的 name ，并不是安装到系统中的。

结合这里的log 看，应该是包com...apps.docs 并没有安装。

结论：

出现这个case 一般是 的问题，也有例外，需要结合 文件分析，是否是本地或是 自身的问题。这里主要是com...apps.docs 没有安装，需要确认GMS 包里面是否存在。

更新下， 后来已经豁免：
