GTS 中 测试case armeabi-v7a GtsPlacementTestCases 的时候会出现下面的异常，本文总结一下。
com.google.android.placement.gts.CoreGmsAppsPrivappPermissionsTest#testCoreGmsAppsPermissionsWhitelisted
本文主要分析第 1 个case，第 2 个case详情看：GTS 中 testNumberOfHeadedApplications fail 详解
这个case 本来应该是测试Privileged permission 的白名单，但是其中也出现了其他的异常。
来看下log：

@Test
public 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<String> 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<String> 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package，那这里的pkgName 是怎么来的呢？详细看getCoreGmsPackages()：
private List<String> 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-values，如果是Automotive 设备应该获取core_gas_packages，如果不是该设备，应该获取general_core_gms_packages，来看下这两个key-values：
<entry key="cn_core_gms_packages">
<value>com.google.android.gms</value>
<value>com.google.android.webview</value>
<value>com.google.android.configupdater</value>
<value>com.google.android.syncadapters.contacts</value>
<value>com.google.android.backuptransport</value>
<value>com.google.android.onetimeinitializer</value>
<value>com.google.android.partnersetup</value>
<value>com.google.android.gsf</value>
<value>com.android.vending</value>
</entry>
<entry key="general_core_gms_packages">
<value>com.android.chrome</value>
<value>com.android.providers.partnerbookmarks</value>
<value>com.google.android.apps.docs</value>
<value>com.google.android.apps.maps</value>
<value>com.google.android.backuptransport</value>
<value>com.google.android.configupdater</value>
<value>com.google.android.feedback</value>
<value>com.google.android.gm</value>
<value>com.google.android.gms</value>
<value>com.google.android.googlequicksearchbox</value>
<value>com.google.android.gsf</value>
<value>com.google.android.music</value>
<value>com.google.android.onetimeinitializer</value>
<value>com.google.android.partnersetup</value>
<value>com.google.android.setupwizard</value>
<value>com.google.android.syncadapters.contacts</value>
<value>com.google.android.tts</value>
<value>com.google.android.videos</value>
<value>com.google.android.youtube</value>
</entry>这里显然获取的是general_core_gms_packages（有没有发现这里有一个bug，code 中是core_gas_packages，实际上配置文件中是cn_core_gms_packages，显然code 是写错了，所以google 的bug 也不少啊）。而最终原因应该是这里动态添加的package name ，并不是安装到系统中的。
结合这里的log 看，应该是包 com.google.android.apps.docs 并没有安装。
结论：
出现这个case 一般是Privileged permission 的问题，也有例外，需要结合dynamic 文件分析，是否是本地或是google 自身的问题。这里主要是com.google.android.apps.docs 没有安装，需要确认GMS 包里面是否存在。
更新下，google 后来已经豁免：
