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：

来看下code：

    @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 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package，那这里的pkgName 是怎么来的呢？详细看getCoreGmsPackages()：

    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-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：

    
        com.google.android.gms
        com.google.android.webview
        com.google.android.configupdater
        com.google.android.syncadapters.contacts
        com.google.android.backuptransport
        com.google.android.onetimeinitializer
        com.google.android.partnersetup
        com.google.android.gsf
        com.android.vending
    
    
        com.android.chrome
        com.android.providers.partnerbookmarks
        com.google.android.apps.docs
        com.google.android.apps.maps
        com.google.android.backuptransport
        com.google.android.configupdater
        com.google.android.feedback
        com.google.android.gm
        com.google.android.gms
        com.google.android.googlequicksearchbox
        com.google.android.gsf
        com.google.android.music
        com.google.android.onetimeinitializer
        com.google.android.partnersetup
        com.google.android.setupwizard
        com.google.android.syncadapters.contacts
        com.google.android.tts
        com.google.android.videos
        com.google.android.youtube
    

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：
