上述失败提示的app都是google的原生应用，例如com.google.android.youtube（YouTube）并且这些app都位于product目录下，我们可以反编译看下此测试项：

可以看到此测试项主要测试product目录下的app是否调用黑名单或者灰名单中的api，也就是非SDK接口管控名单内的api，名单如下：

Android P以后调用非 SDK（包括深灰名单、黑名单）接口的所有应用都将受到影响，Google提供的工具veridex 可以检测app是否调用了这些api,其内含有一个appcompat.sh ,我们可以看GTS也是使用该脚本

1：源码包含此工具，目录在：QSSI.13\art\tools\veridex\appcompat.sh
2：我们可以在QSSI.13 目录下编译此工具：make appcompat
3：我们就可以使用下面的命令行将其扫描内容输出到文件中
./appcompat.sh --dex-file=my_game.apk.apk >> out_put.txt
当然也可以加一个--imprecise参数，加这个参数是为了让输出内容更加详细
./appcompat.sh --dex-file=my_game.apk --imprecise >>  out_put.txt

截图所示为扫描出来的非SDK API，扫描出92个隐藏api,52个反射api,还有一些其他的，例如7个api的最大只支持到q的，当然不是说这些api都不能调用，GTS测试失败的过滤条件为：

也就是下图只有红款内的api会被视为不规范，下面的Linking unsupported 亦或者Reflection unsupported 都可以算正常。

当然还有一个判断：该项是读取GTS配置文件：GtsUnofficialApisUsageTestCases.dynamic内是否配置了额外的api, 如果没有配置，则该方法始终为false,则GTS的此项过滤条件可以不考虑该条件

但是我们发现这些原生的应用肯定是调用了这些api，并且我们没有源码，所以修改不了。也就是按照这个测试工具的判断方法，我们只有一个方法可以测过该项，那就是把这些应用移到别的目录，例如system_ext/app 或者system/app目录下。这个也是可以的，只不过工作量比较大。举例YuTuBe修改如下：

# YouTube
LOCAL_PATH := $(my-dir)
....
#LOCAL_PRIVILEGED_MODULE := true
#phoebe  add for move YuTuBe to system/app
#LOCAL_PRODUCT_MODULE := true
LOCAL_CERTIFICATE := PRESIGNED
LOCAL_DPI_VARIANTS := xxhdpi xhdpi hdpi mdpi
LOCAL_DPI_FILE_STEM := YouTube_$(my_src_arch)_%.apk
LOCAL_SRC_FILES := YouTube_$(my_src_arch)_xxhdpi.apk
...

...

当然网上也有人说，在google play store里面更新这些app,是一样的效果，更新这些app以后，这些app的目录变为了data/data/xxx 这样，所以也算跳过此项了。

当然最终问题的原因为：

GTS 工具版本更新，从R4更新为R1,这个时候我们再测试，就会PASS了。主要原因是因为第三个判断方法返回true,则此GTS会跳过此项。
