最近项目要求集成三方锁屏应用代替原生swipe锁屏，出现了几个CTS/GTS问题，记个小笔记
1.因为三方锁屏需要完全替代掉原生swipe，所以将swipe禁用掉了，Settings中也是不可以选的，结果出现
[Google CTS]android.app.usage.cts.UsageReportingTest#testSplitscreenSameTokenTwoMissedStop test failed
所以原生的swipe不能禁掉，只有退而求其次，修改Settings中的默认值，设置为none，但用户还是可以自己选择swipe的
2.下面这个是关于分屏的，在home界面设置应用分屏，灭屏再亮屏，由于三方锁屏应用不支持分屏，所以home的分屏也退出了，此问题需要有三方提供fix方案
[Google CTS]android.server.wm.lifecycle.ActivityLifecycleKeyguardTests#testKeyguardShowHideOverSplitScreen test failed

3.这条报的是应用不能被授与READ_EXTERNAL_STORAGE权限，后面发现是测试同事操作有误，在跑GTS之前已经手动允许了此权限，将此应用所有权限关闭即PASS
[Google GTS]com.google.android.permission.gts.DefaultPermissionGrantPolicyTest#testDefaultGrantsWithRemoteExceptions test failed
java.lang.AssertionError: packageName: com.celltick.lockscreen { priv app: true targetSDK: 29 uid: 10141 persistent: false signature: EBAE3776F53F039F8CB785195D53F0D20E783346EA5AC078FAF97E187EE5D216 on system image: true has platform signature: false message: cannot be granted by default to package { permission: android.permission.READ_EXTERNAL_STORAGE } }
以此为笔记记录
