此文章只是一篇总结，针对 MTK 平台近期的 CTS STS 做个简单的整理回顾，后期不断扩展
- CTS 专区
CtsLocationPrivilegedTestCases android.location.cts.privileged.GnssMeasurementValuesTest#testListenForGnssMeasurements
junit.framework.AssertionFailedError: Failing tests are:
(Test: FAIL) SatellitPvt is supported. The test must find a measurement with SatellitePvt within 75 seconds.
at junit.framework.Assert.fail(Assert.java:50)
at android.location.cts.common.SoftAssert.assertAll(SoftAssert.java:162)
at android.location.cts.privileged.GnssMeasurementValuesTest.testListenForGnssMeasurements(GnssMeasurementValuesTest.java:156)
此项需要特殊的测试条件，需要在 GPS 信号很好的地方或者室内装有 GPS 放大器，复测可以正常 pass 。
==================================================================================
CtsPermissionTestCases
android.permission.cts.ProviderPermissionTest#testManageDocuments
junit.framework.AssertionFailedError: Exactly one package (must be com.google.android.documentsui) can request the MANAGE_DOCUMENTS permission; found package com.android.contacts which must be revoked for security reasons at junit.framework.Assert.fail(Assert.java:50) at android.permission.cts.ProviderPermissionTest.testManageDocuments(ProviderPermissionTest.java:219)
此项是由于 MTK 平台的联系人权限导致的，在清单文件中注释掉 android.permission.MANAGE_DOCUMENTS
=====================================================================================

请申请patch:ALPS06359285
【非ago平台】
You can get a waiver bug id:225819430
Google的回复:
Our MediaProvider owner has merged the change into the internal branch and the Google built MediaProvider module will be made available in the future.
The waiver could be granted only if you are shipping a device that’s preloading Google built MediaProvider.
CTS_12_R3 工具waiver的，R4 工具并不waiver，最后申请 waiver，google 也同意了
