Qasid Ahmad Sadiq 4d70022b88 Revert "Fix a11y cache correctness bug"
This fix introduced a painful crash that ends up disabling accessibility
services for certain users.
This happens when a client of AccessibilityCache tries to add a node, with the same id as a node previously in the cache, but fewer children, where the removed child is not in the cache.
This is because, when children are removed, and a the node is updated, the cache tries to clear the child trees. But if the child is not in the cache, the cache clears the whole tree. Every node is recycled.
Then the original node being replaced is attempted to be recycled again, and voila crash.

The fix also didn't fix the original issue based on the discussion in
b/114133438.

The risk for this is pretty low, since nothing was built on top of this.

This reverts commit 2f69c16c3d.
Bug: 124676705
Test: Tested to see if above usecase still happens.

INTRODUCTION

The Android platform core tests (APCT) consist of unit tests for core platform
functionality. These differ from CTS in that they are not necessarily testing
public APIs and are not guaranteed to work outside of AOSP builds.


INSTRUCTIONS

To run a test or set of tests, first build the FrameworksCoreTests package:

  make FrameworksCoreTests

Next, install the resulting APK and run tests as you would normal JUnit tests:

  adb install -r ${ANDROID_PRODUCT_OUT}/data/app/FrameworksCoreTests/FrameworksCoreTests.apk
  adb shell am instrument -w \
    com.android.frameworks.coretests/android.support.test.runner.AndroidJUnitRunner

To run a tests within a specific package, add the following argument AFTER -w:

    -e package android.content.pm

To run a specific test or method within a test:

    -e class android.content.pm.PackageParserTest
    -e class android.content.pm.PackageParserTest#testComputeMinSdkVersion

To run tests in debug mode:

    -e debug true

To uninstall the package:

  adb shell pm uninstall -k com.android.frameworks.coretests

For more arguments, see the guide to command=line testing:
