enum AndroidLeakFixes : Enum<AndroidLeakFixes>
A collection of hacks to fix leaks in the Android Framework and other Google Android libraries.
| SPELL_CHECKER | [androidJvm] SPELL_CHECKER() Every editable TextView has an Editor instance which has a SpellChecker instance. SpellChecker is in charge of displaying the little squiggle spans that show typos. SpellChecker starts a SpellCheckerSession as needed and then closes it when the TextView is detached from the window. A SpellCheckerSession is in charge of communicating with the spell checker service (which lives in another process) through TextServicesManager. |
| IMM_CUR_ROOT_VIEW | [androidJvm] IMM_CUR_ROOT_VIEW() When an activity is destroyed, the corresponding ViewRootImpl instance is released and ready to be garbage collected. Some time after that, ViewRootImpl#W receives a windowfocusChanged() callback, which it normally delegates to ViewRootImpl which in turn calls InputMethodManager#onPreWindowFocus which clears InputMethodManager#mCurRootView. |
| IMM_FOCUSED_VIEW | [androidJvm] IMM_FOCUSED_VIEW() Fix for https://code.google.com/p/android/issues/detail?id=171190 . |
| VIEW_LOCATION_HOLDER | [androidJvm] VIEW_LOCATION_HOLDER() In Android P, ViewLocationHolder has an mRoot field that is not cleared in its clear() method. Introduced in https://github.com/aosp-mirror/platform_frameworks_base/commit /86b326012813f09d8f1de7d6d26c986a909d |
| ACTIVITY_MANAGER | [androidJvm] ACTIVITY_MANAGER() Samsung added a static mContext field to ActivityManager, holding a reference to the activity. |
| LAST_HOVERED_VIEW | [androidJvm] LAST_HOVERED_VIEW() mLastHoveredView is a static field in TextView that leaks the last hovered view. |
| BUBBLE_POPUP | [androidJvm] BUBBLE_POPUP() A static helper for EditText bubble popups leaks a reference to the latest focused view. |
| SAMSUNG_CLIPBOARD_MANAGER | [androidJvm] SAMSUNG_CLIPBOARD_MANAGER() ClipboardUIManager is a static singleton that leaks an activity context. This fix makes sure the manager is called with an application context. |
| CONNECTIVITY_MANAGER | [androidJvm] CONNECTIVITY_MANAGER() ConnectivityManager has a sInstance field that is set when the first ConnectivityManager instance is created. ConnectivityManager has a mContext field. When calling activity.getSystemService(Context.CONNECTIVITY_SERVICE) , the first ConnectivityManager instance is created with the activity context and stored in sInstance. That activity context then leaks forever. |
| ACCESSIBILITY_NODE_INFO | [androidJvm] ACCESSIBILITY_NODE_INFO() Until API 28, AccessibilityNodeInfo has a mOriginalText field that was not properly cleared when instance were put back in the pool. Leak introduced here: https://android.googlesource.com/platform/frameworks/base/+ /193520e3dff5248ddcf8435203bf99d2ba667219%5E%21/core/java/android/view/accessibility /AccessibilityNodeInfo.java |
| FLUSH_HANDLER_THREADS | [androidJvm] FLUSH_HANDLER_THREADS() HandlerThread instances keep local reference to their last handled message after recycling it. That message is obtained by a dialog which sets on an OnClickListener on it and then never recycles it, expecting it to be garbage collected but it ends up being held by the HandlerThread. |
| USER_MANAGER | [androidJvm] USER_MANAGER() Obtaining the UserManager service ends up calling the hidden UserManager.get() method which stores the context in a singleton UserManager instance and then stores that instance in a static field. |
| TEXT_LINE_POOL | [androidJvm] TEXT_LINE_POOL() This flushes the TextLine pool when an activity is destroyed, to prevent memory leaks. |
| MEDIA_SESSION_LEGACY_HELPER | [androidJvm] MEDIA_SESSION_LEGACY_HELPER() MediaSessionLegacyHelper is a static singleton and did not use the application context. Introduced in android-5.0.1_r1, fixed in Android 5.1.0_r1. https://github.com/android/platform_frameworks_base/commit/ 9b5257c9c99c4cb541d8e8e78fb04f008b1a9091 |
