长时间使用之后手机变慢

现象描述:

长时间使用之后手机变慢

抓取java traceview如下显示:

system_server_slowly01

traceview显示是:

WindowsContianer.forAllWindows()占了大量CPU时间.

怀疑是anmimation相关的对象没有释放

用MAT抓取 hprof

有900个WindowStateAnimator对象

Class Name | Objects | Shallow Heap | Retained Heap

com.android.server.wm.WindowStateAnimator| 900 | 201,600 | >= 490,432

被mTokenMap 引用780次

mTokenMap java.util.HashMap @ 0x1340b950| 780 | 40 | 174,720 | 30,080

代码:
mTokenMap? 没有释放?

// Mapping from a token IBinder to a WindowToken object on this display.
private final HashMap<IBinder, WindowToken> mTokenMap = new HashMap();

1. 调用:removeWindowToken的地方:
   ./DisplayContent.java: removeAppToken(IBinder binder) {
   ./DisplayContent.java:855: final WindowToken token = removeWindowToken(binder);

./WindowManagerService.java: public void removeWindowToken(IBinder binder, int displayId) {
./WindowManagerService.java:2496: final WindowToken token = dc.removeWindowToken(binder);
./WindowManagerService.java:7530: public void removeWindowToken(IBinder binder, boolean removeWindows, int displayId) {
./WindowManagerService.java:7540: final WindowToken token = dc.removeWindowToken(binder);
./WindowManagerService.java:7549: WindowManagerService.this.removeWindowToken(binder, displayId);

./WindowToken.java:239: mDisplayContent.removeWindowToken(token);

---

2. 调用:removeAppToken 的地方:
   ./AppWindowContainerController.java:246: dc.removeAppToken(mToken.asBinder());

---

从上述查看:
WindowToken 对象和
AppWindowContainerController对象

Class Name | Objects | Shallow Heap | Retained Heap

com.android.server.wm.AppWindowToken| 905 | 181,000 | >= 1,169,272

Class Name | Objects | Shallow Heap | Retained Heap

com.android.server.wm.AppWindowContainerController| 904 | 43,392 | >= 116,032

都是没有释放的.

分析WindowStateAnimator 的释放过程,找出不释放的原因

加上LOG:

WindowToken removeWindowToken(IBinder binder) {
    android.util.Log.w("jackywei","removeWindowToken");
    android.util.Log.w("jackywei",android.util.Log.getStackTraceString(new Throwable()));
    android.util.Log.w("jackywei","++++++++++++++++++++removeWindowToken++++++++++++++++++++");
    final WindowToken token = mTokenMap.remove(binder);
    if (token != null && token.asAppWindowToken() == null) {
        token.setExiting();
    }
    return token;
}

应用died的时候会主动释放:

下面这个hold住了 29 个ComposeMessageActivity

Class Name | Ref. Objects | Shallow Heap | Ref. Shallow Heap | Retained Heap

mArray java.lang.Object[180] @ 0x14d79ce8| 29 | 736 | 19,256 | 736

下面这个hold住了 32 个 ConversationList

Class Name | Ref. Objects | Shallow Heap | Ref. Shallow Heap | Retained Heap

mArray java.lang.Object[180] @ 0x14d79ce8| 32 | 736 | 11,520 | 736

也就是说因为某种原因ConversationList压根没有被释放

排除com.android.mms的问题

adb shell kill -9 com.android.mms

问题依然存在.但是,这些对象都有所减少.

Class Name | Objects | Shallow Heap | Retained Heap

日了狗了…哎.

找出申请和释放 WindowStateAnimator的地方,加上LOG,再测试复现

kill 了 所有 com. 打头的APP,

还是需要在system_server里面排查未释放的原因.

可以在 ActivityRecord 里面找对应的 strings.
