system_server内存泄漏

卡顿原因:

用android Device Monitor 获取的文件中:
ddms8967132311110557686.trace

windowContainer.ForAllWindows 超过2.7秒

抓取 hprof文件分析:
找到和ForAllWindows函数相关的对象:

adb shell ps | grep -i system_server

ps = 923

adb shell am dumpheap 923 /data/local/tmp/923.hprof

I use the sdk tools catch the systrace log ,the log indicate that the android.anim thread spend a lot of cpu time.
And I catch the traceview log, the log indicate that the com.android.server.wm.WindowContainer.forAllWindows function spend a lot of time to run in the android.anim thread.

And I catch the window service log,show that there are so lot of AppWindowToken is not released.

直接debug system_server 看能否释放

sudo mount -t cifs -o username=”android”,password=”mobile#5” //10.1.6.36/android /mnt/10.1.6.36

用eclipse远程调试

删除一个APP 看能否正常释放:

if (!mTraversalScheduled) {

    mService.mAnimationHandler.post(mPerformSurfacePlacement); //替换?

第一次进入animate 会再次调用 scheduleAnimation() 是否下次还需要走 animate 取决与条件 mAnimationFrameCallbackScheduled
mAnimationFrameCallbackScheduled初始话默认是 false

void scheduleAnimation() {
    if (!mAnimationFrameCallbackScheduled) {
        mAnimationFrameCallbackScheduled = true;
        mChoreographer.postFrameCallback(mAnimationFrameCallback);
    }
}

取消下一次 animate 即 mChoreographer.removeFrameCallback(mAnimationFrameCallback);
private void cancelAnimation() {
if (mAnimationFrameCallbackScheduled) {
mAnimationFrameCallbackScheduled = false;
mChoreographer.removeFrameCallback(mAnimationFrameCallback);
}
}

但是函数里面有一个判断条件:
if (mService.mDragState != null) {
mAnimating |= mService.mDragState.stepAnimationLocked(mCurrentTime);
}

if (!mAnimating) {
    cancelAnimation();
}

整体的代码如下:
private void animate(long frameTimeNs) {

    synchronized (mService.mWindowMap) {
        if (!mInitialized) {
            return;
        }

        // Schedule next frame already such that back-pressure happens continuously
        scheduleAnimation();                                    //这里先预定下一帧
    }

    // Simulate back-pressure by opening and closing an empty animation transaction. This makes
    // sure that an animation frame is at least presented once on the screen. We do this outside
    // of the regular transaction such that we can avoid holding the window manager lock in case
    // we receive back-pressure from SurfaceFlinger. Since closing an animation transaction
    // without the window manager locks leads to ordering issues (as the transaction will be
    // processed only at the beginning of the next frame which may result in another transaction
    // that was executed later in WM side gets executed first on SF side), we don't update any
    // Surface properties here such that reordering doesn't cause issues.
    mService.executeEmptyAnimationTransaction();

    synchronized (mService.mWindowMap) {
        mCurrentTime = frameTimeNs / TimeUtils.NANOS_PER_MS;
        mBulkUpdateParams = SET_ORIENTATION_CHANGE_COMPLETE;
        mAnimating = false;                                    //每次都会设置为false
