一 疑难问题打开protolog

- configuration变化导致界面闪烁
问题背景：str待机开机后，初次按键后整个页面发生刷机，查看eventlog发现activity声明周期重新走了一遍
解决方案：
<activity android:name=".MyActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize" /> - 应用通过exit(0)退出导致黑屏问题
- activity没有执行oncreate导致inr（input dispatcher timeout）
- activity不响应声明周期调度
- activity生命周期走到onstop，导致数据被清理。
问题描述：
从tvapp点击settings跳转到setting界面后，liveTV不应该执行onstop，但是异常情况下，onstop被调用。
问题分析：
正常情况下，也会将liveTV添加到stopping列表，但是下一个activity idle时并不会执行liveTV的stop方法。异常时执行了stop
10-28 19:40:46.030 819 5306 I wm_add_to_stopping: [0,206791775,com..tv/com..player.TVActivity,makeInvisible]
执行onstop前会判断：
不执行onstop
app的animating从true变成false导致问题发生
final boolean animating = s.isAnimating(TRANSITION | PARENTS,
ANIMATION_TYPE_APP_TRANSITION | ANIMATION_TYPE_RECENTS)

animating为什么会变，待续。。。

- 上一个应用finish自己，然后launcher的resume没有被调用
结论主线程卡顿导致。
2.洪恩识字拒绝权限出现黑屏
根因：应用执行kill自己进程逻辑，系统判断逻辑异常，不会继续切换Activity. - finishIfPossible()方法会进行task的切换。
[ActivityRecord.java]
// We are finishing the top focused activity and its task has nothing to be focused so
// the next focusable task should be focused.
if (mayAdjustTop && ((ActivityStack) task).topRunningActivity(true /* focusableOnly */)
== null) {
task.adjustFocusToNextFocusableTask("finish-top", false /* allowFocusSelf */,
shouldAdjustGlobalFocus);
}
- 前台activity进程死亡也会进行task的切换。
但是三方应用在生命周期内调用完finish后kill了自己导致异常产生。
