onMayBeBlackScreen中没有杀进程吧 @liulance

[liulance]

需要在哪里杀死进程？能否详细告知下，谢谢

[android-notes]

view绘制过程（measure，layout，draw）包括recyclerview onbindview中抛出异常可能会导致什么都不显示，这种情况会调用onMayBeBlackScreen。比如当前A act中的recyclerview中bindview时抛出了异常，这时虽然该recyclerview还可以滚动，点击，并且可以返回到上一个act时，但如果从A act打开新的act B，然后关闭B返回A时，可能A就什么都不显示了，并且这时再次按返回按键的话可能无法关闭A，不好判断到底是哪个act中的view抛出的异常，所以建议杀进程 。

你用的是2.0版本还是1.0的 @liulance

[open9527]

直接在activity/fragment中执行 int i= Integer.valueOf(null); 这种代码好像不能防止AppCrash.

生命周期抛出的异常会关闭act，但不会终止进程 @open9527
