如何分析应用的焦点被抢了

在system log 中查找:WindowManager: Set focused app to

比如下面的:

05-04 15:48:25.339531  1122 20690 V WindowManager: Set focused app to: AppWindowToken{48a2124 token=Token{e66c5b7 ActivityRecord{5c1a4b6 u0 com.yixia.videoeditor/com.igexin.sdk.GActivity t36}}} old focus=AppWindowToken{46a7889 token=Token{1ff790 ActivityRecord{8658253 u0 com.tencent.mm/.ui.LauncherUI t38}}} moveFocusNow=true

这个就是在微信页面焦点被com.igexin.sdk.GActivity 抢掉了.
