出问题代码：

包名：mobi.acpm.inspeckage.Module
类名：PackageDetail

mPInfo.activities = pm.getPackageInfo(app, PackageManager.GET_ACTIVITIES).activities;

分析结论：

造成 Binder crash 抛出 RuntimeException 是因为获取应用PackageInfo中数据量太大了，超出了Binder可传递的最大容量，进而导致PackageManager崩溃。

解决方案：

• 如果只是用来判断APP是否存在，获取信息少（大小<1m）情况下不会异常
• 直接获取activitys（淘宝、微信）目前只能通过解析AndroidManifest.xml获取（或者期待后续Binder机制更新吧）
