startActivityForResult闪退和startActivityForResult无法启动

前言

近期开发的语音采集App某个用户登录后界面打不开，问题是：startActivityForResult闪退和startActivityForResult无法启动。报如下的提示：

解决过程

开始对这个问题并不熟悉，用户只是说App闪退，用其它用户登录，能正常打开Intent，所以排除流程问题，也排除了audio设备对象的问题；在数据量上和其它用户对应也不高，就回到现场，设置断点跟踪，定位到startActivityForResult函数调用行，这函数打开Intent界面，Intent界面打不开，当然要怀疑界面的成员了。把界面里的数组成员注释后，问题解决。

总结

startActivityForResult调用Intent出下面问题，Intent里有个数组，数组有数组项，项太多占内存就出问题，数组换成非数组形式传递，问题解决。

表现到audio设备对象上，可能是audio设备太占内存促成，其实和audio设备对象没关系。
