新手,请教。小弟使用自定义Dialog和ExpandableListView 显示数据,但是却导致整个Activity闪退。
我思路是,使用Service 监听蓝牙BLE的广播的数据,然后Service通过Brodcast 的形式,将数据发送到Activity中,
然后,Activity的BroadcasrReciver 通过Hanler 显示对话框。 结果,就闪退了。。显示如下错误:

http://blog.csdn.net/a5nan/article/details/51517根据这个log找到了解决方案:android studio 2.0中使用了instant run功能,把这个功能关闭就ok了。因为instant run本身的机制影响了一些classloader的加载。

没接触过这类异常。你先看看楼下的解决方案有没有效果。
是这样子的,如果,我不往mListBluetoothLEGattServiceJaveBean这个List 添加数据,及Adapter 为空的时候,对话框是可以显示出来的。
但是,只要Adapter 里面有数据,就会出现上面的问题。
都调试了很久,无论是单步调试,还是其他的,还是找不到原因,快无语了。

不是都是在UI线程显示对话框吗?????

所以你这个闪退应该是数据相关的。那么你的日志是看不出这点的。
应该是你的Handler没有处理好。
本人觉得,接口还是最好用的,可以试试用接口来处理数据返回后去更新UI这个问题。
handler 不是用来在线程中,发送消息,然后在UI线程中更新UI???????
