我想开发一个应用程序，我使用凹凸API。一切工作正常，第一次。不知何故，如果我按Home按钮并回到应用程序它会崩溃没有任何异常（有时它可以正常工作2或3次）。当我检查我有以下堆栈跟踪的logcat的：信号11（SIGSEGV），在android中使用凹凸API时的错误地址

凸点API包含的本地库到我的应用程序（libandroid-api.so）。为了连接到凹凸服务器，我正在使用服务，并在onStop期间（当我按Home键时）我unbinding服务和在onStart（当从后台恢复时）我会绑定服务。所以如果我继续这个解除绑定和绑定2或3次，我得到这个错误。
我已经做了一些关于这个信号的搜索（SIGSEGV），故障地址，并发现它发生在应用程序产生无效的内存引用时。我没有任何访问这个本地库。我不知道该怎么办。
