当导航应用程序app由于pjsip而崩溃时，它说你必须用pjsip线程注册外部线程。我还使用像这样的主线程注册了pjsip
try {
mEndpoint.libRegisterThread(Thread.currentThread().getName());
Log.d(TAG, "Registering with thread "+Thread.currentThread().getName());
} catch (Exception e) {
e.printStackTrace();
}
这个崩溃发生的事情是如此随机，并且不知道是什么导致了这一点，而且当崩溃发生时我也没有调用任何pjsip方法。那么这里出了什么问题？

答案 0 :(得分：1)
看起来GC中的一个PjSip对象是从您注册的线程以外的线程中收集的。
根据文件：
... application ‘’‘MUST immediately destroy PJSUA2 objects using object’s delete()
method (in Java)’‘’, instead of relying on the GC to clean up the object
所以你必须手动删除PjSip对象，例如：
account.delete();
