android spotify ERROR分离线程与interp帧(count = 28)

作者:互联网

我正在做一个android项目,需要集成Spotify流功能.
现在我可以加载动态库和调用函数,但是有一些问题.

callbacks.notify_main_thread = callback_notify_main_thread;
config.callbacks = &callbacks;
error = sp_session_create(&config, &session);

然后在回调函数notify_main_thread中,它将:

vm->AttachCurrentThread( &env, NULL );
vm->DetachCurrentThread();

这个回调函数仍然在native thread created by Spotify c code(参见问题“根据做文档,一些回调是从’内部会话线程’调用的.这是什么意思?”).

所以首先我将当前线程附加到javaVM并获取JNIEnv,然后调用java方法,稍后将其分离.但是在执行DetachCurrentThread时它会崩溃:

而如果

//vm->DetachCurrentThread();

然后调用sp_session_create(),它永远不会返回错误代码.

解决方法:

问题解决了,我使用javaVM-> GetEnv()检查当前线程是否已经附加到vm,而不是直接附加线程并获取JNIEnv.
