android - Android 音乐流媒体应用程序上的致命信号 11

Question

我正在使用这个项目在 Android 设备上编写音乐流应用程序:https://github.com/spotify/psyonspotify

不幸的是，我的应用程序随机崩溃。我尝试使用 ndk-stack 调试 C 代码。根据输出，问题出在以下行:

assert(SL_RESULT_SUCCESS != result);

(sounddriver.cpp 中的 l.92)。我尝试更改和/或注释掉这一行，但错误仍然存​​在......

这似乎是与不正确的内存分配相关的某种问题，但它似乎与缓冲区大小没有任何关系，因为似乎还有足够的存储大小(请参阅日志输出)

不幸的是，我在处理或调试 C 代码方面经验不足。如果有人能指出我正确的方向，那就太好了!谢谢。

如果 assert(SL_RESULT_SUCCESS != result); 正在触发，则您的问题与 SLresult result = (*bqPlayerBufferQueue)->Enqueue(bqPlayerBufferQueue, buffer, size); 有关


SLAndroidSimpleBufferQueueItf 在 OpenSL 中实现。在尝试排队到缓冲区之前，您是否使用 init_audio_player() 正确初始化了音频播放器？

调试的一些想法:探索 SLAndroidSimpleBufferQueueItf 以了解其接口(interface)并在调用 Enqueue 之前验证是否满足所有假设。还要查找它提供的其他返回代码。如果它提供了有用的错误代码，将使您的生活更轻松。

还要看看如何调用 psyonspotify.so，以确保您正确遵守其接口(interface)和假设(即所需的任何 init 函数)。
