我们正致力于通过texureview展示需要硬件加速的视频。 一切都很好，生活很幸福，直到我们解决这个问题。

这是崩溃堆栈信息：

从上面的信息中我们发现SurfaceTexture.cpp

中发生了错误 
if (mEglContext != ctx && mEglContext != EGL_NO_CONTEXT) {
    ST_LOGE("detachFromContext: invalid current EGLContext");
    return INVALID_OPERATION;
}

我们通过listview使用缓存的textureview，但我们不知道这是否是问题所在。我们不擅长OpenGL，我们对硬件加速的机制知之甚少。

有人可以帮忙吗？
