Android万能音频播放器09-添加播放切换功能

在调用stop方法后回调一个函数，然后在函数里面判断是否播放下一个URL

private static boolean playNext = false;


public void onCallPlayNext(){
    if (playNext){
        playNext = false;
        prepared();
    }
}

切换时将资源释放再重新播放

/**
 * 播放下一曲回调
 */
public void onCallPlayNext(){
    if (playNext){
        playNext = false;
        prepared();
    }
}

JNIEXPORT void JNICALL

    if (!nexit){
        return;
    }
    // TODO

    jclass jclz = env->GetObjectClass(instance);
    jmethodID jmid_play_next = env->GetMethodID(jclz,"onCallPlayNext","()V");

    nexit = false;
    if (ffmpeg != NULL){
        ffmpeg->release();
        delete(ffmpeg);
        ffmpeg = NULL;

        if (callJava != NULL){
            delete(callJava);
            callJava = NULL;
        }
        if (playStatus != NULL){
            delete(playStatus);
            playStatus = NULL;
        }
    }
    nexit = true;

    env->CallVoidMethod(instance,jmid_play_next);
}
