示例1: initFile
void Sound::initFile(const std::string &name) {
SLresult result;
std::string filename = name + ".mp3";
// use asset manager to open asset by filename
AssetLoader *loader = AssetLoader::instance();
AAsset *asset = loader->open(filename);
// the asset might not be found
if (NULL == asset) {
LOGI("Asset not found: %s", name.c_str());
return;
}
// open asset as file descriptor
off_t start, length;
int fd = AAsset_openFileDescriptor(asset, &start, &length);
assert(0 <= fd);
AAsset_close(asset);
// configure audio source
SLDataLocator_AndroidFD loc_fd = {SL_DATALOCATOR_ANDROIDFD, fd, start, length};
SLDataFormat_MIME format_mime = {SL_DATAFORMAT_MIME, NULL, SL_CONTAINERTYPE_UNSPECIFIED};
SLDataSource audioSrc = {&loc_fd, &format_mime};
// configure audio sink
SLDataLocator_OutputMix loc_outmix = {SL_DATALOCATOR_OUTPUTMIX, pd->outputMixObject};

// create audio player
