我正在使用Expo构建一个react原生应用程序。我用的是“EXPO-AV”。
我无法在后台播放我的音频文件。
我有以下的，但仍然不能使它工作，当我切换我的应用程序到另一个应用程序。我没有任何错误；音乐就停在我的应用程序里了。有什么建议可以让它工作吗？或者我的代码可能出了问题？
async componentDidMount() {
try {
await Audio.setAudioModeAsync({
allowsRecordingIOS: false,
interruptionModeIOS: Audio.INTERRUPTION_MODE_IOS_MIX_WITH_OTHERS,
// interruptionModeIOS: Audio.INTERRUPTION_MODE_IOS_DUCK_OTHERS,
playsInSilentModeIOS: true,
interruptionModeAndroid: Audio.INTERRUPTION_MODE_ANDROID_DUCK_OTHERS,
shouldDuckAndroid: true,
staysActiveInBackground: true,
playThroughEarpieceAndroid: true
})
this.loadAudio();
// this.interval = setInterval(() => this.getStatus(), 1000);
} catch (e) {
console.log(e)
}
}
每件事都使用这样的参数：
Audio.setAudioModeAsync({
allowsRecordingIOS: false,
staysActiveInBackground: true,
interruptionModeIOS: Audio.INTERRUPTION_MODE_IOS_DUCK_OTHERS,
playsInSilentModeIOS: true,
shouldDuckAndroid: true,
interruptionModeAndroid: Audio.INTERRUPTION_MODE_ANDROID_DUCK_OTHERS,
playThroughEarpieceAndroid: false
});
在package.json“expo-av”：“^6.0.0”中,
在播放机中：
componentDidMount() {
Audio.setAudioModeAsync({
allowsRecordingIOS: false,
staysActiveInBackground: true,
interruptionModeIOS: Audio.INTERRUPTION_MODE_IOS_DUCK_OTHERS,
playsInSilentModeIOS: true,
shouldDuckAndroid: true,
interruptionModeAndroid: Audio.INTERRUPTION_MODE_ANDROID_DUCK_OTHERS,
playThroughEarpieceAndroid: false
});
this._loadNewPlaybackInstance(true);
}
async _loadNewPlaybackInstance(playing) {
if (this.playbackInstance != null) {
await this.playbackInstance.unloadAsync();
this.playbackInstance = null;
}
const source = { uri: 'http://music.ru/music.mp3' };
const initialStatus = {
shouldPlay: playing,
rate: this.state.rate,
shouldCorrectPitch: this.state.shouldCorrectPitch,
volume: this.state.volume,
isMuted: this.state.muted,
isLooping: this.state.loopingType === LOOPING_TYPE_ONE
// // UNCOMMENT THIS TO TEST THE OLD androidImplementation:
// androidImplementation: 'MediaPlayer',
};
const {sound, status} = await Audio.Sound.createAsync(
source,
initialStatus,
this._onPlaybackStatusUpdate
);
this.playbackInstance = sound;
