android 设置别名总是报6002，帮忙看一下

android测试已经显示init push success，但设置别名总是报6002，图片如下：

代码如下：

```
componentDidMount() {
AppState.addEventListener('change',this._handleAppStateChange);
if (Platform.OS === 'android') {
JPushModule.initPush()
JPushModule.getInfo(map => {
this.setState({
statusText: this.state.statusText + ', ' +map.myImei + ', ' + map.myVersion,
// appkey: map.myAppKey,
// imei: map.myImei,
// package: map.myPackageName,
// deviceId: map.myDeviceId,
// version: map.myVersion
})
})
JPushModule.notifyJSDidLoad(resultCode => {
if (resultCode === 0) {
}
})
}
this.setJPAlias = (registrationId) => {
// if (this.state.alias !== undefined) {
JPushModule.setAlias('hellojpushtest123', map => {
if (map.errorCode === 0) {
// console.log('set alias succeed');
Alert.alert(
'OK提示',
'set alias succeed');
} else {
// console.log('set alias failed, errorCode: ' + map.errorCode);
Alert.alert(
'set alias failed',
'set alias failed, errorCode: ' + map.errorCode);
}
})
// }
}
JPushModule.getRegistrationID(this.setJPAlias);
