项目里面有个input调用系统相册功能，发现取消后第二次点击失效

<input   class="input-file" multiple="multiple"   ref="avatarInput" @change="changeImage($event)"  type="file" name="image" accept="image/*">

原因是相册取消后一直在等待结果返回。
private void uploadImgFromSysPhotos(int resultCode, Intent intent) {

    if (mUploadMessage != null) {//5.0以下
        Uri result = intent == null || resultCode != RESULT_OK ? null
                : intent.getData();
        mUploadMessage.onReceiveValue(result);
    } else if (uploadMessage != null) {//5.0+
        Uri[] uris = new Uri[1];
        uris[0] = intent == null || resultCode != RESULT_OK ? null
                : intent.getData();
        if (uris[0] != null) {
            uploadMessage.onReceiveValue(uris);
        } else
        //取消后代码走这里，所以返回个空给input。
         uploadMessage.onReceiveValue(null);

    }
    uploadMessage = null;
}
