安卓调用相册出错不选择图片推出后无法再次选择

onActivityResult加上判断条件 若果没有选择返回null

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode != Activity.RESULT_OK) {
        if (Build.VERSION.SDK_INT >= 21){
            mUploadCallbackAboveL.onReceiveValue(null);
        }else {//4.4以下处理
            mUploadMessage.onReceiveValue(null);
        }
    }
    if (requestCode==0&&resultCode==-1) {

        if (Build.VERSION.SDK_INT >= 21) {//5.0以上版本处理
            Uri uri = data.getData();
            Uri[] uris = new Uri[]{uri};
               /* ClipData clipData = data.getClipData();  //选择多张
                if (clipData != null) {
                    for (int i = 0; i < clipData.getItemCount(); i++) {
                        ClipData.Item item = clipData.getItemAt(i);
                        Uri uri = item.getUri();
                        uris[i]=uri;
                    }
                }*/
            mUploadCallbackAboveL.onReceiveValue(uris);//回调给js
        } else {//4.4以下处理
            Uri uri = data.getData();
            mUploadMessage.onReceiveValue(uri);
