Question

我的代码在这里：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 1){
        if (resultCode == Activity.RESULT_OK){
            Uri selectdFileUri = data.getData();
            File file = new File(selectdFileUri.getPath().toString());
            Log.e(TAG, "File: "+file.getName() );
            uploadedFileName = file.getName().toString();
            Log.e(TAG, "FILE NAME: "+uploadedFileName );
            tokens = new StringTokenizer(uploadedFileName,":");
            first = tokens.nextToken();
            file_1 = tokens.nextToken().trim();
            Log.e(TAG, "FILE 1: "+file_1 );
        }
    }
}

我收到的错误：

我引用我发现的here

java.util.StringTokenizer也可以抛出NoSuchElementException   没有更多的标记或元素，你调用nextToken（）或   nextElement（）方法。

使用Stringtokenizer调用时摆脱此异常   在进行调用之前，hasMoreTokens（）或hashMoreElements（）   nextToken（）或nextElement（）。

我在执行意图，失败交付结果时遇到错误？
