Question

我正在开发一个Android应用程序，我从图片库中取出并上传到Dropbox。我的问题是fileinputstream无法找到该文件。请帮助代码如下，还有日志消息

public class UplodeFileToDropBox extends AsyncTask<Void , Void ,Boolean>{
private  Context context ;
private  DropboxAPI dropboxAPI ;
private  File imagefile ;
private  String dropboxpath ;



public UplodeFileToDropBox(Context context, DropboxAPI dropboxAPI, String dropboxpath, File imagefile)
{
     super();
     this.context = context ;
     this.dropboxAPI = dropboxAPI ;
     this.dropboxpath = dropboxpath ;
     this.imagefile = imagefile ;

}


@Override
protected Boolean doInBackground(Void... voids) {

    try
    {
        FileInputStream inputStream = new FileInputStream(imagefile);

        Log.i("DbExampleLog", inputStream.toString());

        dropboxAPI.putFile(dropboxpath, inputStream, imagefile.length(), null, null);
        return true ;
    }
    catch (DropboxException e)
    {
        Log.i("DbexEpshon",e.getMessage() );
    }
    catch (FileNotFoundException e)
    {
        Log.i("DbExampleLog", e.getMessage());
    }

    return  false ;
}
@Override
protected void onPostExecute(Boolean result) {
    if (result)
    {
        Toast.makeText(context, "File has been upLoded", Toast.LENGTH_LONG).show();
    }
    else
    {
        Toast.makeText(context , "Error wile loding" , Toast.LENGTH_LONG).show();
        Log.e("DbExampleLog", "Something went wrong while uploading.");
    }
}

}
