Question

我正在开发一个Android项目，我需要将一个mp3文件发布到PHP服务器。当mp3文件很小时，我可以将它成功发布到服务器，但是当mp3文件大小为3-4 MB时，我在名字对中出错。在这里我发布我的错误和代码。可能是什么问题？

以下代码适用于onActivityResult（），我将mp3文件转换为Base64格式。

if (resultCode == RESULT_OK) {
    if (requestCode == RQS_OPEN_AUDIO_MP3) {
        Uri audioFileUri = data.getData();

        Toast.LENGTH_LONG).show();

        Log.e("Mp3 Path==>", data.getData() + "");
        Log.e("Mp3 URI==>", audioFileUri + "");
        String path = ConstantData.getPath(this, audioFileUri);

        File file = new File(path);
        Log.e("File Length==>", file.length() + "");
        b=null;
        b= new byte[(int) file.length()];

        fileInputStream=null;
        encode=null;

        fileInputStream = new FileInputStream(file);
        fileInputStream.read(b);
        fileInputStream.close();        
        encode = Base64.encodeBytes(b);
        //Log.e("Mp3 Encoded==>", encode + "");     
        showImagePostingDialog("Upload?", "You want To Upload this Mp3 File?", null);
    }
}

这是我在NameValuePair Log收到的错误doInBackground()。
