这是我的代码，我在服务中有两个参数＆＃34; userquestion [question_id]＆＃34;和＆＃34; userquestion [长相] [0] [照片]＆＃34;一个用于文本，另一个用于图像，请告诉我如何使用此代码保存此内容
这是我的logcat

使用此代码..
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.annag);
try {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bm.compress(CompressFormat.JPEG, 75, bos);
byte[] data = bos.toByteArray();
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost(url_path);
ByteArrayBody bab = new ByteArrayBody(data, "forest.jpg");
// File file= new File("/mnt/sdcard/forest.png");
// FileBody bin = new FileBody(file);
MultipartEntity reqEntity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("store_name", new StringBody("amazon"));
reqEntity.addPart("file", bab);
postRequest.setEntity(reqEntity);
HttpResponse response = httpClient.execute(postRequest);
String my_response = convertStreamToString(response.getEntity()
.getContent());
Toast.makeText(getApplicationContext(), my_response,
Toast.LENGTH_LONG).show();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

试试这个：
Android方面：

if (!sourceFile.isFile()) {
dialog.dismiss();
Log.e("uploadFile", "Source File not exist :"
+uploadFilePath + "" + uploadFileName);
runOnUiThread(new Runnable() {
public void run() {
messageText.setText("Source File not exist :"
