[英]server takes too much time to upload the multiple images in android
我的Android應用程序正在服務器上上傳單個以及多個圖像。 如果我上傳單個圖像則沒有問題,但是如果我選擇多個圖像(8-10),則需要花費大量時間在服務器上上傳。
請幫幫我。
class asyncImageUploader extends AsyncTask<String, Integer, String>{
String methodName = "UploadImageWithDetail" ;
ProgressDialog progressDialog;
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
progressDialog = LoginActivity.createProgressDialog(CaseDetailsActivity.this);
//progressDialog = new ProgressDialog(CaseDetailsActivity.this);
//progressDialog.show();
}
@Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
for(int i = 0 ; i<arrImagePath.size() ; i++)
{
try{
Options options = new BitmapFactory.Options();
options.inSampleSize = 2;
Bitmap bitmap = BitmapFactory.decodeFile(arrImagePath.get(i), options);
bitmap = Bitmap.createScaledBitmap(bitmap, 600, 600, true);
ByteArrayOutputStream buffer = new ByteArrayOutputStream(bitmap.getWidth() * bitmap.getHeight());
bitmap.compress(CompressFormat.PNG, 100, buffer);
imageByteStr = Base64.encodeToString(buffer.toByteArray(), Base64.DEFAULT);
}catch(Exception e){
e.printStackTrace();
}
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(6);
nameValuePairs.add(new BasicNameValuePair("loginID",sharedPreferences.getString("username", "")));
nameValuePairs.add(new BasicNameValuePair("loginKey", sharedPreferences.getString("password", "")));
nameValuePairs.add(new BasicNameValuePair("HostCompID", sharedPreferences.getString("hostID", "")));
nameValuePairs.add(new BasicNameValuePair("LoginCompID", sharedPreferences.getString("logID", "")));
nameValuePairs.add(new BasicNameValuePair("caseID", caseId));
nameValuePairs.add(new BasicNameValuePair("byteImageString", imageByteStr));
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(RxOfficeUtilities.URL+methodName);
try {
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
return null;
}
@Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
progressDialog.dismiss();
}
我會說,與其在每個循環中創建一個http客戶端,不如嘗試使用一個http客戶端。 此外,請在每個循環的結束時關閉緩沖區,或嘗試將其重置。
