Best way to send large data to server in Android

I have zip file in my sdcard,size is 8-9 mb.I'm using this library to send data.


https://github.com/loopj/android-async-http


and this is my source

private void sendSubmitRequest(File file)
{
AsyncHttpClient client = new AsyncHttpClient();

RequestParams params = new RequestParams();
showpDialog("loading");

try
{

params.put("vin", vinNumber.getText().toString());
params.put("polygon", polygonAdapter.getItem(spinnerPosition).getId()+"");


params.put("scanner_key", vinScannerModel.getSecretKey());
params.put("status", status);
params.put("user", vinScannerModel.getId()+"");

InputStream inputStream = null;
inputStream = new FileInputStream(file.getAbsolutePath());
byte[] buffer = new byte[8192];
int bytesRead;
ByteArrayOutputStream output = new ByteArrayOutputStream();
Base64OutputStream output64 = new Base64OutputStream(output, Base64.DEFAULT);
try {
while ((bytesRead = inputStream.read(buffer)) != -1) {
output64.write(buffer, 0, bytesRead);
}
} catch (IOException e) {
e.printStackTrace();
}
output64.close();

String attachedFile = output.toString();


params.put("photos", attachedFile);

}
catch (Exception e)
{
e.printStackTrace();
}


client.post(ServerUtil.addVin, params, new TextHttpResponseHandler() {
@Override
public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {

showOneItemDialog(throwable.toString(),false);
hidepDialog();


Log.d("server status",responseString+"");
}

@Override
public void onSuccess(int statusCode, Header[] headers, String responseString) {
Log.d("server status",responseString+"");
try {
hidepDialog();
JSONObject mainJsonObject = new JSONObject(responseString.toString());
boolean status=mainJsonObject.getBoolean("status");
String desc=mainJsonObject.getString("desc");
if(desc!=null)
showOneItemDialog(desc,status);
} catch (JSONException e) {
e.printStackTrace();
showOneItemDialog(e.toString(),false);
}
}
});




}


My code working perfect but i want to check if my solution is complete?

Answer

You will want to run this in an upload Service instead of as part of the Activity/UI. If the user kills the Activity (or if it's otherwise removed due to memory pressure), you'll lose the upload.

I haven't used this particular library, but one like this seems like something you'll find useful and a quick glance shows it has most of the features one generally needs: https://github.com/gotev/android-upload-service
