How to upload multiple image from gallery in android?

I want to upload multiple image from gallery to server but getting only one image not multiple.
following is the code for it
FirstFragment.java
private void orderRequest() {
final OrderRequestModel model = basicInfiFragment.getData();
model.setSs(steelFragment.getProductInfo());
model.setAluminium(aluminiumFragment.getProductInfo());
SimpleMultiPartRequest orderRequest = new SimpleMultiPartRequest(Request.Method.POST,
Constance.baseURL + Constance.orderURL, new com.android.volley.Response.Listener<String>() {
#Override
public void onResponse(String response) {
DialogUtil.hideProgrss();
ProductModel mResponse = new Gson().fromJson(response, ProductModel.class);
if (mResponse.getStatus().equalsIgnoreCase(Constance.success)) {
Toast.makeText(getContext(), mResponse.getMessage(), Toast.LENGTH_SHORT).show();
Intent intent = new Intent(getContext(), MainActivity.class);
getContext().startActivity(intent);
getActivity().finish();
} else {
SnackUtil.mackText(mBinding.layoutRoot, mResponse.getMessage(), true);
}
L.e(response);
}
}, new com.android.volley.Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
L.e(error.toString());
DialogUtil.hideProgrss();
DialogUtil.someThingWentWrong(getContext());
}
});
Map<String, String> headerMap = new HashMap<>();
headerMap.put("token", SP.getString(SP.TOKEN));
for (ImageDetails imageDetails : model.getImageList()) {
orderRequest.addStringParam("json", new Gson().toJson(model));
orderRequest.addFile("siteImages",imageDetails.getPath());
orderRequest.addMultipartParam(imageDetails.getName(), getActivity().
getContentResolver().getType(imageDetails.getURI()), imageDetails.getPath());
orderRequest.setHeaders(headerMap);
}
DialogUtil.showProgress(getContext());
RequestQueue requestQueue = Volley.newRequestQueue(getContext());
requestQueue.add(orderRequest);
}
i tried a lot but it is uploading only one image please help me out of these getting stuck since last three days..
SecondFragment.java
public OrderRequestModel getData() {
OrderRequestModel model = new OrderRequestModel();
try {
model.setImageList(imageDetails);
} catch (Exception e) {
SnackUtil.mackText(mBinding.layoutRoot, getString(R.string.some_things_went_wrong), true);
L.e("date parse Error : " + e.getMessage());
}
return model;
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 122:
if (data != null) {
if (resultCode == Activity.RESULT_OK) {
Bitmap image = (Bitmap) data.getExtras().get("data");
String strData = String.valueOf(data.getData());
L.e("Camera : " + strData);
if (image != null) {
ImageDetails imgDetails = new ImageDetails();
imgDetails.setName(MyUtil.getFilename(Uri.parse(strData), getActivity()));
imgDetails.setBitmap(image);
imgDetails.setName("image" + new Random().nextInt(1000));
imageDetails.add(imgDetails);
}
}
adapterImages.notifyDataSetChanged();
}
break;
case 144:
if (data != null) {
if (resultCode == Activity.RESULT_OK) {
String strData = data.getDataString();
Uri[] resultFileChooser = null;
try {
if (data.getClipData() == null) {
L.e("data Clicp is Null");
}
resultFileChooser = new Uri[data.getClipData().getItemCount()];
for (int i = 0; i < data.getClipData().getItemCount(); i++) {
ImageDetails details = new ImageDetails();
details.setPath(getPath(data.getClipData().getItemAt(i).getUri()));
details.setURI(data.getClipData().getItemAt(i).getUri());
details.setName(MyUtil.getFilename(data.getClipData().getItemAt(i).getUri(), getActivity()));
imageDetails.add(details);
L.e("Uri : " + details.getPath());
}
} catch (NullPointerException e) {
if (strData != null) {
resultFileChooser = new Uri[]{Uri.parse(strData)};
ImageDetails imgDetails = new ImageDetails();
imgDetails.setName(MyUtil.getFilename(Uri.parse(strData), getActivity()));
imgDetails.setPath(getPath(Uri.parse(strData)));
imgDetails.setURI(Uri.parse(strData));
imageDetails.add(imgDetails);
L.e("Uri : " + imgDetails.getPath());
}
}
}
adapterImages.notifyDataSetChanged();
}
break;
}
}
this is the code which i am trying i paste my onActivity code and multipart code also.

you may want to enable multi-selection while selection and then syncing with the server.
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setType("image/*");
startActivityForResult(intent, READ_REQUEST_CODE);
you will receive multiple Uri in your onActivity from there use to get file objects and then sync with the server.

Android Fabric Twitter share listener

I use Fabric SDK to send tweets from my application.
I build a share dialog and send tweet from activity.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TwitterAuthConfig authConfig = new TwitterAuthConfig(CONSUMER_KEY, CONSUMER_SECRET);
Fabric.with(this, new TwitterCore(authConfig), new TweetComposer());
Bundle bundle = getIntent().getExtras().getBundle(SHARE_DATA);
String description = bundle.getString(SHARE_DESCRIPTION);
String title = bundle.getString(SHARE_TITLE);
String picture = bundle.getString(SHARE_PICTURE_LINK);
String link = bundle.getString(SHARE_LINK);
TweetComposer.Builder builder = null;
try {
InputStream in = new java.net.URL(picture).openStream();
Bitmap bitmap = BitmapFactory.decodeStream(in);
Uri yourUri = getImageUri(this,bitmap);
builder = new TweetComposer.Builder(this)
.text(title + "\n" + description)
.url(new URL(link))
.image(yourUri);
//??? IS THERE ANY LISTENER ???
builder.show();
} catch (IOException e1) {
e1.printStackTrace();
}
}
I want to know status of sharing, like an success or not, but i can't find any listener for this action. I missed something?

Instead of use builder.show(), you should use builder.createIntent() :
Intent intent = new TweetComposer.Builder(getActivity())
.text("TEXT")
.url("URL")
.createIntent();
startActivityForResult(intent, TWEET_COMPOSER_REQUEST_CODE);
To get the result feedback in onActivityResult() :
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == TWEET_COMPOSER_REQUEST_CODE) {
if(resultCode == Activity.RESULT_OK) {
onTwitterSuccess();
} else if(resultCode == Activity.RESULT_CANCELED) {
onTwitterCancel();
}
}
}

use below method to twitt via rest service and pass media id as null.i m successfully posting tweets from my app
public void postToTwitter(ArrayList<String>mediaIds) {
String message;
if(Validator.isNotNull(preferences.getFbShareMessage())){
message=preferences.getFbShareMessage()+" "+com.aimdek.healthwel.network.Request.HOST_URL + "/user-history/" + userHistory.getUserId() + "/" + userHistory.getId();
}
else {
message = getString(R.string.google_status, HWUtil.getFullName(preferences.getUserInfo().getFirstName(), preferences.getUserInfo().getLastName()), userHistory.getSportName(), HWUtil.secondToTime(userHistory.getDuration()))+" "+com.aimdek.healthwel.network.Request.HOST_URL + "/user-history/" + userHistory.getUserId() + "/" + userHistory.getId();
}
String mediaId;
if (Validator.isNotNull(mediaIds) && mediaIds.size() > 0) {
mediaId="";
for (int i = 0; i < mediaIds.size(); i++) {
if (i == 0) {
mediaId = mediaIds.get(i);
} else {
mediaId += "," + mediaIds.get(i);
}
}
}
else {
mediaId=null;
}
StatusesService statusesService = twitterApiClient.getStatusesService();
statusesService.update(message, null, null, null, null, null, null, null, mediaId, new Callback<Tweet>() {
#Override
public void success(Result<Tweet> result) {
dismissProgressDialog();
if(Validator.isNotNull(preferences.getImagePath()) && !preferences.getImagePath().isEmpty()) {
preferences.getImagePath().clear();
}
com.aimdek.healthwel.network.Request.getRequest().sendRequest(com.aimdek.healthwel.network.Request.SHARE_USER_HISTORY, TwitterIntegration.this, TwitterIntegration.this, RequestParameterBuilder.buildMapForShareUserHistory(userHistory.getId(), TwitterIntegration.this));
}
#Override
public void failure(TwitterException exception) {
if(Validator.isNotNull(preferences.getImagePath()) && !preferences.getImagePath().isEmpty()) {
preferences.getImagePath().clear();
}
dismissProgressDialog();
finish();
HWUtil.showToast(TwitterIntegration.this,exception.getMessage());

Payment to this merchant is not allowed in android while integrating paypal

I am using sandbox account and following the tutorial http://androiddevelopmentanddiscussion.blogspot.com/2014/05/paypal-integration-in-android.html

I am new in this topic so explanation would be nice.

Use your sandbox credential (Client id) here.
