Sending SMS using code sends duplicate SMS

I just start android with a small project. I am trying to do the following:
STEP 1. get the response from an url [https://client.itscholarbd.com/getsmsdata]
STEP 2. send sms based on the data received from step 1
STEP 3. DELETE the data which is processed. i.e. sms is sent. this is done by DELETE request with ID
STEP 4. REPEAT from STEP 1.

Everything works like a charm. some data is being processed twice. Suppose. at step 1: we got the following json data:
{"response":[{"id":395,"phone":"01620010950","message":"testing! -
itscholarbd.com","user_id":1},{"id":396,"phone":"01673050495","message":"testing! - itscholarbd.com","user_id":1}]}
Then id: 395 is processed twice. I struggle with such problem for 2 days. at last I post here for any idea. Thanks in advance.

I guess that the problem is by calling jsonParse() again in your deleteFromDB(...) method:
private void deleteFromDB(int id) {
.......
.......
#Override
public void onResponse(String response) {
Log.i("resonse", response);
//here, I guess this is the problem
jsonParse();
}
......
......
}

And I am getting bellow message in logcat
java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String com.dgdev.mtmicds.DbAccess.Remote.UserRegistrationModel.getStatus()' on a null object reference
at com.dgdev.mtmicds.ProfileFragment$3.onResponse(ProfileFragment.java:105)
Please Help me...I am a newbie...

Try this
#Override
public void onResponse(Call<UserRegistrationModel> call, Response<UserRegistrationModel> response) {
if(response.isSuccessful()) {
UserRegistrationModel res = response.body();
if(res!=null) {
Toast.makeText(view.getContext(), res.getStatus(), Toast.LENGTH_LONG).show();
} else {
Toast.makeText(view.getContext(), "Didn't get response", Toast.LENGTH_LONG).show();
}
}
}

Your com.dgdev.mtmicds.DbAccess.Remote.UserRegistrationModel is null. Check whether it is being alloted any value by getting in debug mode. Run the code step by step in debug mode and check how it is getting initialized.
Hint: Check this line of your code in debugger:
UserRegistrationModel res = response.body();

After clicking on the button, it is redirecting to the twitter login page and after clicking on "connect" button, it simply returns to the fragment and doesn't show the Toast message. When I Click the button for the second time, it shows toast from failure method.

just add in your activity

super.onActivityResult(requestCode, resultCode, data);
yourcurrentfragment.onActivityResult(requestCode, resultCode, data);

Search all .pdf files present in the Android device

How can I search all .pdf and .doc files present in the Android device through a programmatic way?

Try using the below code. This will work for you.
public void walkdir(File dir) {
String pdfPattern = ".pdf";
File listFile[] = dir.listFiles();
if (listFile != null) {
for (int i = 0; i < listFile.length; i++) {
if (listFile[i].isDirectory()) {
walkdir(listFile[i]);
} else {
if (listFile[i].getName().endsWith(pdfPattern)){
//Do whatever you want
}
}
}
}
}
To search on the whole SD card, call this function using:
walkdir(Environment.getExternalStorageDirectory());

Have a look at File, list.
Basically, get a starting Directory, call "list" with a filter(FilenameFilter), and then traverse sub directories. I am not sure if there is a one function that does all this for you.

Have a look at Stack Overflow question How can I get all audio files from the SD card on Android?.
Change the extension of the file like if you want all PDF files then extension ".pdf". Use this to get all PDF files from the device.

I found this method in my old project. This function will get you the PDF file and its information.
ManageFIleInfoForRecycler is my custom class to store the file information.
"storage" passes as "external".
public ArrayList<ManageFIleInfoForRecycler> fileList(String storage) {
ArrayList< ManageFIleInfoForRecycler > fileInfo = new ArrayList<>();
// Can give any file type, "doc", "pdf", etc.
String pdf = MimeTypeMap.getSingleton().getMimeTypeFromExtension("pdf");
int j = 0;
Uri table = MediaStore.Files.getContentUri(storage);
// Column
String[] column = {MediaStore.Files.FileColumns.DATA, MediaStore.Files.FileColumns.TITLE};
// Where
String where = MediaStore.Files.FileColumns.MIME_TYPE + "=?";
String[] args = new String[]{pdf};
Cursor fileCursor = getApplicationContext().getContentResolver().query(table, column, where, args, null);
String [] filesLists = new String[]{};
while (fileCursor.moveToNext()) {
int pathString = fileCursor.getColumnIndex(MediaStore.Files.FileColumns.DATA);
int nameIndex = fileCursor.getColumnIndex(MediaStore.Files.FileColumns.TITLE);
String path = fileCursor.getString(pathString);
String name = fileCursor.getString(nameIndex);
ManageFIleInfoForRecycler temp = new ManageFIleInfoForRecycler();
temp.filePath = path;
temp.fileName = name;
fileInfo.add(temp);
}
return fileInfo;
}
