findViewById(R.id.buttonSubmitimg1).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
ContentResolver contentResolver = getContentResolver();
try {
img1 = MediaStore.Images.Media.getBitmap(contentResolver, imageUriFront);

            } catch (IOException e) {
                throw new RuntimeException(e);
            }


            String uid="20";

userDocument.setUid(uid);

            Log.d("SubmitCompleteInfo", "RequestBody: " +(imgtostring(img1)));
            userDocument.setFirstImagePath(imgtostring(img1));

            userDocument.setFirstImageName("first_image_" + uid + ".jpg");


            informationUserViewModel.sendDocumentImg1(userDocument);
            informationUserViewModel.getResponseLiveData().observe(DocumentInfo.this, response -> {
                try {
                   
                    JSONObject jsonResponse = new JSONObject(response);
                    String status = jsonResponse.getString("status");

                    if (status.equals("ok")) {
                        Toast.makeText(DocumentInfo.this, "اطلاعات ثبت شد.", Toast.LENGTH_SHORT).show();




                    } else {
                        // دریافت پیام خطا از پاسخ
                        String errorMessage = jsonResponse.optString("message", "خطا در ثبت اطلاعات");
                        Toast.makeText(DocumentInfo.this, errorMessage, Toast.LENGTH_SHORT).show();

    return encodeImage;
}

and i send my request to server by volley
