How to Compress the captured image file size before sending to server using retrofit

Question

I am Using Retrofit retrofit:2.1.0' to upload file image to server

If I take image using front camera image get uploaded successfully but if take back side camera its not uploaded i think because of large file size image not uploaded is there any option to compress the file size before sending to server in retrofit?

File Sending Coding

  map.put("complaint_category", RequestBody.create(parse("text"), caty_id_str.getBytes()));

    // Map is used to multipart the file using okhttp3.RequestBody
    File file = new File(Config.uriImage);
    // Parsing any Media type file
    RequestBody requestBody = RequestBody.create(parse("*/*"), file);
    MultipartBody.Part fileToUpload = MultipartBody.Part.createFormData("photo", file.getName(), requestBody);
    RequestBody filename = RequestBody.create(parse("text/plain"), file.getName());

    Call<PostComplaint> call3 = apiInterface.postComplaint(fileToUpload, filename, map);
    call3.enqueue(new Callback<PostComplaint>() {
        @Override
        public void onResponse(Call<PostComplaint> call, Response<PostComplaint> response) {

            progressDoalog.dismiss();

            PostComplaint respon = response.body();

            PostComplaint.Response respo = respon.getResponse();

            String result = respo.getResult();
            String data = respo.getData();
            if (result.equalsIgnoreCase("Success")) {

                Toast.makeText(getApplicationContext(), data, Toast.LENGTH_SHORT).show();
                Intent intent = new Intent(Activity_Post_Complaint.this, MainActivity.class);
                startActivity(intent);

            } else {

                Toast.makeText(getApplicationContext(), data, Toast.LENGTH_SHORT).show();
            }

        }

        @Override
        public void onFailure(Call<PostComplaint> call, Throwable t) {
            progressDoalog.dismiss();
            Log.d("Error", "" + t.getMessage());
            call.cancel();
        }


    });

API Interface

@Multipart
@POST("/somelink.php?")
Call<PostComplaint> postComplaint(@Part MultipartBody.Part file,
                               @Part("photo") RequestBody name,
                               @PartMap Map<String, RequestBody> fields);

APIClient.java

public class APIClient {

    private static Retrofit retrofit = null;

    static Retrofit getClient() {

        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor)
                .connectTimeout(60, TimeUnit.SECONDS)
                .readTimeout(60, TimeUnit.SECONDS)
                .writeTimeout(60, TimeUnit.SECONDS)
                .build();

        retrofit = new Retrofit.Builder()
                .baseUrl("http://192.168.1.135")
                .addConverterFactory(GsonConverterFactory.create())
                .client(client)
                .build();

        return retrofit;
    }

Try

int compressionRatio = 2; //1 == originalImage, 2 = 50% compression, 4=25% compress
File file = new File (imageUrl);
try {
    Bitmap bitmap = BitmapFactory.decodeFile (file.getPath ());
    bitmap.compress (Bitmap.CompressFormat.JPEG, compressionRatio, new FileOutputStream (file));
}
catch (Throwable t) {
    Log.e("ERROR", "Error compressing file." + t.toString ());
    t.printStackTrace ();
}

Thank you so much it worked but image quality very poor. – sangavi Apr 14 '17 at 11:16
What value of compressionRatio you used? – PEHLAJ Apr 14 '17 at 11:17

now i used ratio 25 its working fine thank you so much you saved my time. – sangavi Apr 14 '17 at 11:48

@Pehlaj I'm using retrofit as well, your code final result is Bitmap how to use it with RequestBody ? ( RequestBody don't accept Bitmap ) – Mohammed Riyadh Jan 22 '18 at 16:44
@AliAdil You have to convert bitmap to base64 string and then use that string with Request body. https://stackoverflow.com/questions/9224056/android-bitmap-to-base64-string#answer-9224180 – PEHLAJ Jan 23 '18 at 04:39
pls check with the ratio – Swapnil Kshirsagar Nov 03 '18 at 11:30

If you are looking for image compression, you may use this library https://github.com/zetbaitsu/Compressor . It is pretty much simple and awesome. The link explains it all.

you can using from ImageZipper for image compression, you can change its size and quality

Add this to your root build.gradle file:

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

Add this to your app module's build.gradle file:

implementation 'com.github.amanjeetsingh150:ImageZipper:1.3'

Custom Compressor :

 File imageZipperFile=new ImageZipper(MainActivity.this)
                    .setQuality(50)
                    .setMaxWidth(300)
                    .setMaxHeight(300)
                    .compressToFile(actualFile);

   RequestBody requestBody = RequestBody.create(MediaType.parse("*/*"), imageZipperFile);
                MultipartBody.Part fileToUpload = MultipartBody.Part.createFormData("file", URLEncoder.encode(imageZipperFile.getName(), "utf-8"), requestBody);
                RequestBody filename = RequestBody.create(MediaType.parse("text/plain"), Hawk.get("auth_email").toString());
                Call<ResponseModel> call = service.fileUpload(filename,fileToUpload);

OK Now Get Bitmap!!

 Bitmap b=new ImageZipper(MainActivity.this).compressToBitmap(actualFile);

try following code:

Bitmap bmp = BitmapFactory.decodeFile(file);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bmp.compress(CompressFormat.JPEG, 70, bos);
InputStream in = new ByteArrayInputStream(bos.toByteArray());
ContentBody foto = new InputStreamBody(in, "image/jpeg", "filename");

Sending compressed capture image to server with text

Capture Image:

public void captureImage() {

    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    try {

        path = createImageFile();

        file = FileProvider.getUriForFile(MainActivity.this,
                BuildConfig.APPLICATION_ID + ".provider", path);

    } catch (IOException e) {

    }

    List<ResolveInfo> resInfoList = context.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
    for (ResolveInfo resolveInfo : resInfoList) {
        String packageName = resolveInfo.activityInfo.packageName;
        context.grantUriPermission(packageName, file, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
    }

    intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, file);
    startActivityForResult(intent, REQUEST_TAKE_PHOTO);
}

onActivityResult:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_TAKE_PHOTO) {
        if (resultCode == RESULT_OK) {

            Config.uriImage = String.valueOf(path);

            Toast.makeText(getApplicationContext(), Config.uriImage, Toast.LENGTH_SHORT).show();
        }
    }
}

Create Path:

    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";

            ".jpg",         /* suffix */
            storageDir      /* directory */
