Android Retrofit 2 file upload is not working

Question

I want to develop an app which is upload any type of file to sever. I got source code. But it is working only for images. And only upload below 2 MB size of image files. I want to upload all type of files. Please help me. My codes are shown below.

MainActivity.java

public class MainActivity extends AppCompatActivity {
Service service;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Button btn = (Button) findViewById(R.id.btn_upload);

    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();

    // Change base URL to your upload server URL.
    service = new Retrofit.Builder().baseUrl("http://192.168.1.4/work/filesharing/").client(client).build().create(Service.class);

    if (btn != null) {
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                String filePath1 = "/storage/emulated/0/gt.png";

                File file = new File(filePath1);

                RequestBody reqFile = RequestBody.create(MediaType.parse("*/*"), file);
                MultipartBody.Part body = MultipartBody.Part.createFormData("uploaded_file", file.getName(), reqFile);
                RequestBody name = RequestBody.create(MediaType.parse("text/plain"), "upload_test");



                retrofit2.Call<okhttp3.ResponseBody> req = service.postImage(body, name);
                req.enqueue(new Callback<ResponseBody>() {
                    @Override
                    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) { }

                    @Override
                    public void onFailure(Call<ResponseBody> call, Throwable t) {
                        t.printStackTrace();

                        Log.d("failure", "message = " + t.getMessage());
                        Log.d("failure", "cause = " + t.getCause());
                    }
                });

            }
        });
    }
}

}

Error will showing when upload the zip file above 2MB.

Answer 1

I got the answer. It is the problem in xampp server. Now i can send large files. I got the answer from this link How to Increase Import Size Limit in phpMyAdmin using Xampp server?

But the speed is low. Any way it's working as fine.

Answer 2

Please reduce the logging level or remove it all together

Have a look at JakeWharton reply on this link https://github.com/square/retrofit/issues/540

"By calling .setLogLevel(RestAdapter.LogLevel.FULL) you are forcing Retrofit to buffer the entire request body into memory so that it can log. That's what the call to readBodyToBytesIfNecessary in the stack trace is doing.

Enabling logging like this should only be done when debugging."

Answer 3

Its related to this issue https://github.com/square/retrofit/issues/540 . You can disable your interceptor Level.BODY. It can be working for all type files, did you tried with other type files?

Answer 4

You can refer from here too https://futurestud.io/tutorials/retrofit-2-how-to-upload-files-to-server it will help upload the files

Answer 5

I had the same problem uploading large images or videos. The main problem is you're using body level in HttpLoggingInterceptor, and logger is printing your file in logcat triggering a java.lang.OutOfMemoryError exception.

If you don't want to disable the body level loggin you can add this code to avoid loggin to print big large files content. I created my own HttpLoggingInterceptor and add an if condition to skip body loggin in case of content-length > 10Ks.

HttpLoggingInterceptor is a final class, so you can't override it. You can make a copy of HttpLoggingInterceptor file and replace this original code:

if (!logBody || !hasRequestBody) {
            logger.log("--> END " + request.method());
        } else if (bodyEncoded(request.headers())) {
            logger.log("--> END " + request.method() + " (encoded body omitted)");
        } else {
            Buffer buffer = new Buffer();
            requestBody.writeTo(buffer);
            //[...]

with this code:

if (!logBody || !hasRequestBody) {
            logger.log("--> END " + request.method());
        } else if (bodyEncoded(request.headers())) {
            logger.log("--> END " + request.method() + " (encoded body omitted)");
        } else if (requestBody.contentLength()>1024 * 10) { //>10Kb
            logger.log("--> END " + request.method() + " (contentLength > 10Kb --> omitted)");
        } else {
            Buffer buffer = new Buffer();
            requestBody.writeTo(buffer);
            //[...]

I hope this can help anyone. And sorry for my English ;).

Answer 6

I had the same issue But I found There is no issue in the library. My issue is resolved. Its Server side issue. You Might check following point to resolve it:-

1. Check how lengthy file can be uploaded to the server.
2. Check server connection time out from the server point of view.
3. Make sure you have to change the file size on Apache server also. (In my case php filesize of apache server was 5MB)
