Android Retrofit 2ファイルのアップロードが機能していません

ファイルをアップロードするアプリを開発したいと思います。私はソースコードを手に入れました。しかし、それは画像のためだけに働いています。また、2 MB以下のサイズの画像ファイルしかアップロードできません。私はすべてのタイプのファイルをアップロードしたいと思います。私を助けてください。私のコードは以下の通りです。Android Retrofit 2ファイルのアップロードが機能していません

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()); 
        } 
       }); 

      } 
     }); 
    } 
} 

}

2メガバイト以上のzipファイルをアップロードする際にエラーが表示されます。
