In this tutorial we will see how we can upload image to server using Retrofit in Android Studio. To upload image we have to use multipart/form-data. Multipart sends a single object(file) in divided in multiple parts, each part is separated by a boundary and has some portion of object’s data. Each part also has its own headers like Content-Type, Content-Deposition.
In this tutorial we use Retrofit as network library, as it has built in support for multipart. We will go through the following steps in this tutorial:
1. Add Dependencies to Gradle
2. Create Retrofit Instance
3. Create Upload API
4. Upload the Image
