Upload an image from Android to Amazon S3?

Question

I need to upload a bitmap to Amazon S3. I have never used S3, and the docs are proving less than helpful as I can\'t see anything to cover this specific requirement. Unfortunate

Answer 1

You can use a library called S3UploadService. First you would need to convert your Bitmap to a File. To do so take a look at this post:

Convert Bitmap to File

S3UploadService is a library that handles uploads to Amazon S3. It provides a service called S3UploadService with a static method where you provide a Context (so the static method can start the service), a File, a boolean indicating if said file should be deleted after upload completion and optionally you can set a callback (Not like an ordinary callback though. The way this works is explained in the README file).

It's an IntentService so the upload will run even if the user kills the app while uploading (because its lifecycle is not attached to the app's lifecycle).

To use this library you just have to declare the service in your manifest:

    ...

    

Then you build an S3BucketData instance and make a call to S3UploadService.upload():

    S3Credentials s3Credentials = new S3Credentials(accessKey, secretKey, sessionToken);
    S3BucketData s3BucketData = new S3BucketData.Builder()
            .setCredentials(s3Credentials)
            .setBucket(bucket)
            .setKey(key)
            .setRegion(region)
            .build();

    S3UploadService.upload(getActivity(), s3BucketData, file, null);

To add this library you need to add the JitPack repo to your root build.gradle:

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

and then add the dependency:

dependencies {
    compile 'com.github.OneCodeLabs:S3UploadService:1.0.0@aar'
}
