Using AWS SDK For Android

If you want to implement file upload to AWS S3 as part of your Android app here are some tips to get you going.

Setup

1. Download the Android-AWS SDK
2. Unzip the downloaded package then go to the lib folder
3. In the lib folder copy aws-android-sdk-[version]-core.jar and aws-android-sdk-[version]-s3.jar
4. Use the mechanism your IDE has provided add these jar files and make it available in code. (For Android Studio 0.5.4, I manually added it to the app > lib folder and right clicked on the jar files and select Make Module

Coding

// Create a new S3Client with your credentials. You could get the Keys from the IAM console.
AmazonS3Client s3Client =

new AmazonS3Client(new BasicAWSCredentials("ACCESS KEY", "SECRET KEY");

// Create a PutObjectRequest. This is used to communicate with AWS and upload your file
// The KEY is the full file path to where your file should be stored on AWS.
// For example, images/category/subcategory/image_name.jpg
// The FILE is a file object that you want to upload
PutObjectRequest putObjectRequest = new PutObjectRequest("BUCKET", "KEY", "FILE");

// Now tell AWS S3 a that you want to upload an image with the specifications above.
s3Client.putObject(putObjectRequest);
