Simpl3r ======= Amazon S3 multipart file upload for Android, made simple  This library provides a simple high level Android API for robust and resumable multipart file uploads using the Amazon S3 service. All the complexity of file chunking, resuming, entity tag caching and interaction with Amazon's S3 API is abstracted from the developer. This library manages synchronous file part uploads only. Part uploads performed in parallel are generally not suitable for mobile bandwidths. Usage ----- Uploads can be initiated as follows: ```java AmazonS3Client s3Client = new AmazonS3Client( new BasicAWSCredentials(YOUR_S3_ACCESS_KEY, YOUR_S3_SECRET)); File file = new File("path/to/some.file"); String s3Key = file.getPath(); // create a new uploader for this file Uploader uploader = new Uploader(this, s3Client, YOUR_S3_BUCKETNAME, s3Key, file); // register listener for upload progress updates uploader.setProgressListener(new UploadProgressListener() { @Override public void progressChanged(ProgressEvent progressEvent, long bytesUploaded, int percentUploaded) { // broadcast/notify ... } }); // initiate the upload String urlLocation = uploader.start(); ``` Subsequent `Uploader` instances or calls to `start()` using the same `s3key` will attempt to resume the upload from the beginning of the last part that was uploaded successfully. A `SharedPreferences` instance for the supplied `Context` is used to cache the part ETags, or you can supply your own. You can also supply your own part size to the `Uploader`, but note that the minimum for the S3 API is 5 megabytes. This project contains a working example project which more fully demonstrates its usage. Dependencies ------------ This library depends upon the [AWS SDK for Android](http://aws.amazon.com/sdkforandroid/), specifically the following components: * `aws-android-sdk-<VERSION>-core.jar` * `aws-android-sdk-<VERSION>-s3.jar` Building -------- Run `ant jar` from the project directory or simply download a pre-built version from the `builds` directory of this GitHub repository.
