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
here is my code to upload image to Amazon AWS S3 bucket Hope this is helpful for you First let me clear some key points you can either take image from camera or pick image from gallery ,AWS store images as a file so first thing you need to store image to local dir and get path of image then create a file from that path after this you will be able to upload that imagefile to AWS.
first you need to add configration on Oncreate
BasicAWSCredentials credentials = new BasicAWSCredentials(KEY,SECRET);
s3 = new AmazonS3Client(credentials);
s3.setRegion(Region.getRegion(Regions.US_EAST_1));
private void uploadFile() {
verifyStoragePermissions(CustomCameraActivity.this);
TransferUtility transferUtility =
TransferUtility.builder()
.context(getApplicationContext())
.awsConfiguration(AWSMobileClient.getInstance().getConfiguration())
.s3Client(s3)
.build();
TransferObserver uploadObserver= null;
File file2 = FileUtils.getFile(CustomCameraActivity.this, storageImagePath);//here i am converting path to file ,,FileUtils.getFile is custom class
uploadObserver = transferUtility.upload("your bucket name", imageNameWithoutExtension + ".jpg", file2);// imagenamewithoutExtension is actually the name that you want to store
uploadObserver.setTransferListener(new TransferListener() {
@Override
public void onStateChanged(int id, TransferState state) {
if (TransferState.COMPLETED == state) {
Toast.makeText(getApplicationContext(), "Upload Completed!", Toast.LENGTH_SHORT).show();
uploadResourcesApi(uploadResoucesURL);
//imageFile.delete();
//file2.delete();
} else if (TransferState.FAILED == state) {
//imageFile.delete();
//file2.delete();
}
}
@Override
public void onProgressChanged(int id, long bytesCurrent, long bytesTotal) {
float percentDonef = ((float) bytesCurrent / (float) bytesTotal) * 100;
int percentDone = (int) percentDonef;
//tvFileName.setText("ID:" + id + "|bytesCurrent: " + bytesCurrent + "|bytesTotal: " + bytesTotal + "|" + percentDone + "%");
}
@Override
public void onError(int id, Exception ex) {
ex.printStackTrace();
}
});

Take a look at the Amazon S3 API documentation to get a feel for what can and can't be done with Amazon S3. Note that there are two APIs, a simpler REST API and a more-involved SOAP API.
You can write your own code to make HTTP requests to interact with the REST API, or use a SOAP library to consume the SOAP API. All of the Amazon services have these standard API endpoints (REST, SOAP) and in theory you can write a client in any programming language!
Fortunately for Android developers, Amazon have released a (Beta) SDK that does all of this work for you. There's a Getting Started guide and Javadocs too. With this SDK you should be able to integrate S3 with your application in a matter of hours.
The Getting Started guide comes with a full sample and shows how to supply the required credentials.
Conceptually, Amazon S3 stores data in Buckets where a bucket contains Objects. Generally you'll use one bucket per application, and add as many objects as you like. S3 doesn't support or have any concept of folders, but you can put slashes (/) in your object names.
you can use the below mentioned class to Upload data to amazon s3 buckets.

We can directly use "Amazone s3" bucket for storing any type of file on server, and we did not need to send any of file to Api server it will reduce the request time.
Gradle File :-
compile 'com.amazonaws:aws-android-sdk-core:2.2.+'
compile 'com.amazonaws:aws-android-sdk-s3:2.2.+'
compile 'com.amazonaws:aws-android-sdk-ddb:2.2.+'
Manifest File :-
<service android:name="com.amazonaws.mobileconnectors.s3.transferutility.TransferService"
android:enabled="true" />
FileUploader Function in any Class :-
private void setUPAmazon() {
//we Need Identity Pool ID like :- "us-east-1:f224****************8"
CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(getActivity(),
"us-east-1:f224****************8", Regions.US_EAST_1);
AmazonS3 s3 = new AmazonS3Client(credentialsProvider);
final TransferUtility transferUtility = new TransferUtility(s3, getActivity());
final File file = new File(mCameraUri.getPath());
final TransferObserver observer = transferUtility.upload(GeneralValues.AMAZON_BUCKET, file.getName(), file, CannedAccessControlList.PublicRead);
observer.setTransferListener(new TransferListener() {
@Override
public void onStateChanged(int id, TransferState state) {
Log.e("onStateChanged", id + state.name());
if (state == TransferState.COMPLETED) {
String url = "https://"+GeneralValues.AMAZON_BUCKET+".s3.amazonaws.com/" + observer.getKey();
Log.e("URL :,", url);
//we just need to share this File url with Api service request.
}
}
@Override
public void onProgressChanged(int id, long bytesCurrent, long bytesTotal) {
}
@Override
public void onError(int id, Exception ex) {
Toast.makeText(getActivity(), "Unable to Upload", Toast.LENGTH_SHORT).show();
ex.printStackTrace();
}
});
}
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:
<application
...>
...
<service
android:name="com.onecode.s3.service.S3UploadService"
android:exported="false" />
</application>
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'
}
