upload video from Android to AWS S3

Question

I added the AWS Android SDK to my app and i have some code in an AsyncTask that should upload my video to my bucket but its not working.

Android code:

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

if (resultCode == RESULT_OK) {
        if (requestCode == SELECT_VIDEO) {

            try {
Uri selectedImageUri = data.getData();
                File file = new File(String.valueOf(selectedImageUri));


                // Initialize the Amazon Cognito credentials provider
                CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
                        getApplicationContext(),
                        "us-east-1:5bfc6b1a-6193-4fXc-823f-ba21a9fadc1b", // Identity Pool ID
                        Regions.US_EAST_1 // Region
                );

                // Create an S3 client
                AmazonS3 s3 = new AmazonS3Client(credentialsProvider);
                // Set the region of your S3 bucket
                s3.setRegion(Region.getRegion(Regions.US_EAST_1));
                TransferUtility transferUtility = new TransferUtility(s3, SellerHomePage.this);

                TransferObserver observer = transferUtility.upload(
                        "willsapptest",
                        "plzWork",
                        file
                );


                observer.setTransferListener(new TransferListener() {
                    public void onStateChanged(int id, TransferState state) {
                        //check the state
                    }

                    @Override
                    public void onProgressChanged(int id, long bytesCurrent, long bytesTotal) {

                    }

                    public void onError(int id, Exception ex) {
                        Log.e("", "Error during upload: " + id, ex);
                    }
                });
        );
                }catch (Exception e){
                SevenSecVideoName = (TextView) findViewById(R.id.SevenSecFileNameTxt);
                SevenSecVideoName.setText("File Name...");
                SevenSecVideoName.setTextColor(Color.parseColor("#797979"));

                e.printStackTrace();
                Toast.makeText(SellerHomePage.this,"Please pick a valid video",Toast.LENGTH_SHORT).show();
            }
        }
    }
}

I have it so unauthenticated users can upload to the S3

Error code from Android Monitor:

Answer 1

You may use it like this

Below code is used to access your aws s3 in which you have to pass accessKey and secretKey as your credentials.

            BasicAWSCredentials credentials = new BasicAWSCredentials(accessKey,secret);
            AmazonS3Client s3 = new AmazonS3Client(credentials);
            s3.setRegion(Region.getRegion(Regions.US_EAST_1));

Transfer utility is the Class from which you can upload your file to s3.

            TransferUtility transferUtility = new TransferUtility(s3, UploadFileActivity.this);

Get the path of your file from your storage and pass it as a file as below

            //You have to pass your file path here.
            File file = new File(filePath);
            if(!file.exists()) {
                Toast.makeText(UploadFileActivity.this, "File Not Found!", Toast.LENGTH_SHORT).show();
                return;
            }
            TransferObserver observer = transferUtility.upload(
                    Config.BUCKETNAME,
                    "video_test.jpg",
                    file
            );

Here you can use observer.setTransferListener to know the progress of your uploading file

            observer.setTransferListener(new TransferListener() {
                @Override
                public void onStateChanged(int id, TransferState state) {

                    if (state.COMPLETED.equals(observer.getState())) {

                        Toast.makeText(UploadFilesActivity.this, "File Upload Complete", Toast.LENGTH_SHORT).show();
                    }
                }

                @Override
                public void onProgressChanged(int id, long bytesCurrent, long bytesTotal) {

                }

                @Override
                public void onError(int id, Exception ex) {

                    Toast.makeText(UploadFilesActivity.this, "" + ex.getMessage(), Toast.LENGTH_SHORT).show();
                }
            });

Answer 2

Your CognitoCachingCredentialsProvider is not initialized correctly. You need to initialize it with the IdentityPoolId which is of the format <region>:<guid>. You currently seem to using the identity pool name.

EDIT:

"wilsapp_MOBILEHUB_1766067928", is the name of the pool it is not the Pool id. To get the pool id go to Cognito console -> click on the name of the pool -> sample code -> copy the pool id from the sample

EDIT2: You will not get exception directly from S3 in your try catch. Instead, You can set Listener to your observer and listen t updates on upload/download

observer.setListener(new TransferListener() {
   public onProgressChanged(int id, long bytesCurrent, long bytesTotal){
     //update progress
   }

   public void onStateChanged(int id, TransferState state) {
     //check the state
   }

   public void onError(int id, Exception ex) {
     //log error
   }
});

It has onError method which returns an exception to track in case there is an exception
