He estado intentando subir un video que llevé a un grupo de servicios S3 utilizando el SDK de AWS.

Este es el código que tomé del ejemplo de Amazon para la carga de S3. Las únicas cosas que estoy haciendo de manera diferente es:

no creando un nuevo cubo sino reutilizando el que ya está allí.

utilizando un Uri predeterminado para el archivo donde se encuentra la imagen.

public void uploadToS3(View v) {
    AmazonS3Client s3Client = new AmazonS3Client(new BasicAWSCredentials(
        Constants.ACCESS_KEY_ID, Constants.SECRET_KEY));
    String[] filePathColumn = { MediaStore.Images.Media.DATA };
    Cursor cursor = getContentResolver().query(fileUri, filePathColumn,
        null, null, null);
    cursor.moveToFirst();

    int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
    String filePath = cursor.getString(columnIndex);
    cursor.close();

    // Put the image data into S3.
    try {
        //s3Client.createBucket(Constants.getPictureBucket());

        PutObjectRequest por = new PutObjectRequest(
                Constants.getPictureBucket(), Constants.PICTURE_NAME,
                new java.io.File(filePath)); // Content type is determined
                                             // by file extension.
        s3Client.putObject(por);
    } catch (Exception exception) {
        // displayAlert( "Upload Failure", exception.getMessage() );
    }
}

El problema es, una vez que intento crear elAmazonS3Client, la aplicación se bloquea con unnoClassFound excepción.

Aquí está mi Logcat:
