Это мой код:

Button событие, чтобы выбрать изображение из галереи:

public void SelectImage(View view) { 
     Intent galleryIntent = new Intent(Intent.ACTION_PICK, 
       android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
     startActivityForResult(galleryIntent, RESULT_LOAD_IMG); 
    } 

onActivityResult: (исключение появляется во время выполнения последней строки, написанные на этом методе)

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

      // When an Image is picked 
      if (requestCode == RESULT_LOAD_IMG && resultCode == RESULT_OK 
        && null != data) { 
       // Get the Image from data 

       Uri selectedImage = data.getData(); 
       String[] filePathColumn = {MediaStore.Images.Media.DATA}; 
       Cursor cursor = getContentResolver().query(selectedImage, 
         filePathColumn, null, null, null); 
       // Move to first row 
       cursor.moveToFirst(); 
       int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 

       String picturePath = cursor.getString(columnIndex); 
       File f = new File(picturePath); 

       String imageName = f.getName(); 

       AmazonS3Client s3Client = new AmazonS3Client(new BasicAWSCredentials(MY_ACCESS_KEY, MY_SECRET_KEY)); 
       s3Client.setRegion(Region.getRegion(Regions.EU_CENTRAL_1)); 
       PutObjectRequest por = new PutObjectRequest("BUCKET_NAME", FOLDER_NAME+"/"+imageName,f ); 
       s3Client.putObject(por);

Answer 1

Я обнаружил, что загрузка на amazon должна быть другой нитью не в основной теме. Поэтому я добавил класс UploadImage, который расширяет AsyncTask следующим образом:

public class UploadImage extends AsyncTask<String,String,String> { 
    private final String accessKey="my_access_Key"; 
    private final String secretKey="my_secret_key"; 
    private final String bucketName="my_bucket_name"; 
    private final String folderName="Android_Uploads"; /*"Android_Uploads";*/ 
    @Override 
    protected String doInBackground(String... params) { 
     String fileName = params[0]; 
     String filePath = params[1]; 
     AmazonS3Client s3Client = new AmazonS3Client(new BasicAWSCredentials(accessKey,secretKey)); 
     s3Client.setRegion(Region.getRegion(Regions.EU_CENTRAL_1)); 
     PutObjectRequest por = new PutObjectRequest(bucketName, folderName +"/"+ fileName, new File(filePath)); 
     s3Client.putObject(por); 
     return ""; 
    } 
    protected void onPostExecute(String feed) { 

     return ; 
    } 
} 

и я использовал его в onActivityResult в основной деятельности:

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

      // When an Image is picked 
      if (requestCode == RESULT_LOAD_IMG && resultCode == RESULT_OK 
        && null != data) { 
       // Get the Image from data 

       Uri selectedImage = data.getData(); 
       String[] filePathColumn = {MediaStore.Images.Media.DATA}; 
       Cursor cursor = getContentResolver().query(selectedImage, 
         filePathColumn, null, null, null); 
       // Move to first row 
       cursor.moveToFirst(); 
       int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 

       String picturePath = cursor.getString(columnIndex); 
       File f = new File(picturePath); 

       String imageName = f.getName(); 
       new UploadImage().execute(imageName, picturePath);
