Error while deleting a file from amazon s3 bucket

Question

I am trying to delete a file from s3 bucket using AWS SDK android. I have followed the tutorial below to set up my bucket. https://grokonez.com/android/uploaddownload-files-images-amazon-s3-android .

The uploading and downloading work fine. But when I try to delete a file, my application crashes.

Here is the code I am using

BasicAWSCredentials credentials = new BasicAWSCredentials(KEY, SECRET);
AmazonS3Client s3Client = new AmazonS3Client(credentials);
s3Client.deleteObject(bucketName, folderPath);

Answer 1

您应该在后台线程中调用删除对象方法。

new Thread(new Runnable() { @Override public void run() { s3client.deleteObject(new DeleteObjectRequest(AWS_BUCKET, "Path")); } }).start();

Answer 2

您的folderPath变量可能不包含指定存储桶中对象的有效密钥。

Answer 3

You are getting this crash because Android does not let you make a network call from a main thread. You need to wrap this call from a background thread.

new Thread(new Runnable() {
   @Override
   public void run() 
           BasicAWSCredentials credentials = new BasicAWSCredentials(KEY, SECRET);
           AmazonS3Client s3Client = new AmazonS3Client(credentials);
           s3Client.deleteObject(bucketName, folderPath);
   }
}).start();
