This issue exists from ancient times and prevents us from using sdk as a library and avoid patching it (as it's done now for 1.7.* based code).

Problem is when S3 object is encrypted using default encryption method using this symmetric key algorithm (and in case of AWS SDK for Android it's RSA):

this is the fix for that particular problem:
src/com/amazonaws/services/s3/internal/crypto/EncryptionUtils.java:

Method:
private static SecretKey getDecryptedSymmetricKey(byte[] encryptedSymmetricKeyBytes, EncryptionMaterials materials, Provider cryptoProvider) {

        byte[] decryptedSymmetricKeyBytes = cipher.doFinal(encryptedSymmetricKeyBytes);

•        // Here is where Amazon SDK hits us with bug. If RSA algorithm is used for encryption of symmetric key,
  

•        // it will skip leading zero bytes (1/256 chance for first byte in the key to be zero,
  

•        // 1/65536 for second to be zero, etc. We should restore it or we won't be able
  

•        // to decrypt the key and hence the file itself
  

•        // http://www.bouncycastle.org/wiki/display/JA1/Frequently+Asked+Questions#FrequentlyAskedQuestions-4.WhenIencryptsomethingwithRSAIamlosingleadingzerobytesoffmydata,whyareyouguysshippingsuchabrokenimplementation?
  

•        int shift = 32 - decryptedSymmetricKeyBytes.length;
  

•        if (shift > 0) {
  

•            byte[] recoveredDecryptedSymmetricKeyBytes = new byte[32];
  

•            for (int i = shift; i < 32; i++) {
  

•                recoveredDecryptedSymmetricKeyBytes[i] = decryptedSymmetricKeyBytes[i - shift];
  

•            }
  

•            decryptedSymmetricKeyBytes = recoveredDecryptedSymmetricKeyBytes;
  

•        }
      return new SecretKeySpec(decryptedSymmetricKeyBytes, JceEncryptionConstants.SYMMETRIC_KEY_ALGORITHM);
  

The same fix should be done in AWS JAVA SDK: https://github.com/aws/aws-sdk-java/blob/master/aws-java-sdk-s3/src/main/java/com/amazonaws/services/s3/internal/crypto/EncryptionUtils.java

Hi, I am having an intermittent issue when I try to upload a set of images to a S3 bucket. Basically my application tries to upload a set of 40 – 50 images. But in middle of the process the SDK shows this error repeatedly. I have noted that it happens in newer android versions 4.4 or higher, but in 4.0 and 4.2 it doesn’t happen.

Hi,

I've been trying to integrate my application with AWS Analytics, I was able to successfully authenticate with cognito, and also get an instance of the MobileAnalyticsManager... BUT when my activity pauses, and eventClient attempts to submitEvents... my application crashes.

The stacktrace I'm getting, but I'm not quite sure if it's related... it's the following:

07-01 16:39:59.177 23841-27327/? I/AmazonHttpClient﹕ Unable to execute HTTP request: null

How can I get this solved ?

Thanks!

EDIT: This was issued while running an AVD with API 21, haven't tried on a real device.

so. I can't resume download.

Feature Request:

Currently SDK provides feature to get the preSignedURL.
But we also need that the SDK should provide a way to generate authentication header.

That will enable these secure URL's to be downloaded and cached easily with all the image cache libraries available for example picasso, ion, UIL etc.

Thanks

Hi,
Amazon S3 SDK (v2.1.4) is successfully providing signed URL

URL url = sS3Client.generatePresignedUrl("<BUCKET_NAME>", "<FILENAME>", nowPlus10Minutes.getTime());

But when I use that URL to fetch the image through HTTPURLConnection there is an security error for certificate. (FYI I am using picasso for downloading the image, that's where HTTPURLConnectionc comes in scene)

And when I try the URL in chrome I had the same problem
*Server could not prove that its security certificate from .s3.amazon.com

Altough in browser one can add the hosts in exception and by doing that I am able to download the Image through chrome.

Please let me know why this is happening, Am I missing someting ?

Thanks
Rahul

We can authenticate with Cognito using Digits and upload images; however, after about 30 to 40 minutes of just having the app sit there, we get an error saying we can't access it when trying to upload a new image. Seen below:

com.amazonaws.services.cognitoidentity.model.NotAuthorizedException: Access to Identity 'us-east-1:NotTheActualPoolId' is forbidden. (Service: AmazonCognitoIdentity; Status Code: 400; Error Code: NotAuthorizedException; Request ID: 96d61bb5-3553-11e5-ae36-8be8ef351d5f)

The second time we try to upload the image, immediately after the first error, we get:

Unauthenticated access is not supported for this identity pool. (Service: AmazonCognitoIdentity; Status Code: 400; Error Code: NotAuthorizedException; Request ID: a9b498c2-3557-11e5-be30-5b1603ee422d)

It looks like the first error clears our credentials and the second makes sense since we don't have credentials anymore and we have unauthenticated access turned off in Cognito.

Any ideas?

Hi,

Do you know how can i generate a signedURL for consuming private S3 content served through CloudFront? i cant seem to find any information on this.
I can generate signedURL from S3 and consume the files from there, but doing this through CloudFront seems impossible.
Thanks

I am facing the problem to write the column in AWS table.The API which writes the columns in AWS is not found in the current AWS library.I am using the AWS SDK 2.2.2, I have found the link similar to my problem but there solution not working with me.I have attached the screenshots of the error and the documentation of AWS.
Also, following is the stackoverflow link.

http://stackoverflow.com/questions/21933724/aws-dynamodb-tutorial-does-not-import-certain-classes

The v1 repo contained a POM file to facilitate building and resolution of dependencies. Can you do the same for v2?

Please, introduce support for the new region: http://aws.amazon.com/blogs/aws/aws-region-germany/

Any idea how to solve this?

I am trying to upload item from Android client to China bucket. It is ~20 seconds video (~50mb) with hight resolution. It is separated in multiple chunks and each of them successfully uploaded:

• I receive ProgressEvent.PART_COMPLETED_EVENT_CODE for all of them
• I track how much bytes are transfered and it fully reach the size of the video

When I receive the last ProgressEvent.PART_COMPLETED_EVENT_CODE SDK stops send any events codes -- looks like it done his job. I checked the data on the server but got an error "NoSuchKey"

Observed behaviour:
SDK doesn't return ProgressEvent.COMPLETED_EVENT_CODE. Amazon via web request returns "NoSuchKey" error

Expected behaviour:
SDK returns ProgressEvent.COMPLETED_EVENT_CODE. Amazon via web request returns uploaded video.

Environment:
Nexus 5, Android 5.1
AWS SDK 2.2.2
Region "cn-north-1"

I am using amazon s3 android low level sdk to upload a file and want to set md5 checksum to upload data.

1)Following is the code to create credentials:

BasicAWSCredentials lAwsCredentials = new BasicAWSCredentials(
Constants.ACCESS_KEY_ID, Constants.SECRET_KEY);

AmazonS3Client lS3Client = new AmazonS3Client(lAwsCredentials);

2)Following is the code to calculate md5

public class MD5CheckSum {

public static byte[] createChecksum(String pFilepath) throws Exception {
InputStream lFis = new FileInputStream(pFilepath);

byte[] lBuffer = new byte[1024];
MessageDigest lMessageDigest = MessageDigest.getInstance("MD5");

int lNumRead;

do {
    lNumRead = lFis.read(lBuffer);
    if (lNumRead > 0) {
        lMessageDigest.update(lBuffer, 0, lNumRead);
    }
} while (lNumRead != -1);

lFis.close();
return lMessageDigest.digest();

}

public static String getMD5Checksum(String pFilepath) throws Exception {
byte[] lBytes = createChecksum(pFilepath);
return Base64.encodeToString(lBytes, Base64.DEFAULT);
}
}

3)Following is the code to set md5 using metadata:

try {
lMd5 = MD5CheckSum.getMD5Checksum(pFile.getAbsolutePath());

    Log.v(TAG, "CheckSum:====" + lMd5);
} catch (Exception lException) {
    lException.printStackTrace();
}

ObjectMetadata lObjectMetadata = new ObjectMetadata();
if (lMd5 != null) {
    lObjectMetadata.setContentMD5(lMd5);

lObjectMetadata);
But a exception is thrown by amazon when i set md5:

Caused by: com.amazonaws.services.s3.model.AmazonS3Exception: Anonymous users cannot initiate multipart uploads. Please authenticate. (Service: Amazon S3; Status Code: 403; Error Code: AccessDenied; Request ID: BA0C68FC884703FD), S3 Extended Request ID: re2sdbzf8MMqGAyrNQOoqYJ8EdXERoWE7cjG+UpfAtFuP5IeAbXmk6Riw+PX8Uw3Jcspn1rSQvI=

Is this the correct way to set md5?

Note: When md5 is not set(ie objectmetadata is not set) then upload works without any exception

Reference issue: #12

At download end i am getting md5 null.
Following is the code i am using to get md5 .Please let me know if it is correct way:

GetObjectMetadataRequest lGetObjectMetadataRequest = new GetObjectMetadataRequest(
mBucket, mKey);

ObjectMetadata lObjectMetadata = mS3Client
.getObjectMetadata(lGetObjectMetadataRequest);

    if (lObjectMetadata != null)
        Log.v(TAG, "Checksum:" + lObjectMetadata.getContentMD5());

According to the http://aws.amazon.com/releasenotes/0908276529378471 one of the changes is: Replacing Jackson with Gson 2.2.4 in the core runtime library. The file size is reduced to 1.3Mb and the total number of methods is down to 7.5k. Improve the performance of unmarshalling Json responses.

However, jackson-core-2.1.1.jar is still part of the SDK binary release and it's used in the https://github.com/aws/aws-sdk-android/blob/master/src/main/java/com/amazonaws/util/json/JacksonFactory.java

Should it be removed?

Aws Android v 2.0.5

Maybe adding in the shutdown javadoc of that it needs to be called in a separate thread?

The SDK does not set Accept-Encoding: gzip, deflate when performing request, the result is that when there is lot of text the SDK:

• is much slower (a request can take 30 seconds instead of 3 seconds)
• consume more battery
• consume more data plan

do we have to use any other plugin or software to use these packages? can anyone tell me in detail how to use these packages.

My app have some google functionality like GCM,Google +,Google map with clustering.
Before implementing aws my app working well in all devices.
But after implementing aws my app stop working in non-google devices means app only work in Nexus device.
I tried lots but not found any solution.
But We have checked more and founded that there are some issue with aws-android-sdk-core-2.2.1 because this file contain some google classes so it may be conflict with other google classes.

Any one have idea why this issue comes ?

Looks like after rework in 2.1.9 those 3 files are no longer needed:

Hi,

I just upgrade the android SDK to version 2.2.0, but unable to upload file to S3. Downloading and deleting file works, but uploading always has the exception below. We are using TransferManager and unauthenticated Cognito to connect to S3.

Previous version works, not sure any changes we need to be aware of when upgrading to 2.2.0?

Thanks

Would it be possible to abstract the HTTP logic?
Being able to choose between different HTTP client like Apache HttpClient or OkHTTP would be great.

Removing HttpClient would save ~900k in our APK and plenty of methods count. It would also have the advantages to use a more up to date HttpClient.

I am just tired of juggling versions and classes, please give me a hint how to use S3 upload.

Hi,

In our app, I copied aws-android-sdk-2.1.1-core.jar and aws-android-sdk-2.1.1-s3.jar in to my libs folder. The app uses Jackson library to parse Json, but it is already included in the AWS SDK jar file. It seems that the sdk reduces the methods inside the Jackson libs, hence when I tried to compile my app, I got many errors:

"cannot find symbol method readValue"
"cannot find symbol method writeValue"
"cannot find symbol method writeValueAsString"

I then try to add 3 Jackson jars into my project libs folder but it still fails. I also tried to add Jackson using Gradle, but still see above error.

Do you have any idea to make it work? Thanks

Best,
Thomas

I cannot decide when to update the sdk because I don't know what change

I upload my file to aws service from android. I configured it like this:

`   AwsMetadata awsMetadata = resultData.getParcelable(Params.CommandMessage.EXTRA_MESSAGE);
    AWSCredentials awsCredentials = new BasicAWSCredentials(
            awsMetadata.getAccountId(),
            awsMetadata.getSecretKey()
    );
    // set up region
    TransferManager transferManager = new TransferManager(awsCredentials);
    Region region = Region.getRegion(Regions.fromName(awsMetadata.getRegionEndpoint()));
    transferManager.getAmazonS3Client().setRegion(region);


    final MediaItem mediaItem = datasource.get(0);
    Log.d(App.TAG, "File is exists: "
            + mediaItem.getContentUri() + " "
            + new File(mediaItem.getContentUri()).exists());

    // prepare file for upload
    PutObjectRequest putObjectRequest = new PutObjectRequest(
            awsMetadata.getBucketName(),
            awsMetadata.getSecretKey(),
            new File(mediaItem.getContentUri())
    );


    Log.d(App.TAG, "Total data: " + mediaItem.getSize());
    Upload upload = transferManager.upload(putObjectRequest, new S3ProgressListener() {

        private int totalTransfered = 0;

        @Override
        public void onPersistableTransfer(PersistableTransfer persistableTransfer) {
        }

        @Override
        public void progressChanged(ProgressEvent progressEvent) {

            Log.d(App.TAG, "Bytes are transferred: " + progressEvent.getBytesTransferred());
            totalTransfered += progressEvent.getBytesTransferred();
            long totalSize = mediaItem.getSize();
            Log.d(App.TAG, "Total transferred: " + ((totalTransfered / totalSize) * 100) + " percent");
        }
    });

Amazon SDK uses it's own client and it should be configured properly from the box.

What is the reason for this behaviour?

p.s.
I must note this application are developing in China, it means it uses "cn-north-1" region

Hello,

I am trying to build the source code available from here (https://github.com/aws/aws-sdk-android) rather than using jar files due to some reasons. I have added all the necessary third party libraries .

build.gradle

dependencies {
    compile files('libs/sjsxp.jar')
    compile files('libs/commons-codec-1.3.jar')
    compile files('libs/commons-logging-1.1.1.jar')
    compile files('libs/httpclient-4.2.3.jar')
    compile files('libs/httpcore-4.2.jar')

    compile files('libs/joda-time-2.2.jar')
    compile files('libs/jaxp-api-1.4.2.jar')
}

When building the project, I got the following error:

Also, latest aws sdk version is 2.1.7 but source code at github is 2.1.1 . Is it possible to get the latest aws android sdk source code ?

Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
(com.amazonaws.javax.xml.stream.xerces.util.SecuritySupport12$4) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is not an inner class.

On Android 5.0 when trying to use S3 to upload, I am receiving an SSLHandshakeException. The exact same code works on 4.4 (KitKat) and below. When using 2.0.5, I get an exception; however, when using 2.1.5 I get a native error and it crashes complaining about libcrypt.so.

I found this URL to be interesting with regards to the matter:

We're currently trying to integrate Cognito using developer authenticated identities using the following example:
https://mobile.awsblog.com/post/Tx3E3NJURV1LNV1/Integrating-Amazon-Cognito-using-developer-authenticated-identities-An-end-to-en

We can successfully receive data from Cognito after authentication, but the problem is that when we restart the application, SDK resets the identity to null for some reason and we need to perform authentication process once again (add an entry to logins hashmap, request token, etc).

It seems like sdk has correct sessionCredentials during the same launch when authentication happened, but loses them on restart. saveCredentials method in CognitoCachingCredentialsProvider is not being called, so I assume credentials are not cached or something like that. I don't know if sessionCredentials are to be obtained from SharedPreferences at all times so I'm not sure this is what causes the problem.

We have tried to use developer authenticated identities in CognitoSyncDemo project from aws-sdk-android-samples and it behaves the same way when implemented there.

Thanks!

Is it possible to connect to Amazon using fixed IP instead address?

We are working on a device which uses android and has a mobile GPRS modem (Sierra or Gemalto) and using SQS and S3 APIs to communicate with Amazon. When we use the wifi it works fine, but when we use the GPRS modem we get issues with DNS resolving.

Is there any way we can fix the IP for S3 and SQS we want to communicate?
Thanks

Please, update the source code to match with newest release.

Hello, What is the proper way to obtain a file's url after an upload?

Hi,

I'm testing newest release 2.1.2, and when trying to upload file to S3, I got this exception:

javax.net.ssl.SSLException: hostname in certificate didn't match: <com.myappname.debug.s3.amazonaws.com> != <*.s3.amazonaws.com> OR <*.s3.amazonaws.com> OR <s3.amazonaws.com>

It worked in 2.1.1. Pls let me know if you need more detail, thanks

The request handler definition files are missing. I can find the "request.handler" files in the official releases at http://aws.amazon.com/mobile/sdk/, but they do not appear in a fresh build from the Github repository.

Hi,

Android has the weird limitation that they only allow 64K methods on an apk. This SDK already uses too many methods because the third party libraries (apache common, jackson, joda time) are huge, so when I compile a normal app, I will get this error:

Unable to execute dex: method ID not in [0, 0xffff]: 65536
Conversion to Dalvik format failed: Unable to execute dex: method ID not in [0, 0xffff]: 65536

Since you are rewriting the SDK, is it possible to eliminate dependencies on these libraries? I know for date time, date4j is pretty good replacement with tiny size compared to Joda, and very easy to migrate to it. I hope there's alternative to apache common too, that library is huge but not always useful to be included.

Hi i am using aws android sdk for uploading images to my bucket on the server it is running fine, but How can we upload Pdf/word files to my bucket , please anyone guide me with demo ?

How to include aws-android-sdk via gradle,

Please let us know how we can do that.

Thanks

Hi there,

Overall the new S3 Transfer Utility seems great!
I'm currently trying to upgrade our application to make use of the new API, but it seems the threading was not correctly implemented. I'm getting the following error when I try to upload a file :
Can't create handler inside thread that has not called Looper.prepare()

It comes from the Handler() creation here :

Hi there,

For Low level api:
I am using low level api for multipart upload .When i kill the app and try to resume upload it doesnot resume instead it restarts .When i try resume the upload i am getting different upload id for same key and bucket.
When tried to store the upload id obtain when i start upload and try to used that upload id first time upload resumed but it did not complete.I got following error exception:

We are using video uploading functionality in android and ios.
Both have same function for uploading but in android it taken more time compare to ios
and that is meaning less.
Can you please any solution for this issue ?

I was wondering why is Gson repackaged and included in core instead of being declared as simple outside dependency which user would add themselves?

I am personally using Gson 2.2.4 in my Android project too, it's sad my project now include Gson twice.
