I have two apps, one is a trial version the other the full version of a game, both made with adobe air. While saving data via the sharedobjects solution is no problem, I would like to use "one" savegame for both appsm, so users can keep their progress when upgrading to the full version. I tried around a little. But code like e.g. ...:
SharedObject.getLocal("myApp","/");
... doesnt work. So the question is, is there a way to have two Air apps using the same shared object? Or maybe if not using, at least "read" the shared object of another Air app?
Thanks in advance,
ANB_Seth
The answer is yes, I actually made a game transfer system for iOS and Android via network connection and 6 digit hash the user has to enter in the newly installed app to fetch the SO from the server. You could do this with a simple file stored locally on the SD card or other local storage device.
/**
* send this user's current save data to the server
*/
public function send():void{
var ba:ByteArray = new ByteArray();
// Main.sv.user - is the registerClassAlias object we write/read locally via SharedObject
ba.writeObject(Main.sv.user);
var name:String = Crypto.hash("Random Secrect Salt - typically user score, name, etc.");
// create 6 digit hash
var key:String = Crypto.hash(name).slice(0, 6).toUpperCase();
var request:URLRequest = new URLRequest ( 'https://sharedobject.com/transfer/save/name/'+name+'/key/'+key );
var loader: URLLoader = new URLLoader();
request.contentType = 'application/octet-stream';
request.method = URLRequestMethod.POST;
request.data = ba;
loader.addEventListener(IOErrorEvent.IO_ERROR, function (evt:Event) {
trace("error - network");
onSaveRestoreEvent(1);
});
loader.addEventListener(Event.COMPLETE, function (evt:Event) {
addChild(new BaseDialog("Save Sent To Server", "Your data has been sent to the server. To get this data back from the server " +
"you will need your secret key. Please write this six digit key down:\n"+name));
});
loader.load( request );
}
/**

public function receive():void{
var text:Sprite = new Sprite();
var textInput:TextInput = new TextInput();
textInput.width = Constants.SCREEN_WIDTH-100;
textInput.y = -50;
text.addChild(textInput);
var dialog:BaseDialog = new BaseDialog("Enter Secret Save Key", "Please enter your six digit secret save key in the field below, then press \"Get\".\n\n",
"Get", function():void{
text.removeChildren();
var url:String = "https://sharedobject.com/transfer/get/name/"+textInput.text; //servlet url
var request:URLRequest = new URLRequest(url);
//get rid of the cache issue:
var urlVariables:URLVariables = new URLVariables();
urlVariables.nocache = new Date().getTime();
request.data = urlVariables;
request.method = URLRequestMethod.GET;
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.BINARY;
loader.addEventListener(Event.COMPLETE, function (evt:Event) {

I'm wiriting my application in Android, but i don't know how to send response only to device whos generated session with special ID in express-session. For example, i have 3 phones and click at the same time button login with difference data in pools, all 3 devices captured the same object instead of 3 different destined ( first response object from express was caught by 3 devices rest 2 object ignored, i want to sent object every one of them ).
....
var express = require('express');
var session = require('express-session');
var crypto = require('crypto');
var uuid = require('node-uuid');
var app = express();
app.use(session({
secret: 'DFGDFG',
resave: false,
saveUninitialized:false,
genid:function(req){
return crypto.createHash('sha256').update(uuid.v1()).update(crypto.randomBytes(256)).digest("hex");
},
}));
app.post('/login', (request,response)=> {
var post_data = request.body;
request.session.user = post_data.user;
request.session.password = post_data.password;
if(err){
console.log("error");
}
else{
var db= client.db('test');
db.collection('object').findOne({'user':request.session.user}, function(error,user){
if(user.password == request.session.password){
request.session.amount = user.amount; // if password was correct, sending amount account
console.log('Success');
res.send(request.session.amount);
}
else{
console.log('Password invalid');
}
}
});
So I have been working on a product (Android First and then iOS) for a long time that index faces of people using AWS Rekognition and when they are again scanned later, it identifies them.
It's working great when I index a face from an Android device and then try to search it with an Android device. But if I try to search it later on iOS app, it doesn't find it. Same is the result if I go other way round. Index with iOS, search with Android, not found.
The collection ID is same while indexing and searching on both devices. I couldn't figure out how is it possible that a face indexed by one OS type, same region, same collection, couldn't be found while on other device.
If anyone here could try and help me with the issue, please do. I'll be really thankful.
Update 1: I have called "listCollections" function on both iOS and android apps. Both of them are showing different list of collections. This is the issue. But I can't figure our why it is happening. The identity pool and region is same on both of them.
Here is my Android Code to access Rekognition:
mCredentialsProvider = new CognitoCachingCredentialsProvider(
mContext,
"us-east-2:xbxfxexf-x5x5-xax7-x9xf-x5x0xexfx1xb", // Identity pool ID
Regions.US_EAST_2 // Region
);
mUUID = UUID.randomUUID().toString().replace("-", "");
mAmazonS3Client = new AmazonS3Client(mCredentialsProvider);
mAmazonS3Client.setRegion(Region.getRegion(Regions.US_EAST_2));
mAmazonRekognitionClient = new AmazonRekognitionClient(mCredentialsProvider);
if(!mAmazonS3Client.doesBucketExist(mFacesBucket)) {
mAmazonS3Client.createBucket(mFacesBucket);
}
Log.i(TAG, "Uploading image to S3 Bucket");
mAmazonS3Client.putObject(mFacesBucket, getS3ObjectName(), new File(data[0].toString()));
Log.i(TAG, "Image Uploaded");
Image image = new Image();
try {
image.setBytes(ByteBuffer.wrap(Files.toByteArray(new File(data[0].toString()))));
} catch (IOException e) {
e.printStackTrace();
}
Log.i(TAG, "Indexing image");
IndexFacesRequest indexFacesRequest =new IndexFacesRequest()
.withCollectionId(mFacesCollection)
.withImage(image)
.withExternalImageId(mUUID)
.withDetectionAttributes("ALL");
mAmazonRekognitionClient.indexFaces(indexFacesRequest);
Here is my iOS code to access Rekognition:
func uploadToCollection(img: UIImage)
{
let myIdentityPoolId="us-east-2:xbxfxexf-x5x5-xax7-x9xf-x5x0xexfx1xb"
let credentialsProvider = AWSCognitoCredentialsProvider(regionType: .USEast2, identityPoolId: myIdentityPoolId)
//store photo in s3()
let configuration = AWSServiceConfiguration(region: .USEast2, credentialsProvider: credentialsProvider)
AWSServiceManager.default().defaultServiceConfiguration = configuration
rekognitionClient = AWSRekognition.default()
guard let request = AWSRekognitionIndexFacesRequest() else
{
puts("Unable to initialize AWSRekognitionindexFaceRequest.")
return
}
var go=false
request.collectionId = "i_faces" + self.firebaseID.lowercased() //here iosCollection will be replaced by firebase Current UserID
request.detectionAttributes = ["ALL", "DEFAULT"]
request.externalImageId = self.UUID //this should be mUUID, passed as parameter to this function
let sourceImage = img
let image = AWSRekognitionImage()
image!.bytes = sourceImage.jpegData(compressionQuality: 0.7)
request.image = image
self.rekognitionClient.indexFaces(request) { (response:AWSRekognitionIndexFacesResponse?, error:Error?) in
if error == nil
{
print("Upload to Collection Complete")
}
go=true
return
}
while(go==false){}
}
Create a collection and added images to the collection and create an index. I suspect few things in your setup and code.
1) The Identity Pool Id, AWS Region used across iOS and Android
2) The name of the collection used (pay attention to the delimiters used in the collection name)
Android:
CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(appContext, "MyPoolID", Regions.US_EAST_1);
public void searchFacesByImage() {
Image source = new Image().withS3Object(new S3Object().withBucket("us-east-1-bucket").withName("ms.jpg"));
Image ms2 = new Image().withS3Object(new S3Object().withBucket("us-east-1-bucket").withName("ms-2.jpg"));
Image ms3 = new Image().withS3Object(new S3Object().withBucket("us-east-1-bucket").withName("ms-3.jpg"));
Image ms4 = new Image().withS3Object(new S3Object().withBucket("us-east-1-bucket").withName("ms-4.jpg"));
String collectionId = "MyCollectionID";
AmazonRekognitionClient client = new AmazonRekognitionClient(credentialsProvider);
try {
System.out.println("Creating collection: " + collectionId );
CreateCollectionRequest request = new CreateCollectionRequest().withCollectionId(collectionId);
CreateCollectionResult createCollectionResult = client.createCollection(request);
System.out.println("CollectionArn : " + createCollectionResult.getCollectionArn());
System.out.println("Status code : " + createCollectionResult.getStatusCode().toString());
} catch (Exception ex) {
ex.printStackTrace();
}
IndexFacesRequest indexFacesRequest = new IndexFacesRequest();
indexFacesRequest.setImage(source);
indexFacesRequest.setCollectionId(collectionId);
client.indexFaces(indexFacesRequest);
indexFacesRequest = new IndexFacesRequest();
indexFacesRequest.setImage(ms2);
indexFacesRequest.setCollectionId(collectionId);
client.indexFaces(indexFacesRequest);
indexFacesRequest = new IndexFacesRequest();
indexFacesRequest.setImage(ms4);
indexFacesRequest.setCollectionId(collectionId);
client.indexFaces(indexFacesRequest);
SearchFacesByImageRequest searchFacesByImageRequest = new SearchFacesByImageRequest();
searchFacesByImageRequest
.withCollectionId(collectionId)
.withImage(ms3)
.withFaceMatchThreshold(80F);
SearchFacesByImageResult searchFacesByImageResult =
client.searchFacesByImage(searchFacesByImageRequest);
List <FaceMatch> faceImageMatches = searchFacesByImageResult.getFaceMatches();
for (FaceMatch face: faceImageMatches) {
Log.d(TAG, face.toString());
}
}
iOS:
Create the Cognito Credentials Provider
AWSCognitoCredentialsProvider *credentialsProvider = [[AWSCognitoCredentialsProvider alloc] initWithRegionType:AWSRegionUSEast1 identityPoolId: #"MyPoolID"];
AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionUSEast1 credentialsProvider:credentialsProvider];
[AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;
Use the same Identity Pool Id and Region (us-east-1).
func faceIndexNoFacesSearch() {
let rekognition = AWSRekognition.default()
let faceRequest = AWSRekognitionSearchFacesByImageRequest()
do {
let image = AWSRekognitionImage()

rekognition.searchFaces(byImage: faceRequest!).continueWith { (response) -> Any? in

Ok so the problem turned out to be much different and solution was rather very simple. I posted another question regarding the same problem when I found it was a bit different and I have posted an answer as well.
Here it is:

If anyone have this issue, i solved it by using small bufferSize, i set it to 100KB,
i found it is attempt to close the connection before all data is sent when the buffer is big.
You can add event OutputProgressEvent.OUTPUT_PROGRESS to check the number of bytes that has been written in the dataChannelConnection.
I'm trying to upload a simple text file to ftp, the code works on the pc.
On android the app connects successfully to the ftp but when I try to upload the file I get "2031:Error #2031: Socket Error."

As the title states, my user's on iOS and Android are reporting their save data has been deleted when I push an update to the respected storefronts. The game saves and restores data properly on application load and exit. I have not changed any save information locations or package names... Just mere bug fixes, build, push.
Any clarification would be helpful, or proposed redundant data backup scheme's I should pursue to ensure the end-user experience is from henceforth not affected negatively. I would also like to understand better how I can test this as a release package is not allowed to update a market installed application.
var so:SharedObject = SharedObject.getLocal("storage");
var u:User;
if(so.data != null){
u = so.data.user;
}
trace("Loading application...");
if(u != null){
trace("LOADING SAVE DATA");
user = u;
}else{
trace("NO SAVE DATA EXISTS");
user = new User();
}
I have discovered the cause of this issue and it seems that Adobe has identified and fixed the issue as well (as of AIR 3.5). https://bugbase.adobe.com/index.cfm?event=bug&id=3347676
SharedObjects are stored within a directory named according to the SWF used by your application, so if your application is running off "myApp.swf" the SharedObject will be stored in a directory "myApp". If you change the name of this SWF (i.e. the corresponding XML build sheet configuration file for your AIR project) any subsequent builds will store their SharedObjects in a new location.
The issue described in this bug was specifically denoted for iOS, wherein the application was not storing the SharedObject in the corresponding SWF location as described above but in a separate location denoted by the "filename" attribute in your project's XML build sheet.
I have also discovered that Adobe does indeed condone the use of a SharedObject for persistent storage on a mobile platform.
I have developed a simple backup for future version save redundancy in case future updates fail to persist the SharedObject.
