must i change another script in the cloudReco.java?

ok,thankyou

Glad to hear that the issue is solved.

Concerning your second question (how to display image or video instead of book price), my best suggestion is to look at the VideoPlayback sample and trying to combine some of the code there with the CloudReco sample. We don't have a specific tutorial guiding you step-by-step to do that, but we have seen many developers doing the same, so it is definitely doable.

thanks.i dont know the reason i just execute  "ndk-build" now its working fine means when bookcover image scans nothing is showing,but when  flower image scans that time  price is showing,instead of price i need to dispaly some image or vedio,in sample code where they write code for display in price.

Hi, perhaps you just need to wait that the metadata update takes effect.

Also, the content of the mymetadata.txt should be exactly samplebook3.json (for instance avoid any blanks, spaces around it).

Can you then try again ? normally it should just work with your image target too.

Hi i follwed ur link,

and i added one image ,then i  got like this in my clouddatabse 

• Target ID: 2a1346c220e141c9b1cc5b2e6f68b964

and finally i replace the above cleient acees key and secret key in my sample cloud reco app,and i run app,but now also when scan inside media folder bookcover image that time its showing price,if scan my flower image that its not showing any thing,what i did mistake please guide me

okey.  AlessandroB,but in cloudrecognization example sample  specific notes they said package is optional right? and waht ever u said like after clicking "Upload metadata"   then  added "my_metadata.txt".in my case inseide  "my_metadata" file some hello text is there,but where i need to change that my_metadata name to samplebook1.json,and in my code where i want to use that samplebook1.json......thankyou

Hi, if you log into the Target Managaer, and click on your Cloud DB, and you select an Image Target that you have uploaded,

you will see there is a button say "Upload metadata" or  "Metadata package - Change";

if you click on that, you will be able to pass a simple text file;

for instance, you can create a file, call it "my_metadata.txt" (or whatever name you like), edit it with a text editor and type this line into it:

samplebook1.json

Then save the file.

Then you can upload the my_metadata.txt file in the Target Manager using the "Metadata package - Change" button.

Thnkyou for reply.what is metafile in that link. i create  already new database with different images,and in cloud database  client acess and sceret keys i repalced in sample cloud recognization example.... here what  samplebook1.json,in my case what i need to do remain

Hi, have a look att his article, which explains how to use your own Cloud targets with the existing sample:
