How to detect an CTS approved Android build? -

-

in documentation of android n preview mentioned:

this build not compatibility test suite (cts) approved. apps depend on cts approved builds won’t work (android pay example).

in android app want check whether device/build cts approved on first launch. possible? how android pay it?

the safetynet api allows run compatibility check which:

allows app check if device running matches profile of device has passed android compatibility testing. compatibility check creates device profile gathering information device hardware , software characteristics, including platform build.

once have connected googleapiclient using safetynet.api, can call

byte[] nonce = getrequestnonce(); // should @ least 16 bytes in length. safetynet.safetynetapi.attest(mgoogleapiclient, nonce) .setresultcallback(new resultcallback<safetynetapi.attestationresult>() {   @override   public void onresult(safetynetapi.attestationresult result) {     status status = result.getstatus();     if (status.issuccess()) {       // indicates communication service successful.       // result.getjwsresult() contains result data     } else {       // error occurred while communicating service     }   } });

and parse response per the instructions, looking "ctsprofilematch": true in resulting json.
