I have tried for several days to solve this problem, using the Dungeons demo code that comes with the SDK. I've tried to Google for an answer but can't find one.
- In the Dungeons demo, I passed my public key from the dev console.
- Signed the apk and uploaded to console without publish.
- Testing for both
android.test.purchased& product list created on console with published for subscription (The main feature I want for my app).
But still I get an error of Signature verification failed and then the signature does not match data. How can I solve this?
public static ArrayList<VerifiedPurchase> verifyPurchase(String signedData, String signature)
{
if (signedData == null) {
Log.e(TAG, "data is null");
return null;
}
if (Consts.DEBUG) {
Log.i(TAG, "signedData: " + signedData);
}
boolean verified = false;
if (!TextUtils.isEmpty(signature)) {
String base64EncodedPublicKey = "MIIBIjA....AQAB";
PublicKey key = Security.generatePublicKey(base64EncodedPublicKey);
verified = Security.verify(key, signedData, signature);
if (!verified) {
Log.w(TAG, "signature does not match data.");
return null;
}
}
}
public static boolean verify(PublicKey publicKey, String signedData, String signature)
{
if (Consts.DEBUG) {
Log.i(TAG, "signature: " + signature);
}
Signature sig;
try {
sig = Signature.getInstance(SIGNATURE_ALGORITHM);
sig.initVerify(publicKey);
sig.update(signedData.getBytes());
if (!sig.verify(Base64.decode(signature))) {
Log.e(TAG, "Signature verification failed.");
return false;
}
return true;
} catch (NoSuchAlgorithmException e) {
Log.e(TAG, "NoSuchAlgorithmException.");
} catch (InvalidKeyException e) {
Log.e(TAG, "Invalid key specification.");
} catch (SignatureException e) {
Log.e(TAG, "Signature exception.");
} catch (Base64DecoderException e) {
Log.e(TAG, "Base64 decoding failed.");
}
return false;
}
