Redirect URI doesn't match with the one generated with package name and signature hash.

Why the app always crash and saying that the URI doesn’t match with the one that showing on the AD? I’ve been tried to delete it and make a new one and that not helping either? Is this really a problem with the library either the AD or was that my mistake?

Here the Log:

Process: com.ilhamwahyu.testapp, PID: 10038
    java.lang.IllegalStateException: The redirect URI in the configuration file doesn't match with the one generated with package name and signature hash. Please verify the uri in the config file and your app registration in Azure portal.

This had to be true all along that my Signature Hash was wrong. I follow the steps on Azure Portal but Android Studio gives me an error log. So I come across this. There was a code that I can use to Log the Signature Hash directly from the project.

This is the code.

try {
    info = getPackageManager().getPackageInfo("com.you.name", PackageManager.GET_SIGNATURES);
    for (Signature signature : info.signatures) {
        MessageDigest md;
        md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        String something = new String(Base64.encode(md.digest(), 0));
        //String something = new String(Base64.encodeBytes(md.digest()));
        Log.e("hash key", something);
    }
} catch (NameNotFoundException e1) {
    Log.e("name not found", e1.toString());
} catch (NoSuchAlgorithmException e) {
    Log.e("no such an algorithm", e.toString());
} catch (Exception e) {
    Log.e("exception", e.toString());
}

Finally, I can make the right redirect_uri.

Thank you everyone for helping me out.

As an additional tip: For an APK already pushed to a device, there is a handy tool provided in the MSAL repo here which can export the signature hash of an app installed on a device. You can cross reference this value against your configuration in the application and in the Azure Portal.

Here’s a screenshot of our test app:
