Android Facebook Login with Firebase does not work in some devices only mine

Question

I've implemented Android Facebook Login With Firebase however it does not work in different devices, it only works on mine. I've tested my app on a friend's mobile, however, facebook login did not work, it only showed progress dialog and then nothing. It didn't even crash.

Does anyone know why??? i've sent him my apk-debug, i dont know if it makes difference.

This is my code

    </application>

    <uses-permission android:name="android.permission.INTERNET"/>

</manifest>

Does anyone know why this happens??? I'm quite newbie to Android development.

Answer 1

private void PrintHashKey() {

try {
    PackageInfo info = getPackageManager().getPackageInfo(
            "-----------PUT YOUR PACKAGE NAME ------------",
            PackageManager.GET_SIGNATURES);
    for (Signature signature : info.signatures) {
        MessageDigest md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
    }
} catch (PackageManager.NameNotFoundException e) {
    e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
    e.printStackTrace();
}

}

Use this method and paste this key in facebook developer console.. and build new apk ..

回答我自己的问题：看来我们必须去找Facebook开发人员，并使我们的应用生效，以使其他用户登录。
