使用Firebase的Android Facebook登录仅在某些设备上无法使用

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

        </activity>

    </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。
