使用Firebase的Android Facebook登錄僅在某些設備上無法使用

Question

我已經實現了使用Firebase的Android Facebook登錄，但是它不能在其他設備上使用，只能在我的設備上使用。 我已經在朋友的手機上測試了我的應用程序，但是，facebook登錄不起作用，它只顯示進度對話框，然后什么也沒有。 它甚至沒有崩潰。

有誰知道為什么？？？ 我已經給他寄了我的apk調試程序，我不知道這是否有幫助。

這是我的代碼

有誰知道為什么會這樣嗎？？？ 我是Android開發的新手。

Answer 1

私人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();
}

}

使用此方法並將此密鑰粘貼到Facebook開發人員控制台中。並構建新的apk ..

回答我自己的問題：看來我們必須去找Facebook開發人員，並使我們的應用生效，以使其他用戶登錄。
