Facebook错误：允许键：在dev.facebook android配置你的app键哈希[复制]

参见英文答案 > This app has no Android Key hashes configured. – Login with Facebook SDK                                    3个
当我运行我的Facebook应用程序时,我收到以下错误.允许密钥.在http://developers.facebook.com/apps/178779105632639配置您的应用密钥哈希值…

任何的想法？

解决方法:

看来你生成的hashkey不正确.您可以从以下代码生成应用程序哈希键.试试吧

public static void showHashKey(Context context) {
    try {
        PackageInfo info = context.getPackageManager().getPackageInfo(
                "com.example.project", PackageManager.GET_SIGNATURES); //Your package name here
        for (Signature signature : info.signatures) {
            MessageDigest md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            Log.v("KeyHash:", Base64.encodetoString(md.digest(), Base64.DEFAULT));
            }
    } catch (NameNotFoundException e) {
    } catch (NoSuchAlgorithmException e) {
    }
}
