我正在我的 Android 应用程序上进行 Facebook 集成。它在某些设备上工作正常，但在某些设备上它不工作并给我错误消息：

在此处输入图像描述

下面是代码：

 private UiLifecycleHelper uiHelper;

    private Session.StatusCallback callback = new Session.StatusCallback() {
        @Override
        public void call(Session session, SessionState state, Exception exception) {
            onSessionStateChange(session, state, exception);
        }
    };



    private void onSessionStateChange(Session session, SessionState state, Exception exception) {
        if (   exception instanceof FacebookOperationCanceledException ||
                exception instanceof FacebookAuthorizationException) 
        {
                new AlertDialog.Builder(MainWindow.this)
                    .setTitle("cancel")
                    .setMessage("your permission has expired.")
                    .setPositiveButton("ok", null)
                    .show();

        } 

    }




private void onClickFacebookRequest()

        pendingRequest = savedInstanceState.getBoolean(PENDING_REQUEST_BUNDLE_KEY, pendingRequest);
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);

        outState.putBoolean(PENDING_REQUEST_BUNDLE_KEY, pendingRequest);
    }

谁能告诉我我的代码有什么问题？

此问题通常发生在您手机中的facebook 应用程序未更新时，请更新后检查。它对我有用，希望它也对你有用。

编辑： 要检查哈希键，请将其放入您的onCreate方法中

 PackageInfo info;
try {
    info = getPackageManager().getPackageInfo("com.example.yourpackagename", 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());
}
