我想實現Facebook集成到我的Android應用程序,它會關閉並登錄到Facebook罰款,但是當它試圖傳遞訪問令牌迴應用程序它只是返回:Android上的Facebook集成fbconnect斷開的鏈接
該網頁在fbconnect://成功#=的access_token [訪問令牌] 可能暫時無法連接,或者它已永久性地移動到新的 網址。
很明顯,其中[ACCESS TOKEN]
是一個很長的字符序列。
我已經得到了正確的App ID,並將密鑰哈希添加到了Facebook。但是我可以錯過什麼過程?
代碼:
public class FacebookActivity extends Activity {
private static final String APP_ID = "[MY APP ID]";
private static final String[] PERMISSIONS = new String[] {"publish_stream"};
private static final String TOKEN = "access_token";
private static final String EXPIRES = "expires_in";
private static final String KEY = "facebook-credentials";
private Facebook facebook;
private String messageToPost;
public boolean saveCredentials(Facebook facebook) {
Editor editor = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE).edit();
editor.putString(TOKEN, facebook.getAccessToken());
editor.putLong(EXPIRES, facebook.getAccessExpires());
return editor.commit();
}
public boolean restoreCredentials(Facebook facebook) {
SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE);
facebook.setAccessToken(sharedPreferences.getString(TOKEN, null));
facebook.setAccessExpires(sharedPreferences.getLong(EXPIRES, 0));
return facebook.isSessionValid();
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
facebook = new Facebook();
restoreCredentials(facebook);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_facebook);
String facebookMessage = getIntent().getStringExtra("facebookMessage");
if (facebookMessage == null){
facebookMessage = "Test wall post";
}
messageToPost = facebookMessage;
if (! facebook.isSessionValid()) {
loginAndPostToWall();
}
else {
postToWall(messageToPost);
}
}
public void loginAndPostToWall(){
facebook.authorize(this, APP_ID, PERMISSIONS, new LoginDialogListener());
}
public void postToWall(String message){
Bundle parameters = new Bundle();
parameters.putString("message", message);
parameters.putString("description", "topic share");
try {
facebook.request("me");
String response = facebook.request("me/feed", parameters, "POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("") ||
response.equals("false")) {
showToast("Blank response.");
}
else {
showToast("Message posted to your facebook wall!");
}
finish();
} catch (Exception e) {
showToast("Failed to post to wall!");
e.printStackTrace();
finish();
}
}
class LoginDialogListener implements DialogListener {
@Override
public void onComplete(Bundle values) {
saveCredentials(facebook);
if (messageToPost != null){
postToWall(messageToPost);
}
}
public void onFacebookError(FacebookError error) {
showToast("Authentication with Facebook failed!");
finish();
}
public void onError(DialogError error) {
showToast("Authentication with Facebook failed!");
finish();
}
public void onCancel() {
showToast("Authentication with Facebook cancelled!");
finish();
}
}
private void showToast(String message){
Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show();
}
}
新Android開發,所以我敢肯定,這是簡單的東西。
你的問題是什麼?您無法發佈消息 – TNR
那麼這是最終目標,但問題是,當Facebook嘗試使用訪問令牌重定向回我的應用程序時,它會顯示上述消息。 (網頁無法顯示)。因此,我的應用程序無法獲得訪問令牌,因此永遠無法獲得授權。 – anothershrubery
是您的應用程序去facebook應用程序,然後它不提供令牌或nt給你令牌,當你直接從你的應用程序登錄 –
