Facebook的登录后不会再回来，但再次询问登录 [英] Facebook after login not coming back but asking login again
问题描述
我想在我的应用程序来实现Facebook登录的功能，并给予出版许可后，得到令牌。
I am trying to implement Facebook login functionality in my app and getting token after giving publish permission.
有关这一点，我按照下面的步骤。
For this I follow following steps.
-
在创建Facebook应用程序（填补像应用程序的名称，散列键（释放），类名，包名，单点登录的所有详细信息）
Create app on Facebook(Fill all details like app name, Hash key(Release), Class name, Package Name, Single Sign On)
应用程序适用于所有的用户了。
App is available for all user now.
一切工作正常与我，如果原生的Facebook应用程序是安装在我的手机。但是，如果本机应用程序没有安装那么它将填充登录信息就问我点击确定按钮再次要求我登录后授权后打开Facebook的web视图。而这一过程将继续。
Everything is working fine with me if Native Facebook app is install on my mobile. But if native app is not install then it will open facebook webview after filling login info it ask me to authorize after clicking on ok button it again asking me to login. And this process will continue.
*的的登录，并允许应用程序的权限它不回来我的屏幕，但它要求登录我再的* 之后。
*After login and allowing app permission it's not coming back to my screen but it asking login me again*.
下面是我的屏幕截图。
Here is my screen shot.
下面是第二个截屏
点击OK，然后之后它再次要求我登录。这是循环登录 - 批准─登录..
这里是我的全code：
After clicking on ok then it's asking me again to login. It's loop login - authorize- login..
Here is my full code:
我用我自己的按钮，所以我不添加XML code。
I am using my own button so i am not adding xml code.
public class FBActivity extends Activity {

}
@Override
protected void onSaveInstanceState(Bundle outState) {
// TODO Save current session
super.onSaveInstanceState(outState);
Session session = Session.getActiveSession();
Session.saveSession(session, outState);
}
}
我也越来越哈希键..这里是code哈希键
I also getting hash key.. Here is code for hash key
private void printHashKey() {
try {
PackageInfo info = getPackageManager().getPackageInfo(
"com.myapp",
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 (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}
}
在的AndroidManifest.xml
我还添加上网权限和元数据为Facebook。
I also add Internet Permission in AndroidManifest.xml and meta-data for Facebook .
希望所有这些信息就足够了，如果需要任何东西必然会有更多的更新我的问题。
Hope all this information is sufficient if need any thing more will surely update my question.
请给我任何参考或暗示。
Please give me any reference or hint.

u需要一个图书馆的 easyfacebookandroidsdk.jar ，并建立它在乌拉圭回合的项目
u need a library easyfacebookandroidsdk.jar and build it up in ur project
使用code：
public class MainActivity extends Activity implements LoginListener{
EditText et1;
private FBLoginManager fbLoginManager;
Button b;
//replace it with your own Facebook App ID
public final String FacebookTesting="218874471621782";

connectToFacebook();

public void connectToFacebook(){

}
}
让你的Facebook应用程序ID和放大器;在code更换。我总是用code每当我有张贴在FB中的文本。
Get your Facebook App id & replace it in the code. I always use this code whenever i have to post the text on FB.
在清单中给予上网权限
＆LT;使用-权限的Android：名称=android.permission.INTERNET对/＆GT;
In manifest give Internet permission
<uses-permission android:name="android.permission.INTERNET"/>
这就是所有
干杯
