title: Android Facebook SDK 4.0 Login without Facebook App
body: <p>I'm having issues with the webview login for Facebook on Android. </p>
  
  <p>I've followed the tutorials and login works perfectly when the user has the Facebook app installed. When the Facebook app is not installed, the webview for facebook login pops up; however, after logging in and accepting the permissions, the webview simply redirects back to the login screen. It never goes back to my app.</p>
  
  <p>Has anyone else encountered this problem? </p>
  
  <pre><code>    FacebookSdk.sdkInitialize(this);
      profileTracker = new ProfileTracker() {
          @Override
          protected void onCurrentProfileChanged(Profile profile, Profile profile2) {
              if (profile2 != null) {
                  loggedIn(profile2);
              } else {
                  loggedOut();
              }
          }
      };
      accessTokenTracker = new AccessTokenTracker() {
          @Override
          protected void onCurrentAccessTokenChanged(AccessToken accessToken, AccessToken accessToken2) {
              Profile.fetchProfileForCurrentAccessToken();
          }
      };
      callbackManager = CallbackManager.Factory.create();
      LoginManager.getInstance().registerCallback(callbackManager,
              new FacebookCallback&lt;LoginResult&gt;() {
                  @Override
                  public void onSuccess(LoginResult loginResult) {
                      // App code
                      getProfileInfo();
                  }
  
                  @Override
                  public void onCancel() {
                      // App code
                      Log.e("Facebook Login", "Login Cancelled");
                      loggedOut();
                  }
  
                  @Override
                  public void onError(FacebookException exception) {
                      // App code
                      Log.e("Facebook Login", "Failed to Login " + exception.toString());
                      loggedOut();
                  }
              });

  <p>Looking at the logs without filters while the login takes place, I see a couple of possibly relevant logs.</p>
