Android Facebook Login "LoginActivity could not be started"

Question

I have installed and configure everything for link The Facebook SDK to my Android App.

• Facebook SDK is in my project
• I added my APP ID in the Facebook APP ID
• My Android Key Hash is correct and linked on the board of Facebook Dev
• I have the Activity "com.facebook.FacebookActivity" in my Manifest
• I have the Activity "com.facebook.LoginActivity" in my Manifest
• I have the meta-data facebook_app_id set in my Manifest and correct

The Facebook widget Login set

<com.facebook.login.widget.LoginButton
        android:id="@+id/login_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="30dp"
        android:layout_marginBottom="30dp" />

My Fragment Class

public class FragmentSetting extends  android.support.v4.app.Fragment {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
    SingletonUserData.setCallbackManager(CallbackManager.Factory.create());
}

@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle args) {
    if (!SingletonUserData.isLogged()) {
        view = inflater.inflate(R.layout.fragment_logme, container, false);
        TextView facebook = (TextView) view.findViewById(R.id.LogByFacebook);
        loginButton = (LoginButton) view.findViewById(R.id.login_button);
        loginButton.setReadPermissions(Arrays.asList("public_profile", "user_friends", "email"));
        loginButton.setFragment(this);
        loginButton.registerCallback(SingletonUserData.getCallbackManager(), new FacebookCallback<LoginResult>() {...});

and

    @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    SingletonUserData.getCallbackManager().onActivityResult(requestCode, resultCode, data);
}

After several hours, I can't find the error. Is it because of the Fragment? I tried in my MainActivityToFragment but I have always the same backtrace, which is:

Log in attempt failed: LoginActivity could not be started at com.facebook.login.LoginManager.startLogin(LoginManager.java:382) at com.facebook.login.LoginManager.logInWithReadPermissions(LoginManager.java:250) at com.facebook.login.widget.LoginButton$LoginClickListener.onClick(LoginButton.java:689) at com.facebook.FacebookButtonBase$1.onClick(FacebookButtonBase.java:310)

I was able to solve this by removing LoginActivity from my AndroidManifest.xml

<!--Remove this-->
<activity android:name="com.facebook.LoginActivity" 
android:theme="@android:style/Theme.Translucent.NoTitleBar" 
android:label="@string/app_name" /> 

and adding

<!--Add this-->
<activity android:name="com.facebook.FacebookActivity"
 android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
 android:theme="@android:style/Theme.Translucent.NoTitleBar" 
 android:label="@string/app_name" />
