Erreur lors spec.setContent (intention) sur tabSpace

Question

Il y a une erreur alors que je suis en train intention comme spec.setContent(Intent); sur tabSpace, et il fonctionne très bien si je mets une disposition sur spec.setContent(tab1);

Et suivant est l'erreur: -

did you forget to call 'public void setup(localactivitymanager activitygroup)

Voici la classe: -

public class test extends AppCompatActivity { 

    Point size; 
    RelativeLayout r1; 
    CallbackManager callbackManager; 
    Context context; 
    TabHost.TabSpec spec_signin,spec_signup; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     requestWindowFeature(Window.FEATURE_NO_TITLE); 
     getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 
     setContentView(R.layout.main); 

     context = getApplicationContext(); 

     Display display = getWindowManager().getDefaultDisplay(); 
     size = new Point(); 
     display.getSize(size); 
     Bitmap bmp = Bitmap.createScaledBitmap(BitmapFactory.decodeResource(
       getResources(),R.drawable.accont_bannre),size.x,size.y,true); 
     Drawable dr = new BitmapDrawable(bmp); 
     r1 = (RelativeLayout)findViewById(R.id.r1); 
     r1.setBackgroundDrawable(dr); 

     TabHost host = (TabHost)this.findViewById(R.id.tabhost); 
     host.setup(); 

     //Tab 1 
     spec_signin = host.newTabSpec("SIGNIN"); 
     Intent songsIntent = new Intent(this, NotificationActivity.class); 
     spec_signin.setContent(songsIntent); 
     spec_signin.setIndicator("SIGN IN", getResources().getDrawable(R.drawable.active_arrow)); 
     // spec_signin.setIndicator("SIGNIN"); 
     host.addTab(spec_signin); 

     //Tab 2 
     spec_signup = host.newTabSpec("SIGNUP"); 
     Intent Intent = new Intent(this, NotificationActivity.class); 
     spec_signup.setContent(Intent); 
     spec_signup.setIndicator("SIGN UP", getResources().getDrawable(R.drawable.active_arrow)); 
     // spec_signup.setIndicator("SIGNUP"); 
     host.addTab(spec_signup); 

    }//oncreate ends 
} 

et le XML: - <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TabHost android:id="@+id/tabhost" android:layout_width="fill_parent" android:layout_height="wrap_content"> <RelativeLayout android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/r2"> <RelativeLayout android:id="@+id/r1" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="270dp"> <LinearLayout android:layout_alignParentBottom="true" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="wrap_content"> <View android:layout_above="@+id/tabs" android:id="@+id/v1" android:layout_width="match_parent" android:layout_height="1dp" android:background="#ccc7c7"/> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout> </RelativeLayout> <FrameLayout android:background="#dede" android:layout_below="@+id/r1" android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="match_parent"> </FrameLayout> </RelativeLayout> </TabHost> </RelativeLayout> `

J'ai ajouté les lignes suivantes et il fonctionne.

LocalActivityManager mLocalActivityManager = new LocalActivityManager(this, false); 
    mLocalActivityManager.dispatchCreate(savedInstanceState); 

    host.setup(mLocalActivityManager);
