Запуск активности в Tab Failed

Question

В моем приложении я хочу запустить активность в моей вкладке. Таким образом, разные вкладки должны содержать разные виды деятельности из разных проектов. Каждое действие представляет собой проект импортированного модуля, который создается и тестируется отдельно. Проблема возникает, когда я создаю приложение, оно падает.

MainActivity

package sst1.emily.example.com.sst1; 

import android.content.Intent; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.TabHost; 

public class MainActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     TabHost host = (TabHost)findViewById(R.id.tabHost); 
     host.setup(); 

//Tab 1 
     TabHost.TabSpec spec = host.newTabSpec("Tab One"); 
     spec.setIndicator("Tab One"); 
     host.addTab(spec); 
     Intent intent = new Intent(); 
     intent.setClassName("attendance.emily.example.com.attendance", "MainActivity"); 
     spec.setContent(intent); 

     //Tab 2 
     spec = host.newTabSpec("Tab Two"); 
     spec.setContent(R.id.tab2); 
     spec.setIndicator("Tab Two"); 
     host.addTab(spec); 

     //Tab 3 
     spec = host.newTabSpec("Tab Three"); 
     spec.setContent(R.id.tab3); 
     spec.setIndicator("Tab Three"); 
     host.addTab(spec); 
    } }

Любая идея, какую часть я сделал не так?

Answer 1

Деятельность-в-tabs устарела для шесть лет. Они никогда не поддерживали действия, поступающие из других приложений.
