android过滤第三应用列表

转载自：http://blog.youkuaiyun.com/santicom/article/details/7465751

调用所有匹配的第三应用：

[java]  view plain copy

1. public class AppFilterActivity extends Activity  
2. {  
3.     @Override  
4.     public void onCreate(Bundle savedInstanceState)  
5.     {  
6.         super.onCreate(savedInstanceState);  
7.         setContentView(R.layout.main);  
8.   
9.         Intent intent = new Intent(Intent.ACTION_ATTACH_DATA);  
10.         intent.setType("image/png");  
11.   
12.         Intent chooserIntent = Intent.createChooser(intent, "Select app");  
13.         if (chooserIntent == null)  
14.         {  
15.             return;  
16.         }  
17.         startActivity(chooserIntent);  
18.     }  
19. }
