upnp 學習筆記二

現在從用戶端入手

剛搭的環境eclipse4.2+adt20

建立工程UpnpBrowser-110712

下載下傳用戶端源碼

http://4thline.org/projects/download/misc/UpnpBrowser-110712.tar.gz

包解壓後将應用源碼直接複制過來

可能缺少兩個jar包

cling-core-1.0.5.jar

teleal-common-1.0.13.jar

不要放在libs目錄下，這樣好象不能source attachment

下載下傳源碼檔案導入工程這樣就可以檢視cling的源碼了

示例代碼如下：

public class MainActivity extends TabActivity {

private static Logger log = Logger.getLogger

(MainActivity.class.getName());

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

// Fix the logging integration between java.util.logging and

Android internal logging

LoggingUtil.resetRootHandler(new FixedAndroidHandler());

Logger.getLogger("org.teleal.cling").setLevel(Level.INFO);

setContentView(R.layout.main);

TabHost tabHost = getTabHost();

TabHost.TabSpec spec;

Intent intent;

// 顯示裝置清單頁

intent = new Intent().setClass(this, BrowseActivity.class);

spec = tabHost.newTabSpec("browse").setIndicator("Browse LAN",

getResources().getDrawable(R.drawable.ic_tab_browse)).setContent(intent);

tabHost.addTab(spec);

// 開關示範執行個體

intent = new Intent().setClass(this, DemoActivity.class);

spec = tabHost.newTabSpec("demo").setIndicator("Demo Light",

getResources().getDrawable(R.drawable.ic_tab_demo)).setContent(intent);

tabHost.addTab(spec);

tabHost.setCurrentTab(0);

}
