android：如何啟動庫項目中定義的活動

Question

我正在開發一個 android 應用程序，它使用 androidVNC Viewer 作為庫項目，但我無法從 androidVNC 啟動活動（活動未找到異常）。

另外，如何捆綁一個庫項目並將其用作一個 apk？

更新

我正在使用以下意圖來調用：

Intent call= new Intent("android.androidVNC.androidVNC.LAUNCH");
startActivity(call);

使用以下代碼后更新 2我想我可以開始活動但是得到這個（java.lang.NoSuchFieldError：android.androidVNC.R $ id.textIP）錯誤......

Intent vnc_call = new Intent(getApplicationContext(), androidVNC.class);
            vnc_call.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(login);

after i checked both R.java,androidVNC original and androidVNC when used as library(under generated java files)...what i got is textip is there in orignal R.java but it is not there in the R.java of (generated java files) in the calling項目。

logcat 的 O/P（前幾行）

任何線索？

Answer 1

即使庫項目有自己的 AndroidManifest.xml，它的內容也不會添加到您的構建中。 如果您打算使用庫包含的任何通常在清單中聲明的內容，則必須將它們復制到您的實際應用程序清單中。 這包括活動、廣播接收器、服務、權限等。

Answer 2

假設 lib 和 app 有不同的命名空間：

當按照 mah 的描述將 lib-manifest-info 與 app-manifest 合並時，您是否在活動中包含了不同的名稱空間？

    <application ... >
        <activity
            android:name=".MyActivity" >...

到

    <application ... >
        <activity
            android:name="my.namespace.MyActivity" >...
