    <application>
        <activity android:name=".com.tabwidget.Tab"></activity>
        <activity android:name=".com.tabwidget.TabHostProvider"></activity>
        <activity android:name=".com.tabwidget.TabView"></activity>
    </application>
</manifest>                  
<manifest package="com.kpbird.tabbarcontrol">

    </application>

But I am getting exception Unable to find explicit activity class ...........Where was i wrong? Please help me...........

Answer 1

It seems you have made a few mistakes in the XML:

<manifest package="com.tabwidget">
    <application>

        1) BELOW: starting the names by "." means that
        you are implicitely extending the package prefix defined in the package 
        attribute of the manifest XML tag. 
        For example, if your package is "com.tabwidget", defining".MyActivity"
        will be interpreted as "com.tabwidget.MyActivity"
        By removing the first ".", you use an explicit notation instead:
        whatever your package is, "com.tabwidget.MyActivity" is interpreted
        as "com.tabwidget.MyActivity"
        <activity android:name=".com.tabwidget.Tab"></activity>
        <activity android:name=".com.tabwidget.TabHostProvider"></activity>
        <activity android:name=".com.tabwidget.TabView"></activity>
    </application>
</manifest>                  

2) BELOW: a manifest file should only contain one manifest XML tag:
<manifest package="com.kpbird.tabbarcontrol">
    <application>

        3) BELOW: same mistake as 1)
        <activity android:name=".com.kpbird.tabbarcontrol.TabbarView"></activity>
    </application>
</manifest>

What follows should work. It fixes these 3 mistakes:

<manifest package="com.kpbird.tabbarcontrol">
    <application>
        <activity android:name="com.tabwidget.Tab"></activity>
        <activity android:name="com.tabwidget.TabHostProvider"></activity>
        <activity android:name="com.tabwidget.TabView"></activity>
        <activity android:name=".TabbarView"></activity>
    </application>
</manifest>

Answer 2

you can do like this . you need no to do any explicit inclusion of different package

<manifest package="com.tabwidget">
<application>
    <activity android:name="com.tabwidget.Tab"></activity>
    <activity android:name="com.tabwidget.TabHostProvider"></activity>
    <activity android:name="com.tabwidget.TabView"></activity>
    <activity android:name="com.tabwidget.TabbarView"></activity>
</application>
