this is the manifest.xml file

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="id.co.kendaricall"

Answer 1

I think all of tour activity classes put in any other package. Go to id.co.kendaricall folder and check weather activity classes present or not. If not then find folder where all classes kept. Suppose all classes kept in package id.co.kendaricall.activity so change in manifest

<activity android:name="activity.KontakDetailActivity" />
<activity android:name="activity.SettingActivity" />
<activity android:name="activity.TemplateActivity" />
<activity android:name="activity.KontakListActivity" />
<activity android:name="activity.PencarianActivity" />
<activity android:name="activity.KontakFavoritActivity" />

Thanks.
