Do you have an activity called video_4? In your manifest youve set
video_4 as the launch activity..confirm if this is the issue, if so,
you need to set Videos as the launch activity when the app
launches.i.e
Replace:
<activity android:name=".video_4"
android:label="@string/app_name"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
With:
<Activity android:name=".Videos"
android:label="@string/video_play"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
This means you will remove the other:
<Activity android:name=".Videos"
android:label="@string/video_play"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
s that Videos is in the manifest only once.
