I am developing an android application and one part of it is to check whether the wifi of the phone is enabled or not.

Answer 1

I guess you need the ACCESS_NETWORK_STATE in your manifest.

Answer 2

Need to check your main class(MainActivity) file is mentioned or not in 'Manifest.xml'.

<activity
            android:label="@string/app_name"
            android:name="com.androidexample.demo.MainActivity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
</activity>
