Android - Activity not found exception error

Question

I get the following error:

android.content.ActivityNotFoundException: Unable to find explicit activity class {ie.ittralee.finalyeartest.finalyeartest/ie.ittralee.finalyeartest.finalyeartest.WiFiDirectActivity}; have you declared this activity in your AndroidManifest.xml?

Now I believe that 'WifiDirectActivity should be right after the first 'finalyeartest' in the path. Not sure why there is two?

WifiDirectActivity.java

import ie.ittralee.finalyeartest.finalyeartest.DeviceListFragment.DeviceActionListener;

import static ie.ittralee.finalyeartest.finalyeartest.R.id.frag_list;


public class WiFiDirectActivity extends Activity implements ChannelListener, DeviceActionListener {

    public static final String TAG = "LightShare";
    private WifiP2pManager manager;
    private boolean isWifiP2pEnabled = false;
    private boolean retryChannel = false;

    private final IntentFilter intentFilter = new IntentFilter();
    private Channel channel;
    private BroadcastReceiver receiver = null;

    /**
     * @param isWifiP2pEnabled the isWifiP2pEnabled to set
     */
    public void setIsWifiP2pEnabled(boolean isWifiP2pEnabled) {
        this.isWifiP2pEnabled = isWifiP2pEnabled;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

...More code    

If you need any extra code let me know. Below the above class is just some Wifi connection stuff, not related. Hopefully not...

Answer 1

Add your activity to the manifest like this:

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="Light Share"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".ShareFilesActivity"></activity>
    <activity android:name=".WiFiDirectActivity">

    <!-- Used for transferring files  after a successful connection -->
    <service android:enabled="true" android:name=".FileTransferService" />
</application>
