次のエラーが表示されます。

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?

これで、「WifiDirectActivity は、パスの最初の「finalyeartest」の直後にあるはずだと思います。なぜ2つあるのかわからない？

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);

追加のコードが必要な場合はお知らせください。上記のクラスの下には、関係のない Wifi 接続に関するものがあります。うまくいけば...

AndroidManifest.xml でアクティビティを宣言しましたか? 次のようなもの：

<activity android:name=".WiFiDirectActivity"      
    android:theme="@style/AppTheme.NoActionBar">
</activity>
