boolean onKeyDown(int keyCode, KeyEvent event)

Question

I'm trying implement this method and i get this mistake:

FATAL EXCEPTION: main
android.content.ActivityNotFoundException: Unable to find explicit activity class {app.gestionservicios/android.view.Menu}; have you declared this activity in your AndroidManifest.xml?

This is my code:

Override
    public boolean onKeyDown(int keyCode, KeyEvent event)
    {
        if ((keyCode == KeyEvent.KEYCODE_BACK))
        {
            Intent passIntent = new Intent();
            passIntent.setClass(Listado.this,Menu.class);
            startActivity(passIntent);

            return true;

        }

        return super.onKeyDown(keyCode, event);
    }

And this mi manifiest.xml:

 <activity
            android:name=".Menu"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

I don't know where is this mistake can appear, because in my manifiest.xml is declared the activity menu, and i have the java file Menu. It doesn't show compilation mistake, only execution mistake

Thanks

Make sure that in this code

Intent passIntent = new Intent();
passIntent.setClass(Listado.this,Menu.class);

Menu is your activity, not android.view.Menu class.

Or you can try next code:

Intent passIntent = new Intent();
passIntent.setClass(Listado.this, your_pacakge_name.Menu.class);

where your_pacakge_name - is the name of the package where your Menu activity is declared.
