Opening new activity from menu

I'm writing app for android and I have some problems. I have main activity and settings activity. I want to start settings activity from main activity menu. I have this code to do this:

@Override
public boolean onCreateOptionsMenu(Menu menu)
{
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
    switch (item.getItemId())
    {
    case R.id.menu_preferences:
        Intent j = new Intent(getApplicationContext(), SettingsActivity.class);
        startActivity(j);
        break;
    default:
        break;
    }
    return super.onOptionsItemSelected(item);
}

But it isn't working. When i'm trying it i have logcat:

Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@40a254c8

And settings activity isn't showing. I don't know what to do...

Firstly you shouldn't use getApplicationContext as context. It should be like this: 

    Intent j = new Intent(Firstclass.this, Secondclass.class);
    startActivity(j);

Don't forget to declare the Activity in your manifest and return true at the end. Hope this helps

Declare SettingsActivity in manifest. also use MainActivity.this instead of getApplicationContext(). this should help.

Replace this line

return super.onOptionsItemSelected(item);

with this one

return true;

Add SettingsActivity in your manifest file.

<activity android:name="yourmainpackagename.SettingsActivity " />

Hope this helps.
