&gt; The ActionBar will use the android:logo attribute of your manifest, if
&gt; one is provided. That lets you use separate drawable resources for the
&gt; icon (Launcher) and the logo (ActionBar, among other things).

----------

&gt; setDisplayUseLogoEnabled()
&gt;     Enables the use of an alternative image (a &quot;logo&quot;) in the Action
&gt; Bar, instead of the default application icon. A logo is often a wider,
&gt; more detailed image that represents the application. When this is
&gt; enabled, the system uses the logo image defined for the application
&gt; (or the individual activity) in the manifest file, with the
&gt; android:logo attribute. The logo will be resized as necessary to fit
&gt; the height of the Action Bar. (Best practice is to design the logo at
&gt; the same size as your application icon.)

&gt; setDisplayUseLogoEnabled(true) in your activity.

It appears that:

- &lt;code&gt;android:logo&lt;/code&gt; is available in API Level 10, but not API Level 8
- using &lt;code&gt;android:logo&lt;/code&gt; without &lt;code&gt;android:icon&lt;/code&gt; does not set the application icon in the app drawer


My hunch is that &quot;logo&quot; refers to a company logo instead of an application icon.

What are the pros/cons of initializing variables at option 1 vs option 2?

C++: Where to initialize variables in constructor

Right now, I have a program containing a piece of code that looks like this:

    while (arrayList.iterator().hasNext()) {
         //value is equal to a String value
         if( arrayList.iterator().next().equals(value)) {
              // do something 
         }
    }

Am I doing that right, as far as iterating through the ArrayList goes?

The error I am getting is:

    java.lang.ArrayIndexOutOfBoundsException: -1
    	at java.util.ArrayList.get(Unknown Source)

I would show the rest of the code, but it&#39;s pretty extensive, and if I am not doing the iteration correctly, I would assume the only possibility is that I am not initializing the `ArrayList` properly.

How to get text color of TextView?

I&#39;ve been scouring the interwebs (e.g. Android documentation, answers here, etc.) for the answer to what I thought would be a fairly trivial question. How do you achieve a translucent action bar like the ones in [Google Music](http://coreylatislaw.com/wp-content/uploads/2011/07/google-music.png) and [YouTube](http://coreylatislaw.com/wp-content/uploads/2011/07/youtube.png) (links are image examples)?

I want video content to be full screen and not constrained/pushed down by the action bar while still leveraging the benefits of a built in UI component. I can obviously use a completely custom view, but I&#39;d rather leverage the ActionBar if possible.

**Manifest**

    &lt;activity
        android:name=&quot;videoplayer&quot;
        android:theme=&quot;@android:style/Theme.Holo&quot;
        android:launchMode=&quot;singleTop&quot;
        android:configChanges=&quot;keyboardHidden|orientation&quot;/&gt;

**Activity**

    // Setup action bar
    ActionBar actionBar = getActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
    View customActionBarView = getLayoutInflater().inflate(R.layout.player_custom_action_bar, null);
    actionBar.setCustomView(customActionBarView,
                            new ActionBar.LayoutParams(ActionBar.LayoutParams.MATCH_PARENT,
                                                       R.dimen.action_bar_height));
    actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);

**Menu**

    &lt;menu xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;

            android:icon=&quot;@drawable/button1&quot;
            android:showAsAction=&quot;always&quot;/&gt;

        &lt;item
            android:id=&quot;@+id/button2&quot;
            android:icon=&quot;@drawable/button2&quot;
            android:showAsAction=&quot;always&quot;/&gt;

            android:gravity=&quot;center_vertical&quot;/&gt;
    &lt;/LinearLayout&gt;

Custom Translucent Android ActionBar

In my `main.xml` I have

  

      &lt;FrameLayout
       		android:id=&quot;@+id/frameTitle&quot;
       		android:padding=&quot;5dp&quot;
       		android:layout_height=&quot;wrap_content&quot;
       		android:layout_width=&quot;fill_parent&quot;
       		android:background=&quot;@drawable/title_bg&quot;&gt;
                &lt;fragment
       			  android:name=&quot;com.fragment.TitleFragment&quot;
    			  android:id=&quot;@+id/fragmentTag&quot;
    			  android:layout_width=&quot;fill_parent&quot;
    			  android:layout_height=&quot;wrap_content&quot; /&gt;
        		
      &lt;/FrameLayout&gt;

And I&#39;m setting fragment object like this 

    FragmentManager fragmentManager = activity.getSupportFragmentManager();
  	FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    Fragment newFragment = new FragmentType1();
    fragmentTransaction.replace(R.id.frameTitle, casinodetailFragment, &quot;fragmentTag&quot;);
    		
    // fragmentTransaction.addToBackStack(null);
    fragmentTransaction.commit();

It is setting different types of Fragment objects (`FragmentType2,FragmentType3,...`) at different time. Now at some point of time I need to identify which object is currently there.

In **short** I need to do something like this:

    Fragment currentFragment = //what is the way to get current fragment object in FrameLayout R.id.frameTitle

I tried the following  

    TitleFragment titleFragmentById = (TitleFragment) fragmentManager.findFragmentById(R.id.frameTitle);

and 

		TitleFragment titleFragmentByTag = (TitleFragment) fragmentManager.findFragmentByTag(&quot;fragmentTag&quot;);
But **both the objects (titleFragmentById and titleFragmentByTag  ) are `null`**   
Did I miss something?   
I&#39;m using `Compatibility Package, r3` and developing for `API level 7`.

`findFragmentById()` and `findFragmentByTag()` will work if we have set fragment using `fragmentTransaction.replace` or `fragmentTransaction.add`, but will `return null` if we have set the object at xml (like what I have done in my `main.xml`). I think I&#39;m missing something in my XML files.

Get the current fragment object

I currently have a fragment in an overlay. This is for signing in to the service. In the phone app, each of the steps I want to show in the overlay are their own screens and activities. There are 3 parts of the sign-in process and each had their own activity that was called with startActivityForResult(). 

Now I want to do the same thing using fragments and an overlay. The overlay will show a fragment corresponding to each activity. The problem is that these fragments are hosted in an activity in the Honeycomb API. I can get the first fragment working, but then I need to startActivityForResult(), which isn&#39;t possible. Is there something along the lines of startFragmentForResult() where I can kick off a new fragment and when it&#39;s done have it return a result to the previous fragment?

Is there a method that works like start fragment for result?

I have a problem with the gloss effect in app icon at iOS 5 beta 5, in iOS 4 it&#39;s show the effect not gloss, but iOS5 shows the gloss effect. I put the option `Icon already includes gloss effects = YES`, but simply does not work, and it appears that the application Google+ also has the same problem


Icon already includes gloss effects

I&#39;m in need of an icon pack containing flags that correspond with [ISO-3166 country codes](http://www.iso.org/iso/country_codes/iso-3166-1_decoding_table.htm) such as **US**, **CA**, **SE**, **DE** etc. Optimally the flag icons would have names such as **us.png**, **ca.png** and so on. I&#39;m guessing this is a common developer necessity making this a great place to ask.

Is there a good flag icon pack that corresponds to ISO-3166 Country Codes?

I am about to create my first Android **native** (so not browser based) app and looking for some good practices regarding icon creating/provisioning.
Since it should support multiple devices/resolutions I thought it is best to use SVG to create them. There is at least this lib: http://code.google.com/p/svg-android/ that promises to offer support for SVG on Android.

So far, I have not found resources describing the usage of this or another library as a means to render SVG Icons on the device, so I am a bit reluctant in using it. The best I have seen so far is using SVG as the source format for pre-rendering png based icons in different resolutions.

So my questions is: Are SVG icons a good option to use directly on the device without a png pre-rendering step (does it work at all), and if, why does nobody seem to use this approach?


What are best practices for using SVG icons on Android?

According to [Action Bar Icons][1] action bar icon for the mdpi screen should be 24 x 24 px but the icons in [Action Bar Icon Pack][2] for mdpi are 32 x 32 px. The sizes do not match for other screen sizes neither. So which one is correct and what dimensions should the action bar icon have?

I have installed an application, when I try to run it (it&#39;s an executable jar) nothing happens. When I run it from the commandline with: 
&gt;java -jar &quot;app.jar&quot;

I get the following message:
&gt;no main manifest attribute, in &quot;app.jar&quot;

Normally, if I had created the program myself, I would have added a main class attribute to the manifest file. But in this case, since the file is from an application, i cannot do that. I also tried extracting the jar to see if I could find the main class, but there are to many classes and none of them has the word &quot;main&quot; in it&#39;s name. There must be a way to fix this because the program runs fine on other systems.

Is there a way to define some kind of handling mechanism in Android **and** iOS that would allow me to do intercept either of the following:

    myapp:///events/3/
    - or -
    http://myapp.com/events/3/

I&#39;d like to &#39;listen&#39; for either the protocol or the host, and open a corresponding Activity / ViewController.

I&#39;d like too if these could be as system wide as possible. I imagine this will be more of an issue on iOS, but I&#39;d ideally be able to click either of those two schemes, as hyperlinks, from any app. Gmail, Safari, etc.
