From [Material Design Keylines Touch Target Size][1], size for icons is `24dp`


  [1]: http://www.google.com/design/spec/layout/metrics-keylines.html#metrics-keylines-touch-target-size

Full icon size should be `24dp` with a &quot;live&quot; area of `20dp`.

I would like to know how can I add Boon or Jackson parser to an android project using Gradle?

I found how to do so with GSON but couldn&#39;t find anything with Boon or Jackson.

How can I add Boon or Jackson JSON parsers to Android project with Gradle?

My app shows a map and i want that users can&#39;t swipe over a certain region.
So i&#39;m trying to add bounds but it makes the app to crash.
Here is the working code:

	public class MapViewer extends Activity implements OnInfoWindowClickListener {
		private LatLng defaultLatLng = new LatLng(42.564241, 12.22759);
		private GoogleMap map;
		private int zoomLevel = 5;
		private Database db = new Database(this);
		  
		protected void onCreate(Bundle savedInstanceState) {
			super.onCreate(savedInstanceState);
			setContentView(R.layout.mapviewer);
		 
			try {
				map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
				if (map != null) {
					map.setMyLocationEnabled(true);
					map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
					map.getUiSettings().setRotateGesturesEnabled(false);
		 
					map.moveCamera(CameraUpdateFactory.newLatLngZoom(defaultLatLng, zoomLevel));
					 
					this.addMerchantMarkers(new MarkerOptions());
					
					map.setOnInfoWindowClickListener(this);
				}
			} catch (NullPointerException e) {
				e.printStackTrace();
			}
		}
		 
		@Override
		public void onPause() {
			if (map != null) {
				map.setMyLocationEnabled(false);
				map.setTrafficEnabled(false);
			}
			super.onPause();
		}
	
		public void addMerchantMarkers(MarkerOptions mo) {
			SQLiteDatabase dbRead = db.getReadableDatabase();
			String[] columns = {&quot;title&quot;, &quot;addr&quot;, &quot;lat&quot;, &quot;lon&quot;};
			Cursor result = dbRead.query(&quot;merchants&quot;, columns, null, null, null, null, null);
		
			while(result.moveToNext()) {
				String merchant = result.getString(0);
				String address = result.getString(1);
				float lat = result.getFloat(2);
				float lon = result.getFloat(3);
			
				LatLng pos = new LatLng(lat, lon);
			
				map.addMarker(mo.position(pos)
						.title(merchant)
						.snippet(address)
						.icon(BitmapDescriptorFactory.fromResource(R.drawable.marker_50)));;
			}
		}
	}

And this is the code i add in onCreate method that cause the crash:

		LatLngBounds.Builder builder = new LatLngBounds.Builder();
		builder.include(new LatLng(47.09194444, 18.52166666));
		builder.include(new LatLng(36.448311, 6.62555555));
		LatLngBounds bounds = builder.build();
		
		CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, 30);

		map.animateCamera(cu);


Here is the LogCat:

I have an Android-based phone (2.3.6) with unlocked root privileges.
Since i&#39;d like to have access to my phone through my computer, today i&#39;ve installed QtAdb and Android SDK.
If i open a command prompt and i do

&gt; adb shell su

i get

&gt; #

And so I am able to copy, remove, push files on my phone (on the phone i get a notification using the app &quot;SuperSU&quot;.)

But if i launch QtAdb - under Windows 7 - i get the following error: &quot;adbd cannot run as root in production builds&quot;. I miss something? There&#39;s something wrong with QtAdb?

Any idea on what might cause this issue?

It definitely recognizes the device.  Could it be an issue with the apk?

Standard `ListView` selector in android L developer preview uses `colorControlHighlight` for the ripple effect on touch and has a transparent background in unfocused state.

I would like to define a `ListView` item that has a colored background and still shows the ripple effect on touch with the same highlight color. Now, if I define the following drawable:

    &lt;ripple xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
            android:color=&quot;?android:colorControlHighlight&quot;&gt;
        &lt;item android:drawable=&quot;@color/my_background_color&quot;/&gt;
    &lt;/ripple&gt;

it works, but the ripple starts in the middle of the `ListView` item, regardless of the touch position. If I use the same background outside of the `ListView`, e.g. for a `LinearLayout`, it works like expected (the ripple starts on the touch position).

First of all, [this question][1] asks a very similar question. However, my question has a subtle difference.

What I&#39;d like to know is whether it is possible to programmatically change the `colorPrimary` attribute of a theme to an ***arbitrary*** color?

So for example, we have:

    &lt;style name=&quot;AppTheme&quot; parent=&quot;android:Theme.Material.Light&quot;&gt;
        &lt;item name=&quot;android:colorPrimary&quot;&gt;#ff0000&lt;/item&gt;
        &lt;item name=&quot;android:colorAccent&quot;&gt;#ff0000&lt;/item&gt;
    &lt;/style&gt;

At runtime, the user decides he wants to use `#ccffff` as a primary color. Ofcourse there&#39;s no way I can create themes for all possible colors.

I don&#39;t mind if I have to do hacky stuff, like relying on Android&#39;s private internals, as long as it works using the public SDK.

My goal is to eventually have the `ActionBar` *and* all widgets like a `CheckBox` to use this primary color.

**Update (11/10/14): Genymotion has released 2.3.1 which fixes this issue. https://cloud.genymotion.com/page/changelog/#231**

Update (10/21/14): Genymotion replied to my support email and indicated the solution recommended by @plackemacher below is the suggested fix at the moment. They are aware of the issue.

Since upgrading to Lollipop, I&#39;m having adb issues when using a Genymotion emulator. Devices don&#39;t show up in Android Studio, and I&#39;ve also gotten the following error when trying to run `adb devices`:

    $ adb devices

    adb server is out of date.  killing...
    cannot bind &#39;tcp:5037&#39;
    ADB server didn&#39;t ACK
    * failed to start daemon *
    error:

I&#39;m not sure if it&#39;s because of the Lollipop upgrade or coincidence. 


**Edit/update**: 

Per Chris Satton&#39;s comment, I investigated if multiple adb processes were running (`ps aux | grep adb`), and it looks like it&#39;s a Genymotion conflict(?). It looks to include its own version of adb.

How to use &lt;md-icon&gt; in Angular Material?

I&#39;m confused on button styles for material design. I&#39;d like to get colorful raised buttons like in the attached link., like the &quot;force stop&quot; and &quot;uninstall&quot; buttons seen under the usage section. Are there available styles or do I need to define them?

http://www.google.com/design/spec/components/buttons.html#buttons-usage

I couldn&#39;t find the default button styles. 

Example:

     &lt;Button style=&quot;@style/PrimaryButton&quot;
        android:layout_width=&quot;wrap_content&quot;
        android:layout_height=&quot;wrap_content&quot;
        android:text=&quot;Calculate&quot;
        android:id=&quot;@+id/button3&quot;
        android:layout_below=&quot;@+id/editText5&quot;
        android:layout_alignEnd=&quot;@+id/editText5&quot;
        android:enabled=&quot;true&quot; /&gt;

If I try to change the background color of the button by adding 

        android:background=&quot;@color/primary&quot;

all of the styles go away, such as the touch animation, shadow, rounded corner, etc. 


Android Material Design Button Styles

I&#39;ve added the appCompat material design to my app and it seems that the alert dialogs are not using my primary, primaryDark, or accent colors. 

Here is my base style:

    &lt;style name=&quot;MaterialNavyTheme&quot; parent=&quot;@style/Theme.AppCompat.Light.DarkActionBar&quot;&gt;
        &lt;item name=&quot;colorPrimary&quot;&gt;@color/apptheme_color&lt;/item&gt;
        &lt;item name=&quot;colorPrimaryDark&quot;&gt;@color/apptheme_color_dark&lt;/item&gt;
        &lt;item name=&quot;colorAccent&quot;&gt;@color/apptheme_color&lt;/item&gt;
        &lt;item name=&quot;android:textColorPrimary&quot;&gt;@color/action_bar_gray&lt;/item&gt;
    &lt;/style&gt;

Based on my understanding the dialogs button text should also use these colors. Am I wrong on my understanding or is there something more I need to do?

---

**Solution:** 

The marked answer got me on the right track.

    &lt;style name=&quot;MaterialNavyTheme&quot; parent=&quot;@style/Theme.AppCompat.Light.DarkActionBar&quot;&gt;
        &lt;item name=&quot;colorPrimary&quot;&gt;@color/apptheme_color&lt;/item&gt;
        &lt;item name=&quot;colorPrimaryDark&quot;&gt;@color/apptheme_color_dark&lt;/item&gt;
        &lt;item name=&quot;colorAccent&quot;&gt;@color/apptheme_color&lt;/item&gt;
        &lt;item name=&quot;android:actionModeBackground&quot;&gt;@color/apptheme_color_dark&lt;/item&gt;
        &lt;item name=&quot;android:textColorPrimary&quot;&gt;@color/action_bar_gray&lt;/item&gt;
        &lt;item name=&quot;sdlDialogStyle&quot;&gt;@style/DialogStyleLight&lt;/item&gt;
        &lt;item name=&quot;android:seekBarStyle&quot;&gt;@style/SeekBarNavyTheme&lt;/item&gt;
    &lt;/style&gt;

    &lt;style name=&quot;StyledDialog&quot; parent=&quot;Theme.AppCompat.Light.Dialog&quot;&gt;
        &lt;item name=&quot;colorPrimary&quot;&gt;@color/apptheme_color&lt;/item&gt;
        &lt;item name=&quot;colorPrimaryDark&quot;&gt;@color/apptheme_color_dark&lt;/item&gt;
        &lt;item name=&quot;colorAccent&quot;&gt;@color/apptheme_color&lt;/item&gt;
    &lt;/style&gt;

Material Design not styling alert dialogs

I&#39;m developing an simple app to test the material design. I&#39;m using `com.android.support:appcompat-v7:21.0.0` and my activity looks like:

    public class MyActivity extends ActionBarActivity {
       ...
    }

The layout is defined as:

    &lt;LinearLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        xmlns:tools=&quot;http://schemas.android.com/tools&quot;
        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;match_parent&quot;
        tools:context=&quot;.MyActivity&quot;&gt;
    
        &lt;android.support.v7.widget.Toolbar
            xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
            android:id=&quot;@+id/toolbar&quot;
            android:layout_width=&quot;match_parent&quot;
            android:layout_height=&quot;128dp&quot;
            android:minHeight=&quot;?attr/actionBarSize&quot;
            android:background=&quot;?attr/colorPrimaryDark&quot;/&gt;
    &lt;/LinearLayout&gt;

Now i defined my theme following material guidelines:

    &lt;style name=&quot;AppTheme&quot; parent=&quot;Theme.AppCompat.NoActionBar&quot;&gt;
        &lt;item name=&quot;colorPrimary&quot;&gt;@color/colorPrimary500&lt;/item&gt;
        &lt;item name=&quot;colorPrimaryDark&quot;&gt;@color/colorPrimaryDark700&lt;/item&gt;
    &lt;/style&gt;

I&#39;d like to change the status bar color in pre Android 5 and set it to `colorPrimaryDark` but i can&#39;t find the way. I tried using:

    getWindow().setStatusBarColor(..)

but setStatusBar color is available from level 21. 
Why if i define a `colorPrimaryDark` in my theme and use appcompact the status bar doesn&#39;t change color?
Anyone can help?
