Jun 29, 2016 The Android user interface design guidelines have changes over the years. The first big change for designing Android applications came with the Android 3.0 (Honeycomb) release which introduced the Holo style. The Android 5.0 (Lollipop) release was again a radical change with the Material design. The material design introduces depth into the layout and uses much more animations to.

3.1 Introduction
The Tip Calculator app (Fig. 3.1(a)) calculates and displays the tip and total for a restaurant bill amount. As you touch the numeric keypad to enter the bill amount’s digits, the app calculates and displays the tip and total bill amounts for the current tip percentage (15% by default). You specify a tip percentage from 0% to 30% by moving the SeekBarthumb—this updates the displayed tip percentage and recalculates the tip and total. All numeric values are displayed using locale-specific formatting. Figure 3.1(b) shows the app after the user enters the amount 56.32 and changes the tip percentage to 25%.

You’ll begin by test-driving the app. Then we’ll overview the technologies you’ll use to create the app. You’ll build the app’s GUI using Android Studio’s layout editor and the Component Tree window. Finally, we’ll present the complete Java code for the app and do a detailed code walkthrough.
Note Regarding the Keyboard in Our Screen Captures
The keypad in Fig. 3.1 may differ, based on your AVD’s or device’s Android version or whether you’ve installed and selected a custom keyboard on your device. We configured our AVD to display the dark keyboard Mirror photo app for android free download 0 12 1. for better contrast in our screen captures. To do so:
- Touch the home () icon on your AVD or device.
- On the home screen, touch the launcher () icon, then open the Settings app.
- In the Personal section, touch Language and Input.
- On an AVD, touch Android Keyboard (AOSP). On a device touch Google Keyboard—we assume you’re using the standard Android keyboard.
- Touch Appearance & layouts, then touch Theme.
- Touch Material Dark to change to the keyboard with the dark background.

Description of ChangeOn Android Color.Accent is set to a hardcoded value in Xamarin.Forms.Forms.SetupInit (in the Platform.Android project) and it cannot be changed by the user. This color is then used as text and separator color for TableSections. The user cannot override the color. As the hardcoded color may not fit to the users app theme, this should be changed. Jason Smith said on forms-devel that the code should read from the current Android theme. This change does that. I wouldn't know how to unit test this. Bugs FixedAPI ChangesNone Behavioral ChangesColor.Accent will be set to the accentColor of the current Android theme instead of the hardcoded values. PR Checklist
