Difference between Launcher and Theme in Android - android-theme

I'm currently working on launcher based Android app,can any one tell me the difference between launcher vs theme(Which we usually downloaded from App Stores)?

theme is the general look of a phone's UI like the shape, size and color of icons the look of the menu, the background photo or color but the Launcher is an application itself a third-party user interface (UI) programs which take over the duties performed by the factory UI.

Change Font style for keyboard in tizen wearable(Web application)

I'm using Roboto throughout my screens for tizen wearable. But wearable's system font is getting applied to the Keyboard's letters and alphabets. Do we have any control over the keyboard layout's font style from HTML?
You can developed your own styled keyboard using Tizen Web IME (Input Method Editor).
IME applications differ from other applications in that they do not follow the normal application life-cycle management and they need a mechanism to interact with the client application requesting the IME.
Tizen provides a special architecture to guarantee that Web IME applications work just like native IME applications (however, there are some restrictions due to the capability limitations of the Web applications in general). A Web IME application can be run within the core Input Service Engine process, which is also used to run native IME applications.
You can find Template of IME app in Tizen IDE.
To create an IME application:
To create the Web IME project, launch the Tizen IDE and go to File >
New > Tizen Wearable Web Project > Template > IME Application > Web
IME application.
Enter the project name and click Finish.
After installing tha app you have to change the Text Input from the Settings

can't run the emulator in android studio 2.0

I wan't to use the camera in my application but when I ran the emulator it shows this:
And this is my setting:
Try this:
Right-click on the Desktop and click Nvidia Control Panel. Click
Manage 3D settings. Click Program Settings. Select SketchUp from the
drop-down list. There are five settings that you need to configure:
Anisotropic Filtering set to Application Controlled.
Antialiasing FxAA set to On.
Antialiasing Gamma set to On.
Antialiasing Mode set to Application Controlled.
Open GL set to the name of the video card that you have.
This might remedy the situation where you have incorrect OpenGL settings. However if you have an old card with a small amount of VRAM you might unfortunately be unable to run the emulator of that system.

UWP Tile Text Color

I am trying to set the text color on my UWP app's primary Start Menu tile so that it is black. (I am doing this because my app's icon calls for a white background, and you cannot see white text on a white background.) I found the answer to this question, but it discusses Windows 8 apps, and the UI described in the answer does not seem to exist anymore when developing for Windows 10. Does anyone know how to do this on a Windows 10 UWP app?
The way of doing this in a UWP app has changed slightly. Set the ForegroundText attribute to "dark" in the VisualElements node.

How to create a taskbar application similar to Touch Keyboard on Windows 8.1?

On Windows 8.1, if you right-click on the taskbar and point to Toolbars you can turn on Touch Keyboard, which makes a small image of a keyboard appear at the far right of the task bar just to the left of the notification area.
I want to develop an application that can make a presence here with a dynamically updating display of a time string (a count down application).
Can anyone advise if this is possible using C# .NET?
From various research I've discovered it is extremely difficult to determine exactly what Microsoft refer to this utility as. I have seen 'deskbar', 'deskband' and obviously it's under 'toolbars' in the task bar context menu. It also seems every major OS release changes the terminology and functionality completely. So bonus points if anyone can clear up what it's called on Windows 8.1 in addition to what term to research or MSDN article to read about developing an application that sits there.

After migrate Xamarin iOS project to Unified API, the app shows black screen only.
Apparently all resources are not loaded at all.

Any advice to solve this?
In some cases XI 8.6.0 new msbuild-based build system can forget to copy some files into the app bundle.
This is fixed in the service release (8.6.1) which is in the alpha channel (right now). You might want to try it to see if this is the issue (if not then please file a bug report so it can be investigated).
