You can enhance your Android device with a launcher. A launcher reimagines the home screen and other screens with a different look, layout, and features you can customize based on your preferences.
Change default Android launcherWith some Android phones you head to Settings > Home, and then you choose the launcher you want. With others you head to Settings > Apps and then hit the settings cog icon in the top corner where you'll then options to change default apps.
AppTec Custom Launcher With AppTec's Custom Launcher, you can offer your users a completely new user experience. The Tool offers companies the ability to define a uniform design on all Android Devices and to only display apps, that have been explicitly authorized.
Performance Issues with Third-Party LaunchersInstalling any third party software on your Android device can cause performance issues if the software is not properly optimized. Any extra software that runs on the system requires operative memory in the RAM as well as storage memory in the Internal Memory of the device.
Your best bet is to start by looking at the sample launcher provided by Google. You can find that in SDK folder:
[Android-SDK]/samples/android-x/Home/
(where x
is API level).
They have provided source code for an example home screen and it should give you a good start.
The next thing I would recommend is actually browsing the source of the default android launcher at the open source repo. You will need git to pull that down and you can find there here.
