In the previous article we got a basic app set up and got our images set up ready to create an image in which part of the colour could change depending on the values of three SeekBars representing the red, green, and blue components. In this article we’ll look at how we actually apply those colour values and create the required image.
Following on from last week’s minor detour, we’ll resume this series by adding another new feature that was introduced in Android 4.2 (Jelly Bean): Daydreams.
A PC-style screensaver is not practical on a mobile device much of the time because on a mobile device you want to power down the display when the device is idle to conserve power. However, from 4.2 onwards Android supports a Daydream which is a screensaver mode which becomes active when the device is connected to an external power source, and typically the Daydream is displayed rather than powering down the display as power is not so much of an issue. This can be useful for having a night mode, or providing custom behaviours when the device is docked. In this article we’ll add a Daydream to our Text Clock app.
In the previous articles in this series we’ve been looking at creating an extremely simple app which has been published to Google Play. Since the update covered in the last article (V1.1.0) was published a bug has been discovered in the app. In this article we’ll look at the tools available to developers to enable us to detect bugs, and implement a fix.
