Google released the Android 12 Developer Preview 3 on Wednesday (21). This preliminary facing developer brings some minor changes that users will notice, like a splash screen when starting apps, improved notifications for calls, haptic feedback improved in games, and additional features for camera apps.
Android 12 is one of the interfaces that feature iOS – the opening screen (splash screen or launch screen). When you open an app, the system will not display the interface right away: instead, you will see the icon in a larger size or an animation. This is enabled by default for all applications.
Google says that with this, launching apps will become a more consistent and enjoyable experience. Meanwhile, Apple says that the launch screen on iOS only serves to improve the perception that your app loads quickly and that it is immediately ready to use.
In Android 12, you can use new APIs to choose the background colour on the splash screen. And replace the app icon (which is the default) with a custom icon or an animation. A leak from XDA Developers had already shown how this works.
Camera improvements on Android 12 Preview
Also, Android 12 is adapting to phones with more advanced cameras. Many manufacturers have custom camera effects like HDR, night mode, and bokeh (blur background), but those were not so accessible for developers creating their apps. These additional features are now easier to use through the Camera2 package, without requiring significant code changes.
And you know those phones with 48, 64, or 108 megapixels? They combine the adjacent pixels to act as one to capture more light. And this technique can be used by third-party apps, thanks to new APIs.
Google will change the call notification interface. This includes traditional calls from your operator, video meetings, and more. The company did not release images, but explains that apps can indicate the importance of active calls by displaying a prominent notice with the length of time in the status bar; when you touch it, you return to the call.
There’s something special about gaming on Android 12 DP3: more tools for creating haptic feedback. The cell phone trembles in your hand thanks to different actuators built into the inside; developers can access these actuators independently to create more immersive and complex effects.
And a change in the way Android 12 makes backups caught my attention. When configuring a new smartphone, the user can choose whether their data will come from the cloud (Google Drive ) or another device nearby. The developer now has greater freedom within these two scenarios: for example, it is possible to prevent a large file from being saved in the cloud but to release its transfer to a new cell phone.
