android 12

Previous month (February 2021) Google has rolled out the Android 12 first Developer Preview 1 for Pixel devices and after the first update complete Google has released the second version of the Android 12. Google has released this second developer preview with the name of the “Android 12 Developer Preview 1.1” and it comes with lots of improvements while fixes some bugs.

Moving forward, Google has started rolling out the Android 12 Developer Preview 2 for Pixel devices. The new Android 12 Developer Preview 2 comes with lots of new changes and improvements but the company has gives the main attention to notification security and picture-to-picture enhancement.

Looking at these, we will be going very closer to the next major update for the Android 12 version. Google’s developers have to work on it very positively for providing the next-generation version soon and the developers have reached the beta update of this latest version should be the month of May to Android devices. Below you can check the changes of this latest Android 12 Developer Preview 2.

Android 12 Developer Preview 2 Changes:

Trust and safety:

  • Allowing an app to overlay windows on top of other apps poses an obvious security risk. To that end, the new HIDE_OVERLAY_WINDOWS permission introduced in Developer Preview 2 ensures that an app can call Window#setHideOverlayWindows() to indicate that all TYPE_APPLICATION_OVERLAY windows should be hidden when the app’s window is visible.
  • Notification visibility controls have been updated in this new preview release. Now you can configure notification actions so that they will always generate an authentication challenge when triggered from the lock screen. For example, a messaging app now requires authentication before deleting a message or marking it as read.
  • Android 12 Developer Preview 2 has added support for a simpler, more efficient way to obtain the checksum of an installed app. Developers can choose from several standard digest algorithms such as SHA256, SHA512, Merkle Root, and others. A backward compatible version of this feature is in the works, which should be available in the form of a Jetpack library in the near future.

New Android 12 API Changes:

1. Rounded corners:

  • In Android 12 Developer Preview 2, developers can check if the device has a screen with rounded corners and get their details. From the perspective of UI design, one can now utilize the absolute details for each rounded corner as well as the corner details relative to an app’s bounds.

2. Picture in Picture (PIP) improvements:

  • Apps can now enable seamless resize to let the system resize the PIP Activity when needed. In addition, enabling auto-PIP now makes the system directly transition the app to PIP mode on an up-to-home gesture, without waiting for the up-to-home animation to complete. Finally, Android now supports stashing the PIP window by dragging it to the left or right edge of the screen.

3. Updates to companion device app API:

  •  Wearable devices like smartwatches and fitness trackers usually need a dedicated app for managing them. Google wants to make it easier for such apps to be running and connected whenever an associated companion device is nearby. To do that, Android 12 Developer Preview 2 has introduced a new CompanionDeviceService API. Moreover, the new companion device profile greatly simplifies the companion device enrollment process.

4. Bandwidth estimation improvements:

  • Google has greatly enhanced the existing bandwidth estimation APIs. Developers can now get an estimate of aggregate throughput per carrier or Wi-Fi SSID, network type, and signal level, for all users on the device.

5. Visual effects:

  • Applying common graphics effects is now easier than ever in Android 12 with the RenderEffect class. You can now separately apply blurs and color filters, or combine these effects as chain effects as a whole.

Download the Android 12 Developer Preview 2 for Pixel devices:

Check how to install this latest Developer Preview 2 on your Pixel Device:

1. Download Android 12

To get started, you’ll first need to download the files needed to actually put Android 12 on your Pixel. There are two ways to do so. First, you can install a Factory Image, which wipes your phone and starts everything from scratch. Alternatively, and the way we’ll detail here, there’s an OTA file, which installs over your current version of Android without wiping your phone.

You can download the beta OTA file from Google’s Full OTA Image hosting site. That site contains OTA downloads for sideloading different updates, including Android 12, on every Pixel and Nexus device, so you’ll need to scroll down to ensure you are downloading the file that associates with your device. OTA downloads are available here.

For the Android 12 Developer Preview, only Google Pixel 3/XL, Pixel 3a/XL, Pixel 4/XL, Pixel 4a, Pixel 4a 5G, and Pixel 5 are available. You won’t be able to install it on the original Pixel/XL or Pixel 2/XL.

2. Boot into Recovery mode

Next, you’ll boot your Pixel into Recovery mode. To do this, fully power down your handset. Then, hold down on the Power button and the Volume down button at the exact same time until you get to the Bootloader page. You will know you’re in the right place when you see an Android figure lying down on the screen.

Using your volume buttons, scroll down to Recovery mode. Select this by clicking the power button. Alternatively, if you’re already connected to a computer with ADB, you can use the reboot recovery command.

Now you should see a smaller Android lying down with an exclamation mark over it. From here, press the Power button and the Volume up button for about a second to fully enter Recovery mode. Releasing the Volume up button will send you into Recovery.

3. Navigate to ADB sideload

Using the volume buttons, scroll down to Apply update from ADB and select it with the power button. This will launch a mostly blank screen with text near the bottom directing you on how to sideload an OTA, such as this one for the Android 12 Developer Preview.

4. Connect the handset to a computer with ADB tools installed

This step is important as it’s the only way to transfer the downloaded OTA file to your handset. You’ll need to have ADB and Fastboot tools in a handy place. You can download ADB tools from the Android Developers website. You can also use the Universal ADB Drivers from ClockWorkMod which can make the process a bit easier on Windows devices.

5. Enter the sideload command

As long as everything is in place, you can now sideload the OTA file. On Windows, ensure your Command Prompt is directed to the ADB tools folder and type in ADB sideload. If you’re on macOS or Linux, do the same thing in Terminal (use “cd” and “ls” commands to make sure your Terminal is pointed at the right folder, Google it if you need help) but type in ./adb sideload. You’ll then need to insert the file name of the .zip folder you downloaded from Google and hit enter to start the process.

If everything is working properly, you should see some dialog on your computer and handset that shows the process of the sideload and installation process.

6. Reboot your phone

Once the OTA is done installing, you will be taken back to Recovery Mode. The last step to jump into the new update is to select the Reboot Now option with your power button.

Note: This process won’t wipe your device, but it’s good practice to backup any irreplaceable data in case something goes wrong.
