Google has just launched Android 11 Beta 2, which brings with it a new platform stability milestone. For the first time, this new milestone has been implemented to let developers know that the way their apps work in this beta will be how their apps will behave when Android 11's stable version is released. This second beta is now available for the Google Pixel 2, Pixel 3, Pixel 3a, or Pixel 4.
For this seventh official release of the platform, it was done in response to developers' requests. Before this, Google could make changes to APIs and other app-facing parts of Android up to the stable launch. But now, with Beta 2, everything that would affect developers' apps will be final, giving them the confidence to anticipate how their apps will work when the new OS is released. It gives developers time to work out details of their apps and tweak things without worrying that Android 11 will change again before the stable launch.
If you have the first beta version and the 1.5 one, don't expect much to change here. It's more of a refinement, with the focus on the nitty-gritty details. But one late and newly added feature allows developers to access multiple cameras at once, which could mean a camera app can take two photos simultaneously (like having the front and rear cameras work at the same time).
The release of Beta 2 also suggests that it's now very close to being ready for a stable launch. Rumour has it Android 11 could be launched on September 8, which could mean this will be the second-to-the-last version of the OS before the official release. Beta 3 could come out in August.
