Issue #22

Checking app accessibility, handling focus, converting Flow to LiveData, and breaking RSA ⛏

Well hello, what have we here?

It’s just another issue of the Android Dev Newsletter 😎
Let’s see what we have here for today 👇

If these links don't work in your email client, try reading this issue on my website.

1) Is your app accessible? Check it out with Accessibility Scanner!

2) How to handle focus in Jetpack Compose with examples

3) Be careful when converting Flow to LiveData

4) Breaking RSA with a Quantum Computer

1) This text explains how developers can use Accessibility Scanner, a tool developed by Google, to improve the accessibility of their Android apps. With this tool, developers can uncover opportunities to improve accessibility that may be overlooked with manual testing.

2) This article explains how to use the FocusRequester, FocusManager, and various focus-related Modifiers to control text focus in Jetpack Compose.

3) This text discusses how to use the androidx.lifecycle function asLiveData() to convert a Flow to a LiveData and why you should be careful when doing that if you want to have the right state emitted.

4) This article discusses a recent paper from Chinese researchers claiming to be able to break 2048-bit RSA encryption. This is significant as it requires a much smaller quantum computer than expected, only 372 qbits compared to millions. The researchers were able to factor 48-bit numbers using a 10-qbit quantum computer, showing their potential. While this is a potentially groundbreaking development, the researchers have yet to actually break 2048-bit RSA.
