I cannot see what i'm drawing on android

[yepes]

Hi
I have created a small demo because I cannot have this library to work on android <31. The same code works on api 31, 32, 33 and 34.

The thing is that I cannot see what is being draw, but the data is there. This is on an emulator API 31:

This is the same on API 28:

As you can see, the data signature is there, you just can see it.

This is what I have in my package.json:
"react": "18.2.0",
"react-native": "0.72.4",
"react-native-signature-canvas": "^4.6.1",
"react-native-webview": "^13.6.0"

It's a bare RN project.

I created a repro repo here:

I managed to test it on an real device on android api 29 and works on the real device, but de behaviour on the emulator is the described above

Sorry to keep you waiting. After this period of troubleshooting, I have determined the cause of the problem and released a new version to fix it.

npm i react-native-signature-canvas@4.7.1

and then,

set props androidLayerType to 'software' for fix it

<SignatureScreen
androidLayerType={'software'}/>

@YanYuanFE I can confirm it works. The signature on android is not as crisp as in iOS, but yeah, it works.

Thanks
