Record view works fine on emulator but not on physical device

[amnakashif]

Hello everyone,

Record view works great on my android studio's emulator but whenever i try to record with my phone it provides "null" toast and doesn't record anything.

my emulator is running on API level 28.

whereas my physical device is Samsung A50.
can anyone help please?

Hi @amnakashif
The error shows that you're recording audio on external storage without implementing required permissions,
Probably you're testing the app against a device with API29+.
You can test the Demo on your device to verify that.
