I want to capture multiple images at once use front camera. After research I know I can use intent to achieve my expect with action MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA as I found this :
How to take multiple photos before dismissing camera intent?
But the answer accepted do not tell how to use ContentObserver.
Can you help give me a code example for this?
I also found a good library can capture multiple images but this lib do not support front camera ( I need front camera to capture selfie )
https://github.com/jaydeepw/poly-picker
Is there any lib like poly picker which support front camera ?
