@Peter Simpson
Thank you for your nice answer.
But i tried all these methods with in each case a limitation or freeze :
- "Intent"method cannot use front camera, and no protrait,
- Cameraex : I never sucessed to reach the picture taken on my phone.
When i try to modify the path where the picture is put, the app exits with the only one message "Unfortunately the App closed" When i try to follow in debug mode, the app close without any message.
- Camera2 2017 : I successed to reach the picture taken on my phone, but i don't success to modify its path, and when i take a picture with the front camera, the picture is inverted left to right. In addition the implementation of this camera function in my app is quite heavy and complex.
Thank you for your advices.
