Could have used:

static final String TAG = "Robust image source identification on modern smartphones camera";

cff225e41e/app/src/main/java/com/termux/api/apis/CameraPhotoAPI.java (L79)

e62bdadea3/scripts/termux-camera-photo.in

Is not there an open-source app able to capture RAW images? But maybe have to pay attention how they proceed then.

As a first step just taking a JPEG picture would be a good start.

https://developer.android.com/media/camera/camerax/take-photo#java

https://developer.android.com/media/camera/camera2/capture-sessions-requests

Just copy-pasting and correcting errors of cff225e41e/app/src/main/java/com/termux/api/apis/CameraPhotoAPI.java seems to be the most promising.

May have to modify AndroidManifest.xml and provide permissions.

cff225e41e/app/src/main/AndroidManifest.xml

Currently facing:

AndroidManifest.xml:7: error: Error parsing XML: unbound prefix

I forgot:

cff225e41e/app/src/main/AndroidManifest.xml (L3):

xmlns:tools="http://schemas.android.com/tools"

Now have a compilable app but /sdcard/0.jpg is not created. Note that App info > Permissions only mentions Camera, there is nothing related to file access. According to System.getProperty("user.dir") current working directory is /, my idea was to leverage the given app default folder.

Well I based my AndroidManifest.xml on Termux API one but the Termux one seems necessary from the file system access point of view:

image

image

The purpose currently is to have a superset of required permissions that we will be able to minimize afterwards.

find -maxdepth 4 -name 'AndroidManifest.xml'
Output: 
./app/src/main/AndroidManifest.xml
./terminal-view/src/main/AndroidManifest.xml
./termux-shared/src/main/AndroidManifest.xml
./terminal-emulator/src/main/AndroidManifest.xml

./app/src/main/AndroidManifest.xml

does not seem to have any interesting addition.

Should check that we log exceptions correctly and monitor if some are triggered.
