Developers are lazy, it would help to clarify to new people that normal camera permissions actually are required. Specially under the headline permissions.
* Android tap-to-focus and improved (continuous) auto-focus
Tap-to-focus
- On tap, compute focus area around motion event's location, and pass this to the camera parameters
as the new focus area.
- Adds RCTCameraUtils.java file, so far with only a single function that helps compute the focus area
from a motion event. This file can serve as a location for utility constants and functions for the
rest of the app, where such things can be extracted out.
Improved (continuous) auto-focus
- Use FOCUS_MODE_CONTINUOUS_PICTURE/VIDEO when possible to enable continuous auto-focus; fall back to
FOCUS_MODE_AUTO otherwise, if able.
Other changes
- Update README to specify differences between iOS and Android for focus and zoom functionality.
- Update AndroidManifest with more thorough list of permissions and features.
- Update Example package.json react and react-native dependencies to match root package's package.json.
* Example: default empty onFocusChanged callback
- Enables default tap-to-focus behavior in Example app, facilitating
testing of focus features in the Example app
* Update compileSdkVersion to 25 and buildToolsVersion to 25.0.2
Best to keep these up-to-date. Doesn't affect backwards compatibility.
* Add buildToolsVersion requirement of 25.0.2.
* * removed some of the re-parsing of the output image byte array
* removed re-saving of output file
* moved image processing onto an async task to allow camera to be used while processing is running
* added jpeg compression support for android
* move explanation to correct bit of docs
* writing metadata.location (lat and lon coords only) to the exif data... and returning the internal url for the new image (which can be used in conjunction with the RN CameraRoll)
* just a tidy up to remove some duplication and fix some logging (no functional changes)
* oops, fix typo
* docs
* added mediaUri to ios so its the same as android
The API already exposes specific methods for checking camera and microphone access individually. These should be documented. Especially since calling `checkDeviceAuthorizationStatus` requests the microphone permission, which is undesirable in photo-only use cases.
