Until the final v2 release, these things might change, but likely they will not. |

### AndroidX |
|
|
|
|
|
|
|
|
|
The lib was moved to AndroidX classes. Hopefully this should not have any impact on you. |
|
|
|
|
|
|
|
|
|
### Open, not start |
|
|
|
|
|
|
|
|
|
The `start()` method has been renamed to `open()`, and the `stop()` method to `close()`. This was |
|
|
|
|
done for consistency with the `onCameraOpened` callback. |
|
|
|
|
|
|
|
|
|
### Jpeg Quality |
|
|
|
|
|
|
|
|
|
Both `cameraJpegQuality` and `setJpegQuality()` have been removed. They were working only with specific |
|
|
|
|
setups and made no real sense. We will use the default quality provided by the camera engine. |
|
|
|
|
|
|
|
|
|
### Crop Output |
|
|
|
|
|
|
|
|
|
Both `cameraCropOutput` and `setCropOutput()` have been removed. This was an expensive operation that |
|
|
|
|
worked with pictures only. In v2, if you want your output to be cropped to match the view bounds, you |
|
|
|
|
will use the `*snapshot()` APIs (see below). |
|
|
|
|
|
|
|
|
|
### Video Quality |
|
|
|
|
|
|
|
|
|
This was an opaque option packaging various parameters. It has been removed. |
|
|
|
|
You are expected to control the video quality by choosing the video size and setting video parameters |

|

### Session type |
|
|
|
|
|
|
|
|
|
The `SessionType` has been renamed to `Mode` which has a clearer meaning. |
|
|

### Camera Preview |
|
|
|
|
|
|
|
|
|
The type of preview is now configurable with `cameraPreview` XML attribute and `Preview` control class. |
|
|
|
|
This defaults to the new `GL_SURFACE` and it is highly recommended that you do not change this. |

The listener interface brings two breaking signature changes: |

### Experimental mode |
|
|
|
|
|
|
|
|
|
The v2 version introduces a `cameraExperimental` XML flag that you can use to enable experimental features. |
|
|
|
|
Might be used in the future to speed up development. |
|
|
|
|
|
|
|
|
|
### Other improvements & changes |
|
|
|
|
|
|
|
|
|
- Added `@Nullable` and `@NonNull` annotations pretty much everywhere. This might **break** your Kotlin build. |
|
|
|
|
- Added `setGridColor()` and `cameraGridColor` to control the grid color |
|
|
|
|
- Default `Facing` value is not `BACK` anymore but rather a value that guarantees that you have cameras (if possible). |
