Functions

func Init

func Init(env *jni.Env) error

Init resolves all JNI class and method references for this package. It is safe to call multiple times (uses sync.Once internally). Exported for E2E testing on Android.

Types

type Manager

type Manager struct {
	VM  *jni.VM
	Ctx *app.Context
	Obj *jni.GlobalRef
}

Manager wraps android.hardware.camera2.CameraManager.

func NewManager

func NewManager(ctx *app.Context) (*Manager, error)

NewManager obtains android.hardware.camera2.CameraManager from the Android system service manager.

func (*Manager) Close

func (m *Manager) Close()

Close releases the global reference to the underlying Java object. After Close, the Manager must not be used.

func (*Manager) GetCameraCharacteristics

func (m *Manager) GetCameraCharacteristics(arg0 string) (*jni.Object, error)

GetCameraCharacteristics calls android.hardware.camera2.CameraManager.getCameraCharacteristics.

func (*Manager) GetCameraDeviceSetup

func (m *Manager) GetCameraDeviceSetup(arg0 string) (*jni.Object, error)

GetCameraDeviceSetup calls android.hardware.camera2.CameraManager.getCameraDeviceSetup.

func (*Manager) GetCameraExtensionCharacteristics

func (m *Manager) GetCameraExtensionCharacteristics(arg0 string) (*jni.Object, error)

GetCameraExtensionCharacteristics calls android.hardware.camera2.CameraManager.getCameraExtensionCharacteristics.

func (*Manager) GetCameraIdList

func (m *Manager) GetCameraIdList() (*jni.Object, error)

GetCameraIdList calls android.hardware.camera2.CameraManager.getCameraIdList.

func (*Manager) GetConcurrentCameraIds

func (m *Manager) GetConcurrentCameraIds() (*jni.Object, error)

GetConcurrentCameraIds calls android.hardware.camera2.CameraManager.getConcurrentCameraIds.

func (*Manager) GetTorchStrengthLevel

func (m *Manager) GetTorchStrengthLevel(arg0 string) (int32, error)

GetTorchStrengthLevel calls android.hardware.camera2.CameraManager.getTorchStrengthLevel.

func (*Manager) IsCameraDeviceSetupSupported

func (m *Manager) IsCameraDeviceSetupSupported(arg0 string) (bool, error)

IsCameraDeviceSetupSupported calls android.hardware.camera2.CameraManager.isCameraDeviceSetupSupported.

func (*Manager) IsConcurrentSessionConfigurationSupported

func (m *Manager) IsConcurrentSessionConfigurationSupported(arg0 *jni.Object) (bool, error)

IsConcurrentSessionConfigurationSupported calls android.hardware.camera2.CameraManager.isConcurrentSessionConfigurationSupported.

func (*Manager) OpenCamera

func (m *Manager) OpenCamera(
	arg0 string,
	arg1 *jni.Object,
	arg2 *jni.Object,
) error

OpenCamera calls android.hardware.camera2.CameraManager.openCamera.

func (*Manager) RegisterAvailabilityCallback

func (m *Manager) RegisterAvailabilityCallback(arg0 *jni.Object, arg1 *jni.Object) error

RegisterAvailabilityCallback calls android.hardware.camera2.CameraManager.registerAvailabilityCallback.

func (*Manager) RegisterTorchCallback

func (m *Manager) RegisterTorchCallback(arg0 *jni.Object, arg1 *jni.Object) error

RegisterTorchCallback calls android.hardware.camera2.CameraManager.registerTorchCallback.

func (*Manager) SetTorchMode

func (m *Manager) SetTorchMode(arg0 string, arg1 bool) error

SetTorchMode calls android.hardware.camera2.CameraManager.setTorchMode.

func (*Manager) TurnOnTorchWithStrengthLevel

func (m *Manager) TurnOnTorchWithStrengthLevel(arg0 string, arg1 int32) error

TurnOnTorchWithStrengthLevel calls android.hardware.camera2.CameraManager.turnOnTorchWithStrengthLevel.

func (*Manager) UnregisterAvailabilityCallback

func (m *Manager) UnregisterAvailabilityCallback(arg0 *jni.Object) error

UnregisterAvailabilityCallback calls android.hardware.camera2.CameraManager.unregisterAvailabilityCallback.

func (*Manager) UnregisterTorchCallback

func (m *Manager) UnregisterTorchCallback(arg0 *jni.Object) error

UnregisterTorchCallback calls android.hardware.camera2.CameraManager.unregisterTorchCallback.
