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 MediaProjection

type MediaProjection struct {
	VM  *jni.VM
	Obj *jni.GlobalRef
}

MediaProjection wraps android.media.projection.MediaProjection.

func (*MediaProjection) Stop

func (m *MediaProjection) Stop() error

Stop calls android.media.projection.MediaProjection.stop.

func (*MediaProjection) UnregisterCallback

func (m *MediaProjection) UnregisterCallback(arg0 *jni.Object) error

UnregisterCallback calls android.media.projection.MediaProjection.unregisterCallback.

type MediaProjectionManager

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

MediaProjectionManager wraps android.media.projection.MediaProjectionManager.

func NewMediaProjectionManager

func NewMediaProjectionManager(ctx *app.Context) (*MediaProjectionManager, error)

NewMediaProjectionManager obtains android.media.projection.MediaProjectionManager from the Android system service manager.

func (*MediaProjectionManager) Close

func (m *MediaProjectionManager) Close()

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

func (*MediaProjectionManager) CreateScreenCaptureIntent0

func (m *MediaProjectionManager) CreateScreenCaptureIntent0() (*jni.Object, error)

CreateScreenCaptureIntent0 calls android.media.projection.MediaProjectionManager.createScreenCaptureIntent.

func (*MediaProjectionManager) CreateScreenCaptureIntent1_1

func (m *MediaProjectionManager) CreateScreenCaptureIntent1_1(arg0 *jni.Object) (*jni.Object, error)

CreateScreenCaptureIntent1_1 calls android.media.projection.MediaProjectionManager.createScreenCaptureIntent.

func (*MediaProjectionManager) GetMediaProjection

func (m *MediaProjectionManager) GetMediaProjection(arg0 int32, arg1 *jni.Object) (*jni.Object, error)

GetMediaProjection calls android.media.projection.MediaProjectionManager.getMediaProjection.

type VirtualDisplay

type VirtualDisplay struct {
	VM  *jni.VM
	Obj *jni.GlobalRef
}

VirtualDisplay wraps android.hardware.display.VirtualDisplay.

func (*VirtualDisplay) GetDisplay

func (m *VirtualDisplay) GetDisplay() (*jni.Object, error)

GetDisplay calls android.hardware.display.VirtualDisplay.getDisplay.

func (*VirtualDisplay) GetSurface

func (m *VirtualDisplay) GetSurface() (*jni.Object, error)

GetSurface calls android.hardware.display.VirtualDisplay.getSurface.

func (*VirtualDisplay) Release

func (m *VirtualDisplay) Release() error

Release calls android.hardware.display.VirtualDisplay.release.

func (*VirtualDisplay) Resize

func (m *VirtualDisplay) Resize(
	arg0 int32,
	arg1 int32,
	arg2 int32,
) error

Resize calls android.hardware.display.VirtualDisplay.resize.

func (*VirtualDisplay) SetRotation

func (m *VirtualDisplay) SetRotation(arg0 int32) error

SetRotation calls android.hardware.display.VirtualDisplay.setRotation.

func (*VirtualDisplay) SetSurface

func (m *VirtualDisplay) SetSurface(arg0 *jni.Object) error

SetSurface calls android.hardware.display.VirtualDisplay.setSurface.

func (*VirtualDisplay) ToString

func (m *VirtualDisplay) ToString() (string, error)

ToString calls android.hardware.display.VirtualDisplay.toString.
