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.os.BatteryManager.

func NewManager

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

NewManager obtains android.os.BatteryManager 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) ComputeChargeTimeRemaining

func (m *Manager) ComputeChargeTimeRemaining() (int64, error)

ComputeChargeTimeRemaining calls android.os.BatteryManager.computeChargeTimeRemaining.

func (*Manager) GetIntProperty

func (m *Manager) GetIntProperty(arg0 int32) (int32, error)

GetIntProperty calls android.os.BatteryManager.getIntProperty.

func (*Manager) GetLongProperty

func (m *Manager) GetLongProperty(arg0 int32) (int64, error)

GetLongProperty calls android.os.BatteryManager.getLongProperty.

func (*Manager) GetStringProperty

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

GetStringProperty calls android.os.BatteryManager.getStringProperty.

func (*Manager) IsCharging

func (m *Manager) IsCharging() (bool, error)

IsCharging calls android.os.BatteryManager.isCharging.
