interface FrozenStateChangeCallback

android.os.IBinder.FrozenStateChangeCallback

A callback interface for receiving frozen state change events.

Summary

Constants
static Int	STATE_FROZEN Represents the frozen state of the remote process.
static Int	STATE_UNFROZEN Represents the unfrozen state of the remote process.

Public methods
abstract Unit	onFrozenStateChanged(who: IBinder, state: Int) Interface for receiving a callback when the process hosting an IBinder has changed its frozen state.

Constants

STATE_FROZEN

Added in API level Baklava

static val STATE_FROZEN: Int

Represents the frozen state of the remote process. While in this state, the remote process won't be able to receive and handle a transaction. Therefore, any asynchronous transactions will be buffered and delivered when the process is unfrozen, and any synchronous transactions will result in an error. Buffered transactions may be stale by the time that the process is unfrozen and handles them. To avoid overwhelming the remote process with stale events or overflowing their buffers, it's best to avoid sending binder transactions to a frozen process.

Value: 0

STATE_UNFROZEN

Added in API level Baklava

static val STATE_UNFROZEN: Int

Represents the unfrozen state of the remote process. In this state, the process hosting the object can execute and is not restricted by the freezer from using the CPU or responding to binder transactions.

Value: 1
