use of com.android.systemui.statusbar.policy.KeyButtonView in project android_frameworks_base by crdroidandroid.

the class PhoneStatusBar method handleLongPressBackRecents.

/**
     * This handles long-press of both back and recents.  They are
     * handled together to capture them both being long-pressed
     * at the same time to exit screen pinning (lock task).
     *
     * When accessibility mode is on, only a long-press from recents
     * is required to exit.
     *
     * In all other circumstances we try to pass through long-press events
     * for Back, so that apps can still use it.  Which can be from two things.
     * 1) Not currently in screen pinning (lock task).
     * 2) Back is long-pressed without recents.
