问题描述
我试图把一个装置睡觉,我已经找到references各地有关使用电源管理类的goToSleep(long)方法,但我没有看到它在文档中,当我尝试它不工作在我的code。使用它。
不包含goToSleep方法,我可以看到
我的code:
私人无效sleepDevice(){
尝试{
电源管理powerMgr =(电源管理)getSystemService(Context.POWER_SERVICE);
时间长= 1000;
powerMgr.goToSleep(时间);
}赶上(例外前){
updateStatus(错误尝试重新启动设备。);
updateStatus(ex.getLocalizedMessage());
}
}
Android的工作室不让code与消息编译,无法解析法'goToSleep(长)。
我甚至不看此方法,因为pcated德$ P $。另外,我并不需要担心安全权限,呼叫打算在扎根设备上运行或无根设备优雅失败。
您可以使用DeviceAdministrator,但你需要的用户授予的权利。
I am attempting to put a device to sleep and I have found references all over about using the PowerManager class's goToSleep(long) method but I do not see it in the documentation and it does not work when I attempt to using it in my code.
Android's documentation does not contain a goToSleep method that I could see.
My Code:
private void sleepDevice() {
try {
PowerManager powerMgr = (PowerManager) getSystemService(Context.POWER_SERVICE);
long time = 1000;
powerMgr.goToSleep(time);
} catch (Exception ex) {
updateStatus("Error attempting to reboot device.");
updateStatus(ex.getLocalizedMessage());
}
}
Android Studio does not let the code compile with the message, "Cannot resolve method 'goToSleep(long).
I don't even see this method as deprecated. Also, I don't need to worry about security permissions, the call is intended to run on rooted devices or fail elegantly on non-rooted devices.
You can use the DeviceAdministrator , but you need the user to grant you those rights.
