How can i shutdown my android device pro-grammatically??Till now i have rooted my android device by SuperonClick v.2.3.3.0 and the rooting is successful.Then i have granted my .apk file superuser permission.Then i have implemented code of executing su file and reboot in my program by
try {
Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", "reboot" });
DataOutputStream os= new DataOutputStream(proc.getOutputStream());
os.writeBytes("/system/bin/-p\n");
os.flush();
} catch (Exception ex) {
ex.printStackTrace();
}
.
But the device is not rebooting and is not shutdown.Please help me out..
Have you set the right permissions in the manifest.xml? Something like
http://developer.android.com/reference/android/Manifest.permission.html#REBOOT
EDIT: have you tried just using the su-command?
Process process = Runtime.getRuntime().exec("su");

I'm a new xamarin developer and this is my first post :)
So, I'm develop a xamarin forms application with prism framework. Everything works in debug mode but in release mode the app crash on start on ios.
This is my OnInitialized function
protected override async void OnInitialized()
{
try
{
InitializeComponent();
if (DataContext.GetContext().CurrentUser == null)
{
if ((await NavigationService.NavigateAsync(nameof(LoginScreen))).Exception is Exception e)
throw e;
}
else
{
if ((await NavigationService.NavigateAsync("NavigationPage/MainScreen")).Exception is Exception e)
throw e;
}
}
catch (Exception ex)
{
Debug.WriteLine($"[ERR] in {nameof(OnInitialized)}");
Debug.WriteLine(ex.Message);
await UserDialogs.Instance.AlertAsync(AppResources.Error_Label);
}
However when I debug in release mode with check "Enable debugging" i catch an exception that said "navigation uri is empty". I dont understand why.
Debug option in release mode
All advice is welcome, thanks in advance
I have done a lot of searching online and I'm not sure what I'm doing wrong. The idea is that I want to launch my iOS app with the following location in a simulator. This works fine when I manually go to debug>location>custom location and set the longitude and latitude....however I need to do it programatically so that my app launches /picks up this location when I click enable locations. Here is my code
public class SampleTest extends SampleBaseTest {
private IOSDriver driver;
private String sessionId;
static UserData sampleUser = null;
#Test(priority = 0)
public void setUp() throws MalformedURLException {
DesiredCapabilities caps = DesiredCapabilities.iphone();
caps.setCapability("appiumVersion", "1.4.16");
caps.setCapability("deviceName","iPhone 6");
caps.setCapability("deviceOrientation", "portrait");
caps.setCapability("platformVersion","9.1");
caps.setCapability("platformName", "iOS");
caps.setCapability("browserName", "");
caps.setCapability("app","sauce-storage:sampleAppe.zip");
URL sauceUrl = new URL("http://" + "sauceUserName" + ":"+ "sauceUserKey" + "#ondemand.saucelabs.com:80/wd/hub");
driver = new IOSDriver(sauceUrl, caps);
Location location = new Location(-8.78319, -114.509, 0.0);
driver.setLocation(location);
sessionId = driver.getSessionId().toString();
#Test(priority = 1)
public void navigateToPayAhead()
throws Exception {
try{
// test logic here
}
catch(Exception e){
e.printStackTrace();
}
}
}
}
Unfortunately, there is a current issue with setting a location on the Sauce iOS simulators. From a support ticket on a similar issue, I was told that it is a known issue, and that it will be addressed (at some point).
I can verify that setting a location does work when using the Android emulators via Sauce Labs.
So, I guess the good news is that you aren't doing anything wrong!
Try adding
caps.setCapability("locationServicesEnabled", true);
caps.setCapability("locationServicesAuthorized", true);
caps.setCapability("bundleId", "YOUR_BUNDLE_ID_HERE");
To get your bundle id, see How to obtain Bundle ID for an IOS App when I have a '.ipa' file for the app installed on my iPAD
I am working on a windows service that works on my development machine, but when I deploy to a test server I find that the Quartz Scheduler I have set up does not work.
There are no exceptions thrown or any clues as to why this is.
Here is my code;
protected override void OnStart(string[] args)
{
try
{
this.SetDailySchedule();
}
catch (SchedulerException ex)
{
this.eventLog.WriteEntry("WMS FM Loader: Schedule Error - " + ex.Message);
throw ex;
}
catch (Exception ex)
{
this.eventLog.WriteEntry("WMS FM Loader: Unexpected Error - " + ex.Message);
throw ex;
}
}
private void SetDailySchedule()
{
this.eventLog.WriteEntry("On Start".Log());
var schedule = this.GetSchedule();
try
{
this.schedFact = new StdSchedulerFactory();
this.sched = this.schedFact.GetScheduler();
}
catch (Exception ex)
{
this.eventLog.WriteEntry(ex.Message.Log());
throw;
}
this.eventLog.WriteEntry(string.Format("Got a scheduler: {0}", schedule).Log());
try
{
ScheduleTheLoad(schedule);
}
catch (Exception ex)
{
this.eventLog.WriteEntry(ex.Message.Log());
throw;
}
this.eventLog.WriteEntry("WMS FM Loader: Scheduler ready");
}
private void ScheduleTheLoad(string schedule)
{
var job = JobBuilder.Create<LoadWorksOrders>().WithIdentity("LoadWorksOrdersJob").Build();
// Trigger the job to run now, and then every day
var trigger =
TriggerBuilder.Create()
.ForJob(job)
.WithIdentity("LoadWorksOrdersTrigger")
.StartNow()
.WithCronSchedule(schedule)
.Build();
this.sched.ScheduleJob(job, trigger);
this.sched.Start();
}
I manually start the service and the event log shows that the scheduler is ready, but LoadWorksOrdersJob doe snot get run.
How should I fix this?
Are you running the two methods in the windows service OnStart? Are you using a service account? Any exceptions in the event viewer/ have you started /stopped the service from services.msc?
I also had this problem. It took me a day to work it out.
For me it was that my assembly had dots/periods in its name. e.g.
Project.UpdateService
When I changed it to...
ProjectUpdateService
... it worked fine. It always worked on the development machine. It just would not work on the remote machine.
UPDATE: It may have been the length of the service that has caused this issue. By removing the dots I shortened the service name. It looks like the maximum length is 25 characters.
I have coded to get the info from the user and send an email of clicking a button. The program is getting executed for a while and then the simulator is crashing showing error
"DE427"-Message queue full... Here's the code that i have done...
if(field==SendMail)
{
Message m = new Message();
Address a = null;
try {
a = new Address("user#xyz.com", "Rahul");
} catch (AddressException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Address[] addresses = {a};
try {
m.addRecipients(net.rim.blackberry.api.mail.Message.RecipientType.TO, addresses);
m.setContent("Name:"+Name.getText().toString()+"\n"+ "Phone :"+Phone.getText().toString()+
"\n"+ "Date & Time:"+DateShow.getText().toString()+"\n"+"Make:"+Make.getText().toString()+
"\n"+"Model:"+Model.getText().toString()+"\n"+"Miles:"+Miles.getText().toString()+"\n");
m.setSubject("Appointment Request (Via Blackberry app)");
} catch (MessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Invoke.invokeApplication(Invoke.APP_TYPE_MESSAGES, new MessageArguments(m));
}
Can anyone tell me what the error is and how to rectify the problem....Plz...
It seems there is an issue with certain versions of Windows XP and the Blackberry simulator version. Check this link http://supportforums.blackberry.com/t5/Testing-and-Deployment/Simulator-quot-device-Error-DE427-quot/m-p/556321
If you clean up the simulator (delete .dmp files from simulator directory) and restart the simulator it works fine
I am writing network application for Blackberry. This code is correct on the simulator but not working on a device. When I run my application on the simulator, my server recieves the message but when I run it on a device, I get an Exception, not IOException, with message "NULL".
try {
byte[] b = msg.getBytes();
dc = (UDPDatagramConnection)Connector.open("datagram://"+getHIP()+":" + getHPort());
Datagram dobject = dc.newDatagram(b, b.length);
dc.send(dobject);
System.out.println("Addr:" + dobject.getAddress());
System.out.println("Well Done!");
} catch (IOException e) {
System.out.println(e.getMessage());
} catch (Exception e) {
System.out.println(e.getMessage());
} finally {
if (dc != null) {
try {
dc.close();
} catch (Exception f) {
System.out.println("Failed to close Connector: " + f);
}
}
}
Network access on the BlackBerry is far from seemless from a developer's point of view. You either have to specify how the connection should be made in the URL, or the device has to have the correct APN settings in Options > Advanced Options > TCP Settings. You could try finding those and entering them to see if it works.
UDP requires the APN to be set in the Connector.open():
(DatagramConnection) Connector.open("udp://<host>:<dest_port>[;<src_port>]/<apn>[|<type>][;tunnelauthusername=<apn username>;tunnelauthpassword=<apn password>]");
For more info on that check out the Connector
It works fine on the simulator w/o APN because the simulator doesn't have an APN, but you need on a real device.
I can think of two possibilities:
UDP is optional in the J2ME spec - so maybe the Blackberry doesn't support it.
The network the device is on might not support it, and the device can detect this, and reports it with an exception.
