  • Android: Communication with host computer

    - by dannyn382
    I am looking for ideas as to how all of you can think to solve this issue. I am going to be using an Android Tablet as basically a touch screen input for a project. I need to be able to control servos and solenoids and such, so I will be using a Raspberry Pi to do this. I am looking for ideas on how to get the tablet and the Raspberry Pi to talk. Here are a few that I have though of so far. Use Wifi (which I really do not want to, Ethernet would be okay) to ssh into the Raspberry Pi (with an external library) and run scripts that way from the Android app. Use a com port for Android (maybe Andropod if there hardware becomes available?) and run scripts on the Raspberry Pi. Those are probably two of the "best" ideas that I can think of for now. Can anyone think of any other "better" ideas? Thanks in advance for the help, Dan

Any ideas?

  • CADisplayLink stops updating when UIScrollView scrolled

    - by Tricky
    Title is quite self explanatory, but I have some animation being done in a loop triggered by CADisplayLink. However, as soon as I scroll a UIScrollView I have added to my view hierarchy, the animation stops immediately, only to return again when scrolling has completely stopped and come to a standstill.... Anyway to cancel this behaviour?

    - by dooonot
    I just started to use Storyboard in Xcode. I have a starting view that has some buttons inside. Is there a way to load a special view when a button is clicked? I only found this workaround: -(IBAction)loadRegistration:(id)sender { // load registration controller UIStoryboard *storyboard = self.storyboard; RegisterController *svc = [storyboard instantiateViewControllerWithIdentifier:@"RegisterController"]; [self presentViewController:svc animated:YES completion:nil]; }

    - by Moshik
    Hi, i need to share data between a local service and his hosting activity, i`am using sendBroadcast in order to send data to the hosting activity from the service, but if i want to send data back to the service from the hosting activity? so i though to create static method on the service, and call from the activity, and through it send the parameter, but then i cant do operations like toast inside that static method(which is inside the service).. coz you cant use "myclass.this" inside a static method, i guess there r more limits.. mybe another solution? mybe there is a proper way for this task? thanks, moshik.

  • iPhone: How to run a Beta build, in addition to the App Store build?

    - by rondoagogo
    Hi, All! I have an app on the Store for which we’re readying an update. The other members of our team have the App Store version already loaded up (~purchased) on their respective iPhones -- and those contain User Data which each member needs to be able to keep. In the meantime, we need to test out a Beta version of the next version of the app. Presumably, we’d need to have the two versions (ad hoc, and app store) co-existing on each device, at least until everyone’s signed off on the beta, and it’s uploaded to the store (at which point, they'd delete the beta version). [Once it’s on the Store, of course, they can each update their main (i.e., Release) version of the app via the usual App Store 'update' mechanism -- and then delete the beta version from their devices. In that case, all their user data is still retained intact.] So assuming that’s the proper workflow ... How do I issue a Beta to the team, and have it not replace/overwrite the existing App Store version? I’ve tried customizing parameters in the beta’s “[appname]-Info.plist”, but haven’t found a setting yet that allows the two versions (beta and release) to co-exist on the same device. Any ideas? And is this this is the proper approach to them being able to keep their data? (And last, how might I do it with & without a script? I assume there's just one parameter that'd need to be changed.) I hope this all makes sense -- thank you in advance for your help!

  • From iPhone to Android Question

    - by BahaiResearch.com
    (I'm coming from an iPhone dev world. ) In Android do we need to worry what OS version we compile against? In the iPhone world I would usually target a release that's at least 6 months old to limit the number of issues with installing on iPhones with old OSs. What strategy should I use when choosing what to compile against on the Android?

  • Is there a way to automatically update application on Android?

    - by Levara
    Hi, I'm developing an application that will most likely be preinstalled on devices. It will be also available on Market. Is there a way to update those instances that are not downloaded through Market, since Market won't notify users about an update. I was thinking about, as suggested here, trying to contact my site periodically, and when update is available, download it. I'm wondering if there is a way to do this update automatically, so that user doesn't have to do anything (like running the package manually). Or, when my site shows update is available, to offer users an update through Market, even though it's not installed through Market. Thanks!

  • The delegate method "clickedButtonAtIndex:" is not called.

    - by sagiftw
    Hello everyone! I have created an alert view with two buttons using the following code: UIAlertView *alertView = [[UIAlertView alloc] initWithTitle: title message: msg delegate:nil cancelButtonTitle:@"Replay" otherButtonTitles:@"Highscore", nil]; [alertView show]; I want to run some code when one of the buttons is clicked. In order to do so, I have added the following method to the delegate.m file: - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex==0) //Run some code else //Other code } But this method is not called when I press either of the buttons! Can someone tell me why? Thanks in advance, Sagiftw
