device

I want to scan some device with BLE. I only want to show my device, so for know I get the name of the device and if it is the good one I put it in my list. if (device.getName().contains(DEVICE_NAME)) { mDevices.put(device.hashCode(), device); invalidateOptionsMenu(); } My problem is that if I change the name of my device this check will be false. So I look if it was possible to get some uuid of some services that I add to do the check with something that would not change. And the only way is to connect to the device doing a device.connectGatt(this, false, mGattCallback); and after with the

I recently installed XCode 3.2.4 to my machine. This comes with iOS SDK 4.1. Annoyingly I can no longer install my app to any iPhone. The option to tick "Device" in the drop down for where to install to is present, but when I click it, it doesn't become ticked. Strangely I can only run my app on the simulator, despite the option to select the simulator not being present. Does anyone know how to fix this or what might be the problem? Thanks in advance, Tristan Alrighty, I'm answering my own question. What I didn't realise is that there's seperate build configurations depending on wether you

I have been trying to Set screen resolution for an Array of devices,I have looked all the answers up and from what I understood if I create an res/layout-normal,res/layout-large and so on I can put adjusted Layouts there and the app will Load them automatically. How ever this has not occurred... can someone PLEASE just explain what to do after i have created the layouts and layout folders and allowed the use of all sizes in my XML (although i think the default is all of them). THANK YOU! Its just a example: Device resolution- res/values/dimens.xml(default) res/values-ldpi/dimens.xml (240*320

I want to ask that whether objective C can obtain a unique device ID of the Device. "uniqueIdentifier" is deprecated in iOS7 and I try to use "identifierForVendor" but it gives me a different ID after the app is re-installed. I want to find a stable device ID after the app is re-install, and even the iOS is changed. In the early version of iOS, we can use MAC address to achieve such goal. But now, in iOS7, the MAC address is no longer available. How can i find a stable device ID of the iOS device in iOS7? Maybe using Keychain to store the "identifierForVendor" value is a good approach. But

i'm trying to determine if the device i'm running on has the capability to send/receive phone calls, email, and SMS. i found that i can use the TelephonyManager to get the devices phone number and on devices without the capability of making calls the phone number is null. that's one problem down. i still haven't found a way to detect email and SMS capability. SMS is probably futile without a cell signal, so you can use your same trick for that. As for email (=networking), you can probably iterate through your devices in NetworkInterface.getNetworkInterfaces() and see if the device is connected
