问题 Question related to Android for Work . My application was a device Admin privileged app and now I have modified the code which creates a managed work profile and sets itself as the profile owner. The question is, if I upgrade my application, it becomes a profile owner from device admin. Now there will be two copies of my application, one outside the profile and one inside (badged version). Is there a way if I need to transfer some data from the personal space app to the work profile app

Closed 5 months ago . With the release of iOS 13, iOS NFC core framework has added API's to write on NFC tags. But does this mean that now we can transfer data between two iPhone devices using NFC APIs. Writing and reading on NFC tags works fine. 回答1: Not directly between two phones. You can read from

问题 I have a very strange issue, which has been driving me mad for the last two days. I have a serial device (LS 100 Photometer) which I am trying to control. Using a terminal (termite) set up with the correct parameters, I can send the command ("MES"), followed by the delimeter (CR LF), and I get back some measurement data as expected. The problem is, from Qt, I do not get any data returned. Using a sniffer program, I have confirmed that I am sending the exact same 5 bytes (MES CR LF) as the

问题 I am trying to transfer data from S3 to GCS by using a Java client but I got this error. Failed to obtain the location of the Google Cloud Storage (GCS) bucket ___ due to insufficient permissions. Please verify that the necessary permissions have been granted. I am using a service account with the Project Owner role, which should grant unlimited access to all project resources. 回答1: Google Transfer Service is using an internal service account to move the data back and forth. This account is

问题 Preferably, this would be a computer connected via cable, but if there's a way to do it over wifi then this would also be useful. I'm wondering if it's possible to send messages between them? Or if i had a mac app and an iPhone app, could I communicate between them over wifi or a usb connection, rather than using a server or something? 回答1: Connecting over WiFi is possible, cable connection however isn't possible (certainly not in the documented API) unless the phone is jailbroken. For wifi

问题 I am currently implementing an iOS application that uses CoreBluetooth to transfer data between 2 devices. For example, to send data from the central to the peripheral, I use this code: NSData *data = [NSJSONSerialization dataWithJSONObject:dictionary options:NSJSONWritingPrettyPrinted error:nil]; NSLog(@"Writing data of length %d", [data length]); [peripheral writeValue:data forCharacteristic:characteristic type:CBCharacteristicWriteWithResponse]; This works absolutely fine, but the thing is

问题 Here is an example of opening a UDP socket in a Mininet host and writing the received packets to a file. h1 acts as a server and h2 acts as a client which is supposed to send a message ( for example "Hello world") to h1. h1 is suppose to receive this message and store the message and address in foo.txt file. But after implementing this code, although foo.txt is created but it's empty and does not contain any data or information. What's wrong? mininetSocketTest.py: #!/usr/bin/python from

问题 Does PHP have global variables that can be modified by one running script and read by another? 回答1: No, by design PHP is a "share nothing" architecture, which means nothing is shared between processes running at the same time or between requests running one after another. There are ways to share data, but you have to do it explicitly. If you just want to share between 2 requests from the same user, sessions or cookies might be the way to go. If you want to share between multiple users, you
