Defects in Wi-Fi fast transfer verification of Jinshan kubernetes for Android Bugs in the process, non-technical issues, non-trivial flow, not awesome. Kingsoft kubernetes comes with the wifi fast transfer function. When this function is enabled, port 1080 is opened on the mobile phone. You can access port 1080 in a pc browser in the same LAN and a webpage is obt

For Android, passing complex types is primarily about converting its own class into a base byte array, and passing data between the activity is accomplished through intent. There are two main methods of the Android serialization object, which is to implement the serializable interface, or implement the Parcelable interface. The implementation of the serializable interface is supported by the Java SE itself,

wasThis is the main code in the first activityThe code for the second activity isEdit without any errors, but run the program, the following interface appearsWhen you click the Calculate button, the following conditions occur:Check for Logcat hints in eclipseThe reason for the error is probably that an activity parameter is not passed to the second activity, causing the second activity to receive a null parameter, and then cause the program to run an error, after its own careful check out, the

1. Data transfer of Interface jump(1) intent.setdata ()---Intent.getdata ();The data passed is relatively simple, usually a literal type of data string; If we pass on data that is more complex (several types), or longer, this method is less practical. (2) If there are a lot of different types of data passingIntent.putextra (key, value);• Basic types of data can be passed, and arrays of basic type data can be passed• The object must be an object that i

In the project, the inevitable to two pages between the data transfer, even if not delivery, but also need to be refreshed and so on, we are based on the Library class method provided by Google, but also can do, mainly broadcast broadcastreceiver, StartActivity methods or application instances and so on, are all working (as long as the implementation is good, after all, the function implementation takes precedence over the code structure?). ）。But at t

Years ago, I studied how Android can implement the Wireless Data Transfer Function and wrote a demo. I have nothing to do with it recently. I want to sort it out and share it with you. Early research found that Android has the following technologies to achieve wireless data transfer: 1. Bluetooth has been used for a lo

In development, we often use the activity, then since the use of activity, it is inevitable to pass data between the two activity. Here we first talk about the principle, look at the code and examples.Situation A: We need to start and pass data from Activity_1 to activity_2,activity_2 only to receive data from Activity_1, but not for other operations.Case B: We need to start activity_2 from Activity_1, and want Activity_2 to pass the data to Activity_1 when it is destroyed.First of all, let's sa

There are two ways to pass data between Fragment and activity, one is to use setargument and one is to use an interface callback. Learn the first method below.(1) using the Setargument method:For the sake of understanding, I am here to make a metaphor: if the activity is the emperor, it set up three departments (such as the three provinces six), respectively, Fragment1,fragment2 and Fragemnt3;Now he will command the department Fragment1 to do something, such as: "lead the Army to attack the isla

In Android, activity is an interface that requires intent (intent) for message delivery when it is necessary to switch between interfaces. Use the startactivity (Intent) function to start another activity.Bundle is a Key-value class that can carry information with him.The bundle.putstring ("Key", "String") method and the Bundle.getstring ("key") method are put in and out of the information.The information can be put into intent, using the method Inten
