Android uses SharedPreferences to store and read data Most of the time, the software we develop needs to provide users with the software parameter setting function, such as our commonly used QQ, users can set whether to allow strangers to add themselves as friends. For saving software configuration parameters, if the window software is used, we usually use the INI file for saving. If it is a j2se applicatio

I. Introduction of Sharedpreferences(1) sharedpreferences is a lightweight storage class on the Android platform that holds some of the most common configurations of the app, such as activity status, when activity is paused,Saves the state of this activity to sharedpereferences, and when the activity is overloaded, the system callback method Onsaveinstancestate, and then takes the value out of the sharedpreferences.(2) Sharedpreferences provides the J

Before learning Android to submit data to the PHP server did not succeed, after watching the video for two or three weeks, now finally realize the interaction with the server. Although the completion is not the PHP side, but in this process has learned a lot of things. Now let me show you my chart of achievement.The idea is that there is a data in the server-side

1.JSON (JavaScript Object Notation) is a lightweight data interchange format. It is based on a subset of JavaScript (standard ECMA-262 3rd edition-december 1999). JSON takes a completely language-independent text format, but also uses a similar idiom to the C language family (c, C + +, C #, Java, JavaScript, Perl, Python, etc.). These features make JSON an ideal data exchange language. Easy to read and writ

The Android system provides a system-level Configuration Storage scheme for applications, which is implemented by the Sharedpreferences interface, where all the information stored in the interface is saved in the form of a name-value pair, but its data types are limited to basic data types such as strings, shapes, booleans, and so on. These configurations are eve

Exercise caution when developing a UDP data transmission system between Android phones TIPS:1. The communication between mobile UDP and a fixed IP is not a big problem, but it may also cause a slight packet loss. The problem cannot be found here. Do you think there are special considerations for UDP implementation at the android network layer.2. UDP communication
