The specific analysis is as follows: First, explain the start and shutdown of activity: 1. StartActivity (Intent Intent); Start activityFinish (); End Current Activity2.

In Android, data transmission between images is mainly implemented through the putextra method of intent. The transmitted data structure is a map data (name/value pair, note that the difference is that the basic data type must be used. The following describes the implementation methods through instances. This example describes how to transfer the data of image 1 to Image 2, after Image 2 calculates and proc

Two applications between the value, in fact, the title is too water, the professional argument is "two process how to pass the value", what?! It's not professional enough, okay, you're kinky! "Interprocess communication" is actually more professional, this time you always satisfied! Incidentally, abbreviated to IPC:inter-process communication. Brothers, if you find this article from search engines or other sources, it means that your Android technolog

Android development, in different modules (such as activity) will often have a variety of data need to communicate with each other, commonly used in five ways of delivery. They have their own pros and cons and have their own application scenarios. Here are a few separate sections:1. Intent object passing simple dataThe extra portion of the intent can store the data that is passed, and can transfer some unde

In Android , data transfer betweenActivity is somewhat complex, such as through Intent and bundles and so on, it must be implemented when passing complex objects. Serializable interface classes, which in many cases make it inconvenient to handle data passing between pages. In Javaweb , thesession object to pass data is very practical and convenient, in this, in Android
