how to transfer data from one android device to another

Data transfer between Acticity in AndroidDuring Android development, it is very common to transmit data between different acitifiers. I spent a little time summarizing and recording the data transfer between Acitivity. 1. simple

This article illustrates the method of data transfer between Android implementation activities. Share to everyone for your reference. The specific analysis is as follows: First, explain the start and shutdown of activity: 1. StartActivity (Intent Intent); Start activityFinish (); End Current Activity2. Startactivityforresult (Intent Intent, int requestcode); St

In the previous chapter we review the creation of activity and the life cycle, which we mainly learn about activity jumps and data transfer between activity.First, activity jumps:The simple jump between activity is simply a matter of creating two activity and then using startactivity (intent) to jump and see the code:Intent uio=New Intent (thisactivityclass,activitybclass); startactivity (UiO);What is inte

As we all know, when it comes to developing an Android project, we need to store data in the Data folder of a virtual device when it's about needing access to data, which is the need to interact with it. Before in the relevant books to learn how to upload files to the

In the Android development process, it is very common to pass data between different acitivity. I spent a little time summarizing the data transfer between acitivity and documenting it.1. Simple transfer of key value pairsThis method of delivery is very simple, just need to

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

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

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 implementat

As we all know, when developing an android project, we need to store data in the data folder of the virtual device when it comes to data access and interaction. Previously, I learned how to upload files to devices in related books. As mentioned above, MP3 and MP4 players nee

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
