how to transfer data from android to iphone

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 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

The current Android Access interface transmits data more in JSON format (simple and easy to parse across platforms), in order to save bandwidth and transfer time the server will often be gzip compressed before transmission, here are a few points to note. 1. For PHP server, the interface must be in the header with parameters Accept-encoding:gzip, deflate, or even

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

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

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

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 pre

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
