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 if the background does gzip compression, wil

In Android, there are 2 ways to transfer objects, namely, Bundle.putserializable (Key,object) and bundle.putparcelable (key, object) intent. Of course, these object is a certain condition, the former is the implementation of the serializable interface, and the latter is the implementation of the Parcelable interface, the following is an example I do for youFirst we set up a project named: ObjecttestdemoThen

Recently did not want to take two mobile phones, then the old phone on the small call all transferred to the new phone. Can solve the problem of the old mobile phone function is too weak, there is no inconvenience with two mobile phones, although it is a little more to cut the telephone fee, use up or very convenient. But because the trumpet on its own phone is very few, also more than the amount of money to dig.However, the use of the process found a bit of a problem, that is, the inability to
