Moconews published an article in March 25 saying that the reason why so many operators and mobile phone manufacturers are willing to launch Android devices is that Google will return part of the advertising revenue generated by these devices to operators and mobile phone manufacturers., as long as mobile phone manufacturers and operators are willing to build Google applications (Google Maps, Gmail, YouTube, Google buzz, and Google shopper) into their

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

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

　　Activity transmits data to the broadcast receiver simply by put the data into the intent before sending the broadcast.How does a broadcast receiver transmit data to the activity? The interface is used here, by defining an interface in the broadcast receiver, and then the activity that receives the broadcast receiver data implements the interface. First look at the chestnut below, the activity sends a broadcast, and then the broadcast receiver returns a string.Activity layout File1 XML version=

For Android, passing complex types is primarily about converting its own class into a base byte array, and passing data between the activity is accomplished through intent. There are two main methods of the Android serialization object, which is to implement the serializable interface, or implement the Parcelable interface. The implementation of the serializable interface is supported by the Java SE itself,

I've written a similar tool for the Android system's cropped image. The feature was largely implemented, but left a call question: How do I invoke the cropping tool from my program and get the cropped picture? In fact, this is also very simple, is the basic use of intent. First image (the interface is still not optimized, unsightly ugly bar): Start activity, open Picture Selection window, choose a picture randomly Here is the jump to the croppin

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

This article illustrates the application setting of global variables and the use of values for Android programming. Share to everyone for your reference, specific as follows: /** * Rewrite application, mainly rewrite the OnCreate method inside, that is, when created, * We let it initialize some of the values that we saw in Javaeye some time ago, similar to this, * I made some improvements.
