checks the permissions of the given URI and passes the request to the content provider for registration. The content provider can understand what the URI wants. The Urimatcher class is used to help group parse URIs. The main methods to be implemented are as follows: query(Uri, String[], String, String[], String)Returns data to the caller insert(Uri, ContentValues)Inserting data into a co

Although the use of hand-tour for example, but applicable to any native C + + NDK compilation method.1. first talk about the project background, COCOS2DX hand tour, development generally in Windows vs under the development of debugging,IOS using Xcode can also be very convenient debugging, but Android is not so lucky, general debugging rely on log to analyze the problem, always feel inefficient. Debugging native

to see the class definition:See here, found that the third-party JSON parsing package has been used, the annotation directly resolves the field values. But we search this class globally, tracking is too troublesome, here is another way to track the code, that is, using xposed to intercept the constructor of this class, and then internally print the stack information to see the method call path, this method I have used before. This article is able to

A good application software requires good maintenance. From the initial publication to the final product, this process requires constant updates of the version. So how can users get the latest application installation package immediately? Therefore, we need to upgrade the module from the first version. The implementation principle of the automatic update function is that we negotiate an interface with the background in advance. We access this interface in the main Activity of the application. If

How Android is developed to ensure service is not killed (Broadcast+system/app)PrefaceRecent projects to achieve such an effect: After running, to have a service is always running in the background, regardless of what the user does to ensure that the service is not killed, this is really a problem.

Top 10 tips to optimize Android App Performance No matter whether the hammer or eggplant mobile phone keeps popping up, the mobile phone market share of the Android system is still the largest, so the number of apps developed based on Android is also very large. So how can we develop a higher-performance

Graduation design is to do the topic of smart home, to do a mobile phone Bluetooth app, and the next computer to achieve data transmission; I've never done Android before, but I'm pretty good with qt,c++, so I use eclipse to feel quite handy, and the Java language is very similar to C + + in many places, so I personally feel , C + + people, Java is certainly not

the uncompressed data in the APK file to be aligned on a 4-byte boundary (4 bytes is a well-performing value) so that the Android system can read the file using the Mmap () function (see the purpose of the function itself) to get higher performance on read resources ，Ps:1. Alignment on a 4-byte boundary means that, in general, the compiler bar 4 bytes are read as a unit, so that the CPU can access the vari
