To put it bluntly, the web app uses webview for development. If you have time, you must take a good look at this document. The more you lea
Why do Android apps use MulticastSocket to listen for multicast? Why do they connect to different routes and run on different mobile phones? Some of them cannot receive multicast messages.

In Android app development, there are occasional exceptions that cause the app being used to be abnormal and forced to shut down, which leads to an unfriendly user experience. To solve this problem, we need to catch the exception and do the processing. There are two kinds of exceptions in Java, namely error and RuntimeException, the former do not need us to deal with, we often deal with the latter. So how do you catch the exception of threads at run t

memory leak.(2) PSS information for totalThis value is the amount of memory your app really occupies, and with this information, you can easily identify which programs in your phone are more memory-heavy.4. SummaryAbout the use of memory in the development of Android and memory leak detection simply introduced here, basically in the above three ways can be located in the memory leak problem, usually in the use of bitmap, database and JNI layer C/D +
why, but since know this piece of code so good to run. That is to get the packageparser.package through reflection and then encapsulate it into intentfilter. Solution: Directly on the code. Because it's all just a reflection and rewriting the code once. try {//Get parse Class Packageparser and instantiate class Packageparserclass = Class.forName ("Android.content.pm.PackageParser"); Object Packageparser = Packageparserclass.getconstructor (String.class). newinstance (Dexpath); Build parame

Raspberry Pi Home for your friends to collect the following several mobile phone apps, with these software, in your playing Raspberry Pi process, will play a powerful effect.Because many of the software is Google Play, and in the celestial world we can not use Google's services, so the software has been uploaded to Baidu network disk, convenient for everyone to download.1.

In Android, data is exposed and received across apps.
For example, a small project is used to add words in a single word base.
Function: data is exposed and received across apps in different ways.Exposed app: adds, deletes, modifies, and queries words (Word, and Translate;Acceptor app: fuzzy query to obtain the data of the exposed end.

policy.Scenario: If the software starts each time to read the skin files on the SD card, the speed will be slower. A good practice is to provide a skin settings interface, the user chose which skin, the skin file extracted to the "/data/data/[package Name]/skin" path, so that does not need to read across the memory, faster, And do not need to go to the zip archive every time to read, do not rely on the SD card files, even if the skin compression package files are deleted is not related.Implemen
