Inter-Program communication is one of the best features of Android programs. When a feature already exists in another app and is not a core feature of the program, there is absolutely no need to re-write it.This section describes some common ways to send and receive content between different programs by using intent APIs and Actionprovider objects.Lessons Send a simple data to another

For more information on configur

Quality is critical for an application to be successful in development. Users are asking them to decide that Android applications installed on their devices respond quickly and with reasonable performance. If the application fails to provide useful functionality and a stable user experience, it will be uninstalled quickly. In this article we will introduce ten tricks to quickly improve Android

downloading phonegap, it mainly includes two files: 1. phonegap.0.9.4.jar. the jar file contains the DroidGap class, it encapsulates the Activity and WebView to facilitate packaging. The more main function is to implement multiple Webkit plugins. Through these plugins, you can directly call some android system functions in javascript, such as getting device information such as the screen size, the system v

The performance test simulates various normal, peak, and abnormal load conditions through automated test tools to test the system's performance indicators. And the performance of the app is getting more and more attention, let's introduce the performance test method of the app. However, the performance test is a reference value, and no matter what test method is impossible to accurately test the actual perf

IntroductionToday, Android, iOS, the world, what Tizen, COS blabla are ants, a look at know is to send leadership or to spend research and development funds output products, is not to win the market, for just won the leadership a smile, completely can be ignored.

But the real need to use it to analyze the problem also requires a detailed understanding of how to use and quickly locate the problem.The following will be divided into four parts:The first is th

Mainly introduces some small details of the optimization techniques, although these tips can not be significantly improved application performance, but the appropriate use of these tips and the cumulative effect of the time, for the overall performance of the app is not a small effect. In general, choosing the right algorithm and data structure will be your primary consideration and will not be covered in this article. You should use the tips in this
