code list 5-2. Code List 5-25.2 supports different screens Android devices use two parameters for screen differentiation: size and density. You should think that your app will be installed on screen devices of different sizes and density, so we should include some alternative resources to optimize the appearance of different screen programs. Next we will review the size and density of our screens. Size: Mall, normal, large, xlarge Density: low (ldp

Excellent user experience has three features: fast speed, timely response, and seamless. The following information helps your application implement these features on Android. 1. Fast speed you can't assume that the mobile phone is as fast as the Desktop System and server, but you need to pay more attention to whether your code is efficient. Two principles should be followed for writing efficient

This section describes how to build an android Development Environment Based on Android SDK (2.3) and eclipse (Helios) in windows and create the first application Hello Android world. The specific reference of the small blog: http://blog.sina.com.cn/deabowayOr http://blog.csdn.net/deaboway. Now, we can use eclipse to create and develop

Android is an operating system designed for mobile terminals. It provides security, process management, memory management, network and driver models based on the Linux 2.6 kernel. An android application can be installed on a mobile terminal of the Android system to meet users' requirements for certain functions. It must be supported by the

Chapter 2 androidmanifest. xml file Each Android Application must have an androidmanifest. xml file under the root directory (the file name must be this ). This manifest file lists the required information of the application to the Android system. with this information, the system can run the application (You know Linux ).

Preface The Android platform does not provide specific documentation on how to design and work the Android Application. From the very beginning, Google showed that they had no intention of specifying what Android applications could accept and what they could not. Android al

The Android system framework and upper-layer applications are developed in java (not the Orthodox sun java) and implement their own java Virtual Machine dalvik. Since java Virtual Machine and java are used for development, efficiency is generally considered low. In fact, android is the fastest running speed on basically mainstream smartphone software platforms. W

There are usually two ways to develop Android applications: ndk and eclipse, or add them directly in the android SDK. This section describes how to add an application in the android SDK environment. It involves JNI and Java calls to JNI. The JNI code file is C ++. The first step is to establish the JNI-Layer Code. No

Android development will bring about a new wave of popularity. Many developers have invested in this wave and created many excellent applications. Many developers provide application source projects to contribute their wisdom and creativity. Learning open source code is the best way to master the technology. We recommend several open-source applications. These pr

Long-term Endurance Android simulation environments are used to develop Android applications on PCs. However, the running speed of the two widely used simulated environments is unacceptable (the test environment and data are attached at the end of the article ). Android Simulator The speed of the

Android practice: Android 5.1.1 source code compilation and writing, Most of the friends who bought Nexus mobile phones tried to modify their own systems. In addition to their high cost effectiveness, they are still very popular among developers. I upgraded my 5 prince to the 6.0 preview version, and I was reluctant to switch back to the 5.1 era. However, as the
