For continuous integration of Android project construction, you need to build a set of automated compilation and packaging processes, such as building a daily system and automatically generating release files. These require us to have a deep understanding of the compilation and packaging of the android project, such as knowing what each step of the project is done and what environment and tools are needed,

tools folder in the C:/Android-SDK-Windows/platforms/Android-9 directory. In this case, you need to create a new folder, put them in it. At this point, most of the work has been completed, and now you can restart your eclipse, but it will prompt you to update the android plug-in, then you will be OK as prompted. 3. activitymanager: Warning: activity not started

Android IPC Mechanism (4) use ContentProvider for inter-process communication ContentProvider provides a unified interface for data storage and retrieval. It can share data between different applications and is suitable for inter-process communication. The underlying implementation of ContentProvider is also a Binder, but it is much easier to use than AIDL. The s

Write in front:Search on the Internet a lot of installation configuration documents, feel no really with my installation of the process is exactly the same, east and west to gather together, finally is installed, I will not tell you, intermittent, I spent two days time ... One to black screen error is dumbfounded, fortunately in the react Group met enthusiastic peers, and colleagues help ... The nonsense is here, this is just a record of my own loadin

The principle of Android memory management--process managementAndroid takes a different process management strategy from Linux , and unlike Linux, which ends the process after the process activity has stopped, Android keeps the pr

Previously, I briefly described the android startup process at http://blog.csdn.net/codectq/article/details/7383231,but it is not perfect. Now I have encountered some practical problems in the project. In turn, I will read the code and review the android startup process after the kernel is started. The systemserver. cp

In an Android system, the application process is hatched by the zygote process, and the zygote process is initiated by the INIT process. The zygote process creates a Dalvik virtual machine instance at startup, and whenever it hatc

Build the environmental process:1. Install the JDK.See http://www.cnblogs.com/Li-Cheng/p/4334985.html.Note: Essentially download the JDK installation package to the URL and add an environment variable after installation:Java_home, the value is: C:\Program files\java\jdk1.8.0_73 (because the installation path is different, copy from the path), and then add one in the PATH variable:%java_home%\bin;Be sure to remember that all the paths you add in path a

Android Process detailedWhen an application starts, if no other components of the application are already running, then the system launches a new Linux process for the application, which has only one thread, the main thread that we know well. By default, all components of an app run in a process and thread (main). From

you can expose the AIDL interface (MyBinder) to the client through RemoteService ). Now, if the client (such as an Activity) calls bindService () to connect to this server (RemoteService), The onServiceConnected () callback function of the client will obtain the onBind () from the server (RemoteService () the returned MyBinder object. Here we will summarize the writing process of the server: 1. Create a. aidl file: This file (YourInterface. aidl) def

The Android startup process starts with INIT, which is the ancestor process for all subsequent processes. The system startup process can be broadly divided into the following steps1，init.c的启动 挂载目录 初始化 解析配置文件2,init.rc3,在init.rc中app_main中启动了zygote(孵化器)，AndroidRuntime Zygote这个进程是非常重要的一个进程，Zygote进程的建立是真正的

Nowadays, many people want to automate the compilation and packaging of Android projects, such as building a daily system and generating release files automatically. We need to have an in-depth understanding of the compilation and packaging of the android project. At least we need to know what each step of the android project has done and what environment and too

occupies? SHR: Shared memory value used by the process? STAT: The status of the process. where S is dormant, R is executing, z is Zombie, n indicates the process precedence value is negative? %CPU: CPU usage consumed by this process? %MEM: The percentage of physical memory and total memory that the

principals. In general, these trusted organizations have installed their root certificates on your device before the device leaves the factory. Therefore, the digital certificate can ensure that the public key in the digital certificate is indeed the owner of the certificate, or the certificate can be used to confirm the identity of the other party. Digital Certificates are mainly used to solve the security issue of public keys.To sum up, the general proces
