Some books introduce and explain the service components of Android, using the term backend services, and are relative to the activity running on the main thread. Because the word backstage is easily misunderstood, the service has been running in the background? What thread is running? Service has always been a thread running? and backstage in different contexts have different understanding. But if you've developed a

1. The activation process of the child activity component within the processIn the startup process of the Android activity component http://blog.csdn.net/jltxgcy/article/details/35984557, we have analyzed the activation process of the activity in detail, We only analyze the differences between the child activity compon

dex on the C layer, you can call the main Java method to execute Java code. However, if you want to access system services, no Context is acceptable. Therefore, ActivityThread is called through reflection, get the Application.My initial thought was to inject inj_dalvik into the system_server process, and then access all Android system services in it. But then I found two problems, dex cannot use a remote s

between processes in android: Activity, content provider, binder, service In fact, the android process communication is based on linux. Although the names are slightly different, the underlying implementation is implemented in the above four methods. 1. Activity implements value transfer between two apps Suppose there are two apps, APP1 and APP2, and you want to

Original article: Android calls the JNI process to facilitate subsequent operations. I personally recorded the entire process of calling JNI, and I forgot to save it. Ah. In some cases, the ndk environment and ndk source code must be prepared. cygwin must be installed with a profile. Java requires environment variables. 1. Create a new project and create a cl

Use of Android process-to-process communication AIDL: 1. Introduction In Android, threads cannot transmit information to each other and share their memory space. Therefore, Android provides AIDL. AIDL (Android Interface Definition

The Android system is actually an application in a Linux system. The corresponding program is app_process, and the program is declared in Init.rc. Linux starts the zygote (app_process) session, which is implemented by Java code and executed by the Dalvik virtual machine, and the corresponding code is latest-android-2.3.7_r1\android-2.3.7_r1\ In Frameworks\base\co

invalidate () operation is as follows:1. setvisibility () method:The requestlayout () and invalidate methods are called indirectly when the visual status of a view is changed from invisible to gone. At the same time, because the size of the entire view tree has changed, the measure () process and the draw () process will be requested. Similarly, only the view that needs to be "re-drawn" will be drawn.Descr

For Android Developers, ANR (Application Not Responding) is a common problem. Generally, if an ANR occurs, the system generates a trace file in the/data/anr/directory. By analyzing the trace file, you can locate the cause of the ANR. There are many reasons for the generation of ANR, such as CPU usage is too high, events are not responded to in a timely manner, deadlocks, etc. Next we will solve the ANR problem caused by deadlocks, to describe how to a
