Athread is the Activitythread instance that the activity is applied to. Since activity is created and attach in Activitythread, this parameter is this. InStr: This type of translation came to the "detection instrument", more difficult to understand what the meaning. However, in startactivity, it is used to send requests to AMS, which should be a tool class for interaction between the application and the system service, which assigns it to the instrum

. Manually new components are just a common object and are useless. Can we declare an activity in AndroidManifest. xml first, and then all the activities in our plug-in will be executed through it? The idea is a bit bold, but there is no way, because we can think of so much now. Now that you want to use an activity to restore the soul, you must understand the startup principle of the activity. Otherwise, everything is really empty talk. Through our previous study, we noticed that when an activit

A netizen's database is deployed in a windows environment. It may be due to storage problems or windows file system problems. After I/O problems occur, the database cannot be started after it is restarted, when an error is reported, several files cannot be read.

It may take some time to learn about AmS. In summary, you can also sort out your own ideas. I am a small soldier. I don't understand it in some places. Can we discuss and communicate with each other to make progress ~~~ AmS is one of the core modules of the Android upper-layer system. It mainly manages the lifecycle of application processes and activities, services, Broadcast, and providers of processes. F

). Normally, AMS calls this interface in two cases: Click the application icon to open a new application; When Activity B returns activity A, Activity A is killed due to insufficient memory. As for how AMS determines when to call this interface, it is the internal scheduling process of AMS for the activity, which will be analyzed later. The following describes t

But two questions need to be clarified beforehand:Who is responsible for managing activity?The Android framework uses the C/s

android:process= ": remote", represented in the application, when the service is needed, a new process is automatically created. And if it is android:process= "remote", there is no ":" semicolon, then the global process is created, and the process is shared by different applications.Original address: http://www.cnblogs.com/franksunny/archive/2012/04/17/2453403.htmlVery want to find out the relationship between starting an Activity and task (Task), there are a lot of relevant information on the I

Attack Android injection 5In Android, almost all IPC communication is through the Binder. It can be said that the Binder occupies a very important position in Android. IPC communication generally involves two parts: client and server. on Android, all the serivce parts of the Binder are collectively referred to as NativeService (which is different from what is usually called the Service component ), A NativeService can communicate with multiple clients. If you want to learn more about this, you c

that AMS can eliminate the MIDlet at any time, And the MIDlet can also enter a pause state and be activated again. The MIDlet state can be divided into three types: paused, active, and destroyed. When AMS creates a new MIDlet object, it corresponds to the MIDlet, and its constructor is called and enters the paused state. After all the preparations are completed, AMS
