entrypoint of android application

落爺英雄遲暮 提交于 2019-12-03 12:38:28
When we develop an Android application, we always start from the onCreate() method of the main activity. It is obvious that there are some initializations that should be done before calling onCreate() . My question is: what is the entrypoint point (or the main method) of an Android application? What does the Dalvik VM invoke in the very beginning (i.e., when it finishes initialization of its own, and is about to transfer control to the application)? Where can I find the code of this main ? stefan bachert The first "entry" point is the application class as Kingston pointed out. However, the

Browser sending “Dalvik” as user agent

Android Browsers is sending Dalvik as the user agents in the request headers. I am currently working on a mobile site having a simple login page that validates username and password then authorizes users profile. But when i checked the request headers i saw something unusual, there were two user agents from the same device. Following are the user-agents from the same device: "Mozilla/5.0 (Linux; Android 4.1.2; C5303 Build/12.0.A.1.257) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.114 Mobile Safari/537.36" "Dalvik/1.6.0 (Linux; U; Android 4.2.2; C2004 Build/15.2.A.2.5)" Even

On Android how do I make oddly shaped clipping areas?

南楼画角 提交于 2019-12-03 10:04:41
Here is how to create a clipping area the shape of a circle: Path path = new Path(); path.addCircle(200,200,100,Direction.CW); c.clipPath(path); // c is a Canvas Now there's a clipping area on the Canvas which prevents drawing anything outside the bounds of that circle. But, what if I want to have the clipping area be shaped like a donut (or whatever)? I tried playing around with creating a second Path and using toggleInverseFillType on it and then adding that to the original path, but that doesn't seem to work. Alternatively, instead of using a Path, is it possible to just create a Bitmap to

Conversion to Dalvik format failed with error 1 with a scary message in the Console view

I've seen a few questions with this topic, but when I search for the other part I have in my error, I don't find anything, so I decided to post a question with the full explanation. No errors are recognized in my code. Nowhere. All libraries are added, external library projects are successfully linked. There is no indication that anything should go wrong with a launch. Yet, when I launch the application - Run, compile and build (automatically) - I get a pop up message stating that my project contains error(s) and that I should please fix them before attempting to launch the application again.

Dalvik VM & Java Memory Model (Concurrent programming on Android)

狂风中的少年 提交于 2019-12-03 01:19:30
问题 I am working on Android projects which involve the lot of concurrent programming and I am going to implement some custom inter-threads communication stuff (the one from java.util.concurent are not well suited for my purposes). The concurrent programming is not easy in general but with Dalvik it seems to be even harder. To get the correct code you should know some specific things and that where problem arise with Dalvik. I just can't find a detailed documentation about the Dalvik VM. Most
