Android for VS (ii) Visual Studio Android Development instance

Android for VS (i) Visual Studio Android Development instance

Related vs Android development environment installation configuration You can see my previous post

Development and commissioning using VS2010 's own examples

First, the new project

FILE--New project, we chose the blank App (Android) project, such as

　　

Second, the project directory structure

　　

1) androidmanifest.xml

The project configuration profile, the project name, icon, and the permissions required to run the program can be declared here

2) Main.axml

interface layout and element definition files

3) MainActivity.cs

The code that corresponds to the Main.axml file handles the file with the following code:

Using system;using android.app;using android.content;using android.runtime;using android.views;using Android.Widget; Using Android.os;namespace app1{    [Activity (Label = "App1", Mainlauncher = true, Icon = "@drawable/icon")]    public Class mainactivity:activity    {        int count = 1;        protected override void OnCreate (bundle bundle)        {            base. OnCreate (bundle);            Set our view from the "main" layout resource            Setcontentview (Resource.Layout.Main);            Get our buttons from the layout resource,            //and attach a event to it            button button = findviewbyid<button& gt; (Resource.Id.MyButton);            button. Click + = delegate {button. Text = string. Format ("{0} clicks!", count++); };        }    }}

This code is the code for the original instance of VS2010, which implements the simple function of clicking Gay with a twist.

Third, compile option settings

Open the Project Properties page

　　

The three options for application, Android Mainfest, Android option are present in the case of Xamarin installation and configuration success

Android Mainfest in Android SDK tools installation is normal, otherwise it will appear not in the range on the error page

1) compile using Android version

Set the compiled version of the project, generally using the lower version, the option of the version selection list comes from the Android installation list of the SDK

Through my test, if the direct download of Android version extracted to the platforms directory, in the VS this location is not read out. Need to use SDK Manager.exe for Android version update operation, the SDK Manager.exe update need to connect to Google Server, in the country is a wall, can be used to update the proxy server

2) Mininum and Taget

Minimum and target versions can use the compiled version of the settings

Four, start debugging

Add and select the emulator you use before starting debugging, and you can add and select the version you use from the Android emulator toolbar

　　

After selecting the simulator version, you can press F5 to debug, and the version used for debugging must match the version of the compilation option. In the debug phase of the project directory will generate an APK file, this file and Eclipse debug generated files are not the same, eclipse generated files can be sent directly to the mobile phone installation use.

The files here are not allowed, to be published by the VS release operation, the release of an APK file can be placed on the phone to install
