Android Google Map V2 Setting 101

Checkpoint

1. Keystore

1.1 keytool + debug.keystore = SHA1

1.2 SHA1 + Api Console + Package name = keystore

keytool command :

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

Api Console set "Google Maps Android API v2" Service on.

2. Android Play Service

2.1 Install from "Android SDK Manager"

2.2 Include (Project -> Properties -> Android -> Library, Add -> google-play-services_lib)

2.3 Put it into Project's libs directory (google-play-services.jar & android-support-v4.jar)

3. AndroidManifest.xml

3.1 uses-permission (after tag "<manifest>")

3.1.1 <uses-permission android:name="android.permission.INTERNET"/>

3.1.2 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

3.1.3 <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>

3.1.4 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

3.1.5 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
3.1.6 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
3.1.7 <permission

android:name="org.jincheng.map2.permission.MAPS_RECEIVE"

android:protectionLevel="signature"/>

3.2 OpenGL 2.0

3.2.1 <uses-feature android:glEsVersion="0x00020000" android:required="true"/>

3.3 MD5 key (before tag "</application>")

3.3.1 <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="md5_key"/>

Android Google Map (101)

1、Install the Google APIs add-on in Eclipse

2、Android Project

target Google API

Manifest (AndroidManifest.xml)

com.google.android.maps (a child of <application> element)

<uses-library android:name="com.google.android.maps"/>

android.permission.INTERNET (a child of <manifest> element)

<uses-permission android:name="android.permission.INTERNET"/>

@android:style/Theme.NoTitleBar

<activity android:name=".HelloGoogleMaps" android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar">

res/layout/mapview.xml

<?xml version="1.0" encoding="utf-8"?>

<com.google.android.maps.MapView

xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/mapview"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:clickable="true"

android:apiKey="Your Maps API Key goes here"

/>

extends MapActivity

create a object of MapView

setBuiltInZoomControls(true)

override isRouteDisplayed()

3、Obtaining a Maps API Key

debug

~/.android/debug.keystore
keytool -list -alias androiddebugkey -keystore <path_to_debug_keystore>.keystore -storepass android -keypass android

release

keytool -list -alias alias_name -keystore my-release-key.keystore

Use Certificate fingerprint (MD5) to get Map API

Working with XML on Android

Reference : http://www.ibm.com/developerworks/opensource/library/x-android/

在IBM這篇XML的文章中，提供了很好的XML解譯方式

加上小小的修改，成為想要的流程

這樣就可以只要增修 Handler (extends from XmlHandler) 就可處理其他 Xml format
(Entity 好像也應該要變成 Interface or Abstract Object ??)

public interface FeedParser {
 List parse();
}

public abstract class BaseFeedParser implements FeedParser {

 private final URL feedUrl;

 protected BaseFeedParser(String feedUrl){
  try {
   this.feedUrl = new URL(feedUrl);
  } catch (MalformedURLException e) {
   throw new RuntimeException(e);
  }
 }

 protected InputStream getInputStream() {
  try {
      return feedUrl.openConnection().getInputStream();
  } catch (IOException e) {
      throw new RuntimeException(e);
  }
 }
}

public class SaxFeedParser extends BaseFeedParser {

 private XmlHandler handler;
 
 public SaxFeedParser(String feedUrl){
  super(feedUrl);
 }
 
 public List parse() {
     SAXParserFactory factory = SAXParserFactory.newInstance();
     try {
  SAXParser parser = factory.newSAXParser();
  parser.parse(this.getInputStream(), handler);
   
  return handler.getMessages();
  
     } catch (Exception e) {
  throw new RuntimeException(e);
     } 
 }

 public void setHandler(XmlHandler handler) {
  this.handler = handler;
 }
}

public abstract class XmlHandler extends DefaultHandler {

 public abstract List getMessages();
}

iPhone 3D, How to ?

XCode 4.2 中的 template OpenGL ES, 只能表現出 2D 的圖；要有 3D 功能需加入：

(OpenGL ES 1.1 Only)

1、在 EAGLView.h 的 private 區段中宣告
GLuint depthRenderbuffer;

2、在 EAGLView.m 的 createFramebuffer 中加入

glGenRenderbuffersOES(1, &depthRenderbuffer);

glBindRenderbufferOES(GL_RENDERBUFFER_OES, depthRenderbuffer);

glRenderbufferStorageOES(GL_RENDERBUFFER_OES, GL_DEPTH_COMPONENT16_OES,

framebufferWidth, framebufferHeight);

glFramebufferRenderbufferOES(GL_FRAMEBUFFER_OES, GL_DEPTH_ATTACHMENT_OES,

GL_RENDERBUFFER_OES, depthRenderbuffer);

3、在 EAGLView.m 的 deleteFramebuffer 中加入

if(depthRenderbuffer) {

glDeleteRenderbuffersOES(1, &depthRenderbuffer);

depthRenderbuffer = 0;

}

4、3D 的 function 呼叫 (放在 viewController 的 - (void)drawFrame; 中)

glClearColor(0.0f, 0.0f, 0.0f, 1.0f);

glClearDepthf(1.0f);

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

// start drawing 3D objects

glEnable(GL_DEPTH_TEST);

// Projection mode

glMatrixMode(GL_PROJECTION);

glLoadIdentity();

// glOrthof(垂直模式) or glFrustumf(透視模式)

glOrthof(-1.0f, 1.0f, -1.5f, 1.5f, -10.0f, 10.0f);

// tranform the camara for a better view

glTranslatef(0.07f, 0.0f, 0.0f);

glRotatef(-30.0f, 0.0f, 1.0f, 0.0f);

// Model mode

glMatrixMode(GL_MODELVIEW);

// enable GL states for texturing

// this includes cube and 2D instructions and buttons

glEnableClientState(GL_VERTEX_ARRAY);

glEnableClientState(GL_TEXTURE_COORD_ARRAY);

glEnable(GL_TEXTURE_2D);
