Android: Your First App! WoB Wrapper
Prerequisites:
Java JRE:
http://www.oracle.com/technetwork/java/javase/downloads/index.html
Android SDK(Follow guide and install Eclipse + ADT):
http://developer.android.com/sdk/installing.html
Ok, so I am going to assume if your reading this you've installed the Java JRE, Eclipse, ADT, and have a copy of the latest android SDK on hand!
Step 1:
Fire up Eclipse and wait for it to fully load. Once loaded click File -> New Android Project.
Step 2:
Fill out all the information here.
Project Name: WoB Wrapper
Build Target: Android 2.2 (I picked this since its the latest sdk.. you can use the google ones if you want to add maps/what not)
Application Name: World of Bleach Wrapper
Package Name: my420Time.Wob_Wrapper
Create Activity: Main
Min SDK Version: 3
-> Finish
Step 3:
Now navigate to our newly created package and expand res -> layout -> main.xml. Paste the code below into Main.xml. All we are doing here is setting up a basic web gui. Android is awesome about making things easy!
Step 4:
Now navigate to our package and expand src -> my420time.Wob_Wrapper -> Main.java. Paste the code below into your Main.java file.
Step 5:
Navigate to AndroidManifest.xml and paste the code below to tell our application we need access to the internet!
Step 6:
Right click "WoB Wrapper" (The project) and click Run As -> Android Application. Congrats you've written your first android application! (You can also have it save a signed/unsigned apk for the market/your phone)

Now navigate to our newly created package and expand res -> layout -> main.xml. Paste the code below into Main.xml. All we are doing here is setting up a basic web gui. Android is awesome about making things easy!
- Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<WebView
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
Step 4:
Now navigate to our package and expand src -> my420time.Wob_Wrapper -> Main.java. Paste the code below into your Main.java file.
- Code:
package my420time.Wob_Wrapper;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Menu;
import android.view.MenuItem;
import android.view.Window;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class Main extends Activity {
/** Called when the activity is first created. */
//define our webview
WebView webview;
//define for menu option order
private static final int MENU_QUIT = 1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Remove the title bar with our application name.
requestWindowFeature(Window.FEATURE_NO_TITLE);
// Display our xml file we set up
setContentView(R.layout.main);
// Attach our defined webview to our layout
webview = (WebView)findViewById(R.id.webview);
// Turn java on for our newly created webview
webview.getSettings().setJavaScriptEnabled(true);
// Set where our webview will launch
webview.loadUrl("http://worldofbleach-rpg.com/");
// Watch if we are connected to the internet or not
// Not needed anymore on newer SDK
http://WebView.enablePlatformNotifications();
// Launch our application's webview
webview.setWebViewClient(new WoBClient());
}
/* Creates the menu items */
public boolean onCreateOptionsMenu(Menu menu) {
//Tells android what to show when we press the menu button.
menu.add(0, MENU_QUIT, 0, "Quit");
return true;
}
/* Handles item selections */
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case MENU_QUIT:
//Close down when pressed
finish();
return true;
}
return false;
}
@Override
//Capture when the phystical back key is hit
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()) {
webview.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
private class WoBClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
}
Step 5:
Navigate to AndroidManifest.xml and paste the code below to tell our application we need access to the internet!
- Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="my420time.Wob_Wrapper"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".Main"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-sdk android:minSdkVersion="3" />
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
Step 6:
Right click "WoB Wrapper" (The project) and click Run As -> Android Application. Congrats you've written your first android application! (You can also have it save a signed/unsigned apk for the market/your phone)

Ya, I don't plan to release my real version of the WoB app. ^_^ You'll have access to the source of course but won't be posted publicly. It is taking quite a bit of work to make it look nice and function like I want. This is just a very very basic http wrapper, which is the equivalent of opening the browser on your phone.

Re: Android: Your First App! WoB Wrapper
You should post a "Hello Android" tutorial though, that might be more helpful ^^ Although right now I'd just like to know how to do basic i/o. Nothing seems to be basic in Android though D:

Re: Android: Your First App! WoB Wrapper
Well, for basic I/O what exactly do you want to do? Have a settings file, read contacts, read/write files from the SDCard, and there are a few more gimme an idea. I'll write up a Hello world app as these are pretty generic in most languages. Then add functions to that in new replies on it.
