J2me run an android using Netbeans IDE

If you want  J2ME code was run an android  just follow the steps

Step 1:

First Create Android Application (  Netbeans Configure with Android  )

Step 2:

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

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

     package="org.me.list">

    <application>

         <activity android:name=".SearchListActivity" android:label="SearchListActivity">

            <intent-filter>

                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>

            </intent-filter>

        </activity>

    </application>

</manifest>

 

To be able to use the vibrator you have to add the following tag to your

            AndroidManifest.xml file:

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

            In some special cases, you may want to bypass restarting of your activity

            based on one or more types of configuration changes. This is done with

             the android:configChanges attribute in its manifest. For any types of

               configuration changes you say that you handle there, you will receive a

               call to your current activity's onConfigurationChanged(Configuration)

              method instead of being restarted. If a configuration change involves any

              that you do not handle, however, the activity will still be restarted and

               onConfigurationChanged(Configuration) will not be called."          

               interesting info on 'sensor' orientation detection (or the lack of ..)

             http://androidguys.com/?p=2914

              

              I strongly suggest using the following attribute within the <activity/> tag in the

              AndroidManifext.xml file:

             

              android:configChanges="keyboardHidden|orientation"

                // http://android-developers.blogspot.com/2009/04/updating-applications-for-on-screen.html

     The virtual keyboard behavior can be configured from the AndroidManifest.xml file.  For example:

     <activity name="myactivity"

        android:windowSoftInputMode="adjustResize">

        ...

    </activity>

    This will shrink the LWUIT form once the keyboard appears.  By default the keyboard will be shown on top

    it seems.

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

<manifest xmlns:android="http://schemas.android.com/apk/res/android"  android:versionCode="1"

          android:versionName="1.0.0"

               package="org.me.list">

    <application>

        <activity android:name=".SearchListActivity " android:screenOrientation="sensor" android:configChanges="keyboardHidden|orientation" android:windowSoftInputMode="stateVisible|adjustResize"  android:label="SearchListActivity ">

            <intent-filter>

                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>

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

            </intent-filter>

        </activity>

    </application>

</manifest>

Step 3:

Create Assets( we wanted to add some resources in the assets directory for use an Android Application if you not create assets raise File not found exception)

1. Create a directory called ‘assets’ at your project root (same dir that AndroidManifest.xml lives)
2. In /nbproject/project.properties, change

assets.dir=

to

 assets.dir=assets

assets.available=true

asset.dir=assets

3. In /nbproject/build-impl.xml, there is line in the “if=assets.available” target that reads

4.      <arg value="${asset.dir}"/>

that needs to be changed to

<arg value="${assets.dir}"/>

That’s it – you should be all set and “file:///android_asset/” should be accessible to your application and contain the contents of your project’s assets directory.

Step 4:

1.Download Code from  following Link4Source copy  that files and load to the Src directory

2.Find Src\org\meteoroid\test\ and load ur J2ME MIDlet File and supported Files

Chage ActivityName,Package name in AndroidManifest.xml

3.Set MIDlet File location on assets\META-INF\MANIFEST-MF change

MIDlet-1: MIDlet_Title,/icon.png,org.App.test.MainMidlet

MIDlet-2: Canvas,/icon.png,org.App.test.TestMIDlet2

.

.

.

4.Load image,Txt,and other resources to load in Assets

Step 5:

Build Android Appliaction,then Run the Appliaction

Lwuit with android using Netbeans IDE:

If you want  LWUIT code was run an android  just follow the steps

Step 1:

First Create Android Application (  Netbeans Configure with Android  )

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

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

                <category android:name="android.intent.category.LAUNCHER"/>

            </intent-filter>

        </activity>

    </application>

</manifest>

Step 2:

Just Change your android Appliction project AndroidManifest.xml for supporting  Android Devices      

To be able to use the vibrator you have to add the following tag to your

            AndroidManifest.xml file:

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

        In some special cases, you may want to bypass restarting of your activity

        based on one or more types of configuration changes. This is done with

        the android:configChanges attribute in its manifest. For any types of

        configuration changes you say that you handle there, you will receive a

        call to your current activity's onConfigurationChanged(Configuration)

        method instead of being restarted. If a configuration change involves any

        that you do not handle, however, the activity will still be restarted and

        onConfigurationChanged(Configuration) will not be called."        

         interesting info on 'sensor' orientation detection (or the lack of ..)

    This will shrink the LWUIT form once the keyboard appears.  By default the keyboard will be shown on top it seems.

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

            <intent-filter>

                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>

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

            </intent-filter>

        </activity>

    </application>

</manifest>

Step 3:

Create Assets( we wanted to add some resources in the assets directory for use an Android Application if you not create assets raise File not found exception)

1. Create a directory called ‘assets’ at your project root (same dir that AndroidManifest.xml lives)
2. In /nbproject/project.properties, change

to

 assets.dir=assets

assets.available=true

asset.dir=assets

3. In /nbproject/build-impl.xml, there is line in the “if=assets.available” target that reads

or Line 427,443

<arg value="${asset.dir}"/>

that needs to be changed to

<arg value="${assets.dir}"/>

That’s it – you should be all set and “file:///android_asset/” should be accessible to your application and contain the contents of your project’s assets directory.

Step 4:

1. Fetch LWUIT code from SVN link is: https://svn.java.net/svn/lwuit~svn/trunk
2. Remove LWUIT classes that use APIs unsupported on Android:

6. Remove the com.sun.lwuit.impl.midp package.
7. Remove all 3D stuff (M3G and Transition3d)
8. Remove SVGImage class.
9. Remove the com.sun.lwuit.util.Log class.
10. Remove the com.sun.lwuit.impl.ImplementationFactory class (use the one from this repository).
11. Add LWUIT with Android supported Classes 

Extend the com.sun.lwuit.impl.android.LWUITActivity class and implement the abstract method that returns the path to your MIDlet class.  sample:

MyActivity.java

                public class MyActivity extends LWUITActivity{

                    public String getFullApplicationPath(){

                        return "com.demo.Sample.MainMIDlet";

                        // (make sure that obfuscators don't mess with the class name and path.)

                    }

                }

MainMIDlet.java

package com.demo.Sample;

import com.sun.lwuit.Display;

import javax.microedition.midlet.MIDlet;

import javax.microedition.midlet.MIDletStateChangeException;

/**

 *

 */

public class MainMIDlet extends MIDlet  implements BaseClass {

    private MainMIDlet midlet = null;

    public MainMIDlet() {

    }

    @Override

    protected void startApp() throws MIDletStateChangeException {

        if(midlet == null){

            midlet = this;

            Display.init(midlet);

            new MyApp(midlet).startMyApp();

        }

    }

    @Override

    protected void pauseApp() {

    }

    @Override

    protected void destroyApp(boolean arg0) throws MIDletStateChangeException {

        this.exitMyApplication();

    }

    public void exitMyApplication() {

        this.notifyDestroyed();

    }

}

BaseClass.java

package com.demo.Sample;

/**

 * implement platform dependent methods.

 */

public interface BaseClass {

    public void exitMyApplication();

}

MyApp.java

/*

public class MyApp {

    private final BaseClass baseClass;

    public MyApp(BaseClass baseClass){

        this.baseClass = baseClass;

    }

    public void startMyApp() {

        try {

            Resources r = Resources.open("/androidTheme.res");

            UIManager.getInstance().setThemeProps(r.getTheme(r.getThemeResourceNames()[0]));

            if(Display.getInstance().isTouchScreenDevice()){

                UIManager.getInstance().getLookAndFeel().setTouchMenus(true);

                UIManager.getInstance().getLookAndFeel().setTactileTouchDuration(50);

                Font font = Font.getDefaultFont();

                final int height = font.getHeight()/2;

                Style buttonStyle = UIManager.getInstance().getComponentStyle("SoftButton");

                buttonStyle.setPadding(height, height, buttonStyle.getPadding(Component.LEFT), buttonStyle.getPadding(Component.RIGHT));

                UIManager.getInstance().setComponentStyle("SoftButton", buttonStyle);

            }

            final Form demoForm = new Form();

            demoForm.setScrollable(false);

            demoForm.setLayout(new BorderLayout());

            demoForm.addCommand(new Command("Exit") {

                public void actionPerformed(ActionEvent evt) {

                    baseClass.exitMyApplication();

                }

            });

            demoForm.setTactileTouch(false);

            demoForm.addComponent(BorderLayout.CENTER, new Label("We got it"));

            demoForm.show();

        } catch (IOException ex) {

            ex.printStackTrace();

            baseClass.exitMyApplication();

        }

    }

}

4.Load image,Txt,and other resources to load in Assets

Step 5:

Build Android Appliaction,then Run the Appliaction

Sample Project Link

Note:

While when run android application run on Netbeans IDE before start Android SDK Virtual Devices

  Android Configure with NetBeans : (http://wiki.netbeans.org/IntroAndroidDevNetBeans)

Step 1:

Netbeans ==>MeunBar==>Tools==>Plugins==>Settings(Tab)==>Click Add Button

 

2.Update Center Customizer

Name : nbandroid or any name…

URL : :http://kenai.com/downloads/nbandroid/updates.xml

3.Another Alternative Method for to add android Plugin .Just Download latest AndroidPlugin(.nbm files) from  http://kenai.com/projects/nbandroid/downloads

1.Tools==>Plugins==>Downloaded(Tab)==>Add plugins==>Browse The latest Android Plugin(.nbm files)==>Install

Step 2:

1. Plugins==>Available Plugins(Tab)==>type Android in Search Box
2. Then Click Android CheckBox ==>Install

 

 

Step 3:  

Netbeans==>File==>Open Project

Step 4:

1.Enter Project Name, Set Package Name

2.Android Platform hasn’t been Specified, So first set Android SDK Platform.

3.Click Mange Platform or ToolsèJava Platform

4.JavaPlatform Addplatform  

5.Select Google Android Handheld Platform

6.Browse Android SDK Loaction(E.g: D:\Software\Android\Android_SDK_2_2\Android SDK)

 7.Final Set Android Platform Name: Android or any Name….

8.If  you like add no of android platform on different names.

Step 5:

Sample Project List Download Link

New Project Structure Flow:

The file SearchListActivity.java is as shown below:

/*

 * To change this template, choose Tools | Templates

 * and open the template in the editor.

 */

package org.me.list;

import android.app.Activity;

import android.os.Bundle;

/**

 *

 * @author Surendran

 */

public class SearchListActivity extends Activity {

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle icicle) {

        super.onCreate(icicle);

        // ToDo add your GUI initialization code here  

       

    }

}

 An Android application is organized as a set of activities. The file SearchListActivity.java that has been generated is the searchlist activity class for this application.

---

Whenever run your android Appliction in Netbeans before just create  the  preferred AVD

Then run your application otherwise at the runtime you got server not found error

1.Select Android SDK Manager Loacation

2.Select Virtual Devices then create New Android Virtual Device

1. Select whatever platform level you need maximum select low level because your App’s  run on old android devices

2. Click Start for launch  Android Virtual device

Running your project

Now, build and Run your project as you would do with any other NetBeans project. Your project builds successfully and the Android emulator boots up: 

Where is our Hello World?

Just add

setContentView(R.layout.main);

to the above file in place of

// ToDo add your GUI initialization code here

This should have been generated by the plugin, because the main.xml containing the main view was generated.

Alternatively we can do the following.

We shall now add support to the skeleton code to display the text- Hello, Android. Add the following to the above file in place of the "// ToDo add your GUI initialization code here":

TextView tv = new TextView(this);

tv.setText("Hello, Android");

setContentView(tv);

You will notice that the IDE complains- "Cannot find symbol". This is because we need to import the class TextView. Its easy with NetBeans. Just click on the yellow bulb and select "Add import for.."

The file should now look like:

/*

 * To change this template, choose Tools | Templates

 * and open the template in the editor.

 */

package org.me.list;

import android.app.Activity;

import android.os.Bundle;

import android.widget.TextView;

 /**

 *

 * @author Surendran

 */

public class SearchListActivity extends Activity {

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle icicle) {

        super.onCreate(icicle);

       

       TextView tv = new TextView(this);

       tv.setText("Hello, Android");

       setContentView(tv);

//setContentView(R.layout.main);

//output:Hello Android from Netbeans

    }

}

Now, run the project again

Prevent Selection of Target on Each Run 

When you run your project you are given a dialog asking which android device or emulator you would like to use. This can get annoying after several compile/run iterations. To set a default target, right click on the project name, select Properties. Select Run. Click on Automatic and set the preferred AVD. If you do not set the preferred AVD, NetBeans will continue to ask you at each run instance.
