Presenting to Android phone from Eclipse

in Android Processing • 2 years ago

I am using Processing in Eclipse on a Mac and trying to find a quicker way to Present on an Android instead of copying, pasting, and editing my code in Processing and running it in Android mode there. I already added 
              
               
                public static void main(String args[]) { PApplet.main(new String[] { "--present", "ProgramName" }); }
              
 from http://processing.org/learning/eclipse/, but when I run as a Java Application with my phone connected, it doesn't run on the phone. Can someone help me solve this please? Thanks, Chloe

1) First of all, make sure you have installed the ADT plugin for Eclipse:

http://developer.android.com/sdk/eclipse-adt.html

2) Create a new Android project (File|New|Other...).

3) In the New Android Project window, select Android 2.1-update1 as the Build Target.

4) Then, you need to add Processing-Android core to the project. If you have used Processing 0191 in Android mode before, you should have a file named processing-android-core-0191.zip in your sketchbook folder. Change the extension to .jar and add it as a library (Project properties, Java Build Path|Libraries, Add External JARs).

5) Open the AndroidManifest.xml file and set the "Min SDK version" attribute in the "Uses Sdk" extra to 7.

6) The following code should serve as a skeleton for the project:

package processing.test;
import processing.core.*;
public class Test extends PApplet {
public void setup() {
}
public void draw() {
}
static public void main(String args[]) {
PApplet.main(new String[] { "Test" });
}
}

assuming you set Test as the Activity name and processing.test as the package name in step 3.

Thanks for your help! On step 5, my AndroidManifest.xml only shows the following. So where should I set the "Min SDK version" attribute in the "Uses Sdk" extra to 7?

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="hcii.chloefan"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
</application>
</manifest>

Also, when I try to run it as a Java application, the console says Terminated and there are no outputs. Am I supposed to export it as an Android application then load it on my phone?

Thanks a lot for your help :)

I was able to figure out step 5 and have it transfer to the Android device. It keeps force closing when I try to open it, though. when I migrate my code over. I think it's perhaps it doesn't know where to find the images I've loaded. I've tried placing them in the assets folder and accessing it from assets/image.png, etc, but that doesn't seem to work. Any ideas?

Thanks,

Chloe

Yes, the contents of data should go into the assets folder in the Eclipse project. Maybe there is another problem. You can check the error and printouts from your program using the LogCat window.
