I suppose it is line 15, since you bolded it.
But what symbol cannot be found? Can you report the exact error message? I cannot test the code, not having an Android SDK installed.
I didn't even know PGL existed...

In the source code of PGL, I see this method called several times with GL.GL_TEXTURE_2D instead. Perhaps that's what to use...

thanks I'll check it !

I didn't even know PGL existed...

So am I The goal is to read textures compressed etc1 which are really efficient for loading and displaying fast ! the heap size is about 5 times less than png texture for instance !

Anybody would have kind of tips or advices about this this ?
thanks in advance.

Mmm, sorry, I was wrong, not sure why I mixed up things like that...

It is PGL.TEXTURE_2D (better use the class name, for static variables, instead of instances), which is just defined as GLES20.GL_TEXTURE_2D.

Now, the Processing name is bindTexture(), not glBindTexture(). The former calls the latter:

1.   public void bindTexture(int target, int id) {
2.     GL11.glBindTexture(target, id);
3.     if (target == TEXTURE_2D) {
4.       boundTextures[0] = id;
5.     } else if (target == TEXTURE_RECTANGLE) {
6.       boundTextures[1] = id;
7.     }
8.   }

So your call should look like:
pgl.bindTexture(PGL.TEXTURE_2D, 0);
Again, from what I see in the code...

thanks a lot ! no errors ! but still black screen- 
I guess I have to deal with texture buffers, vertices…
I'm really lost about the way to do this- It seems that opengl in processing has changed a lot since 1.5 !

Would some of you have a simple example of displaying a texture into a quad in low-level open gl ?  It would be a great point of start for me !
To be precise:
My goal is to load compressed texture ETC1- So I need to control the whole operation of loading textures to read etc1 and not jpeg…).
I'm on 2b08.
thanks in advance !

Here's the code I have so far :  Whatever I try for binding Textures, Activethem, make the application quits ! with nullpointer exception. It's pretty scary for me right now ! I'm afraid not to be able to do it…and it seems that few people have been working on the opengl code from P5…ouch…I'm scared…
here it is: any really really little tiny advices could give me hope again ;)
thanks in advance.

1. //try to get texture from texture compressed method in adroid (means binding textures in the sketch)
   
2. PGL pgl;
   int mTextureID;
   InputStream input;
   PShader pass;
   import java.nio.IntBuffer;
   import javax.microedition.khronos.opengles.GL10;
   import android.opengl.ETC1Util;
   import android.opengl.GLUtils;
   int[] textures = new int[1];
   
   int textureID;
   void setup()
   {
     size( 1280, 800, P3D);
     orientation(LANDSCAPE);
   //pgl.enable(pgl.TEXTURE_2D); //Everything I try make application quits with 'NullPointerException'
     //  pgl.activeTexture(pgl.TEXTURE0);
     //  pgl.bindTexture(PGL.TEXTURE_2D, textureID);
     println("ETC1 texture support: " + ETC1Util.isETC1Supported());//ETC1 COMPRESSION AVAILABLE ?
   }
   void mousePressed()
   {
     load();
   }
   void draw()
   {
     background(35, 200, 90);
     beginPGL();
   
     //  pgl.bindTexture(PGL.TEXTURE_2D, pgl.TEXTURE0);
     endPGL();
   }
   
   void load() {
   
   
     try {
   
       InputStream input = getApplicationContext().getAssets().open("texture.pkm");//you can download it here
       //
       //    pgl.texParameteri(PGL.TEXTURE_2D, pgl.TEXTURE_MIN_FILTER, pgl.NEAREST);
       //    pgl.texParameteri(PGL.TEXTURE_2D, pgl.TEXTURE_MIN_FILTER, pgl.LINEAR);
       ETC1Util.loadTexture(pgl.TEXTURE0, 0, 0,
       pgl.RGB, pgl.UNSIGNED_BYTE, input); //CLASS TO LOADTEXTURES FROM COMPRESSED PKM FILE
     }
     catch (IOException e) {
       println("Could not load texture: " + e);
     }
     finally {
       try {
         if (input != null)   input.close();
       }
       catch (IOException e) {
         // ignore exception thrown from close.
       }
     }
   }
   
   

I am also interested in that topic- but can't help you. maybe the settexture void could help ?
I don't know………
Maybe you should post in contributed library since OPENGL is involved ! Andres shouldn't be the only one to know about this  ;-)

ouch…nobody at all ? I'm in trouble and in rush… ! little tiny advices ? Sorry for posting so often, but I can't wait to have a little clue

i had a similar (i think) problem last night, textures not displaying in opengl (was trying to convert processor heavy code to use opengl display lists. it helped, but not enough).

anyway, i found this thread on the old forum

http://processing.org/discourse/beta/num_1199399046.html

specifically the bit that said to use

// necessary import
import import com.sun.opengl.util.texture.*; 
...
// define texture
Texture tex;
...
// setup
  // load texture (png and jpg both work, maybe more)
   try { tex=TextureIO.newTexture(new File(dataPath("test.png")),true); }
   catch(Exception e) { println(e); }
...

// when drawing
// enable and use texture
tex.enable();
tex.bind();
...
// disable
tex.disable();

thanks Koogy !!
Unfortunately I have to understand how to do it without other libs than opengl (my goal is to adapt this to android with opengl2ES, opengl10, lib.)

All I would have to understand is what's going on inside when I invoke texture(PImage). It would be a really good start of point ! how the texture is generated…
(gl.glTexImage2D, glbindtexture, glenabletexture…)

Unfortunately, the low-level opengl from the examples don't dealt with textures…

I'm stuck at g.texture ! (when the void texture() is invoked, it seems to run g.texture according to sources…
But I really don't know what it stands for.
