    <p>I have a GLSurfaceView where I render my scene. My scene display correctly except for some textures where I have white squares instead of the real texture. I use 2 types of texture :</p> <ul> <li>Some textures are in the resources of the project. I create them in <code>onSurfaceCreated</code>, everything works fine with them</li> <li>Some other needs to be downloaded from a remote location. Those are the textures that don't display correctly.</li> </ul> <p>I download and create the "lazy texture" with the following code :</p> <pre><code>public void onDrawFrame(GL10 gl) { ... Texture3D.getDynamicTexture(gl, object.avatar).bind(gl); ... } public static Texture3D getDynamicTexture(GL10 gl, int key) { Texture3D texture = dynamicTextures.get(key); if (texture == null) { dynamicTextures.put(key, new Texture3D(gl, key, Type.DYNAMIC)); texture = getStaticTexture(R.drawable.broken_img); } return texture; } public Texture3D(final GL10 gl, final int id, Type type) { gl.glEnable(GL10.GL_TEXTURE_2D); gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_NICEST); texture = newTextureID(gl); gl.glBindTexture(GL10.GL_TEXTURE_2D, texture); gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR); gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); Utils.loadImage(id, new SimpleImageLoadingListener() { @Override public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) { _pBitmap = loadedImage; GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, _pBitmap, 0); _pBitmap = null; gl.glEnable(GL10.GL_BLEND); } }); </code></pre> <p>I see that the download works because R.drawable.broken_img got replaced by a white square. The textures seems to appears but they are all stacked on top of the screen on a single line (see the picture).</p> <p><img src="https://i.stack.imgur.com/PcMnt.png" alt="Stacked textures on top of the screen"></p> <p>I also tried <a href="https://stackoverflow.com/questions/5691365/android-opengl-es-1-1-white-box-textures?rq=1#comment7340488_5692352">Android OpenGL ES 1.1 white box textures</a> but that didn't work either. The only difference I saw was that the textures didn't appear anymore on top of the screen.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
