Error with VAO on Nexus 4 device only - opengl-es

Question

I've got a strange error on my nexus 4 with OpenGL ES2 when I use vertex array objects.
Here is some informations:
Everything work when I don't use VAO
Everything work on others device and on an Ipad 2 with and without VAO
glGetError() didn't return error
Due to the error some glitch appear in the game (some elements take another apparence)
My VBO are dynamics (I update them with glBufferData)
Here is the error:
Adreno-ES20(16818): : validate_vertex_attrib_state: No vertex attrib is enabled in a draw call!
And here is my code:
void Renderer::setVertexBuffer( Uint32 stream, const Base* vertexBuffer, std::size_t stride, Uint32 startVertex, Uint32 endVertex )
{
static const bool VAOSupported = this->isExtensionPresent(VertexArrayObject);
if( VAOSupported )
{
if( vertexBuffer->vao.isReady() == false )
{
// Bind VAO.
glBindVertexArrayOES( vertexBuffer->vao.getId() );
// Bind filled VBO.
glCheck( glBindBuffer( GL_ARRAY_BUFFER, vertexBuffer->getId() ) );
// Set attributs with vertex format.
this->applyVertexFormat( startVertex, endVertex );
// Unbind buffer and VAO.
glBindVertexArrayOES(0);
vertexBuffer->vao.isReady(true);
}
glBindVertexArrayOES( vertexBuffer->vao.getId() );
}
else
{
glBindVertexArrayOES(0);
glCheck( glBindBuffer( GL_ARRAY_BUFFER, vertexBuffer->getId() ) );
this->applyVertexFormat( startVertex, endVertex );
}
}
////////////////////////////////////////////////////////////
void Renderer::setIndexBuffer( const Buffer* indexBuffer, std::size_t stride )
{
glCheck( glBindBuffer( GL_ELEMENT_ARRAY_BUFFER, indexBuffer->getId() ) );
this->usedIndexBufferStride = stride;
}
////////////////////////////////////////////////////////////
void Renderer::applyVertexFormat( Uint32 startVertex, Uint32 endVertex )
{
const Uint32 stride = this->vertexFormat->getStride();
for( Uint32 i = 0; i < this->vertexFormat->getAttributCount(); i++ )
{
const VertexElement& element = this->vertexFormat->getAttribut(i);
glCheck( glEnableVertexAttribArray( element.usage ) );
glCheck( glVertexAttribPointer( element.usage,
element.type,
element.type,
element.normalize,
stride,
BUFFER_OFFSET(element.offset + startVertex * stride ) ) );
}
}
And here is how I use it :
renderer->setFormat(geometry->getFormat()); // Only save a pointer to the format to use in apply method.
renderer->setVertexBuffer(geometry->getVertexBuffer());
renderer->setIndexBuffer(geometry->getIndexBuffer());
renderer->draw(GL_TRIANGLES, geometry->indiceCount);

Answer 1

Are you sure usage is an appropriate name for the field that defines which attribute array to associate the pointer with? Buffer objects already have a property called usage (e.g. GL_DYNAMIC_DRAW). location might make more sense.
You have a much more serious issue in your code, however:
element.type cannot be both the type of your data and the number of components. glVertexAttribPointer (...) only accepts 1, 2, 3 or 4 components, an enumerant like GL_FLOAT has a value much larger than 4.
Assuming glCheck( ... ) correctly wraps glGetError (...), this situation should be indicating GL_INVALID_VALUE.
This leads me to believe that your loop in void Renderer::applyVertexFormat( Uint32 startVertex, Uint32 endVertex ) is never triggered.
