Textured problem

hello, changed  3D image the imagentarget with another image and I have an error with texture no coupled with the image

Here is the modified code

Change code ImageTargetRenderer VuforiaSamples

declared

private Mammut mMammuth;

private float kBuildingScale = 200.0f;

in initRendering()

mMammuth = new Mammut(mActivity.getResources().getAssets());

in renderFrame() change mTeapot

GLES20.glDisable(GLES20.GL_CULL_FACE);

GLES20.glVertexAttribPointer(vertexHandle, 3, GLES20.GL_FLOAT, false, 0, mMammuth.getVertices());

GLES20.glVertexAttribPointer(textureCoordHandle, 2, GLES20.GL_FLOAT, false, 0, mMammuth.getTexCoords());

GLES20.glEnableVertexAttribArray(vertexHandle);

GLES20.glEnableVertexAttribArray(textureCoordHandle);

GLES20.glActiveTexture(GLES20.GL_TEXTURE0);

GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, mTextures.get(0).mTextureID[0]);

GLES20.glUniformMatrix4fv(mvpMatrixHandle, 1, false, modelViewProjection, 0);

GLES20.glUniform1i(texSampler2DHandle, 0);

GLES20.glDrawArrays(GLES20.GL_TRIANGLES, 0, mMammuth.getNumObjectVertex());

excuse my writing, I do not know English
