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
