getting nullpointer exception. Does not get any idea to solve it.

@Override protected void preDraw(final GLState pGLState, final Camera pCamera) { super.preDraw(pGLState, pCamera); //////********** getting error here***********////// this.getTextureRegion().getTexture().bind(pGLState); try { }catch (Exception e){} this.mSpriteVertexBufferObject.bind(pGLState, this.mShaderProgram); } — Malashree Halade, Aug 22 '19 at 06:07

Look in org.andengine.entity.sprite.Sprite.java on line 243. There is a reference to an org.andengine.opengl.texture.ITexture org.andengine.opengl.texture.region.ITextureRegion in there which is null... meaning it has not been initialised.

Without seeing the actual code, it is impossible to provide an explanation as to why the ITextureRegion is uninitialised.

For you to understand this better, I recommend reading What is a NullPointerException, and how do I fix it?

this.getTextureRegion().getTexture().bind(pGLState); at this getting null pointer – Malashree Halade Aug 22 '19 at 06:41
Yes. So the value returned by `this.getTextureRegion()` is null. Determining the reason is impossible without having access to the code. – Captain Aug 22 '19 at 06:43
