Out of memory exception with using multiple high resolution textures

[ParagRKadam]

This is the error that I am getting when I use multiple(~30 images) high resolution(4096 X 2048) textures with each image being around 5 MB on Nexus 5 android version 4.4.4.
E/Adreno-GSL﹕ <ioctl_kgsl_sharedmem_alloc:1532>: ioctl_kgsl_sharedmem_alloc: FATAL ERROR : (null)

I have several Images stored in my android app locally in the drawable-nodpi folder. And I change the texture of my sphere very often by calling the following function in VR app:-

public void changeImage(int imageResourceId) {

    Texture t = new Texture("sphereTexture", imageResourceId);
    t.shouldRecycle(true);
    ArrayList<Object3D> objectList = getCurrentScene().getChildrenCopy(); // Get reference to sphere

    Material material = objectList.get(0).getMaterial(); // get material of sphere
    for (ATexture texture : material.getTextureList()) {// remove previous texture on material
        material.removeTexture(texture);
        texture = null;
    }


    try {
        material.addTexture(t); // add new texture to material
    } catch (Exception e) {
        e.printStackTrace();
    }
}

So my question is, is it possible to get rid of this error? Is there any recommendation for using image textures like what is the right resolution for image textures etc.
