I got the following error while using the particle emitted with the following settings:

                if (mParticleSystem == null) {
                    mParticleSystem = new ParticleSystem(getActivity(), 100 /* maxParticles */,
                            R.drawable.particle_white_bubble, 3000L /* timeToLive */);
                    mParticleSystem.emit(emitLeft ? 0 : mScreenSize.x, mScreenSize.y / 2,
                            12 /* particlesPerSecond */);
                } else {
                    mParticleSystem.updateEmitPoint(emitLeft ? 0 : mScreenSize.x,
                            mScreenSize.y / 2);
                }
                mParticleSystem.setSpeedModuleAndAngleRange(0f, 0.1f,
                        emitLeft ? 315 : 90, emitLeft ? 90 : 225)
                        .setScaleRange(0.9f, 1.1f)
                        .addModifier(new ScaleModifier(0f, 1f, 0L, 3000L))
                        .setFadeOut(3000L);
