emmitWithGravity error.

[Barterio]

Hi, i'm using Leonids to create background raining animation.
The problem is that all particles are running from the top left corner one by one. Can you help me handle it?

new ParticleSystem(MainActivity.this, 50, R.mipmap.ic_launcher, 5000)
                .setAcceleration(0.00013f, 90)
                .setSpeedByComponentsRange(0f, 0f, 0.05f, 0.1f)
                .setFadeOut(200, new AccelerateInterpolator())
                .emitWithGravity((Button)findViewById(R.id.mainForeground), Gravity.BOTTOM, 20);

The most likely problem is that you are starting the emitter inside onCreate or onStart.
At that moment, the views are not yet measured, therefore the system read the width of the view as 0.
You need to wait until the views are measured. Check out #22
