How do I take very long exposure photos?

Question

I would like to take some long exposure photos using my Android phone (Moto DROID v1 running Android 2.2.2) of the night sky. I experimented with the settings for the default camera app, and I found that I can set the focus to infinity, but the exposure time has only three settings: 0, +1, and +2. If I set the exposure to +2, I can get a recognizable photo of a full moon, but I am unable to capture a field of stars.

Is there any way to extend the exposure time beyond +2?

Note: there's a misunderstanding between exposure compensation and shutter speed. The exposure setting on the camera app is the first one, not about the duration of the exposure. — Andrew T., Oct 23 '15 at 15:02

You cannot do this from with Settings of the default camera.

You could look at another camera app like Camera Streak (Blog).

Or you could roll your own, here is the relevant details you need to change:

I tried camera streak, but without tight control over ISO I just wound up with either a black image or a bright, fuzzy blob. – JadeMason Oct 07 '11 at 16:04

You could try Camera FV-5. It only lets you go up to 1 minute exposure, but it has ISO control, and the Lite version isn't restricted or watermarked.

You can use Long Exposure Camera 2. This app can be used to achieve very long shutter exposure.
