This library suffers from some fundamental problems. New projects should look elsewhere, and existing projects should plan on migrating to something else. This library is discontinued and deprecated.

Options include:

• Various other open source camera libraries for Android
• CWAC-Cam2, the author's second attempt at a camera library
• using the Android SDK APIs (Camera and android.hardware.camera2.*) directly
