The Environment.DIRECTORY_PICTURES variable stores the path to image directory in Android 2.2 (API 8).
What is the most reasonable way to acquire this path in pre-8 versions?
It’s probably (is it always in pre-8?) equivalent to the sdcard mountpoint.
The true answer: You can not know for certain.
The most probable answer:
Environment.getExternalStorageDirectory().getAbsolutePath() + "/DCIM"If you know the last picture added to the device was from the camera, you can use the solution here: get current picture folder of camera
