Android locator 7x30 waters

 

Could you list all possible directories where Android apps may store data, providing description what kind of data are stored in each directory?

All apps (root or not) have a default data directory, which is /data/data/<package_name> . By default, the apps databases, settings, and all other data go here. If an app expects huge amounts of data to be stored, or for other reasons wants to "be nice to internal storage", there's a corresponding directory on the SDCard ( Android/data/<package_name> ).

Apart from that, all apps can store data anywhere on the SDCard, as there are no restrictions -- and many apps do so. They can use directory names freely (and they again do), which is what often makes it hard to decide what all that "junk" on the card is intended for, and what of it can be deleted.

Android locator 7x30 waters

I have installed a few Android applications both with the adb install MyApplication.apk command and via a webserver (like an alternative to Android Market).

But where in the Android file system on my phone is the MyApplication.apk file placed? Are applications installed with adb install not placed in the same directory as applications downloaded from the Market?

I found some applications on /system/app but I can't recognize them as some downloaded from Android Market or the one I have installed with adb install .

public class Location
extends Object implements Parcelable

A data class representing a geographic location. A location can consist of a latitude, longitude, timestamp, and other information such as bearing, altitude and velocity. All locations generated by the LocationManager are guaranteed to have a valid latitude, longitude, and timestamp (both UTC time and elapsed real-time since boot), all other parameters are optional.

Constant used to specify formatting of a latitude or longitude in the form "[+-]DDD:MM.MMMMM" where D indicates degrees and M indicates minutes of arc (1 minute = 1/60th of a degree).
