Android locator x92.9

 

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.

I have Xamarin Studio, and I need to specify the Android SDK Location. I have previously had Xamarin Studio working on my pc, and for some reason, I need to enter this again.

Have you tried to find this folder via the Windows explorer? Can it been seen? Maybe the folder is hidden (by default install - it is hidden by the Windows operating system in the users folder). Just check that you can view hidden folders in Windows explorer (by the settings in the windows control panel > appearance and personalization > folder options > show hidden files and folders.

This happened to me as the Windows OS could not find the SDK folder which was required for the Android Studio SDK path, and was resolved by showing hidden files and folders, which enabled me to complete the default SDK install path location.

Knowing a user’s location in an Android app can be extremely useful. Users take their devices everywhere and are constantly using them on the go, and as developers we can capitalize on that by providing a more contextual experience based on their current location.

Accessing the current location of an Android device is easier than ever, but it can still be a little tricky, especially for the first time. What follows is a guide on the very basics of retrieving a user’s current location and displaying it with a marker on a map. The project files for this project are available on GitHub , but follow along and in a few minutes we’ll build a super simple location finder!

This is a somewhat complex topic in Android, but these step-by-step guidelines should explain everything you need. If you would like to learn more about the fundamentals of Android programming that lead up to this, please check out my Android Development Track on Treehouse.
