How can I get the external application data path in android?

Question

I would like to store some cache data in the path /sdcard/Android/data/, but how can I get it?

Answer 1

simply use Context.getExternalCacheDir(), this is the standard way android provides for external cache, when your app uninstalled, the dir removed automatically and don' t leave any trash for the user.

the dir pattern ends like Android/data/your-package-name/cache/

but you should check null for the return value (a File object), if null, it indicates that the cache dir is not avaialbe(like sd card removed or connected to your pc, etc.)

Answer 2

I am doing this before saving my files to my external folder.

String pathToExternalStorage = Environment.getExternalStorageDirectory().toString();
File appDirectory = new File(pathToExternalStorage + "/" + getText(R.string.app_name));

if (!appDirectory.isDirectory() || !appDirectory.exists()) //Checks if the directory exists
    appDirectory.mkdir();
