I've found this answer How to get a list of installed android applications and pick one to run

But it doesn't answer my problem completely, although I only have to find if a specific application is installed, I have no context in the library, so i can call getPackageManager() and get the list of applications.

Are there any other way to do it? Maybe a Java only solution by searching in the Android file system?

Please help!

You will generally have to add Context parameter to your library API, to init function for example, and pass a Context from the application that uses it.

However, there is a hackish workaround (single-line, to highlight that it's an ugly hack):

if (Runtime.getRuntime().exec(new String[]{"/system/bin/sh","-c","cd /data/data/jackpal.androidterm"}).waitFor() == 0) { Log.d("!!!", "Android Terminal Emulator app is installed"); }

This code will check if the private app directory exists in Andorid filesystem. You cannot list private directory of another app, or open any files from it, however you can check if the directory itself exists just by trying to chdir there.
