Why is it that some bash programs will only run on my system when I type ./ before their name?
An example: In my [...]/android/sdk folders I have to execute adb like this:
./adb devices
Why not just adb devices?

What is missing from many answers is that this is a relative path made out of a reference the current directory file (.) and the rest of the path from that point, in the context of pathname resolution.user44370– user443702014-07-02 01:36:38 +00:00Commented Jul 2, 2014 at 1:36

If you run
echo $PATH
you will see a list of directories that your system will search for commands to run.
If you want to run commands in your current working directory, then you can run:
PATH=$PATH:.;export PATH
You can add this line to your ~/.bash_profile to have this behaviour persistent across sessions.
. is the symbol for your current directory. You have to include the / so it knows that it's not a . at the beginning of the file. If you navigate to a different directory and type the directory of the file, you don't have to have the ./
