There is a strange problem for me after i installed the android environment and put the paths like here in this question link
I write the command:
$ and
After adding the PATH entry to your ~/.profile file as mentioned above, log out and back in. That way your entire session will have android in the path.
I would also add platform-tools to your PATH as well. That give you adb.
So, add something like this to your ~/.profile:
export PATH=$PATH:path_to_sdk/tools:path_to_sdk/platform-tools
Where you replace "path_to_sdk" in the example with the directory were you extracted the Android SDK (e.g. /usr/local/android-sdk-linux).
