I am trying to run the command in ubuntu
android update project --path .
However I am getting a android:command not found
On MacOS/Linux, define the path to wherever you installed your SDK as ANDROID_HOME:
MacOS
$ export ANDROID_HOME=/Applications/android-sdk-macosx
If you installed Android Studio, the value will need to be
export ANDROID_HOME=$HOME/Library/Android/sdk
Linux
$ export ANDROID_HOME=~/android-sdk-linux
Then add the paths to the platform-tools and tools sub-directories (Same on MacOS/Linux).
export PATH=$ANDROID_HOME/tools:$PATH
export PATH=$ANDROID_HOME/platform-tools:$PATH
You should now be able to run android from the shell.
If none of the suggested ANDROID_HOME paths above are valid, you can find the (uniquely and consistently named) platform-tools folder via:
find / -name platform-tools 2>/dev/null
Whatever path that returns will need to be trimmed down to end with either sdk, android-sdk-linux, or android-sdk-macosx.
Assuming that you have set ANDROID_HOME to point to the sdk install, you should add $ANDROID_HOME/tools and $ANDROID_HOME/platform-tools to your PATH.
For Mac, go into your home directory by typing cd ~, and then type vi .bash_profile, This file might be empty or just created, and this is not a problem.
To edit the file, press i on your keyboard and inside the file, type the following path:
export PATH="/Users/YOUR-USERNAME-HERE/Library/Android/sdk/platform-tools":$PATH
export PATH="/Users/YOUR-USERNAME-HERE/Library/Android/sdk/tools":$PATH
When you are done, press esc, and again press shift : and type wq. Okay, now you saved your file. Now, quit terminal and re-launch, and try typing:
adb -h
android -h
If both commands are giving you output, it means everything works fine.
Not: We used vi command to edit the file. If you got confused with this command, you can also try nano for editing the file.
