I am trying to run the command in ubuntu
android update project --path .
However I am getting a android:command not found error.
I assume this is something to do with the path which I learnt on here the other day? I was just wondering, what do variable do I need to add (Android I assume) and what do I need to point it too.
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.
Another possibility is simply that your "android" file is not executable. Navigate to the tools path in terminal and then make it executable by:
chmod 777 android
Then you can run:
./android sdk
It's what worked for me.
Assuming that you have set ANDROID_HOME to point to the sdk install, you should add $ANDROID_HOME/tools and $ANDROID_HOME/platform-tools to your PATH.
Sometimes even after you add your android_sdk/ dir path from command line it still doesn't work and gives the command not found error, in that case follow these steps. I ran through this issue myself and i tried all the above steps and none worked so i thought i should share and perhaps that might help somebody.
( android-sdk-linux is the name of android sdk library which you have extracted ).
1) Open the bashrc file from command line
gedit ~/.bashrc
2) Add following lines at the top.
export PATH=${PATH}:~/android-sdk-linux/tools
export PATH=${PATH}:~/android-sdk-linux/platform-tools
3) Log out of the system and log back in. Type Ctrl + Alt + T to open command line and type android to launch the software.
After installing Android studio. Create or edit your ~/.bashrc file and add the following lines:
export ANDROID_HOME=~/Android/Sdk
export PATH=${PATH}:${ANDROID_HOME}/tools
and reload .bashrc
source ~/.bashrc
That's because your platforms and platform-tools are not in the PATH environment variable. You can run the adb command with path-to-adb/adb or add platforms and platform-tools to PATH and run typing only adb
This is my path environment variable:
PATH=/usr/local/bin:/usr/bin:/bin:/opt/bin:/usr/x86_64-pc-linux-gnu/gcc-bin/4.5.3:/opt/android-sdk-update-manager/tools:/opt/android-sdk-update-manager/platform-tools
For Mac, go into your home directory by typing cd ~, and then type vi .bash_profile, This file might be empty or just created, and this is not a problem.
To edit the file, press i on your keyboard and inside the file, type the following path:
export PATH="/Users/YOUR-USERNAME-HERE/Library/Android/sdk/platform-tools":$PATH
export PATH="/Users/YOUR-USERNAME-HERE/Library/Android/sdk/tools":$PATH
When you are done, press esc, and again press shift : and type wq. Okay, now you saved your file. Now, quit terminal and re-launch, and try typing:
adb -h
android -h
If both commands are giving you output, it means everything works fine.
Not: We used vi command to edit the file. If you got confused with this command, you can also try nano for editing the file.
android is now inside android-sdks/tools
if you are using mac, you may set your .bash_profile to include it.
PATH=$PATH:[android-sdks]/platform-tools:[android-sdks]/tools
Uninstall cask android-platform-tools
brew cask uninstall android-platform-toolsInstall it using Android Studio
