This is related to "Uninstall old Android SDK versions", except I'd want to do it on a headless Linux CI server (short on disk space).
Does the android command line tool provide options for removing older parts of the SDK? With a quick look, the only things it can delete are AVDs. Did I overlook something?
Alternatively, I guess I could just manually delete stuff from under SDK_HOME. But what things are safe to delete? Other candidates than these?
- I only need to support API level 14 and up, so I suppose I can delete
stuff under
platforms/likeandroid-3andandroid-4. docs(800MB),samples(300MB)- How about
system-images? Do I need e.g.android-18/armeabi-v7a/andandroid-18/x86/if I only want to do automated APK builds (no emulator stuff) using Gradle (and Ant)?
At least upon deleting docs completely, the next time I ran android update sdk --no-ui, it started fetching them again:
Downloading Documentation for Android SDK, API 19, revision 1
Can I avoid update adding back parts of the SDK that I threw away?
Disclaimer: yes, disk is cheap and really I should just add more. But right now on this particular server (8.5G disk) I don't have that option, yet I'd still like to get it to run Android 19 builds...
Anything except tools/ can be re-installed generally with an
android list sdk -a
and
android update sdk --no-ui -a --filter <#index>
I will often blow away my add-ons/ and build-tools/ folders and reinstall my add-ons/ and build-tools/. If you need to automate accepting the license, another little trick is the following, at least if you're installing them one at a time:
android update sdk --no-ui -a --filter <#index> 0<<EOF
y
EOF
The "android" command itself lives within the "SDK Tools" package or tools/ directory, so you can't remove that, because then you can't install anything else. I also generally wouldn't remove platform-tools/, as then you can't build anything, unless you're installing a new/older version. If you look under <sdk-folder>/SDK Readme.txt, you will see the following in the first paragraph to confirm this:
Welcome to the Android SDK!
The Android SDK archive initially contains only the basic SDK tools. It does not contain an Android platform or any third-party libraries. In fact, it doesn't even have all the tools you need to develop an application.
In order to start developing applications, you must install the Platform-tools and at least one version of the Android platform, using the SDK Manager.
It seems that you need to download just the parts that you need. Doing a android update sdk --no-ui without other parameters downloads everything, and thus is time-consuming and wasteful.
The --filter parameter to determine the packages that you need, and using them each time you want to do an update. There's a more detailed explanation on how to do that here (and even more on the android command here).
If periodically changing the components that are needed (e.g. targeting a different platform), you could create a script that deletes the components under the various folders that are not needed (e.g. APIs under android-sdk-linux/platforms) and then re-create with just the components that you want.
The android list sdk -e command will give an extended list of packages that can be used with the --filter parameter, and thus allows installation of just specific components.
After reviewing an excellent answer automated way to use the expect command to automatically accept the license prompts, I ended up with this to install and update the components that I need, without downloading everything else (on Ubuntu):
expect -c '
set timeout -1;
spawn /opt/android-sdk-linux/tools/android update sdk --no-ui --filter tools,build-tools-20.0.0,platform-tools,android-16,extra-android-support,extra-android-m2repository;
expect {
"Do you accept the license" { exp_send "y\r" ; exp_continue }
eof
}
'
Note the components tools,build-tools-20.0.0,platform-tools,android-16,extra-android-support,extra-android-m2repository specified with the --filter parameter that restrict the download to just these parts.
Running this script once downloads just those components. Running again determines that nothing needs updating, but does give a confusing set of messages:
Error: Ignoring unknown package filter 'tools'
Error: Ignoring unknown package filter 'build-tools-20.0.0'
Error: Ignoring unknown package filter 'platform-tools'
Error: Ignoring unknown package filter 'android-16'
Error: Ignoring unknown package filter 'extra-android-support'
Error: Ignoring unknown package filter 'extra-android-m2repository'
Warning: The package filter removed all packages. There is nothing to install.
Please consider trying to update again without a package filter.
These messages just mean that nothing was updated -- components included in the --filter specification aren't actually uninstalled.
From what I've been able to gather, you can just delete directories in /platforms /skins and /system-images
