Error in updating to ADT rev 23 for Eclipse [duplicate]

Question

I updated Eclipse with the new SDK tools (rev. 23), but now when Eclipse starts I receive the error:

This Android SDK requires Android Developer Toolkit version 23.0.0 or above. Current version is 22.6.3.v201404151837-1123206. Please update ADT to the latest version.

No updates were found with "Check for updates". If I try "Install new software", I can see version 23, but I can't upgrade due to the following error:

Cannot complete the install because of a conflicting dependency.
Software being installed: Android Development Tools 23.0.0.1245622 (com.android.ide.eclipse.adt.feature.feature.group 23.0.0.1245622)

After download of the last ADT from the web site, it seems there's another problem.

With SDK Tools rev. 23 proguard is not installed, the folder SDK dir/tools/proguard is missing, and other tools are missing. This version contains several bugs.

Answer 1

Google has released ADT v23.0.2. This solved many problems of previous ADT version 23.

Step-by-step:

• Menu Help → Install New Software...
• For "Work with", select the Android source https://dl-ssl.google.com/android/eclipse
• Tick ADT v23.0 for installation, then click "Next"
• Eclipse will show "Install Remediation Page" since there is conflict with previous version. (If it does not, see below.) Select "Update my installation to be compatible with items being installed" to uninstall the old version and install the new one. After that, proceed with the usual steps.

Note: When I installed the new version of ADT, I didn't include the new version of "Android Native Development Tools" package. Instead, I installed the rest of packages first, and then installed "Android Native Development Tools". For a reason, if I try to install all the new packages including "Android Native Development Tools", the installation fails.

If there is no "Remediation page", the only way to remove the ADT plugin from Eclipse is to go to menu Help → About Eclipse → Installation Details and uninstall from there. But there is a risk of uninstalling Eclipse itself.

Google response:

This is a packaging bug. The entire proguard file is missing. We'll have an update asap, but until then just copy it over from a previous version of the tools:

• http://dl.google.com/android/android-sdk_r22.6.2-linux.tgz
• http://dl.google.com/android/android-sdk_r22.6.2-windows.zip
• http://dl.google.com/android/android-sdk_r22.6.2-macosx.zip

and copy over the following files:

• tools/hprof-conv
• tools/support/annotations.jar
• tools/proguard

So at the end if you started from a new ADT copy by hand the files :)

Edit: with the latest ADT release, the bundle should now work with auto-update, so install these new versions:

• linux 64 bit vm: http://dl.google.com/android/adt/adt-bundle-linux-x86_64-20140702.zip
• linux 32 bit vm: http://dl.google.com/android/adt/adt-bundle-linux-x86-20140702.zip
• mac: http://dl.google.com/android/adt/adt-bundle-mac-x86_64-20140702.zip
• win32: http://dl.google.com/android/adt/adt-bundle-windows-x86-20140702.zip
• win64: http://dl.google.com/android/adt/adt-bundle-windows-x86_64-20140702.zip

Don't try to upgrade from previous version because it doesn’t work at all. If you have got problems with zipalign, it's now under build-tools and no more under tools/ so you can do a symbolic link or just copy it into the expected folder.
