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.
