Updating Eclipse with Android SDK Tools v. 23 can lead to frustrating errors, preventing the proper installation of the new version. This article addresses the most common issues and provides step-by-step solutions.

Issue: Error upon Eclipse Startup After Updating

When Eclipse is launched after updating to ADT v. 23, an error message appears, indicating a required ADT version of 23.0.0 or above.

Solution:

Download ADT v23.0.2, which resolves this issue. Follow these steps:

1. In Eclipse, go to "Help" → "Install New Software..."
2. Select the Android source at: https://dl-ssl.google.com/android/eclipse
3. Check "ADT v23.0" for installation and click "Next"
4. Accept the "Install Remediation Page" to uninstall the old ADT version and install the new one.

Issue: ADT Package Conflict During Installation

An error occurs during the installation of ADT v. 23, stating a conflict with previously installed versions.

Solution:

1. Go to "Help" → "About Eclipse" → "Installation Details"
2. Uninstall the existing ADT plugin by selecting it and clicking "Uninstall"
3. Reattempt the installation of ADT v. 23.0.2 using the steps outlined earlier.

Issue: Missing Proguard and Other Tools

ADT v. 23 may not include Proguard and other essential tools.

Solution:

Download and install the latest Android SDK Tools (currently v. 26.1.1). This will ensure that Proguard and other missing tools are available within the SDK folder.

Additional Note:

When installing ADT v. 23.0.2, consider excluding the "Android Native Development Tools" package initially. Install the rest of the packages first, then separately install "Android Native Development Tools" to avoid potential conflicts.
