Solve Android error: Unknown option '-No-crunch'

Recently, the official website of Android developer provides the ADT 14 upgrade package. Many of you have chosen to upgrade the package. Then, during development, the following error message appears in the compilation project:

Android error:
Unknown option '-- no-crunch'

 Android asset packaging Tool

Usage:

Aapt L [ist] [-V] [-A] file. {zip, jar, APK}

To sum up, the reason is that only the ADT is updated and the android SDK tools and Android SDK platform-tools are not updated in a timely manner. Therefore, the solution is to open the SDK manager, update the two plug-ins in the tools folder, and restart them to solve the problem.
