uBlock: a fast, lightweight, and lean blocker for Chrome, Firefox
uBlock: a fast, lightweight, and lean blocker for Chrome, Firefox, and Safari. Available on the Chrome Web Store or for manual installation. Available to install from the homepage. Available for install from the homepage or from the App Store. Available on the Firefox Add-ons site, or for manual installation. Opera shares Chrome's underlying engine, so you can install uBlock simply by grabbing the latest release for Chrome.To benefit from uBlock's higher efficiency, it's advised that you don't use other blockers at the same time (such as AdBlock or Adblock Plus). uBlock will do as well or better than most popular ad blockers. It's important to note that blocking ads is not theft. Don't fall for this creepy idea. The ultimate logical consequence of blocking = theft is the criminalisation of the inalienable right to privacy. -

Bash and Zsh completion support for Gradle. This provides fast tab completion for: Gradle tasks for the current project and sub-projects. Gradle CLI switches (e.g. --parallel). Common Gradle properties (e.g. -Dorg.gradle.debug) It also handles custom default build files, so rootProject.buildFileName = 'build.gradle.kts' is supported. See instructions for bash or for zsh, then consider optional additional configuration. Download and place the plugin and completion script into your oh-my-zsh plugins directory. Completion cache initialization happens the first time you invoke completion and usually takes a few seconds, depending on the size of your project. You can manually initialize the cache and avoid interrupting your development mojo. Tab completion checks known build scripts to see if they've been changed and refreshes the task cache if so. -

Android Easy MultiDex
Android, multidex, splitdex, subpackage plugin
Android, multidex, splitdex, subpackage plugin. The Gradle script was integrated into the plug-in, so that only one configuration file needs to be maintained. Readers can choose separate configuration or integrated configuration according to their own needs. In this way, we maintain the number of methods of the main Dex at about 15,000, and we no longer have to worry about the number of methods. Through the above official subcontracting, the original Dex has been divided into 1 master Dex and more slave Dex. The main Dex contains all 4 major components, Application, Annotation, multidex, etc. and their necessary direct dependencies. Since the number of our methods has reached 16W, hundreds of activities were all stuffed into the main Dex, and the main Dex was successfully exploded. -
