Google wants to help developers build better apps with the introduction of new runtime permissions. The new permissions will be replacing the existing install-time permissions model in the company’s upcoming operating system, Android 6.0 Marshmallow.

“Runtime permissions give your app the ability to control when and with what context you’ll ask for permissions,” wrote Ian Lake, developer advocate at Google, in a blog post. “This means that users installing your app from Google Play will not be required to accept a list of permissions before installing your app, making it easy for users to get directly into your app.”

In addition, the company is providing new permission design guidelines to give developers best practices for asking and using permissions.
