Google waging war on malicious apps

Late last month, Google made sweeping changes to its policies for developers on Play, the official store for apps that run on Android, Google’s smartphone operating system. The changes, which among other things affect how ads are displayed and permissions sought, are meant to make Android safer so users can download and use apps with confidence. Developers have until later this month to make the changes. Those that run afoul of the new rules after the deadline will find their apps deleted.
