message: Add documentation for gradle
diff: @@ -100,3 +100,21 @@ We enable the gradle integration in your ``android/app/build.gradle`` file
  by adding the following line after the ``react.gradle`` one::
  apply from: "../../node_modules/react-native-sentry/sentry.gradle"
  +
  +You can also enable logging for ``sentry-cli`` by adding this config before the above
  +``apply from:`` line.
  +
  + project.ext.sentry = [
  + logLevel: "debug"
  + ]
  +
  +We also support fetching different ``sentry.properties`` files for different flavors.
  +For that you need to add:
  +
  + project.ext.sentry = [
  + logLevel: "debug",
  + flavorAware: true
  + ]
  +
  +We recommend leaving ``logLevel: "debug"`` since we look for specific ``sentry.properties``
  +files depending on your flavors name.
