react.gradle automatically build your javascript and copy any resources imported inside your javascript to the build folder so make sure to NOT call react-native bundle manually and delete any files or folder as src/main/res/drawable-* and src/main/assets/*.bundle and have the following changes into your app/bundle.gradle

project.ext.react = [
  entryFile      : "index.js", // or index.android.js
  bundleInRelease: true,
  bundleInDebug: true
]

apply from: "../../node_modules/react-native/react.gradle"

Note: please notice that some react-native versions have a problem with the local cli.js please make sure to upgrade to a newer version or try adding the following config

 project.ext.react = [
    // ...
    cliPath: "node_modules/react-native/local-cli/cli.js"
 ]
