How do I shake an Android device within the Android emulator to bring up the dev menu to debug my React Native app

Question

I am working on a cross-platform React Native mobile app  I am writing console log statements as I develop  I want to see these logging statements in Chrome while I m running the Android app in the default Android emulator  According to Facebook s docs I just need to  shake the device   How do I do this in the Android emulator      To access the in-app developer menu       On iOS shake the device or press control       z in the simulator    On Android shake the device or press hardware menu button  available on older  devices and in most of the emulators  e g  in genymotion you can press     m to  simulate hardware menu button click

As while developing react native apps  we play with the terminal so much  so I added a script in the scripts in the package json file   menu    adb shell input keyevent 82   and I hit   yarn menu   for the menu to appear on the emulator  it will forward the keycode 82 to the emulator via ADB not the optimal way but I like it and felt to share it

It might be not direct solution  but I ve created a lib that allows you to use 3 fingers touch instead of shake to open dev menu  when in development mode  https   github com pie6k react-native-dev-menu-on-touch  You only have to wrap your app inside   import DevMenuOnTouch from  react-native-dev-menu-on-touch      or   import   DevMenuOnTouch   from  react-native-dev-menu-on-touch   class YourRootApp extends Component     render         return          lt DevMenuOnTouch gt           lt YourApp   gt         lt  DevMenuOnTouch gt                 It s really useful when you have to debug on real device and you have co-workers sitting next to you

If you re using the new emulator that comes with Android Studio 2 0  the keyboard shortcut for the menu key is now Cmd M  just like in Genymotion   Alternatively  you can always send a menu button press using adb in a terminal   adb shell input keyevent KEYCODE MENU   Also note that the menu button shortcut isn t a strict requirement  it s just the default behavior provided by the ReactActivity Java class  which is used by default if you created your project with react-native init   Here s the relevant code from onKeyUp in ReactActivity java   if  keyCode    KeyEvent KEYCODE MENU      mReactInstanceManager showDevOptionsDialog      return true      If you re adding React Native to an existing app  documentation here  and you aren t using ReactActivity  you ll need to hook the menu button up in a similar way  You can also call ReactInstanceManager showDevOptionsDialog through any other mechanism  For example  in an app I m working on  I added a dev-only Action Bar menu item that brings up the menu  since I find that more convenient than shaking the device when working on a physical device

Within your app in the Android Emulator press Command   M on macOS or Ctrl   M on Linux and Windows

Use command   m cmd   M  on MAC  Also make sure that you are accessing your application while you try to access the Debug Menui e  your app must be running otherwise Cmd   M will just return the usual ordinary phone menu
