How do I “shake” an Android device within the Andr

问题:

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)

回答1:

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

回答2:

With a React Native running in the emulator,
Press ctrl+m (for Linux, I suppose it's the same for Windows and ⌘+m for Mac OS X) or run the following in terminal:

adb shell input keyevent 82

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.

'Ctrl + m' works for Windows in the Android emulator to bring up the React-Native developer menu.

Couldn't find that documented anywhere. Found my way here, guessed the rest... Good grief.

By the way: OP: You didn't mention what OS you were on.

回答5:

'Command + M' for OSX is working for me.

回答6:

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.

回答7:

on linux ctrl+m should work but it doesn't for solving the problem click on the (...) (its extended controls) and then close that window.now you can open menu by ctrl+m. then:

1. click on the (...) (its extended controls)

2. close extended controls

3. ctrl+m

回答8:

For Linux you click on the three dots "..." beside the emulator, on Virtual sensors check "Move" and then try quickly moving either x, y or z coordinates.

回答9:

I am on Mac OS so when I press Command, it enable zooming option. Here is my solution

• Open Configuration window [...] button
• Go toSettings tab ->General tab -> Send keyboard shortcuts to field
• Change value to Virtual device" as shown in the picture

After that focus on the emulator and press Command + M, the dev menu appears.
