React Native: android emulator won't show up developer menu

Question

Cmd-M (in Mac) is supposed to bring up the dev menu in android emulator, but when I press cmd-M, it shows the pan gesture(?) as shown in the screenshot.

How can I open up the react native dev menu?

adb shell input keyevent KEYCODE_MENU doesn't show up the menu either..

I can't find menu button either?

Answer 1

Had exact the same problem and could not open the developer menu neither with ctrl + M nor with adb shell input keyevent 82 . ctrl would also show this strange gesture object.

Turned out I had run the app in non-development mode (done with expo via expo start --no-dev ) and the menu is only enabled in development mode. After expo start --dev it works like a charm.

Answer 2

您可以从模拟器的选项按钮或使用此命令 adb shell input keyevent 82 打开它

Answer 3

I had the same problem,

I was trying a JavaScript function in React Native and I didn't need to render anything for it, my screen was just empty.

Developer menu wasn't opening with Ctrl + M on Windows, when I just try to render a simple text on screen, Ctrl + M started working.

Let's render something.

Answer 4

I was facing the same error and switching to debug mode resolved the issue for me. Reload and developer option won't work if you are testing using release build.

Answer 5

我相信您需要使用Ctrl+D来使用 Android 模拟器打开开发人员设置。

Answer 6

要在 Android 模拟器上打开 Developer 菜单，请在 Mac OS 上的 Android 模拟器中运行时按 ⌘M，在 Windows 和 Linux 上按 Ctrl+M。
