Can I run android emulator without an android phone? I have installed android studio and I've already installed android virtual device. However, when I try to run it, it gives an error like this :
Couldn't start project on Android: Error running adb: No Android device found. Please connect a device and follow the instructions here to enable USB debugging: https://developer.android.com/studio/run/device.html#developer-device-options. If you are using Genymotion go to Settings -> ADB, select "Use custom Android SDK tools", and point it at your Android SDK directory.
I just want to see the emulator in my pc without usb. I have an iPhone but it just shows up in my phone not in my pc using expo scan barcode. I don't want to do that because in my opinion it's not comfortable for debugging etc. I am using windows in my pc so I can't use iOS for emulator.
how to run expo android emulator on windows?
Yes you can:-(With zero android studio config)
- Install expo-cli globally.
- Install android Studio.
- Create a project by running expo-cli init
- No need of any configuration on android Studio.
- Open existing Project from android studio
- then Open the created expo Project it will be available as an android project with a android logo on it
then open the AVD Manager
Download and install whichever device you want but see to that its above android N and do it for x86
- after Installing the desired emulator
- run the emulator before running the project
- then run expo start to start the Project
Go to the metro builder and say run android
if it doesn't run on the first go or if you get error close the project from emulator from recents and do a run on android again from metro builder don't close project just the running project from recent on emulator
- then it should work
Delete the directory C:\Users\Rizwan.expo\android-apk-cache and opening the project on android again It will run
