my english isn't that good. I am from Turkey and sorry if my question isn't clear to you.
When I run run-android with React Native, I get the following error but when I run run-ios I don't get any issue. I am using a Mac computer.
Thank you for your help.

I think you should uninstall the app on any emulator or devices, after that please re-run app.
It might be caused by having package.lock.json and yarn.lock at the same time

Hello,
Anas Ahmed here, I was installing bugsnag-expo-cli-init in my react native app at first it asked me 3 ques and then at the time of installing it gave me this error can anyone help me in this. Installing in npm
Are you attempting to run the bugsnag-expo-cli on Windows? Bugsnag's Expo CLI currently only supports Linux and Mac:
https://docs.bugsnag.com/platforms/react-native/expo/#installation-and-configuration
As an alternative to the CLI, you could follow the manual integration guide:
https://docs.bugsnag.com/platforms/react-native/expo/manual-setup/

As this answer says:
There seems to be an issue with the latest version of #react-native-community/cli-platform-android 3.1.1.
I have resolved my issue by downgrading to an older version of the library by adding this to my package.json.
"resolutions": {
"#react-native-community/cli-platform-android": "2.9.0"
}
After that, remove the node_modules folder and run yarn or npm install again.
////
I set jdk path in environment variables.
But the app could not be installed.
I have tried many times.
But the bugs are still there.do reply if there is any solution.

I keep getting

your PATH
Whenever I try to run react-native code from my terminal to use an android emulator.
I've recently been trying to set up react-native on my laptop through wsl because the virtual box has been giving me trouble using it.
I've set my ANDROID_PATH to C:\Users\username\AppData\Local\Android\Sdk and my JAVA_PATH to D:\Program Files\Java\jdk-13.0.1. But I keep getting the error.

Please help
Your JAVA_HOME is set incorrectly, go through the setup again, everything should works...
You can refer to this and check what is missing...
