ADB exited with exit code 1

Question

I'm getting the following error when running my flutter project on Android Emulator. It works fine on iOS Simulator and the project is also fine on my other Mac (runs on both Android and iOS Simulator)

Error: ADB exited with exit code 1 Performing Streamed Install

adb: failed to install /Users/xxxx/Dropbox/Flutter/test_app/build/app/outputs/apk/app.apk: Error launching application on Android SDK built for x86.

I've cleaned my project and reset my emulator but no luck. It only affects my mac book pro android build.

Flutter doctor also shows no issues

Answer 1

I know two reason that lead to this error :

• Maybe your device/emulator's storage is full. Try deleting some apps or similar to free up storage.

Or

• Invalid package name . for example using capital letter in package name. use this to change package name in flutter

Answer 2

FAST SOLUTION (worth trying quickly before attempting more complex solutions):

run the command flutter clean
