dadb.AdbStreamClosed Exception after first test run

[F-Goncalves]

Hi, whenever I run maestro test I can only run it once successfully. Every consecutive run fails with a dadb.AdbStreamClosed Exception. Only restarting the Android Emulator solves this. But every second time I run the test the same exception occurs.

Exception in thread "pool-2-thread-1" dadb.AdbStreamClosed: ADB stream is closed for localId: 543f194d at dadb.MessageQueue.poll(MessageQueue.kt:76) at dadb.MessageQueue.take(MessageQueue.kt:37) at dadb.AdbConnection.open(AdbConnection.kt:48) at dadb.DadbImpl.open(DadbImpl.kt:31) at dadb.forwarding.TcpForwarder.handleForwarding$lambda-1(TcpForwarder.kt:64) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:829)

Any advice on how to solve this?

This is just a guess, but do you perhaps run maestro hierarchy during the test?

[F-Goncalves]

No I didn't. I didn't even know about that command when I encountered this exception.

What kind of emulator are you using? API version, with/without Google Play, what "device" model, etc.

[F-Goncalves]

Pixel 3a API 32 arm64-v8a with Google Play

Could an IDE that was previously debugging on the same emulator be an issue?

[dmitry-zaitsev]

Unlikely, but it could be related to the fact that this is an ARM emulator or the fact that this is API 32. If you could try the following, it would be a great help:

• Check if a new emulator with the same exact configuration works
• If not, does API 30 work?
