Debugging is slow on real android device without attached debugger #25233

forki · 2019-06-12T08:29:40Z

React Native version: 0.59 (but also all others)

Steps To Reproduce

Use real device for testing
react-native run-android
see that app is very slow on the device

Describe what you expected to happen:

Same performance as with attached remote debugger or at least a command line option to react native cli that starts the app with debugger attached.

Workaround

adb shell input keyevent 82
press "DebugJS remotely"
see that app now performs much faster

DebugJS remotely will run/process JS on your computer, not a phone, and render results on the device. This might be caused by hardware specs of your device.

ilya-bmi · 2019-06-22T16:57:31Z

In my case, stacktrace-parser module causes the problem.
Downgrade to "[email protected]" solved the problem.

forki · 2019-07-10T06:04:54Z

@dulmandakh why did you close?
why can't you provide at least a command line option to react native cli that starts the app with debugger attached? This would help so much

IanOnFire · 2019-07-19T12:19:04Z

I don't think this is caused by hardware specs of the device, because even on high-end Android devices I experience really bad performance in debug builds.

Please do notice that this only concerns debug builds, we're experiencing this after updating to [email protected]. After connecting a js debugger the expected performance will return.
This problem will persist, regardless if we enable or disable the use of Hermes engine.

We are also seeing issue on RN 0.60.4 @dulmandakh, please consider re-opening as it affects all devices, no matter their specs

Same here.

In my configuration Hermes is disabled. Yet the issue is the same.

Same.
In addition, the behavior changes depending on whether debugging is enabled or not.
