AsyncStorage hangs infinitely on real device in debug mode.

Environment

Environment:
OS: Windows 10
Node: 8.11.1
Yarn: 1.9.4
npm: 6.0.1
Watchman: Not Found
Xcode: N/A
Android Studio: Not Found

Packages: (wanted => installed)
react: ^16.3.0-alpha.1 => 16.3.0
react-native: 0.54.0 => 0.54.0

Description

The code that hangs infinitely:

return AsyncStorage
      .multiRemove(['param1', 'param2'], (error) => console.warn("Problem with clearing state: ", error))
      .then(() => console.log('cleared storage'));

• Tested on real devices (one plus, lenovo tablet, ZTE, ... every tested phone so far has it).
• Happens a lot more on windows
• With 'Chrome Debugger' and 'React Native Debugger'
• Doesn't happen all the time, but when it does, it happens A LOT (like 30 times in row)
• Even after cleaning the project, uninstalling the app, rebuilding, cleaning the storage: nothing helps.
• Seems to happen a lot more if an error occurred (which happens 1/2 on first start up), and you reload afterwards
• The params are not necessarily available in the store at that time, but it doesn't seem to matter
• This happens to be the first AsyncStorage call of the app. by removing it, it happens at the next one.

Reproducible Demo

Really hard to reproduce, but I suppose: any project which is developed and debugged on a real device.

By the way:

• We must use a real device, since our app requires bluetooth
• This costs us at least 1 hour a day / person, if we cannot fix it within the month, we will look into implementing another version of SQLite or step away from react-native altogether.

It looks like you are using an older version of React Native. Please update to the latest release, v0.57 and verify if the issue still exists.

The ":rewind:Old Version" label will be removed automatically once you edit your original post with the results of running react-native info on a project using the latest release.

Hi, we tried to update to version 56 when it got released, but it was not supported on windows yet. There was a aplha version of 57 back then, but that was even worse. (see #20015, #19669, #19654, ...)

But I noticed now, that on the 57 both are in the changelist:

• Fix issue with AsyncStorage not behaving properly on Android 7+ (1b09bd7)
• Fixed builds on Windows machines (3ac86c3 by @rafeca)

So i'll try indeed to update to the 57. Since half of the dependencies will be broken as usual, this will take a few days probably, I'll give feedback once it happened

Let's reopen once you're on the current version.
