to find your logs on Android studio

Explanations Logs

  • Failed to download from => same as download_fail
  • notifyAppReady was not called, roll back current bundle => same as as update_fail

Finding the downloaded bundle in your device


To debug on iOS, you need to dump the app on your computer, you can do it like this:

Xcode has a built-in feature for inspecting the file system of developer-installed apps on an iOS device.

To achieve this:

  • Connect your device to your Mac and select Window > Devices in the Xcode menubar.
  • Select your device in the left pane under the Devices section.
  • This will show a list of developer-installed apps for that device.
  • Select the app you want to inspect and then select the gear icon near the bottom of the screen.
  • Here you can view the current file system by selecting Show Container or download a snapshot of it.

Selecting Download Container… will download and export a snapshot of the file system as a .xcappdata file that you can browse through.

Right-click on this file and select Show Package Contents to open the folder.

Open the App Data folder, and you should now see a few folders like Documents, Library, tmp, etc.


Then you will find a version in 2 folders:

library/NoCloud/ionic_built_snapshots is necessary after the app reboot

and documents/versions for hot reload


To debug on Android, you need to access the device from Android Studio:

  • Click View > Tool Windows > Device File Explorer or click the Device File Explorer button in the tool window bar to open the Device File Explorer.
  • Select a device from the dropdown list.
  • Open the path data/data/APP_NAME/ where APP_NAME is your app ID.


Then Find the versions folder to see all the versions
