Uploading the debug bundle hands the user a key and nothing else. Users who want to see what the bundle contains before sharing it, or who will not upload from a beta build, have no way to get at it. Add a second action to the Troubleshoot screen that opens the system file picker and writes the bundle where the user chooses. The engine generates the zip into the app cache through the new DebugBundleFile bridge call; the fragment copies it into the picked document and removes the temporary file. On failure the picked document is deleted so no empty file is left behind. Both bundle buttons are disabled while either runs, since they share one generator. The anonymization switch applies to the saved bundle exactly as it does to the uploaded one. Bump the netbird submodule to the commit that adds DebugBundleFile and the stale bundle cleanup. Until that change lands on netbird main the pointer references the branch commit; it has to move to the merged commit before this is merged.
The picker stops the activity, which unbinds the VPN service, so calling the engine from the result callback failed with "VPN service not connected". Generating the zip first leaves the callback with plain file IO, which needs no binder. A spinner covers both the generation and the copy.

Merge Risk: ⚪ Minimal · up to This change adds a debug-bundle-to-file export flow with a system file picker, temporary file cleanup, and progress UI. The reviewed code paths for generation, saving, and cleanup appear sound, and the one edge case investigated turned out to be unreachable given Android's activity-result delivery guarantees.

- Line 627: Update the troubleshoot delegation around debugBundleFile to capture
mBinder in a local variable before the null check, then use that same local for
the null check and delegation. Preserve the existing behavior when the binder is
unavailable while preventing onStop() from causing a race-induced
NullPointerException.

Design is oK. nothing critical.. only two smaller issues.
Apart for this, I don't know if it's possible/worth to test something of it..
As you address the two comments I can stamp

We create the file before to saveDebugBundleTo
registerForActivityResult(
new ActivityResultContracts.CreateDocument("application/zip"), this::saveDebugBundleTo)
so if we return here in line 220 the file is already created.

I'd use "wt" for safety, to ensure we truncate and don't have trail bytes from previous bundle pollute/corrupt.

Uploading a debug bundle hands the user an upload key and nothing else. Users who want to see what the bundle holds before sharing it, or who will not upload from a beta build, have no way to get at the file.
Adds a second action to the Troubleshoot screen that writes the bundle wherever the user picks, through the system file picker. The anonymization switch applies to it exactly as it does to the uploaded bundle.
The engine generates the zip into the app cache before the picker opens. The picker stops the activity, which unbinds the VPN service, so generating afterwards failed with
VPN service not connected— the result callback now only copies a finished file, which needs no binder. A spinner covers both the generation and the copy, and the picked document is deleted on failure so no empty file is left behind. Both bundle buttons are disabled while either action runs, since they share one generator.Depends on netbirdio/netbird#7528, which adds the
DebugBundleFilebridge call, the stale bundle cleanup, and the sync response persistence that makesnetwork_map.jsonappear in Android bundles at all.Summary by CodeRabbit
