📄 crates/tauri/src/app/plugin.rs:138-140

The code at lines 139-140 creates a shared reference to handle then attempts to dereference it with *handle_ref:

let handle = _api.register_android_plugin("app.tauri", "AppPlugin")?;
let handle_ref = &handle;
_app.manage(AppPlugin(*handle_ref));

PluginHandle<R> implements Clone but not Copy (confirmed in plugin.rs), so *handle_ref attempts to move out of a shared reference, which is a compile error: "cannot move out of *handle_ref which is behind a shared reference".

This code is behind #[cfg(target_os = "android")] so it only fails when compiling for Android targets, which may explain why it passed CI on other platforms.

The fix is to simply move handle directly, matching the existing pattern used in path/plugin.rs:

let handle = _api.register_android_plugin("app.tauri", "AppPlugin")?;
_app.manage(AppPlugin(handle));

        let handle = _api.register_android_plugin("app.tauri", "AppPlugin")?;
        _app.manage(AppPlugin(handle));

📄 crates/tauri/mobile/android/src/main/java/app/tauri/AppPlugin.kt:35 🔗 Android docs: Activity.onBackPressed() deprecated in API 33

When no listeners are registered and the webview can't go back, the code disables the callback and calls activity.onBackPressed() (line 35). This method has been deprecated since Android API level 33 (Android 13) in favor of the OnBackPressedDispatcher pattern that is already being used here.

The pattern of temporarily disabling the callback and calling onBackPressed() works as a fallback but will trigger deprecation warnings and may eventually be removed in future Android versions.

A more forward-compatible approach would be to either:

1. Use activity.moveTaskToBack(true) if you just want to background the app
2. Call activity.finish() to close the activity
3. Remove the callback entirely and re-add it, letting the dispatcher handle the default behavior

That said, this is a commonly used workaround in the Android ecosystem for triggering default back behavior from within an OnBackPressedCallback, so it's acceptable for now.
