Update is not implemented.

Error message

Update is not implemented.

What it means

VideoContentProvider exposes search suggestions only; update() unconditionally throws UnsupportedOperationException('Update is not implemented.') because the provider has no writable backing store to update.

Solutions

1. Drop the update() call against this provider; it is query-only by design.
2. Apply state changes through the app's real APIs (media service, playlists, prefs) instead.
3. In a fork, implement update() against actual storage if you truly need it.

Example fix

// before
getContentResolver().update(searchUri, values, null, null); // throws

// after — provider is read-only; push changes through the app's
// own data APIs instead of the search ContentProvider.

// update is unsupported; guard by operation type before dispatch
if (isWriteOperation(op)) {
    require(isWritableProvider(uri)); // search provider is not
}

try {
    getContentResolver().update(searchUri, values, null, null);
} catch (UnsupportedOperationException e) { // Update is not implemented
    Log.w(TAG, "Search provider is read-only: " + searchUri);
}

When it happens

Trigger: Any getContentResolver().update(uri, values, where, args) call against this provider's authority — e.g. a sync adapter trying to push state changes.

Common situations: Sync frameworks attempting bidirectional sync with every provider; maintenance tooling flipping flags through content URIs; tests exercising update on all providers.
