Research direction

Start with EditableFileAbstraction.java:62 and TextEditorActivity.java:140, where the crash stack shows the provider access during text-editor startup. Reproduce the reported launch failure on Android 9 if possible and trace the FileProvider configuration and access path. Done means the text editor no longer crashes with this SecurityException.
