Since Txd Tool is often removed from the Google Play Store due to copyright claims by Rockstar Games or policy violations regarding modding tools, users must download the APK (Android Package Kit) file from third-party sources.
On Android 11 and above (including Android 13), Google restricted direct write access to the Android/data folder. Since GTA SA stores its textures there, you have two options:
Android 13 does not have a universal "Allow from this source" toggle for all apps. Instead, it asks for permission per-app basis when you try to install an APK.
: Native support for operation progress notifications on Android 13+.
: Improved texture processing and fixed uncompressed import issues for devices on Android 11 and higher.
