LP Builder is a Windows tool to decode APKs, edit text, URLs and logos, change app names and package IDs, then rebuild and sign APK or AAB files. Includes organized projects, saved versions, signing certificate fingerprints and automatic update notifications.








V1.5.2

From v1.3.0 to v1.5.2, LP Builder gained:
- App identity editing: change the app’s display name and package name, with a review of affected files and compatibility notes.
- Build improvements: fixes for resource compilation, APK packaging, alignment, and installation issues.
- Signing fingerprints: view and copy the signing certificate’s SHA-1 and SHA-256 for Google services.
- Update notifications: check the forum at startup, skip checks offline, and show an Update now button when a newer release is found.
- Ads tab: scan supported advertising components, review findings, disable selected items, and restore the checkpoint.
- Image improvements: safer logo replacement, handling of locked/read-only files, and opening images in Windows by button or double-click.
- Clear operation feedback: animated loading, elapsed time, and lasting completion, failure, or cancellation messages.
- Translate tab: manually translate offline or use your own Google Cloud Translation API key. Review results, preserve placeholders, and save checkpoints before applying.
- Translation search: filter scanned text by words or phrases without losing edits or selections.
- Project cleanup: delete individual projects or saved versions through confirmation and the Windows Recycle Bin.
