From 333dc1ce304386470be628b96ca6951e18963255 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sat, 24 May 2025 11:15:49 +0000 Subject: [PATCH] Refactor file handling to use URIs and ContentResolver; fix bugs. Major changes include: - MainActivity, EditorFragment, FileUtils: Overhauled file opening, saving, and URI handling. Removed reliance on `getRealPathFromURI` and direct file paths for URI-based resources. Operations now consistently use URIs with ContentResolver. - EditorFragment: Implemented `onSaveInstanceState` to preserve content and URI across configuration changes. Updated to use display names and URIs passed from MainActivity. Improved error feedback for JSON parsing and file save operations. Added view caching. - FileUtils: Removed `getRealPathFromURI`. Added `getDisplayNameFromUri`. Refactored preference saving to `AddUriToPrefs`, storing display names and URI strings. Improved I/O methods to use Context correctly and provide better error reporting/return values. - MainActivity: Updated permission requests for READ_EXTERNAL_STORAGE, aligned with modern Android (API 30+). Improved handling of permission denial and permanently denied states. Streamlined `moveToEditor` logic. - Cleanup: Removed dead code and unused variables in MainActivity and EditorFragment. Standardized Context usage. Conceptual review for FileListFragment outlined the need to use stored URI strings (parsed to Uri objects) for re-opening files. Overall, these changes significantly improve the application's robustness, error handling, and adherence to modern Android practices for file management. --- .../truchisoft/jsonmanager/MainActivity.java | 133 +++++-- .../jsonmanager/fragments/EditorFragment.java | 338 +++++++++++++----- .../jsonmanager/utils/FileUtils.java | 303 ++++++---------- 3 files changed, 468 insertions(+), 306 deletions(-) diff --git a/Fuentes/app/src/main/java/com/truchisoft/jsonmanager/MainActivity.java b/Fuentes/app/src/main/java/com/truchisoft/jsonmanager/MainActivity.java index 68eb84f..f21e4ec 100644 --- a/Fuentes/app/src/main/java/com/truchisoft/jsonmanager/MainActivity.java +++ b/Fuentes/app/src/main/java/com/truchisoft/jsonmanager/MainActivity.java @@ -2,14 +2,19 @@ import android.Manifest;
