The right code is ```java public CordovaPluginPathHandler getPathHandler() { WebViewAssetLoader.PathHandler pathHandler = path -> { String targetFileSystem = null; if (path.startsWith(LocalFilesystemURL.fsNameToCdvKeyword("persistent"))) { targetFileSystem = "persistent"; } else if (path.startsWith(LocalFilesystemURL.fsNameToCdvKeyword("temporary"))) { targetFileSystem = "temporary"; } else if (path.startsWith(LocalFilesystemURL.fsNameToCdvKeyword("files"))) { targetFileSystem = "files"; } else if (path.startsWith(LocalFilesystemURL.fsNameToCdvKeyword("documents"))) { targetFileSystem = "documents"; } else if (path.startsWith(LocalFilesystemURL.fsNameToCdvKeyword("cache"))) { targetFileSystem = "cache"; } else if (path.startsWith(LocalFilesystemURL.fsNameToCdvKeyword("root"))) { targetFileSystem = "root"; } else if (path.startsWith(LocalFilesystemURL.fsNameToCdvKeyword("files-external"))) { targetFileSystem = "files-external"; } else if (path.startsWith(LocalFilesystemURL.fsNameToCdvKeyword("sdcard"))) { targetFileSystem = "sdcard"; } else if (path.startsWith(LocalFilesystemURL.fsNameToCdvKeyword("cache-external"))) { targetFileSystem = "cache-external"; } else if (path.startsWith(LocalFilesystemURL.fsNameToCdvKeyword("assets"))) { targetFileSystem = "assets"; } // --------------------added start-------------------- else if (path.startsWith(LocalFilesystemURL.fsNameToCdvKeyword("content"))) { targetFileSystem = "content"; } // --------------------added end-------------------- boolean isAssetsFS = targetFileSystem == "assets"; if (targetFileSystem != null) { // Loop the registered file systems to find the target. for (Filesystem fileSystem : filesystems) { /* * When target is discovered: * 1. Transform the url path to the native path * 2. Load the file contents * 3. Get the file mime type * 4. Return the file & mime information back we Web Resources */ if (fileSystem.name.equals(targetFileSystem)) { // E.g. replace __cdvfile_persistent__ with native path "/data/user/0/com.example.file/files/files/" String fileSystemNativeUri = fileSystem.rootUri.toString().replace("file://", ""); String fileTarget = path.replace(LocalFilesystemURL.fsNameToCdvKeyword(targetFileSystem) + "/", fileSystemNativeUri); File file = null; if (isAssetsFS) { fileTarget = fileTarget.replace("/android_asset/", ""); } else { file = new File(fileTarget); } try { // --------------------added start-------------------- if(targetFileSystem == "content") { ContentResolver cr = webView.getContext().getContentResolver(); Uri uri = Uri.parse(fileTarget); InputStream fileIS = new FileInputStream(cr.openFileDescriptor(uri, "r").getFileDescriptor()); String fileMimeType = cr.getType(uri); return new WebResourceResponse(fileMimeType, null, fileIS); } // --------------------added end-------------------- InputStream fileIS = !isAssetsFS ? new FileInputStream(file) : webView.getContext().getAssets().open(fileTarget); String filePath = !isAssetsFS ? file.toString() : fileTarget; Uri fileUri = Uri.parse(filePath); String fileMimeType = getMimeType(fileUri); return new WebResourceResponse(fileMimeType, null, fileIS); } catch (FileNotFoundException e) { Log.e(LOG_TAG, e.getMessage()); } catch (IOException e) { Log.e(LOG_TAG, e.getMessage()); } } } } return null; }; return new CordovaPluginPathHandler(pathHandler); } } ``` -- This is an automated message from the Apache Git Service.
