關於 PDF Viewer
PDF Viewer（包名：app.grapheneos.pdfviewer.play）開發者是GrapheneOS，PDF Viewer的最新版本31更新時間為2025年08月31日。Secure PDF Viewer的分類是生產應用。您可以查看Secure PDF Viewer的開發者下的所有應用。目前這個應用免費。該應用可以從APKFab或Google Play下載到Android 8.0+。APKFab.com的所有APK/XAPK文檔都是原始文檔並且100%安全下載的資源。
基於 pdf.js 和內容提供者的簡單 Android PDF 檢視器。該應用程式不需要任何權限。 PDF 流被饋送到沙盒 WebView 中，而不授予其存取網路、文件、內容提供者或任何其他資料的權限。
Content-Security-Policy 用於強制 WebView 中的 JavaScript 和樣式屬性完全是來自 APK 資產的靜態內容，並阻止自訂字體，因為 pdf.js 會自行處理渲染這些字體。
它重複使用了強化的 Chromium 渲染堆疊，同時僅暴露與實際 Web 內容相比的攻擊面的一小部分。 PDF 渲染程式碼本身是記憶體安全的，停用了動態程式碼評估，即使攻擊者確實透過利用底層 Web 渲染引擎獲得了程式碼執行權，他們也位於 Chromium 渲染器沙箱中，其存取權限比瀏覽器中的存取權限要少。
