Mayelana nalolu hlelo lokusebenza
Isibukeli se-PDF esilula se-Android esisekelwe ku-pdf.js nabahlinzeki bokuqukethwe. Uhlelo lokusebenza aludingi izimvume. Ukusakaza kwe-PDF kufakwa ku-WebView ene-sandbox ngaphandle kokuyinikeza ukufinyelela kunethiwekhi, amafayela, abahlinzeki bokuqukethwe nanoma iyiphi enye idatha.
I-Content-Security-Policy isetshenziselwa ukuphoqelela ukuthi izakhiwo ze-JavaScript nezici zesitayela ngaphakathi kwe-WebView zingokuqukethwe okumile ngokuphelele okuvela kumafa we-APK kanye nokuvinjwa kwamafonti angokwezifiso njengoba i-pdf.js isingatha ukuzinikezela ngokwazo.
Iphinda isebenzise isitaki esiqinile sokunikeza i-Chromium kuyilapho iveza kuphela isethi encane yendawo yokuhlasela uma iqhathaniswa nokuqukethwe kwewebhu kwangempela. Ikhodi yokunikezela ye-PDF ngokwayo iphephile ngenkumbulo futhi ukuhlolwa kwekhodi okuguquguqukayo kukhutshaziwe, futhi noma umhlaseli ezuze ukusetshenziswa kwekhodi ngokusebenzisa injini enikeza iwebhu eyisisekelo, ungaphakathi kwebhokisi lesinikezeli le-Chromium elinokufinyelela okuncane kunalokho obekungaba nakho ngaphakathi kwesiphequluli.

Kubuyekezwe ngo-
Ukuphepha kuqala ngokuqonda ukuthi onjiniyela baqoqa futhi babelane kanjani ngedatha yakho. Ubumfihlo bedatha nezinqubo zokuphepha zingahluka kuye ngokusebenzisa kwakho, isifunda, nobudala. Unjiniyela unikeze lolu lwazi futhi angalubuyekeza ngokuhamba kwesikhathi.
Ayikho idatha eyabiwe nezinkampani zangaphandle
Funda kabanzi mayelana nendlela onjiniyela abaveza ngayo ukwabelana
Ayikho idatha eqoqiwe
Funda kabanzi mayelana nokuthi onjiniyela bakuveza kanjani ukuqoqwa
