GitHub user breautek added a comment to the discussion: How do I open a saved PDF file on my Android device ?
PDFs are complex binaries, so a pdf viewer software is necessary. The proper "android" way is to use an Intent to open the PDF document, which the user can choose a supported application of their choice (e.g. Adobe Acrobat Reader). Cordova doesn't have an out-of-the-box solution to open intents in a general sense. A cordova plugin will need to expose a way to request for the PDF to be opened using an app capable of reading PDFs. Alternatively, Mozilla as a PDF reader implementation in pure JS using an HTML canvas (https://mozilla.github.io/pdf.js/). This will likely be not very performant if I were to guess, but it could be good enough for your needs and probably worth looking into. The [getDocument](https://mozilla.github.io/pdf.js/api/) API supports data types like an ArrayBuffer so you'd just use the cordova file plugin to read the data as an `ArrayBuffer` then you should be able to pass the ArrayBuffer directly into mozzila's PDF library. ```javascript function readBinaryFile(fileEntry) { fileEntry.file(function (file) { var reader = new FileReader(); reader.onloadend = function() { let data = this.result; // This is the ArrayBuffer }; reader.readAsArrayBuffer(file); }, onErrorReadFile); } ``` GitHub link: https://github.com/apache/cordova/discussions/510#discussioncomment-11331311 ---- This is an automatically sent email for issues@cordova.apache.org.
