Answer 1

为什么生成的 apk 这么大？

如 documentation by barteksc/AndroidPdfViewer 中所述

Android PdfViewer depends on PdfiumAndroid, which is set of nativelibraries (almost 16 MB) for many architectures. Apk must contain allthis libraries to run on every device available on market.Fortunately, Google Play allows us to upload multiple apks, e.g. oneper every architecture. There is good article on automaticallysplitting your application into multiple apks, available here.Most important section is Improving multiple APKs creation andversionCode handling with APK Splits, but whole article is worthreading. You only need to do this in your application, no need forforking PdfiumAndroid or so.
