Hello,
I have recently bought a xpc nano NS02E (Android 8.1) from Shuttle for signage purposes. It unfortunately can't read PDF files. The help desk of the signage software I'm using (Xibo) has confirmed me that it uses Android System WebView to display PDF files.
The Android System WebView installed is the v76 and it uses 14.34ko of internal storage (which seems ridiculously low). The Shuttle box doesn't natively have the Play Store. Therefore I have downloaded the latest WebView apk from various sites but the update always ends with "App not installed".
Do you think of any other way to update Android System WebView ?
Thanks in advance :)
Sounds like you have a regular Android box and not an official "AndroidTV" STB. The distinction is huge because non-AndroidTV box uses the OpenSource AOSP version of Android. With AOSP the Android System WebView can only be updated if device has root access to replace the system app manually. In official AndroidTV you get WebView updates from the Google Play Store and it uses the licensed version with "Google" in the package name. <com.google.android.webview> Vs. <com.android.webview>
Two solutions for you, 1- if have Root access is use file manager to delete APK from '/system/app/' and install the latest AOSP version from Bromite.org (read guide for replacing WebView on website) renamed file to match the file it replaces; 2- install the official "Google" WebView and see if in settings developer options let's you change the WebView app then reboot and see if setting persists, which may need further modification through ADB.
