I also have same issue. Is there any other 16 KB page size compatible pdf viewer lib for android?

We are also searching but not getting it. We tried to fix it but could not succeed. If you find any solution for this then please tell us also.

[PeaceAllen]

[asadwaheed1]

Found a compatible lib

[asadwaheed1]

this one works implementation 'io.github.oothp:android-pdf-viewer:3.2.0-beta05'

You are a hero asadwaheed1! Thank you so much!

[technicalamanpandit]

🙏 Thank you so much @asadwaheed1!

The library you suggested: implementation("io.github.oothp:android-pdf-viewer:3.2.0-beta05") works perfectly and resolves the 16KB native page size issue ✅

Also, the documentation and setup instructions available here were really helpful: 🔗 https://libraries.io/maven/io.github.oothp:android-pdf-viewer

Thanks again for pointing this out — it saved me a lot of time. Much appreciated! 🙌

Just another problem:

When using implementation 'io.github.oothp:android-pdf-viewer:3.2.0-beta05' my styles getting overidden, e.g. colorAccent is used from the library instead of my app...

(correcting the resources at https://github.com/oothp/AndroidPdfViewer/tree/master fixed the problem...)

[asadwaheed1]

@iNeoTroniC Good work. So have you published your fixes in a public repo which we can use?

[asadwaheed1]

I decided to fix it myself here's the bug free version

implementation 'com.github.asadwaheed1:AndroidPdfViewer:v3.2.0-beta06'

[technicalamanpandit]

Which bug has been fixed in this

io.github.oothp:android-pdf-viewer:3.2.0-beta05 solved the 16k issue, but the signature cannot be displayed。Do you have a solution？

Play Store is showing a ‘16KB native page size issue’. Will it be fixed if I add this? Please reply.
