Version 1.2.2 crashes on launch. SDL splash shows then app throws "Freedroids keeps stoppng" message.

Phone is Galaxy A7 runnig Android 8.

Asking for 9yo who I got obsessed with this Andrew Braybrook classic.

@ZebsTheCat thank you for the report. So just making sure: the Freedroid app worked fine on that same Android Phone before the recent app-upgrade?

ZebsTheCat commented 11 months ago

Yes, Freedroid app worked fine until the update a few weeks ago. It crashes straight after the SDL splash screen. It is an older phone, so understand that it is no longer supported.

According to the play-store developer console, this phone+Android version is still considered 'supported' for this app though, so something else seems to be going wrong.

Progress! I've found an old phone with Android 7.1 and could reproduce the crash there! Should then hopefully make it possible to find and fix the bug :crossed_fingers:

Ok, just to document the origin for the crash and fixes for myself:

Running the app on Android 7, adb logcat shows:

AndroidRuntime: java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "inflateValidate" referenced by "/data/app/net.sourceforge.freedroid-2/lib/arm64/libsdl_image.so"

and digging further shows that newer libpng versions rely on newer (>1.2.8) version of zlib, due to using symbol inflateValidate, which older zlib versions didn't have. Older Androids versions 7, 8 seem to have an older zlib version installed which is why the newer dependency does not get resolved and crashes.

Easiest solution I found was to downgrade to libpng version 1.2.25, which didn't use that newer-zlib functionality, and therefore seems to work fine even on the old Android 7.1.2 phone I tested this one.

This was done checking out tag v1.6.25 of libpng and providing a suitable Android.mk file to make the build work.

Bug-fix release Freedroid-1.2.3 is being prepared.

My own testing and user feedback so far indicates the problem is fixed in v1.2.3, so closing the issue.
