Doesn't launch the daemon

[rkfg]

On my Nexus 10 with Android 5.1 all I have is this:

I waited for several minutes and tapped the link, nothing changed. /sdcard/Android/data/com.mfreitas.twister/files/ is empty. I don't know how long it starts (if it runs at all, there's no indication of that). Tried on Nexus 4 (Android 5.0), all the same. Would be good to show some heartbeat instead of an error page.

do you have a console (terminal) installed?

if so, would you try running the command '/data/app/com.mfreitas.twister-2/lib/arm/libtwisterd.so' directly?

also please post the result of 'ls -l /data/app/com.mfreitas.twister-2/lib/arm/libtwisterd.so'

don't be fooled by the .so extension, this is an executable... the problem i've seen is that the .so "trick" (to get the executable bit set) may not work on never androids. if you could please confirm that it would be nice.

i believe the apk may need to use a different technique, for example, unziping the executable somewhere and then chmod +x it.

[rkfg]

I've run adb shell, much easier and the effect is basically the same.

$ ls -l /data/app/com.mfreitas.twister-2/lib/arm/libtwisterd.so
-rwxr-xr-x system system 11621004 1979-12-31 17:21 libtwisterd.so

Launching it results in the following:
error: only position independent executables (PIE) are supported.

Looks like Google restricted some binary features.

Same issue here.
Wanna help to have a functionally apk but how?
Nice job!

[miguelfreitas]

Good catch! It seems it should be easy to fix, provided we want to live with supporting only Android 4.1+

You may try to recompile it using this pre-configured virtualbox image:
