On my XA2 rights are same your ls -al. I think you need to use devel-su with touch command since nemo don’t have reading rights.
@inte Have you seen any progress on this. After several week of running on 3.4.0 without issues, suddenly I Android apps refuse to install.
Trying to install it from AlienDalvicControl -> Downloads tells me that there was an error parsing the package.
Actually I checked Alien Dalvik’s log via lxc-attach -n aliendalvik -- /system/bin/logcat. It seems that installation fails due to low memory. At least I get these messages in the log:

So why does lowmemorykiller fail?
After some unstructured research I found that within the lxc container of Alien Dalvik there’s a directory /data/app which contains some APK data. Most of the directories can directly be mapped to an installed app. However there was a directory called vmdl2083684193.tmp with an empty file with the name of the latest apk package that failed to install. So I deleted that directory and managed to install the app and others as well.
That directory is also available on the Sailfish side at /home/.android/data/app
Hence, if you run into the same problem, make sure there are no stale directores in the form /home/.android/data/app/vmdl??????????.tmp.
Hope that helps someone eventually

Thank you for your updates. I have to admit that I didn’t investigate the issue further since install through alien dalvik control worked fine for me.
I don’t have much time currently due to work, family and… christmas:)

Solution from jollajo worked for me aswell,
had also vmdl???????.tmp folder in /home/.android/data/app.
THX 
Helped me, thanks a lot!
You’re the boss. That fixed my troubles with Aurora and F-Droid apps (Xperia XA2, Sailfish 4.0.1.48): they stopped working, even refusing to download stuff, after a somewhat buggy F-Droid update.
But I didn’t have any “.tmp” directories into /data/app. I just stopped Alien Dalvik, logged in as root (devel-su) in the terminal and moved every directory created during the last hour (ls -l /home/.android/data/app) to another folder. I could have deleted them, but I like to play safe.
Started the Android Support again and I was able to normally install/update stuff with Aurora app.

So how do I access the .android/data folder?
I got the same question as kissamies. As a non-developer, I am trying to understand all your posted possible solutions here (thanks a lot!) but I can’t access the folder .android/data. The file browser says that I have to right to read the content. Any tips for someone who is not that familiar with the terminal 
?
I’d suggest you activate Developer mode and Remote connection from Developer Tools from Settings. With that activated you can connect to your phone via SSH via USB or WIFI. Change to root via devel-su and change to the desired directory.
It’s quite a bit of fiddelling to get there, so probably not a way to go if you don’t have any experience with Linux or the joy of fiddelling. Wish you good luck.
Even if I activate the developer mode and devel-su in the terminal, I can’t access .android folder with the StartAsRoot for File-browser. It says I have no permission. No matter what I do. I used to be able to access the root directory when I fiddled with something way over a year ago, but now I have no access.
