Revision history [back]

Hi there,

i have a weird problem on my j1. From one minute to the other i can't start an app. The problem is with threema - so its an android app - which is the only one i installed by hand by downloading apk. All other android apps are downloaded via app store. Still it worked fine until it couldn't start for whatever reason - it shows loading and then just stops without the app opening. Already restarted several times.

I did no updates, didn't install or deinstall anything. Nothing. All i did was cleaning the micro usb port by hand from some dust. But if that would be the reason.... I read some others threads where they did start other android apps and not the problematic one as solution. Doesn't work either.

Anyone got an idea what i can do? Never had a problem like that. Starting problems with some apps - but nothing that a reboot didn't fix.

Edit 1: I tried emptying cache as suggested in the comments. No change

I also locked in via ssh from my desktop pc and looked how to start android apps. (browse to /usr/share/applications -> open the needed .desktop file via editor (i used nano) -> see the apkd-launcher entry) I tried starting 2 android apps via terminal from desktop with the info out of the .desktop files 1. files

1. my rss-reader [nemo@Sailfish ~]$ apkd-launcher "/data/app/org.freshrss.easyrss-1.apk" org.freshrss.easyrss/org.freshrss.easyrss.Home Result: Parcel(00000000 '....') -> loads a few seconds - then the app starts on J1

   1. threema [nemo@Sailfish ~]$ apkd-launcher "/data/app/ch.threema.app-2.apk" ch.threema.app/ch.threema.app.activities.MainActivity Result: Parcel(00000000 '....') [nemo@Sailfish ~]$ -> jumps straight back to the prompt. no loading time at all.
