I cannot install Locus from the APK file.
I installed the latest version of Locus from Google Play. After some time, I found a bug in Locus and restored Locus from Titanium Backup. But Locus did not start. Error "application crash".
I uploaded an APK file with the older version I needed. I started the installation. The installation did not happen, the error message "package damaged." But I am sure that the file was downloaded without errors.
I deleted Locus and deleted the Locus folder. I started the installation from the APK-file again. Locus is now installed, but Locus did not start again. Error "application crash".
I downloaded the apk file with the latest version. I started the installation. Locus installed, but did not start. Error "application crash".
I installed the Locus version from Google Play again. Everything is working.
My phone is running Android 7 and for a very long time nothing has changed.
There was no such problem before, I could easily install any older version of Locus.
Help me find the reason why I cannot install Locus from the APK file.
