Q:

Error parsing package when installing my app

So I get this weird error when I try to install the signed apk file on my android Xperia z3 device. I have sat with this for 6 hours now and I don't find a solution to all the posts from earlier problems. What is actually going on? downloading the apk file from a project in the android studio I made was 1 button click. And here with xamarin????
I really need help with this. The project runs on emulator inside vs on both debug and release options. no errors from the output.
These are the set targets for max and min android versions. https://gyazo.com/fc82fd6c6edced442bd8a790166d3e03
My Xperia is running on 6.0.3
"There was a problem parsing the package". 
Please help

This error usually happens when install the unsign apk. I think there are something went wrong when you sign the apk. You could follow this tutorial : Manually Signing the APK to sign it manually. Since you have already run the app in the emulator, you could get the signed apk in ...\projcetfolder\bin\Release and use it install your app.
