Deployment Parsing error


this is my first time posting something here, sorry in advance for doing something wrong or giving not enough information.

I currently try to make a cardboard app for an assignment.
Packaging the project works fine, but installing it on my phone always reults in getting the error message “Parsing error. While parsing the package an error occured” on my phone display.

I’m using unreal engine 4.14.3, installed Android API 24, Android NDK 12b and JDK 1.8 with code works. My phone is an huawei honor 7 with android 6.0.

I would be glad to receive some tips
