The problem is related to the fact that the APK files you are trying to install are not compatible with the Techno P3 phone. It doesn't matter whether these APK files are Android installation packages. These packages also have system requirements and most likely the error is caused due to the CPU compatibility. Try using Google Play Store to install the applications because you have all the specifications mentioned on the application pages, and you can use that information to see if it's compatible with your phone or not.
