XAMARIN FORMS ERROR INSTALL

Question

Hello, I have a XAMARIN application that is working perfectly on the EMULATOR, but when I copy the APK to a mobile device it says that it cannot install, or sometimes it even installs but does not open. Anyone to give me a tip?

Answer 1

Hello,​

Welcome to our Microsoft Q&A platform!

Based on your description, did you get the "App not installed" error?

If so, please add android:extractNativeLibs="true" to the <application> tag like the following parameter in your AndroidManifest.xml

   <application android:label="YourprojectName.Android" android:theme="@style/MainTheme" android:extractNativeLibs="true"></application>  

This issue is related to changes in the android gradle plugin, which changed the default value from true to false in version 3.6.0 (Source: https://developer.android.com/guide/topics/manifest/application-element#extractNativeLibs).

And when you re-build application and generate a new APK.
If you get the following error.

   Error Found tag id where item is expected  

Please enable the Use incremental Android packaging system(aap2) selection in the Android Options tag. And set Linking to None

Best Regards,

Leon Lu
