Ionic build failure due to Manifest merger failed

[anshuman]

This worked:

Firebase App unable to Compile on Android with AAPT error

Finally found a solution, based on a response from SO: I may have deleted platforms folder beforehand Run: ionic cordova platform rm android Run: ionic cordova platform add android@8.0.0 Run: ionic cordova plugin add cordova-plugin-androidx Run: ionic cordova plugin add cordova-plugin-androidx-adapter Make sure your gradle.properties has: cdvMinSdkVersion=19 Make sure your build.gradle has: project.ext { defaultBuildToolsVersion="28.0.3" //String defaultMinSdkVersion=19 //Integer -…

You can use minSdkVersion as 21 as well, need not be 19 though.
