What steps can I follow to ensure my App is visible on my Android Device?

As a beginner using Ionic 3, I am trying to test my app on an Android device. However, when I enter the command

ionic cordova run android, I encounter an error and nothing shows up on my device.

Could someone please advise me on how to get my app to appear on my Android device? Any help would be greatly appreciated. Thank you.

Answer №1

The issue you're encountering arises from the presence of JavaVersion.VERSION_1_8 in your project without enabling Jack, which is necessary for supporting Java 8 language features.

As a matter of fact, jackOptions has been deprecated and must be handled differently. You can find more information about this here.

To resolve this issue, all you need to do is update your Gradle, Android Studio, and buildToolsVersion to their respective latest versions.

Answer №2

Try using "ionic cordova build android --debug" to test your application on your mobile device
