Ionic 3 Android Application Start Delay

I had developed application for my Android, with the following Ionic configuration, @Ionic\App script : 3.1.10 Cordova Platforms : Android 6.3.0 Ionic Framework : Ionic Angular 3.9

Solution 1:

I had the same issue, researching a lot of it, the solution I found was to just add more time to the splash screen. This delay is due to the connection between the native modules and web modules.

Those are the disadvantage working with hybrid apps. Also you can check if the Ionic 4 upgrade solved this issue and upgrade yours.

Solution 2:

run --list --prod does not generate the "final" version in apk. To get the delay you need to generate the "final" version with zipalign. Remember that before it is necessary to generate the key with the jarsigner -verbose
