Hello guys. I’ve got a problem deploying my app to a device or an emulator. Every time i run the app on a device or an emulator with ionic run android it only shows a blank white screen. However, if I run it with ionic run android -l -c it will run just fine. I’ve seen many people having the same problems, but none of the suggested solutions worked for me.
Nvm, I found the problem, I had an extra slash before the template urls so the template files couldn’t be found. It should be “templates/something.html” not “/templates/something.html”
Why does a blank white screen sometimes appear when launching an Ionic app, and what are some practical steps developers can take to identify and fix the problem?
The cause of a blank screen in many cases is a JS error. Check DevTools and the logs in XCode/Android Studio to see if there are any errors.
I faced the same issue before. It usually happens because of small mistakes, like an extra slash in the template URLs, just like you found. Also, checking the browser console or device logs for any errors can help. Running the app with ionic run android -l -c is also a good way to find problems while debugging.
