Blank Black Screen When Launching Ionic App on Android

Hi everyone,

Blank Black screen appears every time I launch my Ionic app on an Android device. The app builds and installs successfully without any errors, but when I open it, the screen stays completely black, and nothing loads. I have already tried updating Ionic, Capacitor, and all plugins to the latest versions.

I also double-checked the AndroidManifest.xml and build.gradle files for any misconfigurations and verified that all assets are included with correct paths. Despite testing on multiple Android devices, the issue persists. Iam using Ionic Angular with Capacitor, targeting Android 11.

Has anyone experienced this problem before or know how to resolve it? Any suggestions please share with me, thank you.

A blank screen usually points to a JS error. Check DevTools by running the app through Android Studio in an emulator or physical device and go to chrome://inspect/#devices on your computer.
