Problems:

From AndroidManifest.xml on the Android app
<application
...
android:hardwareAccelerated="true"

<activity

</activity>
</application>

If you set it up and run it, it will slow down

Help me, please

Hello,

android:hardwareAccelerated="false"
rather than options
android:hardwareAccelerated="true"
It's slower when it's an option

How did it go?
