FAQ

What files should be deployed to Android device?
Add these files in Delphi Deployment window:

Local Name	Remote Path	Note
pl2303driver.dex	assets\internal\	Delphi 10 and higher: add pl2303driver.jar to Libraries list in Project Manager instead
device_filter.xml	res\xml\

Add these lines to AndroidManifest.template.xml file:

<intent-filter>
  <action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
</intent-filter>

<meta-data android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" android:resource="@xml/device_filter" />

How can I determine chip used in USB/RS232 adapter?
Use HWiNFO on PC and USB Library for Android demo example on Android.
