Is there a way to detect when a USB flash drive is plugged into an Android device? I'm able to detect an SD card using a broadcast receiver, but it doesn't work for USB. I'd like to avoid polling.
code to register receiver:
private void RegisterUpdateReceiver()
{
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction("android.intent.action.MEDIA_MOUNTED");
intentFilter.addDataScheme("file");
myReceiver = new MyReceiver();
this.registerReceiver(myReceiver, intentFilter);
}
receiver code:
public class MyReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
String action = intent.getAction();
if (action.equals("android.intent.action.MEDIA_MOUNTED"))
{
// react to event
}
}
Android, at the SDK level, has no concept of USB drives. There are no rules for where they should be mounted, broadcasts for when they appear/disappear, etc. Perhaps some standardization in this area will come in future Android releases, but it is not there today.
