Android Studio - Starts the app twice on USB_DEVICE_ATTACHED
I want to start my app on USB_DEVICE_ATTACHED action. It works fine but my app start twice. Is it possible to check if the USB_DEVICE_ATTACHED message comes twice (Maybe print the PID VID pair acording to the message?)
For test purpose I made a receiver and write all the PID VID pairs when it attached and that one comes once wich triggers my app to launch.
(I tried to start the app here in the receiver function but the main activity cannot reached the USB device (Maybe permission problem)
My hardware is an ODroid XU4 and has 3 USB devices (Touch Screen, Printer, POS terminal)
Here is my manifest:
<activity
android:name=".MainActivity"
android:launchMode="singleInstance">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<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/usb_device_filter" />
</activity>
And here is my usb_device_filter.xml:
<resources>
<usb-device vendor-id="4177" product-id="4096" />
</resources>
