unity3d - Android UsbHost Problems with Samsung Galaxy Tab S 10.5 and Unity -
when application opened, , usbdevice attached, application able communicate device, , doesnt. error's receive differ every time. constant is, works expected on samsung galaxy phone, nexus 7, nexus 10. if application launches device beingness connected, works expected, of time.
manifest set so
<uses-feature android:name="android.hardware.usb.host" /> <uses-feature android:name="android.hardware.usb.usbinterface" /> <activity android:label="@string/app_name" android:screenorientation="fullsensor" android:launchmode="singletask" android:configchanges="mcc|mnc|locale|touchscreen|keyboard|keyboardhidden|navigation|orientation|screenlayout|uimode|screensize|smallestscreensize|fontscale" android:name="com.realart.beatmaker.unityplayernativeactivity"> <intent-filter > <action android:name="android.intent.action.main" /> <category android:name="android.intent.category.launcher" /> </intent-filter> <intent-filter > <action android:name="android.hardware.usb.action.usb_device_attached" /> </intent-filter> <!-- usb connect list --> <meta-data android:name="android.hardware.usb.action.usb_device_attached" android:resource="@xml/device_filter" /> <intent-filter> <action android:name="android.intent.action.view" /> <category android:name="android.intent.category.default" /> <category android:name="android.intent.category.browsable" /> </intent-filter> <meta-data android:name="unityplayer.unityactivity" android:value="true" /> <meta-data android:name="unityplayer.forwardnativeeventstodalvik" android:value="false" /> </activity> in oncreate, check see if application launched intent, by:
// device woke activity usbdevice connecteddevice = (usbdevice)getintent() .getparcelableextra(usbmanager.extra_device); if (connecteddevice != null) { usbmanager manager = (usbmanager)getsystemservice(context.usb_service); usbdevice device = connecteddevice; writedeviceinfo(device); initdatatransferthread(manager, device); } if application opened, , because launchmode singletask, i've overridden onnewintent method so
@override public void onnewintent(intent intent) { final string device_connected = "android.hardware.usb.action.usb_device_attached"; string action = intent.getaction(); if (action.equals(device_connected)) { log.d(tag, "device connected"); final usbmanager manager = (usbmanager)getsystemservice(context.usb_service); seek { final usbdevice connecteddevice = (usbdevice)intent .getparcelableextra(usbmanager.extra_device); if (intent.getbooleanextra(usbmanager.extra_permission_granted, false)) { if (connecteddevice != null) { writedeviceinfo(connecteddevice); initdatatransferthread(manager, connecteddevice); } else { log.d(tag, "device null"); } } else { log.d(tag, "permission denied"); log.d(tag, "asking permission , trying again..."); manager.requestpermission(connecteddevice, permissionintent); } } grab (exception e) { log.d(tag, "exception throw: " + e.tostring()); e.printstacktrace(); } } } and hits permission denied else block in method, goes permission check broadcast receiver have set so:
// attach events attachreceiver = new broadcastreceiver() { @override public void onreceive(context context, intent intent) { log.d(tag, "permissions receiver hit"); string action = intent.getaction(); log.d(tag, "action requested: " + action); usbmanager manager = (usbmanager)getsystemservice(context.usb_service); if (intent.getaction().equals("com.realart.beatmaker.usb_permission")) { // thread still running? if (arduino != null) { if (arduino.pipeline != null) { message msg = message.obtain(); msg.what = change.usb_disconnected; arduino.pipeline.sendmessage(msg); } arduino = null; } synchronized (this) { log.d(tag, "checking permissions user..."); usbdevice device = (usbdevice)intent.getparcelableextra(usbmanager.extra_device); boolean permissiongranted = intent.getbooleanextra(usbmanager.extra_permission_granted, false); log.d(tag, "permissions granted: " + permissiongranted); if (permissiongranted) { if (device != null) { writedeviceinfo(device); initdatatransferthread(manager, device); } else { log.d(tag, "device null"); } } else { log.d(tag, "permission denied user"); } } } } }; permissionintent = pendingintent.getbroadcast(this, 0, new intent("com.realart.beatmaker.usb_permission"), 0); intentfilter attachfilter = new intentfilter("com.realart.beatmaker.usb_permission"); registerreceiver(attachreceiver, attachfilter); that process doesn't seem causing errors, , device info writes out every time. sometimes, lists 2 interfaces, 0. weird, , dunno why that.
this how initializing device:
private boolean initserialbus() { seek { // open device connection = usbmanager.opendevice(arduino); if (connection == null) { log.d(tag, "opening device failed"); homecoming false; } // serial interface usbinterface = arduino.getinterface(1); boolean interfaceclaimed = connection.claiminterface(usbinterface, force_claim); log.d(tag, "usb interface claimed: " + interfaceclaimed); if (!interfaceclaimed) { log.d(tag, "trying 1 time again kernel driver"); interfaceclaimed = connection.claiminterface(usbinterface, false); if (!interfaceclaimed) { log.d(tag, "unable claim interface."); homecoming false; } } // arduino usb serial converter setup log.d(tag, "data transfter setup"); // line state int linestate = connection.controltransfer(0x21, 0x22, 0, 0, null, 0, 0); if (linestate < 0) { log.d(tag, "line state command transfer failed."); log.d(tag, "return value: " + linestate); releaseusbresources(); arduinostate.onarduinoerror(new exception("control frame transfer error")); homecoming false; } log.d(tag, "line state command frame: ok return: " + linestate); // line encoding (9600 baud) final byte[] lineencoding = { (byte) 0x80, 0x25, 0x00, 0x00, 0x00, 0x00, 0x08 }; int lineencode = connection.controltransfer(0x21, 0x20, 0, 0, lineencoding, 7, 0); if (lineencode < 0) { log.d(tag, "line encoding command transfer failed."); log.d(tag, "return value: " + lineencode); releaseusbresources(); arduinostate.onarduinoerror(new exception("control frame transfer error")); homecoming false; } log.d(tag, "line encoding command frame: ok return: " + lineencode); // i/o endpoints (int = 0; < usbinterface.getendpointcount(); i++) { usbendpoint endpoint = usbinterface.getendpoint(i); if (endpoint.gettype() == usbconstants.usb_endpoint_xfer_bulk) { if (endpoint.getdirection() == usbconstants.usb_dir_in) { arduinoin = usbinterface.getendpoint(i); } else { arduinoout = usbinterface.getendpoint(i); } } } // ensure found endpoints if (arduinoin == null || arduinoout == null) { releaseusbresources(); arduinostate.onarduinoerror(new exception("no usb endpoints found")); homecoming false; } log.d(tag, "i/o enpoints found"); arduinoconnected = true; } grab (exception e) { e.printstacktrace(); } homecoming arduinoconnected; } this usual logcat output:

when application launched, logcat output looks this:

does have thought why behavior unusual tablet?
model: sm-t800
android version: 4.4.2
kernel version: 3.4.39-2010469
build number: kot49h.t800xxu1anfb
in case hits same problem, main section of app created unity , race status between spawned thread reacted intent, , unity on grabbing usbinterface. on boot, because unity wasn't initialized yet, spawned thread able capture interface 99% of time, after unity spawned up, untiy through jni able claim interface first. i'm not exclusively sure why claiming sensor on tablet, , not other ones, has exynos 5 octa 5420 chipset , how unity decides sensor.
