How to start preview automatically after first usb camera attached? There is no need to show dialog to select devices because I only need one camera plugged in. Help me, please!
hey, did you find any solution for this?
Yes, i have done it! I write this little function that open the first camera that he find. Add it into libusbcamera/com/serenegiant/usb/CameraDialog.java inside the CameraDialog Class. `
public Object getCamera()
{
updateDevices();
final List<DeviceFilter> filter = DeviceFilter.getDeviceFilters(getActivity(), R.xml.device_filter);
mDeviceListAdapter = new DeviceListAdapter(getActivity(), mUSBMonitor.getDeviceList(filter.get(0)));
Log.v(TAG,mDeviceListAdapter.getItem(0).getDeviceName());
this.dismiss();
return mDeviceListAdapter.getItem(0);
}
`
And then add these two lines into onCreateDialog function on the same file, before the return.
`
mUSBMonitor.requestPermission((UsbDevice) getCamera());
((CameraDialogParent)getActivity()).onDialogResult(false);`
It looks like this:
`
@Override
public Dialog onCreateDialog(final Bundle savedInstanceState) {
final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setView(initView());
builder.setTitle(R.string.select);
builder.setPositiveButton(android.R.string.ok, mOnDialogClickListener);
builder.setNegativeButton(android.R.string.cancel , mOnDialogClickListener);
builder.setNeutralButton(R.string.refresh, null);
final Dialog dialog = builder.create();
dialog.setCancelable(true);
dialog.setCanceledOnTouchOutside(true);
mUSBMonitor.requestPermission((UsbDevice) getCamera());
((CameraDialogParent)getActivity()).onDialogResult(false);
return dialog;
}`
Of course this is not the best solution but it's work!
@Guizzz it doesn't work
I honestly don't understand why the code section in my comment is badly indented and maybe you don't understand. I updated the comment and i tried to fix it. I'm sorry but I don't know how to help you more than that. Also i moved to another solution, this was just a work-around for me.
@Guizzz
i really need is when re enter to the activity it should connect camera automatically and show the preview . but when i re enter i get "conntecting" message from "onConnectDev(UsbDevice device, boolean isConnected)" but i dont get preview . so if i disconnect the camera and connect again it work
I really sorry but like i said i moved to another solution and this lib i don't neither remember how it is works
