Google Drive API - some helpful tips and code

I am not sure why, but there are not a lot of examples how to use Google Drive API from Android. If you're wondering about it, or you look for a working code, here it is... I assume you've already went successfully through the Google Drive SDK Quickstart -  https://developers.google.com/drive/quickstart-android  . 1) If you're using Eclipse as your IDE and you don't enjoy the command line, for step 1 in the Quickstart, you can find the right SHA1 fingerprint in Window->Preferences -> Android -> Build . 2) In Google Cloud Console (https://cloud.google.com/console) enable both Drive API and Drive SDK 3) Enabling Google Drive for your Activity. The code assumes that the main purpose of the activity is to synchronize your content (I called it BackupActivity - to backup all the content from the app to the Google Drive). a. In your Activity put the following: // change the following to your Activity name private final static String TAG = "Ba

How to make Logitech Trackball Marble Wheel work

If you bought Trackball Marble from Logitech, the first challenge you encounter is probably related to the lack of the wheel button. Unfortunately the software provided with the device for Windows doesn't help (neither Universal or Auto Search aren't really working as I was expecting). Internet suggests mostly one option, app called Marble Mouse Scroll Wheel http://marble-mouse-scroll-wheel.software.informer.com/ To some extent it works, but I wasn't able to make it work in google maps or in picture viewer. Moreover setting where crashing very often (I am running windows 7 64 bits). Fortunately there is a way to have a semi-wheel button behavior with this trackball, but with a different software - X-Mouse Button Control: http://www.highrez.co.uk/downloads/XMouseButtonControl.htm Setup Mouse button 4 and 5 as wheel up and wheel down. Then also update Logitech SetPoint settings to replace the behavior of those button to default. Voila - now you can emulate wheel

Android Notifications - lesson learned from implementation

Recently some Conf Call Dialer users asked to add notifications to the application, so (since it seems to be a good idea) I've spent few hours implementing them in the app. Everything went smoothly, except of one rather funny problem, after executing NotificationManager.notify, notifications were not showing up and I was getting all the time the following warning in the LogCat (12345 is the id assigned to the notification): notify: id corrupted: sent 12345, got back 0 My code seemed to be rather simple (mostly copy paste from the javadoc, with some app specific logic added): NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this). setContentTitle(event.subject).setContentText(event.timeFrom + " " + additionalText); // ... NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); mNotificationManager.notify(notificationId, mBuilder.build()); Googling didn't help, so I compare

Rendering AdMob view on Canvas (SurfaceView) in android

If you're wondering how put a working AdMob view into your SurfaceView and are tired of looking in the Internet for solution (somehow most suggestions that I found on forums didnt work), here it is... Assumptions: A. We request the ad on creation (you may want to refresh it later though...) B. The AdView is put on the bottom of the screen C. It's a production ready code, but if you want to test it - add testDevices to the adRequest D. You've already set AndroidManifest properly as described in the Getting Started tutorial 1. In the activity that initializes your SurfaceView add a field representing your adView, for example: private AdView adView; 2. In the onCreate method of the same activity put the following code: // window manager preparation WindowManager.LayoutParams windowParams = new WindowManager.LayoutParams(); windowParams.gravity = Gravity.BOTTOM; windowParams.x = 0; windowParams.y = 0; windowParams.height = WindowManager.Lay

ArrayAdapter notifyOnDataSetChanged doesn't refresh underlying ListView

If for any reason you're using ArrayAdapter to feed your ListView on Android you may be struggling with the fact that whatever you do - executing notifyOnDataSetChanged doesn't result in the corresponding ListView getting refreshed. There is one simple solution for this (and no, I am not talking about one that I saw on one forum where it was suggested to recreate the ArrayAdapter , which on a first glance may be a good idea at least until you're happy with the list jumping every time to the top). So what you need to do to have your ListView updated is: 1. Either execute  arrayAdapter.remove(itemToRemove); // if you want to delete item from the list or arrayAdapter.add(itemToAdd); // if you want to add an item to the list or 2. Execute arrayAdapter.clear(); // get rid of all elements arrayAdapter.addAdd(listOfItems); // add them back to the list Both work just fine.

How to join conference calls on Android

Since I am working for a global company for last few years, I spend quite a lot of time on conference calls. Still, joining conference calls especially if you're on a move isn't easy - I always had challenges when trying to memorize participant codes (again - especially while driving :)). But then - when you think about it, we have all the required information in the Android calendar, so it's only a matter of handling it properly. So here it is - Conference Call Dialer . I hope it will make your life easier (at least when it comes to joining conference calls :)) Additional information about the Conference Call Dialer : Functionality: - Retrieve information about meetings from the calendar - Dial into conference calls with conf code from the invitation - Manage and use multiple gateways (e.g. of your company and of your customers) - Review the invitations where conf code could be retrieved - A widgets for the home screen - Convenient "My conference call"
