Progress on Offline Logger 0.3
Posted by Erik Karlsson in Android, Offline Logger on May 21st, 2010
Hi everyone, I just wanted to let you know that I’m actually working pretty hard on getting the 0.3 version ready as soon as possible. It’s about to become a really major update so I really want to test things through before releasing the update. It has lots of new nice features and UI improvements.
It has a few more goodies except the previous published feature list, but they will remain a secret for now 
I can just assure you that this app will soon become your favourite logger !

Offline Logger v0.2 + some battery stats
Posted by Erik Karlsson in Android, Offline Logger on May 14th, 2010
A bug was found. An embarassing one, but now it’s fixed and a new update is available on market!
The bug caused the history log-files not to be saved, which made the applications main-task to fail, but the fix was easy and now it’s working again. The reason was that the application tries to access the memory card to verify that it’s available and writable before starting a log (so you don’t log for 5 hours and then not possible to store the coordinates), but it created a file with the same name as the directory it tries to save the log-files to later, which made the directory creation to fail. A file and a directory with the same name cannot exist in the filesystem.
Many excuses to the affected people (probably <5 people since the application is new )
Battery statistics
I’ve been testing the application with 5seconds interval on a fully charged HTC Hero running Android 1.5. The results were pretty impressive, allthough I was running without a SIM-card and with wifi off (like airplane mode). It ran for about 12 hours, and then I turned it off manually, but it will run for an estimated 15 hours @ 5sec interval before battery is fully drained.

How to create your own “Share” application for photos
Posted by Erik Karlsson in Android on February 12th, 2010
This is alot easier to do than you might believe, it’s even so easy to do, that you might find it hard to find information about it in the documentation.
The main thing you have to do is to register your application to receive the SEND intent which is sent when clicking the “Share” button.
Add this to your Activity in the AndroidManifest.xml
<intent-filter> <action android:name="android.intent.action.SEND" /> <data android:mimeType="image/*" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter>
Then you automatically get your application registered to the Sharing-list with the application name and icon, when selecting the application in the list, the activity will be launched and the photo is easily retreived through the launching intent.
final Intent intent = getIntent(); final Bundle content = intent.getExtras(); if ( content != null ) { //The uri below till contain an uri to the contentprovider final Uri uri = (Uri)content.getParcelable(Intent.EXTRA_STREAM); //if you want to know the filename of the image, just do a managedQuery //against the projection MediaStore.Images.Media.DATA }
How to pull and install the dev-apps to your Android device
Posted by Erik Karlsson in Android on February 12th, 2010
The emulator and some Android developer devices have some small util applications which could be to some help if you’re developing an application for an Android device. Looking at your production phone will reveal that you don’t have those pre-installed, but it’s easy to get them from an emulator and then install them to your real phone.
These apps will let you change and/or simulate a non-existing locale, view stacktraces from log-files, more detailed information about battery-usage, and so on…
Start by navigating to the tools directory within your Android SDK, then execute the following commands after you’ve started your emulator:
adb -e pull /system/app/CustomLocale.apk CustomLocale.apk adb -e pull /system/app/Development.apk Development.apk adb -e pull /system/app/SpareParts.apk SpareParts.apk
That will retreive the packages for the three applications CustomLocale, DevTools and SpareParts from the connected emulator.
Then connect your device with the USB-cable if it’s not already plugged in and execute these commands from the same location:
adb -d install CustomLocale.apk adb -d install Development.apk adb -d install SpareParts.apk
Then you’ll have the three utils installed to your phone, ready to use.
Please note that everything might not work if you don’t have a real developer device, or running on a non-rooted device, some features might crash while trying to use them.
