Android :: Java Unable To Find Class At Runtime From JAR I Created
Nov 19, 2010I am working through a facebook-sdk example and trying to utilize the collection of classes as provided as a .JAR. I am relatively new to java and eclipse so I expect I am making some obvious blunder.
The issue is that everything seems to compile fine, but when I run the project (using the android emulator) dalvik vm is unable to find the first class I reference from this facebook sdk. ( com/facebook/android/Facebook.class )
As an aside, if I copy the source directly into my project as an additional package everything works fine.
Step 1: I exported the com_facebook_android project as a .JAR file. ( right click project, export, java / jar file ) I choose c:datajagjar as my location to save facebooksdk.jar.
Step 2: I hit properties on the project HelloGoogleMaps, Selected Java Build Path, Libraries, Add External JARS... I the directly selected the c:datajagjarfacebooksdk.jar file.
At this point my project seems to be building just fine ( no errors ).
Step 3: Debug the project and receive the error:

Android :: Runtime Error Using Exported - Signed Apk But No Runtime Error Using Eclipse IDE
Mar 2, 20091) I am developing my app in Eclipse 3.4.1 with Android (ver 1.1_r1) plugin. My app compiles and executes without errors when using the Eclipse IDE.
However, when I export my app (unsigned) using Eclipse (via {select project} >right-click>Android tools>export unsigned application package), sign it, and try to run it on the Emulator, it throws a runtime error when I try to update my sqlite database, at which time the specific error created is: SQLite error#14, unable to open database. It is able to read from the database without problems. (I have also verified that the database is: open, is not readonly, is not locked by another thread, is not in the middle of a transaction.)
I have limited experience, but this seems more like a "system" problem given that the app works OK in Eclipse IDE but then fails as an exported/signed apk. Some googling of SQLite resources revealed a similar error on a non-Android platform which was fixed by: "Set your permissions correctly on /var/tmp, or whatever directory you are using to hold temporary files".
Does Android have temporary files, and if so how does it handle permissions on temporary files? Is there a way to check or set these permissions to see if this fixes my problem here?
2) Not sure if it is related, but after I have run the exported/signed app which causes the runtime error, if I reboot the Emulator, and try to run the program using the Eclipse IDE , the program fails with the same exact error. PLUS I also noticed the following error message while the program is installing/running: 03-01 22:22:29.282: ERROR/PackageManager(53): Package com.northwestradiology has mismatched uid: 0 on disk, 10019 in settings; read messages:
I can restore the Eclipse version of my program to be able to execute without runtime errors by utilizing the -wipe-data option for the emulator. But note that if I run my signed APK using an emulator created with the -wipe-data option, it still throws the runtime error listed above...

View 2 Replies View RelatedAndroid :: Copy All Properties Of A View?
Aug 19, 2010I'm creating an currency exchange rate application to learn Android. The app will list all exchange rate in a list, each of them has the layout like this (in essential) code...
To list exchange rate for all currencies I have the following approach:
- Design the layout for one currency (let's choose EUR as first currency)
- Generate the layout for all other currencies automatically by:
1. Copy all properties of the EUR-layout into the new currency layout
2. Modify some properties of new currency layout like: ID, Rates ...
3. Repeat steps 1,2 for all sub-layout of the new currency layout
But I don't know how to code step 1, so I did a lot of google about: "android copy view" "android copy properties" "android copy view" "android clone view" "java clone object" .... but still no solution.
So, my question is: how to copy all properties of a view ?

May 20, 2010I have an activity with a ListView which is populated through a custom ArrayAdapter. There is an array of objects which have a Boolean property called 'isRead'. Based on the value of this property, I want to set the typeface of one of the TextViews in the row to either 'normal' or 'bold'. I also set the color of the text to either 'gray' or 'black When the Activity initially starts up, everything works as expected. If isRead is true, the text is gray with a normal font.

View 1 Replies View RelatedAndroid :: Seeing Double ListView To Change Properties
Apr 25, 2009I am wondering if anyone else is encountering this issue (or if its just me). I converted an app I have been working on from using a regular view to using SurfaceView. The app accesses listviews to change properties of the elements I am drawing on a canvas. The listviews called from the SurfaceView version draw over themselves mis-registered when I scroll long lists quickly. If anyone out there has had a similar problem and/or has an idea what might be going on and/or has a suggestion as to how to fix this.

Android :: User Defined Application Properties?

Android :: Creating Custom Widgets / Defining Properties In XML For Them
Jul 29, 2009I would like to create a widget that can reads its attributes from an XML file onCreate. I've created a Custom Button that extends Button widget. I would like to define its layout and styling in an XML, such that the widget can be reused across different views, with the same styling attributes. The notepad sample code does carry some pointers to this problem, however, it defines a XML layout with the component as View, inside LinearLayout, which is not really what I'm trying to achieve here.
