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 : App Crashes - Can't Find A Java Method Despite - No Compiler Error
Aug 20, 2010My Android app runs fine, but: If I insert a call to WebView.setScrollbarFadingEnabled, it crashes saying:
Could not find method android.webkit.WebView.setScrollbarFadingEnabled, referenced from [my class]
VFY: unable to resolve virtual method 289: Landroid/webkit/WebView;.setScrollbarFadingEnabled (Z)V
I am using Android 1.5, not a custom ROM. My app defines minSdkVersion="3" I always clean before compiling.
Is setScrollbarFadingEnabled unavailable in Android 1.5? If so, why don't I receive a compiler error?

Android :: Java Compatibility With GetFields Method In Android Java.lang.Class
Feb 11, 2009I'm having some problems porting a Java application to work in Android platform. I detected an incompatibility problem between java sun and Adroid sdk in java.lang.Class. I oberved that: public Field[] getFields() Returns an array containing Field objects describing all fields which are defined. That's array is sorted as attributes are declared in the main Class in sun jdk. For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....

Android :: Android / Java - Call Function In Separate *.java File?
Aug 16, 2010I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.
For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}
9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!

Android :: ApplicationContext.java And Activity.java - Is ApplicationContext Not Used
Sep 29, 2009I was going through the code for Activity.java and ApplicationContext.
Both these classes define many functions of Context Interface. Take for example startActivity.java
Activity Class has its own implementation of startActivity ApplicationContext class also has an implemenetaion of startActivity.
Now there are 2 observations...
CODE:..........
Questions: 1. Who uses ApplicationContext class? 2. Does Activity class ever deal with ApplicationContext class (as given in the javadoc comments of ApplicationContext.java).

View 1 Replies View RelatedAndroid :: Java To C++ Bridge
Sep 18, 2010I know there are plenty of tutorials about integrating C++ into Java, but whats about the other way around, a Bridge from Java to C++?
The reason i'm asking this is Android.
Every C++ developer who wanted to write applications for the android noticed at some point that there is no serious (mature) C++ api for android (infact, android is lacking an implementation of the STL).
The only API that is mature enough to write android applications in, is Java. So instead of writing an api from scratch, wouldn't it be possible to use the Java Classes from C++?
I know that this sounds merely like an unrealistic dream, but that way most C++ developers weren't forced to learn a new Language.

I need to get a couple of values out of the XML and the structure isn't that deep. [3 levels]

View 1 Replies View RelatedAndroid :: Way To Use Java RMI Api In Phone App?
Nov 5, 2010We are implementing a sever-client architecture and some of the client apps are supposed to run on android OS. The first idea that came to mind was to use Java RMI, but the RMI api is obviously not implemented for android.So
1) Is there a way to use the Java RMI api in an android application? Can I just import it from the standard java library?
2) What are the possible substitutes for RMI which will work for both android and desktop applications?
Android :: Java API For OpenGL ES 2.0?
Aug 25, 2010I am learning Android development, specifically to eventually do OpengL 2.0 ES on it. So far I have read that the NDK supports Opengl 2.0 ES. However, is there also a Java API for it? If there is a Java API for it, which one is recommended? I know both C++ and Java, so it is not a big deal if I have to use the NDK, but I would prefer to work only in Java if possible and without a big performance hit.
View 1 Replies View RelatedAndroid :: R.java Is Not Being Generated
Jul 23, 2009I've been working on a project for several weeks now, and just tonight I started having a problem. The R.java file is no longer being generated. I've attempted to clean the project (the first time I do this it removes the R.java file but doesn't regenerate it) and have tried uninstalling and reinstalling the SDK. I've also tried resetting adb to no avail.
This problem does not occur in my other Android projects. They clean just fine and regenerate the R.java file like nothing is wrong. This particular project is the only one suffering from this problem.
Android :: Java Self Naming?

Could I then create a variable named scruffy from that variable. In PHP it would be $$dog. That would make a variable with the name scruffy.
View 1 Replies View RelatedAndroid :: Modifying The UI Within Java - Not XML
Jul 11, 2009So I have the basics down... I can create a UI with the XML, I can show it and change the screen to another UI (another XML file) but how do I add to the UI?
Hard to explain...
Say I have a header (just 2 textviews) that will remain at the top and below that is a search box and button (main.xml). The user searches and I have it display the search UI (search.xml). This UI will have the same header (2 textviews) and below it will have several textviews each one containing a search result... Kinda like if you search for an app in the market. There's no way of telling how many results would be returned so I figured I would have to create each textview on the fly within the .java file. I'm not sure how to do this. Most likely would require a loop of some sort, but whats the syntax to create a new textview and display it right below the one above it? I'm working with linear here so I would assume just creating a new textview it will by default go to the next one down which is what I want.
Also, say I have 30 results... How do I get those to scroll but leave the 2 textview header in place? Would I create a ScrollView and put the new TextViews in that?
Android :: Alternatives To Java?
May 14, 2010However I'm not a big java fan, although I can live with that, I would like to know if there're reasonable alternatives for the android virtual machine. I've done a medium sized project using clojure, however from the reviews I read, it's very slow when running on android. How about scala ? I read that some people did experiments with it in android, is it "fast enough" ? How big is the learning curve ?

Android :: How To Get TTL Of UDP Packet In Java
Nov 24, 2010I am using a Java application to send UDP packets to an Android device. There I have another Java application that receives these UDP packets and displays its data - very simple.Now I am working on some routing algorithms - therefore it would be nice to know how many hops a UDP packet did since it was send. My idea is to just read out the TTL (time-to-live) value of the packet and display it. Do you know if this is possible with pure Java? The class DatagramPacket doesn't give any hints at all.I guess that this is not possible because this information might already have been removed at a lower layer, but I just want to be sure. :-)
