Android :: Eclipse Reading Code As Java
Nov 23, 2010
I just inherited a project at my workplace and I am having trouble having Eclipse act as an Adroid editor rather than a Java editor. Pretty much everything is under lined and I can't seem to find a way to change how it is interpreted. I have downloaded all of the Android SDK's and the Eclipse Plugin. I can create Android projects and write the code just fine, but everything is still underlining. I must be missing something simple. Any suggestions, something I missed or didn't download?

Did anyone create the Java Code Formatter Profile for Eclipse IDE that conforms to the Android Code Style Rules? Android Code Style Guide defines "Android Code Style Rules".To conform to these rules one have to change quite a number of settings of the Java Code Formatter
(Window->Preferences->Java->Code Style->Formatter) default profile (in Eclipse IDE).
Did anyone manage to configure the formatter to follow the "Android Code Style Rules" already?
If yes, please export the Formatter profile and publish to be used by community. I've tried to do this myself but I've found that there are too many formatter options available, and most of them are not mentioned in the Code Style Guide.

Does anyone know what approach one can take to automatically generate Java source code, from for example an xml or json file, in eclipse? One great example of what I am thinking of doing is what Google Android sdk does: they have an R class generated automatically from the resources. Every time a resource file is saved in Eclipse R class is automatically regenerated.
UPDATE: Example:
In the text (xml or json file) I have the following:
<tags>
<tag id="ALPHA">
<description>The first alpha tag.</description>
<value>231232</value> </tag> <tag id="BETA">
<description>This is the beta tag.</description>
<value>231232</value> </tag>
Then in my generated java class, say R I would have something like:
R.tags.ids.ALPHA //refers to an enum value for example
R.tags.values.ALPHA //refers to final int with avlue 231232
R.tags.descriptions.ALPHA //refers to the String with description

Now I know android works closely with java programming, so android is based off of java.In my application, I want a spinner, with 8 choices, and when the "spin" button is pushed, I want the spinner to randomly choose one option.
Can I create the spinner entirely with java code outside of android and then just insert the code into the .java file in eclipse? I'm familiar with java and would be able to pull this off if you can do it this way.

I'm writing an Android application. One problem is your app cannot contain a file whose uncompressed size is bigger than about 1Mb. I have a serialized object that I want to load that totals about 2Mb. My plan was to split this file into two smaller files, then load the object by combining both files at runtime.
However, I cannot work out how to use e.g. InputStream and ObjectInputStream to specify that I want to read the data from two input streams. How can I do this?
For example, say my object was split between file O1 and O2. How can I say "Load the object by reading the data from O1 then from O2"?

I am currently working on a group project to build an Android game. I have been delegated the task of building a PC based level editor (which is all done). All I have to do now is decide on the file format for the map that is outputted. At the moment it is just a standard text file with different numbers to represent different tiles; E.G 0=path 1=wall 2=enemy.
1 1 1 1 1 1 1 1
1 0 0 0 2 0 0 1
1 1 1 1 1 1 1 1
The actual Android game then takes this file and stores the values into a 2D Array. However those who are making the actual game are having difficulty opening a text file, and others have told me it has to be done using an XML file. I have now been asked to find a away to take in this input. how I would read the text file and put the values into a int array[][] ? Or if it is easier, use an XML file and tell me how to format that file and read the values into a int array[][]

System config is MacOSX with default JDK 1.5.0_16. Eclipse 3.4 The problem is I have a project in workspace that has been developed under JDK 1.6.I don't really want to switch back to 1.5 ( i' would have to clean up a LOT of @Override ) but if i work with this project, after couple of rebuilds - eclipse layout editor not able to display preview. Work around i found so far open android project that is in compliance with Java 1.5. Close everything else and rebuild workspace. But it's kind of annoying to do it every time.

The following link states that "A Java or RCP version of Eclipse is recommended. For Eclipse 3.5, the "Eclipse Classic" version is recommended."
http://developer.android.com/sdk/installing.html
However, Eclipse 3.6 is available and as a total newbie I am not sure whether the recommendation for "Eclipse Classic" over RCP (or Java) still holds true.

I've got Eclipse setup for Android/Java development and it seems to be working.
How do I add PHP development as well to the Eclipse installation?
Must I install Eclipse on a separate PC in order to do PHP dev ?
If I can add PHP to the Eclipse setup for Android/Java... where do I click to do it?

I checked out cupcake branch yesterday and made the full build and sdk successfully, and I also built the ADT 0.9 with the command cupcake/development/tools/eclipse/scripts /build_ server.sh on another Linux box. Then I updated the ADT 0.9 and set new SDK on Eclipse. Then I created a simple Android project Test with Android Project Wizard, the Eclipse created project files except the R.java and then reported following errors. Seems the resources are not correctly parsed. Errors: [2009-01-21 15:07:32 - Test] W/ResourceType( 267): Unable to get buffer of resource asset file [2009-01-21 15:07:32 - Test]

I'm trying to use the Amazon Web Services Java SDK jar in an Android project in Eclipse, but it has references to org.apache.commons.httpclient. All I seem to have in my Android SDK (2.2) is org.apache.commons.http.client, which is a different namespace and obviously causes the build to fail.
I'm new to Java, Eclipse, and Android dev... is there a way to "map" one name space to the other or create some sort of symbolic link? If not, does that mean I have to import a "standard" org.apache.commons library?

Is there a (simple) way to completely and utterly disable all Java formatting in the Eclipse editor?
That is an Eclipse question, but I appreciate your indulgence because this problem is slowly driving me insane. I am spending a lot of time fixing code to make it look good again after it gets mangled by the automatic formatting. I thought I had removed all formatting keyboard shortcuts, but I missed something because my code keeps getting changed. I suspect the culprit to be the SourceFormat menu option because that can be triggered by Alt-S-F which is very close to Alt-F- S, the File/Save command.
So a little finger slip and code mangled. Unfortunately, the mangling is not always done where I am looking (since it is applied to the entire file), so I don't always know to undo it. Is it possible to disable or remove a menu item?

I'm working on two projects. One is essentially a library, and the other is an application using that library. Now from the application project, I want to use the library's classes, so I added that project to the "required projects" under java build path. It seems to compile fine, but at runtime, I get this error:
07-27 11:26:57.037: ERROR/dalvikvm(741): Could not find class 'interdroid.contextframework.ContextManager', referenced from method com.bartvanwissen.contextframeworktest.MainActivity.onCreate
Apparently, the library project's classes are not added to the apk file. How can I make sure they are included? Since I'm working on both projects at the same time, I would like to prevent having to create a jar file every time I want to test something.

I have an interesting problem. I pull down an android project from cvs, which works fine. Once Eclipse builds the project, my .java files are removed. XML files, pngs, everything else is fine. I seem to be left with just the package tree, but no source files. Any thoughts?

I've seen a few places where this was asked but I haven't seen where it's been resolved. I've just installed the tools needed to develop Android applications. This includes, of course, Eclipse. When I try to open the res/main.xml file, I get the error 'could not initialize class java.awt.font'.I'm running the newest version of Eclipse and all the software required for Android development. I'm running on Ubuntu 10.04 32bit. Sun JDK and JRE are installed.
