Android :: Eclipse - When Building An App - Deleted The "R" Class And Cannot Get To Generate It Again

Jun 10, 2010

Basically I've been playing around with developing Android apps and I was editing one earlier. I changed my main.xml file and when I went back to my class that runs the app all references to the "R" class were broken. I looked in the "gen" folder (Generated Java Files) and saw that the class was completely gone from the solution.

I had been debugging not 5 minutes before and didn't have any problems doing so. The only things I had done since debugging were moving 2 files from the "drawable-hdpi" folder to the assets folder and I had edited the "main.xml" file.

I've tried cleaning the project and restarting Eclipse but neither of those ideas worked.

Android :: Generate Java Source Code In Eclipse?

Jun 2, 2010

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

Android :: Way To Generate Binaries With Different Configuration Settings In Eclipse

Aug 5, 2009

This is more of Eclipse related to question, but taking chances as someone might faced this issue for android development.

For my android application I want to generate multiple binaries from common source code and resources. Also looking out for way for doing preprocessing of Java source code. This is something which is very much straight forward in Netbeans using Project configuration. Is there any equivalent way available in Eclipse to achieve this ? Are there any plugins for such things?

Android :: Eclipse To Compile Files - Test - Src Instead Of - Src - Directory When Building

Nov 18, 2010

Can an android project in Eclipse be configured so that the built-in builders read from an alternative source directory? ie. "test/src" instead of "src"? and possibly even "test/res" instead of "res"? (It appears that setting dirs in the property files will only affect ant and not the built-in builders)

Android :: Eclipse Project - No Class Files Specified

Feb 19, 2009

I've noticed that then I use "clean" from Eclipse project menu on my project I receive following error

Project doesn't use any external jars and rather simple. If I uncheck build automatically and build it - it builds and runs just fine. I'm on MacOSX 10.5.6 and JDK 1.6.0_07. And latest android SDK ( android-sdk-mac_x86-1.1_r1.zip 79046151 bytes becf0f1763d61eedce15d2a903d6c1dd )

Android :: Eclipse Class File Metadata

Jun 7, 2010

In Visual Studio, I can obtain a succinct list of public methods/members exposed in a class for which I do not have the source (i.e. bundled inside a DLL) by pressing F12 (GoToDefinition).

Similarly, I am learning the Android API - in Eclipse. Jumping to an Android framework method definition produces decompilation output which is not intuitive to read, and is very verbose. To mimic results like Visual Studio, I am considering several options:

How can I format the decompilation output to be 'cleaner' - I have looked through Eclipse's preferences menus and have not found a way to do this.

How do I 'add corresponding source files' once Google provides it, so that jumping to definition yields the actual definition?

Is there a plugin that does this already? I looked into Jadclipse, but that project has not been updated in several years, and is still a decompiler.

Android :: Added Library Project And Now Eclipse Can't Find R Class

Jun 26, 2010

I am trying to add an 'Android Library project' I have created to another regular Android project. The Library Project had a jar dependency and was also dependent on another java project in my workspace. I had to add both of these to the my 'regular Android project' because otherwise Eclipse could not find them (Not sure if this was the right thing to do because it would mean that I will have to manually update all projects when the library gets another jar dependency). Anyway, the errors went away and now the Regular Android Project can't find the R class, I have tried a clean but it did not work. I checked in the /gen folder and both the R classes are there - from the library and the regular project.They have the correct strings inside them.

Android :: Eclipse Doesn't Recocnize ImageView / Need To Create Another Class For It?

When I type ImageView or AnimationDrawable I get a string of errors proclaiming:

AnimationDrawable cannot be resolved to a type.

line 14 Java Problem

I don't understand, do I need to create another class? Or do the AnimationDrawables just not go in the filename.java?

And if I do need to create another class, can you show me how?

Android :: Android Eclipse Class Path

Jul 7, 2009

I'm using Eclipse to learn to develop Android applications in Java. I haven't used Eclipse before.The project I'm trying to use (supplied by OReilly as part of 'Android Application Development') is MJAndroid. When attempting to run the project, the Run fails, and the Problems tab mentions com.java.Object can't be found, and Eclipse asks me to check the build path. Clicking Properties -> Java Build Path -> Libraries, the message 'Unable to get system library for the project' is displayed.On a working project, Properties -> Java Build Path -> Libraries has an entry for Android 1.1, which if I click Edit, has the classpath container path of com.android.ide.eclipse.adt.ANDROID_FRAMEWORK.It seems a simple matter of adding the correct container path to my non-working project. However Eclipse seems determined to make this as difficult as possible. No matter what I chose to add - jars, externals jars, variables, libraries, class folders, external class folders, nothing seems to take the form of 'com.android.ide.eclipse.adt.ANDROID_FRAMEWORK' that the 'Android 1.1' entry on the working app has.

Android :: Communicating Between Receiver Class And An Activity Class

Jul 14, 2010

I'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.

str = s;

Android :: In Java, What Does A Reference To Class.class Do?

Jul 20, 2010

I'm building a small Android application, but this is more of a Java question than an android question. Looking through the tutorials there are lines that look like: startService(new Intent(this, MyService.class));

What exactly does the "MyService.class" field represent? Is that just a reference to the class for a template?
