Android :: Eclipse Code Assist - Speedup
Oct 16, 2010
If you are using the JEE edition of HELIOS (3.6), the assists can be speeded up by turning off JAX-WS assist in the edit/advanced preference (Window->Preferences->Java->Editor->Content Assist->Advanced. It also appears that the assists cycle through a list of suggestion sources, starting with a different one each time, which would explain why the assists are not always slow.

When I use Eclipse first time I can use it. But suddenly it doesn't support assist code. I think I did set up anything. Usually when I coding Java code. But XML is okay.

I just switched from Ubuntu 8.10 to Ubuntu 9.04 and noticed that Eclipse Content Assist isn't working anymore. I tried the following variations on Ubuntu 9.04: Eclipse 3.4.2 or 3.5 (cleaned / reinstalled) with ADT 0.93 and Android SDK 1.5r3 Using Sun Java 1.6. No combination works. I've reinstalled everything a bunch of times. I have another machine with Ubuntu 8.10 and Eclipse 3.4.2 with ADT 0.91 or 0.93 and Code Assist works for all those. I just refuse to develop without code-assist and I know lot of people would agree with me on that.

I've been working in Eclipse programming for Android for about a year now. I suddenly have an enormous problem. Here is the error: "Content Assist" did not complete normally. Please see the log for more information. java.lang.NullPointerException
I go to Help>About Eclipse SDK>Installation Details>Configuration>View Error Log and it is nothing but a blank page. No errors at all. I tried researching online. The most relevant pages I could find are
http://forums.adobe.com/thread/455543 and
http://www.themorphicgroup.com/blog/2009/10/27/content-assist-did-not-complete-normally/ and
http://www.airtightinteractive.com/2010/01/fix-for-flash-builder-content-assist-did-not-complete-normally/
All of these pages say to close FB, delete the .metadata folder, restart FB, import/export some SWC file, and/or delete some file with "flexbuilder" in it's name. None of these work and I see nothing on my whole machine with any of "Flash Builder", "FB", "flex", or "flexbuilder" in it's name. As a desperate last resort I deleted all traces of Eclipse, Android, Adobe anything, and Java from my machine. Absolutely no difference what-so-ever. Besides exhaustion and heartache for me. The content assist features seem to work fine in java files (for now anyway). It seems that only .xml files are affected.

I'm not sure is this is a problem with my installation of Eclipse (Helios) and Android SDK or something else but Eclipse Content Assist doesn't propose Object Methods for Android classes. For example, if I create a simple program and add a Button btn, when I go to use the btn method setBackgroundResource(int) with Content Assist (Ctrl + Space) or Word Completion (Alt + /) neither of them have any proposals. If I type btn.(Ctrl + Space), Content Assist lists; equals(), getClass(), hasCode(), Notify() wait(), shows none of the Button methods!
import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
public class HelloWorld extends Activity {
@Override public void onCreate(Bundle icicle) { super.onCreate(icicle);
setContentView(R.layout.main);
Button btn = Button(this);
btn.(Ctrl + Space) } }

I have ten, possibly more, apps I'm developing that all share logic. 50-75% of the logic is the same - perfect for some time of library or code sharing. However, after reading the posts here and trying to share code in Eclipse, I'm not sure that's going to work. I tried going to project -> properties -> build path -> link source and adding the src and gen folders of the project with the shared code and then importing the classes I need. That seems to work in the IDE, but gives an error during runtime: class not found. This seems to be a common error for people attempting this.
I am slowly deciding that shared code is not the best approach in this scenario. Android doesn't seem to work well with this type of code sharing. For one thing resources are not packed in libraries, but references (R.whatever) must exist so as not to create errors. This can be designed around, but the effort and headache is probably worse than simply creating multiple copies. My experience seems typical, based on what I've read. Is it? Have you experienced success or failure with sharing code and/or custom libraries? Am I off-base in thinking that multiple code copies will be smoother sailing than fighting the shared code approach?

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?

I have some piece of code which uses JNI. I can debug code wrote in Java directly in Eclipse (using ADT). I even have a script, which help me debug native code with gdb. However this is not very comfortable way for doing this.Is it possible to configure Eclipse to use gdb (I guess gdbserver) for debbuging android native applications? Do you know where I could find any description of this?

Is there a way to run unit tests for Android from Eclipse in a way that will instrument the code and measure test code coverage?
I'm looking for a simple way to find out which parts of my application aren't tested yet, fix the test cases and see if that helped.

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

I'd like to bring out an Android app in the near future, so I was wondering how to support a couple of funcitonalities I have got used whilstdeveloping for J2ME and iPhone
first the versioning. With J2ME (using NetBeans as IDE) I had the option to auto-increment the softwwares version every time I compiled it. I was wondering if something like this is available for Eclipse and if so how to use it ? secondly a common code base. Is it possible to have a common code base for several projects ? For example I might have a game which actually uses the same code but needs different graphic resources. I'd hate to have a different project for every game/app and have to manually edit every project's source every time I want to submit a new code-change.

I find it a waste of time that every time I need to enter a string that I have to go edit the strings.xml file manually. What I'd like to be able to do ideally is have Eclipse pop up a dialog box that lets me specify the name of the resource and the value for it. Then Eclipse would generate the code in strings.xml and paste the correct reference to the string at the cursor position.

I want to be able to have two projects, one that contains production code and one that contains test code. This shouldn't necessarily be an Android-specific question, but I'm want to write some unit tests for some non-platform-specific Android code on the host PC.
I created a new Java project so I can run the unit tests on the PC and only include the non-platform-specific classes from the Android project. Both projects are opened in the same Eclipse workspace. I assume I need to somehow include these Android-project sources explicitly in the new project where I'll run the Junit tests, but I can't figure out how to do this.

I did a git on the com.android.music app and then created a project in eclipse from existing code. I chose 2.1 as the sdk target but I am getting errors trying to compile.
Is the music app referencing code that is not part of the 2.1 sdk? Can someone list the steps for how to compile in eclipse?
Description Resource Path Location Type
ArrayListCursor cannot be resolved to a type PlaylistBrowserActivity.java Music/src/com/android/music line 529 Java Problem

I'm pretty new to android, and just finished setup my environment and reading some tutorials. Then I got sdk samples from the web. Okay, what I wanna ask you is that is there a way to start a sample as a project in the Eclipse? I mean like clicking a project file in c# or a solution file.code...
Or, do I need to make a new android project and import (or add files? maybe) them?

I am new to android development and have been playing around with the tutorials offered at developer.android.com.I don't have a problem with projects I create from scratch, but when I start a project from the android sample code provided at android.com or from any other android project, I can never seem to get the bugs out to even run the thing.For example, when loading up the NotePad sample in the android-7 package of samples.would like a general solution, something more global bc this is occurring whenever I pull in anyone's source code from outside.kind of frustrated because I feel that I am spending too much time working out these kinks and not being able to study other people's code against how it performs in the emulator.

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 am trying to read AndroidManifest file to extract all android permissions in eclipse plugin developnebt but have reached a dead end. It is not able to open file in /Project_root_directory/res/AndroidManifest.xml. I searched and found that it is in encrypted form.
But there should be some way because eclipse shows it in human readable format to the end user. I can't figure how to read it using Java.
