Android :: Versioning And Common Code-bases With Eclipse
Sep 14, 2010
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 have an Android application composed by several Activities. Most of them need to check whether an active network is available or not:
public boolean isNetworkAvailable() {
ConnectivityManager cm = (ConnectivityManager)
getSystemService(Context.CONNECTIVITY_SERVICE);
TelephonyManager tm = (TelephonyManager)
getSystemService(Context.TELEPHONY_SERVICE);
...
}
I would like to move that code to a helper class in order to avoid the need to write that code in every Activity, but calls to getSystemService are only allowed from an Activity. The other alternative is to move that code to a parent activity use inheritance but:
Every activity already extends from android.app.Activity
Some of my activities already extend from a common my.package.BaseActivity
(Activity <- BaseActivity <- XXXActivity)
What do you recommend in this case? Is there any other alternative?

I have a set of common code (including .java files and resources), which I have to use for two similar applications with different package names (for different vendors). How can I maintain two packages which share the common code without making two copies of the common source?

I have done some cusomtizations on general user interface behavior. I would put those features into my applications. Therefore, I package my source code as a jar and add this external library to my applications.
As my cusomtization include some inflation of xml files, I put those resource in my package. However, when I finished compiled my application and ran it, it reports error. It seems cannot locate the xml file in the jar. (My debugger stop while inflate the xml file). Do I miss any step to use my jar file?

I am currently moving from Xcode and iPhone development to Android with Eclipse. I want to have a shared code project so that I can store all the code to be shared across apps in one common library. However it would appear that the only android project available is for applications and not for code libs how can i achieve this?

Using the licensing technique described here http://developer.android.com/guide/publishing/licensing.html I'm trying to test what happens when: - I would upgrade my LVL protected app to a new version - Some user hasn't upgraded yet Will the user with the old version still be able to continue? Will the licensing server return LICENSED_OLD_KEY as I expect it to, and thus allow access?
The scenario I used to test this: - uploaded to market a signed version 1.0.0 (did not publish it) of my app which has never been published nor uploaded before - setup test account and let the test response be LICENSED - on Nexus1 tested and verified that when using the apk (so the one in <project>/bin), LICENSED is returned. - increased versionCode and versionName to 1.0.1, signed and uploaded that version to market (didn't publish) - on N1 installed the new apk (again the newly compiled one from <project>/bin). LVL returns NOT_MARKET_MANAGED so indicating that it's not available in the market. But I expected LICENSED_OLD_KEY to be returned.
Am I trying something that's not possible to test? From other posts like this one: [url] and this one: [url]is suggested that the above scenario should work...
If this is not possible to test before publishing an app, did anybody try this out in the field: will LICENSED_OLD_KEY be returned for older versions that previously got LICENSED as an answer?

Called up the local Verizon corporate store to see if they had any demos in store (they only had a dummy model, not worth going to see that), and they asked if I wanted to make an appointment. So I made the 10:30 appointment even though I really want to just purchase it online. Guy I spoke with was super excited about the phone as well, he said the appointment wasn't a guarantee but that he would be calling me to come in on the 15th . Couple backup plans in the works now.

We're planning to export an application layer AIDL interface. What are some best practices with regards for managing version compatibility? Does Android provide any version-related mechanisms for AIDL interfaces?

Eclipse HELIOS (3.6) Code Assist very slow?

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.
See https://bugs.eclipse.org/bugs/show_bug.cgi?id=317979

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.

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.

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 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
