Android :: Unable To Generate R.java Manually On Linux Platform / Way To Do It
Mar 31, 2010
I have a question.
I am developing android application on Linux platform because i have to make a system.img with a application.
When adding a drawable resource and building the project with mm command, i met a below error.code..
At above error, the icon_send_type is the added resource.
This error occurred because the mm command did not generate R.java.
So, i want to know how to generate R.java by a manual on Linux platform.

I am getting a parsing error and I do not know why (I am new to programing). Because of this error, R.java disappears and I end up having more errors. Hopefully someone can help me out. Here is where the error comes from: list.xml. Code...

I have an Java class with a static final method getAll:
CODE:..............
Now I want to hand in null as a value for the where statemant so that it will just be ignored later on in the code. Anyway in the testcase for this method I have: Vector<Category> categories = Category.getAll(context, null);
Which then in turn gives me a NoSuchMethodError. I don't know exactly why it does that. The only thing I could imagine is that the null I hand in would not match the signature of the above method. But how can I overcome this? I already thought of overloading. But this would just end in rewriting most of the code. At least when I do it, how I think.
This is the stack trace I get:

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

Is there a way to achieve the following in Android?
1. generate a Java stack trace in Android. In J2SE, we use to use something like this - send a signal to the Java Virtual Machine; the Java Virtual Machine generates a stack trace for you; or we can also use debugging tools or Java API calls.

We have a desktop/web java application and also getting into Android development.Ideally we would like one app that runs both on desktop and android.From what we can tell, it's not much possible to run normal java apps on android. But wondering if it can do it the other way? That is, run android apps easily on the desktop (without the user install the sdk or android emulator)?In a prefect world we'd like one app for both platforms. Realistically though it seems like we're going to have to have one app with two front ends?

I wanted to check whether there is any JAVA Coding standards in Android platform for performance improvements.
For Example, like an Effective Java code in J2EE environment is to defined the number of elements in the ArrayList constructor rather leaving it blank (new ArrayList(noOfRows)) etc. I definetly suspect these performance tuning tips should be available because of the memory and resource constraints.

I know Java apps can be run in Android. But what I want to know is this: I have a perfectly normal Java app and I want to port it to an android platform. What changes would I need to do to my app in terms of GUI and other code to make it usable in Android? I know Android uses XML file to control the look and feel of its app. So would I need to change my GUI completely? I just want to know the general overview of how porting may be done. If anyone could point me to right resources, that would be great. Also, for your info I'm a newbie to developing android app.

Anywho, I want to go into Gmail, compose a new email, and be able to select contacts (or even have the app provide a look-ahead list based on what I type). This is exactly how the Gmail app for my Blackberry 8830 worked so I don't understand why there seems to be less functionality no an Android phone. In any case, it seems that no matter what, all I can do is manually type in email addresses. Also, I know I can go into Contacts (People) and select a person's email. This brings up a menu option to email using Gmail or my Exchange email account. This in't good enough because all I can do is open a new email to one person this way. What if I want to email 10 people!?

i successfully got into adb in recovery mode fairly easily on my ubuntu 10.4 laptop using the following method- this should also work for a linux live boot from a usb flash drive
in one terminal tail and follow log messages
~$ tail -f /var/log/messages
In another terminal run the loop
Then
1. plugin usb and keep it plugged in
2. remove battery, eject sd card.
3. put battery in
4. press vol- and power
5. after around 6 seconds, your terminal with the log will show something like "new high speed USB..."
6. press vol- to select recovery
7. press the power button
8. IMPORTANT- as soon as you see a new log entry (something like "USB disconnect"), pop in the sd card
check your loop terminal for adb. if it doesn't work, repeat at step 2

Hi, custom classes which are part of a framework, so nothing graphical. One of those (singleton) classes is a Logging class which send logs to my server. I noticed that even though I can call the classes methods in my service it actually won't be logging anything... In my specific example it's osmething like : Logger.getInstance().log("Whatever I want to Log"); Obviously the getInstance is a static method so it can be accessed from anywhere within my project right away.. I was wondering though why this method for example isn't getting called ? Also how do I debug a Service ? Btw I am using of IPC from one of my Activities which gets bound to the service and can start/stop the music for example...

I 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:

I wrote an android app and so far it works perfect except for on one phone. It is the exact phone that I have with 2.2 on both phones and mine works perfect. The other phone is getting force close all the time but only when opening an activity that queries my image DB and tries to show a gallery. Every activity crashes in the same place, the viewimages. At first I thought it was the intent that was doing it but one of the activitys does not have the intent, it opens the images below the gallery. This works on the emulator, on my moto droid and on a few other different droids. Here is the code for the gallery and my bitmap decoder.
The error is below that.

I know android is based on linux, does this mean it can run any and all linux applications? If so has anyone tried to run anything like wine? I also noticed that by default you cant run apps directly from sd card, but i saw a modification on a site that lets you change it so you can, so technically speaking is there any limit on the size of sd the G1 can handle?

I'll start by saying that I'm REALLY new to OpenGL ES (I started yesterday =), but I do have some Java and other languages experience. I've looked a lot of tutorials, of course Nehe's ones and my work is mainly based on that. As a test, I started creating a "tile generator" in order to create a small Zelda-like game (just moving a dude in a textured square would be awesome So far, I have achieved a working tile generator, I define a char map[][] array to store which tile is on :Code...
