Android :: How Java Generate Signatures For Methods

Oct 1, 2010

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:

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 :: Development - Debugging Tools / Generate A Java Stack Trace?

Apr 29, 2010

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.

When I now try ant release I get this error: build.xml:65: java.lang.NullPointerException. This project builds fine under Eclipse. I have no idea where to even begin to figure this out. I wouldn't bother with this except that I need to use ProGuard later on (which I have not done yet).

Android :: Does The Dalvik File Format - .dx - Support More Instructions Than Java .class File

Is there anything the Dalvik VM supports (in terms of bytecode) which is not used currently because the .class files don't have it?

As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?

Android :: Android / Java - Call Function In Separate *.java File?

Aug 16, 2010

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.

For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}


9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!

Android :: Java Rare And Impossible Exception Causing Force Close

Apr 19, 2010

I have an interesting problem being reported to me from an android application I have published. I have a two-dimensional array that I am iterating through using two for loops like so:

for (int i = 0; i < arr.length; ++i)
{
for (int j = 0; j < arr[i].length; ++j)
{
if (arr[i][j] != 0)
// does stuff
}
}

The problem is, somehow arr[i][j] != 0 is throwing an ArrayIndexOutOfBoundsException. But very rarely. I have thousands of people use the app on a daily basis and get maybe twenty force close reports. Is this something I can't avoid, maybe a problem with the phones memory, etc. or is there something I can do that I haven't thought of yet?

Android :: Runtime (703) Java.lang.Verify - Force Verification Of Library Files

Jan 11, 2010

I'm using the Android Development Toolkit (ADT) in Eclipse Galileo. I've created a project in which to develop some util classes, which I intend to use in several upcoming Android projects. However, when I come to use these util classes (deployed as a jar and included in the Android project as a user library), I get a java.lang.VerifyError during the startup of the emulator. Can I force the verification of these library files, or do I need to include them as part of the Android project, and not as an external jar?

Android :: Magic Behind R Java File

Jan 12, 2010

I have been having quite some problems with R.java file. Now I have decided to do a backup and delete the file to see what happens. Nothing happened, so I created an empty R.java file and hopped for the best. Now Eclipse seems to figure out that the file was tempered with and even issues a warning: R.java was modified manually! Reverting to generated version. And that's all there is. I tried building it manually but got no results. So, I have two questions: 1. what should I do to force Eclipse to generate the file. 2. what is happening here? How is the file created, where is the code that is generating the file? I would appreciate any help.

Android :: Installing Apk File In Java

Mar 3, 2009

I'm trying to write a java program that will install an apk file on android. I saw that there is an Intent action: ACTION_PACKAGE _ INSTALL, available and the developer reference says: "Broadcast Action: Trigger the download and eventual installation of a package" So I wrote a program like so:

Intent newintent = new Intent(Intent.ACTION_PACKAGE_INSTALL); File apkFile = new File("/data/data/HelloAndroid.apk"); newintent.setData(Uri.fromFile(apkFile)); sendBroadcast(newintent);

But this fails to do the intended task (which is download and install the application). I'm not able to figure what is happening to this broadcast intent, no logs get printed in LogCat. Any pointers on where to look or how to proceed?

Android :: R Java File Not Updating With UI Element's Id

Even when I add a new xml file with UI elements, it still doesn't show up in the R.layout class. I have made checked the ids on them and they have the correct format (I think): android:id="@+id/my_button". What could be the problem? Do I need to compile the code first? UPDATE: I have already tried adb kill-server then adb start-server. It doesn't seem to help. I have also tried R.id.my_uielement, it doesn't register either.

As i told before, im almost sure that this is possible, but i dont know how to link that second file so, can anybody help me?

Android :: No Generated R Java File In Project

I have errors on Notepadv2.java and in res/layout/note_edit.xml and both seems to be related to the fact that the generated R.java is missing. Here is my import statements in Notepadv2.java:

import android.R;
import android.app.ListActivity;
import android.content.Intent;

import android.os.Bundle;

Occasionally that happen and so I did the usual Project => Clean... as I always do in such cases. But this time I now have the odd effect that almost all files show bugs, and looking closer it's that the compiler can't find the R-file (which is indeed missing from the gen subtree). How do I force eclipse to rebuild that file?

Android :: Read A Segment Of File In Java / Droid?

Aug 27, 2010

I'm sure this might be a simple question, but unfortunately this is my first time using Java and working the Android SDK.

I am uploading files on Android using the Apache HTTP libraries, in particular using the MultipartEntity.

I'm uploading to a service that allows me to send them chunks of the file, and once complete, they'll reassemble the chunks. I'd like to take advantage of this feature.

Here's the scenario.

File FOO.BAR is 20 MB. I'd split it into some arbitrary chunk size, let's say 1 MB, which means 20 chunks. Chunks #3 and #14 fail (maybe the cellular/WiFi connection was bad). I can now re-upload just these two chunks and everything will be good.

What I'd like to know is how can I read only part of a file (like the data between 3MB and 4MB)?

The file piece should be an InputStream or File object.
