Android :: Reference A Jar / Compile It With Dalvik?

Aug 25, 2010

I have a jar that I need to reference from my Android project. I also have the src of the jar, so I could include it in the project itself. I was wondering if referencing a jar vs. compiling it in with the project using Dalvik makes any difference in terms of final Dalvik package size that gets generated.

Android :: How To Compile All Source Files - Default Make Target Does Not Compile All Of Them

Mar 16, 2010

when I compile android ( it does not compile some source files. For example there is external/bluetooth/bluez/sbc/sbc.c which is not compiled. There are also other such files.

It's possible those files need not to be compiled. Or it might be that I need some special configuration to compile them.

Either way, if it is possible, I'd like to compile them. Is there some way to do it? Maybe some "compile_all" make target? (I believe the reason why I want to compile all source files is not important)

Android :: TDD On - Dalvik

Jun 6, 2009

Through out of my Java projects I've got used to TDD with the help of this basic tools

JUnit ( as Unit testing Framework Mockito ( as tool for Stubs and Mock objects EclEmma ( as Java Code Coverage for Eclips

As far as I understand none of them I can use fully when I do coding for Dalvik:

JUnit -- android.jar has its own junit.jar and my assumption is you're supposed to use it, not the latest version from Mockito -- read this one EclEmma -- doesn't support Android JUnit tests

Android :: Is Any Dalvik Bytecoder Available

Jul 6, 2010

I implemented a runtime bytecoder for Java apps based on Javassist. The idea is to introduce code to execute code remotely based on current context. Since the context is not the same at every moment, I need to perform the bytecoding at every execution (if needed). I tried to port my code to Android in order to test it on mobile devices (I already tested it on win mobile and iphone using phoneme and jamvm respectively). However, I could not find any bytecoding tool available for Dalvik. Is there any Dalvik bytecoder available or an ongoing project that I can join/check that is working on this issue? If not, is there any other alternative beside running a decompiler for dex files, and modifying it manually?

Android :: Dalvik And DefineClass

I'm wondering if and how one can load dex or class files dynamically in dalvik, some quick'n'dirty test function I wrote was this:


whereas the Foo interface is this


I also tried the same test driver code with a plain .class file which I didn't expect to work in a dalvik context for the obvious reasons, and it doesn't either.

Anyways, the above test driver throws at defineClass() and it doesn't work and I investigated the dalvik code and found this:

Android :: Delvik Or Dalvik

The Android's VM is called 'Dalvik' on its offical site, but I found the name 'Delvik' has also been used with Android's VM in some forums and kind of articles. So could someone helps me to figure out what's 'Delvik'? it's just a miss spelling or something else?

Android :: Xml Widget Reference?

Mar 1, 2009

To be plain, the android / xml widget reference material is poor at best.Rather than approaching the controls from an xml point of view, its all driven from a class point of view, which is clunky when you want to figure out how to build a good xml UI.Is there any decent documentation with design in mind (tag names, attribute names, etc) or is it just figure it out and struggle through the best you can? I'm on my 2nd android app and losing patience with hunting and pecking for the correct attributes / tags.

Android :: How To Get Reference Book?

Jul 15, 2010

Is there one? I have "Professional Android 2 Application Development" by Meier and "Teach Yourself Android Application Development in 24 Hours" by Darcy/Conder. Both are mediocre at best. Neither is a decent REFERENCE, but rather they are basically structured as tutorials, without nothing in the way of reasonably comprehensive API documentation (which also, BTW, is woefully inadequate on the site). And no sort of in-depth discussion of the structure of the system, so one could perhaps understand it rather than simply using the (inadequate) cookbooks.

Android :: Sort Of Xml Reference?

Aug 31, 2009

Is there any sort of xml reference?

I found this which turned out to be invaluable for me

but I can't figure out how I was supposed to know how to do that, had I not found that post.

I know that the api reference has xml attributes listed for many of the classes... but what about xml tags? Where is it documented that I could build a shape using <padding>, <corners>, <solid> tags?

I'd really like to know where I can find such documentation.

Android :: Use Of Final For Locals On Dalvik

Jan 28, 2010

I've seen a lot of use of final for local primitives.

Presumable to indicate to the compiler that the value shouldn't be changed.

However, what's the implication of this on Dalvik?

I believe final local variables are usually placed on the heap for extended lifetime (for use in inner classes), so is their a runtime overhead rather than using simple locals (which use Dalvik registers)?

Android :: Need To Execute Dalvik Op-Codes

Jun 1, 2009

I would like to execute opcodes directly against the running Dalvik VM instance from within my application on Android. I'm looking for something similar to the C asm function. I have a list of opcodes for dalvik, but I am unfamiliar with how to either execute them directly, or write them out to .class files and execute them against some sort of VM CLI command like dalvikvm from within a running application.

Android :: Invalid Reference During Callback?

Jul 29, 2010

I have an object that is used for calling callback functions ----- static jobject o;

I have assigned the callback function to that object through a pointer, env -----


The same pointer, env, points towards the function CallVoidMethod( ) that uses JNI to reach to the java code.

env->CallVoidMethod(o, methodId, pDeviceId, deviceStatus, statusReason, connectionProgressInfo);

However on calling this function, the system is getting crashed, and VM says that it's an invalid reference to static jobject o and then it crashes.

My code is as follows :
