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 call...
I'm trying to use the SmugFig SmugMug API on Android. It was designed for J2SE I would imagine, so I'm not sure it will even work on Android, but I figured it was worth trying as opposed to trying to create my own API. When I load the project though, I get the following error: Conversion to Dalvik format failed: Unable to execute de...
I'm curious, why did Sun decide to make the JVM stack-based and Google decide to make the DalvikVM register based? I suppose the JVM can't really assume that a certain number of registers are available on the target platform, since it is supposed to be platform independent. Therefor it just postpones the register-allocation etc, to the ...
Hello, As I know Dalvik VM does not support generational GC as default. But, I found "WITH_OBJECT_HEADERS" compilation flag which could be related with generational GC from HeapInternal.h file. typedef struct DvmHeapChunk { #if WITH_OBJECT_HEADERS u4 header; const Object *parent; const Object *parentOld; const Object *m...
I am currently developing an android app in eclipse using: One project for the app One project for the tests (Instrumentation and Pojo tests) In the test project, I am importing the mockito library for standard POJO testing. However, when I import the library, the compilation time skyrockets from 1 second to about 30 seconds in eclip...
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: public void testLoader() { InputStream in; int len; byte[] data = new byte[2048]; try { in = context.getAssets().open("f.dex"); ...
Hi, I'm trying to make a bundle for Felix on Android which may take photos regularly. All the code compiles well and it can be resolved by Felix, but when I try to start it, I get an exception (java.lang.VerifyError) and this trace in logcat : I/dalvikvm( 738): Failed resolving Lbarcode/android/CameraHandler; interface 1 'Landroid/har...
Hey y'all, So I ran into a problem today while working on my Android program. I have a class that turns that an XML string into a Java object (third party) and it works fine in as a regular java project but on Android I get this weird error: 06-21 22:44:26.402: DEBUG/App(259): java.lang.ClassNotFoundException: com.package.mycode.Class ...
Hello, As I've heard from Google IO 2010 session, Dalvik JIT compiler just support ARM processor. Do this mean my own build of Android source on Linux X86 or Mac OS X can not support JIT compiler? Should I use some target board with ARM processor to test Dalvik JIT compiler? Thanks! ...
Dear Sirs, We are implementing some of the event callbacks of JVMTI ( http://java.sun.com/j2se/1.5.0/docs/guide/jvmti/ ) in the Dalvik VM. However, we are having trouble in event Method_Entry and Method_Exit. In our current implementation, we can only intercept the Method_Entry event of the some system initialization methods, including...
hi there! i have a severe problem with eclipse, where i need to compile a somewhat larger class. by "larger" i mean, the class has about 5000 lines of code... problem is that on saving this project, eclipse takes several seconds (30-40) to "build the workspace". to be exact, it says "50%" and keeps saying that for 30-40 seconds. then, ...

I am interested in integrating Scala (or some other non-Java JVM-language) into the android platform. I am not referring to writing an android application with Scala, that I did early early on, but actually hooking into the build process that builds the android platform source tree. I imagine this will be a matter of hooking into the mak...
Hi guys, I'm currently implementing some image processing code for Android. I'm aware of the memory limits and am happy to code within them. However, I cannot find any documentation that lets me work out how many bytes are used for each instance of a given class that I might want to instantiate (on the heap). I'm an experienced C++ pro...
With Oracle suing Google over Dalvik's patent infringements, I'm wanting to get off the Java bus I've been on for 10+ years. I really enjoy coding in Java, love the tools (eclipse, profilers, etc...), cross platform, garbage collection, etc... What is the best alternative out there? I'd like to build cool gui's, mobile apps, web apps,...

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. ...
