View 1 Replies View RelatedI'm trying to compile a static library to use on Android but I can't figure out how to compile it. The library uses standard libraries (stdio.h etc...) and libxml2.

The problem is I need to include 'res' resources in the library but can't work out how to do this. Any suggestions?

View 2 Replies View RelatedI have a static library, Foo, that is used by a shared library, Bar. Bar is the native shared library loaded by my Android app. Foo contains JNI functions that are only called by Java code and not by any C++ code in Bar. Because of this, those JNI functions get stripped out of the static library (Foo) when the shared library (Bar) is built. I'm currently using a slightly hacky method to prevent that from happening.So, in this case, is there a way to tell the compiler to not strip the JNI (or any) functions out when linking?

View 3 Replies View RelatedI have a thread on StackOverflow (titled: NoClassDefFoundError for Jersey 2.4.1 client in Android) but I thought I would reach out here in hope of getting a more specific/targeted audience group.I have followed instructions from other posts about the libs Android dependency fix but I still get the issue.
I am using Eclipse Juno, with an Android App targeting API 17. Basically I am getting a NoClassDefFoundError at runtime for the org. glassfish. jersey. model.internal.CommonConfig$1 class located in jersey-client-2.4.1.jar. This is when I just do a Run As... deploy from within Eclipse and it fails when I instantiate the CommonConfig class or one that depends on it internally. The start up log is given below:
[HIGH]12-10 12:25:20.657: I/dalvikvm(10170): Failed resolving Lorg/glassfish/jersey/model/internal/CommonConfig$1; interface 920 'Lcom/google/common/base/Function;'
12-10 12:25:20.657: W/dalvikvm(10170): Link of class 'Lorg/glassfish/jersey/model/internal/CommonConfig$1;' failed
12-10 12:25:20.657: E/dalvikvm(10170): Could not find class 'org.glassfish.jersey.model.internal.CommonConfig$ 1', referenced from method
[code]....
It doesn't seem to find a static inner class of CommonConfig. In the SO forum I tinkered with some options in ProGuard but I've come to learn that this isn't even used in the standard debug mode, only when you do a release build (Export from Eclipse). It would appear that something is happening with the class but I can't figure out why it would not be included if its parent is. Is there some kind of 'light' ProGuard process that goes on when a debug deploy is done? how to resolve this particular case of NoClassDefFoundError?

I'm working on developing a game in Java for android phones and I was wondering if there was a place to view a complete game script so I could see all the components and how it's setup? Kind of like a dissection self-tutorial. Either a developer or website that offers game scripts in their entirety for android phones? I'm pretty new to Java programming and was just looking for a good example of a running game.

View 8 Replies View RelatedIn my Android app, I need to call a non static java method from C/C++. But i get a blunt crash when i do it using GetMethodID/CallVoidMethod()1 methods.
I have done like this:
1. Register the method using GetMethodID() as follows (mine is a cpp file): jmethodID xyz = (env)->GetMethodID( cls, "showxyz", "()V");
2. And I call this method as follows: env->CallVoidMethod(cls, xyz);
3. In java, my showxyz() is defined this way(this basically enables a button which was disabled) void showxyz() {findViewById(R.id.btnPass).setEnabled(true);}
And this crashes.
But I have been using this method of calling Java funcs from C using a set of GetStaticMethodID/CallStaticVoidMethod()(for nonstatic methods) and that works always.
But in this case, I have to call a non-static method and i get a crash.

I am having a static method .In the method when I decalare a variable , it was showing an error in eclipse saying that the variable should be decalared as final.
Can I know the reason for this , y should a variable in a static method be declared as final? I am writng an Android application where I should pass as an argument current Context of that application. So, when I pass the current context to the method and trying to copy it in a local variable , I am getting this error saying that the variable should be declared as final.
My method is like this:
CODE:.............
Error is showing at line where Context myctx=ctx; is declared and asking me to declare it as final.
I want to use somthing like: MyLogger.e("MyApp","I have an error.");
In a cross-plattform project, where MyLogger should be static to make it available in the whole project.
So I was trying something like:
CODE:.........
The compiler complains about the static. How do I do this? Is it possible at all? If not, what's the right approach?
