I don’t have any experience of this, but a bit of digging shows that the library should be unloaded when the classloader which loaded the library is garbage collected. Links: Invocation API docs (Sun) – look for “Library and Version Management” Java JNI DLL Unloading tutorial
As far as I know, there are no static compilers for JavaScript. It is certainly theoretically possible; however, a static compilation of JavaScript would need a very heavyweight runtime to support all of its features (such as dynamic typing and eval). As a small aside, when presented with the need to statically compile Python (another … Read more
Let’s say that logcat show you the following crash log (this is from one of my projects): I/DEBUG ( 31): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** I/DEBUG ( 31): Build fingerprint: ‘generic/sdk/generic:2.3/GRH55/79397:eng/test-keys’ I/DEBUG ( 31): pid: 378, tid: 386 >>> com.example.gltest <<< I/DEBUG ( 31): … Read more
When you define functions in an interpreted language (as opposed to a compiled language). You have access to the file / string / text that defines the function. In JavaScript for example you can read the definition body text of a function you have defined. If you try to do the same for a function … Read more
Microsoft has an article describing how you can Compile MSIL to Native Code You can use Ngen. The Native Image Generator (Ngen.exe) is a tool that improves the performance of managed applications. Ngen.exe creates native images, which are files containing compiled processor-specific machine code, and installs them into the native image cache on the local … Read more
There used to be a tool called GCJ that was part of GCC, but it’s been removed. Now, all the links in the GCC site re-direct to their non-GCJ equivalents. NB: the comments all refered to my original answer saying you can compile Java to native code with GCJ.
