<div class="jive-rendered-content"><p>Hi there,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I am just working on an instrumentation project. Target is to instrument android applications. I know its a different VM, but I found a way that works :-).</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I do the instrumentation, after the sources are compiled to bytecode, so I have real Java Bytecode. This I can manipulate with javassist. After this the normal way of the android build process runs. All is controlled by ant scripts. The package (apk) is built without errors.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Instrumentation works good so far, but when I try to run the application on a device, I get an exception, calling "Method not found" or similiar.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I instrument something that uses a java.util.Set. When I run the application, the above mentioned exception is thrown. I gues, this is because the javasssit compiler knows about the java.util.set, cause I added the package to the classpool. but somehow it is no longer available, when the javassist process is done.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>my question:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>is there any possibility to put all needed dependencies, occured in javassist to the bytecode, produced by the javacompiler?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>If you don't understand my problem, I can try to describe it a different way. But if you understand it, I would be nice to help ma in any way.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks a lot in advance.</p></div>
