Apps External Jar file error

[dcreedon]

Hi,
I have included an external jar file in eclipse as a user library. Everything compiles and deploys correctly to my android emulator.

When it comes to calling the activity that uses the external jar classes it craps out. I set a breakpoint at the offending area and it is reporting that it cannot find the class that I was trying to use.

The jar file is from Barbecue project

Stack extract:

ClassNotFoundException.<init>(String, Throwable) line: 59
VMClassLoader.loadClass(String, boolean) line: not available [native method]
BootClassLoader.findClass(String) line: 1057
BootClassLoader.loadClass(String, boolean) line: 1124
PathClassLoader(ClassLoader).loadClass(String, boolean) line: 567
PathClassLoader(ClassLoader).loadClass(String) line: 532
LoyaltyCard.outputtingBarcodeAsPNG() line: 32
LoyaltyCard.onCreate(Bundle) line: 21


Please Help

Hi Damian,

Don't forget that Android Java isn't standard Java. It uses its own JVM.
Android will only recognise classes that were compiled with the Android java compiler, so standard java .class files that make up the external jar file won't work.

If you have the source, and recompile using the Android SDK then you might have more luck.
