Android error: missing method body, or declare abstract #575
I'm trying to run the Android example found in BridJ/Examples/AndroidExample. I am able to get dependencies resolved after downloading BridJ and using maven to build it successfully. I place the generated bridj-0.7.1-SNAPSHOT-andorid.jar in app/libs, and I place everything under BridJ/src/main/android-libs in app/src/main/jniLibs. I copy the files in BridJ/Examples/AndroidExample/ to my Android project. All of the BridJ dependencies are resolved.
The problem is that MainActivity won't compile. The error on
public static void helloLog(Pointer<Byte> logThis);
says "Missing method body, or declare abstract". If I declare the method to be native, then I get the following runtime error.
java.lang.UnsatisfiedLinkError: No implementation found for void yada.yada.yada.MainActivity.helloLog(org.bridj.Pointer) (tried Java_yada_yada_yada_MainActivity_helloLog and Java_yada_yada_yada_MainActivity_helloLog__Lorg_bridj_Pointer_2)
I haven't added or removed anything from MainActivity.java, but for what it's worth, I'm pasting the source for that below. Any ideas?
