Question

I’m trying to use a jar file in an android application on the linux command line. I’ve read:
Android include .jar in ant compilation
Which is the same thing but never got a working answer.
Tried this:
How to add external jar libraries to an android project from the command line
but it didn’t work, still gave the same error message.
The error is:

-compile:
     [javac] Compiling 4 source files to /home/bianca/Documents/sem12012/FIT3140 /code/jackson-example/bin/classes
    [javac] messagemain.java:4: package org.codehaus.jackson.map does not exist
    [javac] import org.codehaus.jackson.map.ObjectMapper;

BUILD FAILED
/home/bianca/Downloads/android-sdk-linux/tools/ant/build.xml:602: The following error  occurred while executing this line:
 /home/bianca/Downloads/android-sdk-linux/tools/ant/build.xml:622: Compile failed; see the compiler error output for details.

So I’m guessing it’s a problem with importing the jar. I have the jar stored in ./lib.

EDIT:
I put the jar in libs according to a suggestion in an answer, it gives the same error.
ant.properties is all comments, local.properties and project.properties have not been changed from the automatically generated one. build.xml has not been changed, it’s just the automatically generated one.

Answer 1

Use libs/, not lib/. The JAR will automatically be included as part of the compile process, and the JAR’s contents will be packaged into your APK.
