Importing external .jar file to Android project [duplicate]

Answer 1

Here is what I did, and it worked :

• Right-click on your project
• Build Path > Add External Archives
• Select your archive (.jar)

The library.jar will be added to the 'Referenced Libraries' in your project, but not in the folder of your project. I can now run my project with that external library, and I don't get errors, but I don't know if it is the usual way to do it. My archive is not in the 'libs' folder, as everyone. You should try what I did.

Answer 2

Put the JAR in your project's libs/ directory. Then Build Path -> Library -> Add JAR should allow you to pick the one out of your project. IIRC, this works with Eclipse.

If you decide someday to dump Eclipse, just having your JAR in libs/ is enough -- the command-line build tools will pick it up automatically.

UPDATE: If you have the R17 or newer version of the ADT Eclipse plugin, now you only need to add a libs/ directory and put your JAR in there. It will automatically be added to your build path, much like with command-line builds.

Answer 3

Check the version of jar and also your system Java version. If jar version is compatible to the system version it will run.

Moreover, check the Jar by running java -jar filename.jar on the command prompt.

After that do the same thing as mentioned in the above version.

If not please pass your jar and sample code.
