importing jar libraries into android-studio

Question

android-studio 0.2.7
Fedora 18

Hello,

I am trying to add the jtwitter jar to my project.

First I tried doing the following:

1) Drag the jtwitter.jar into the root directory of my project explorer, see picture
2) File | project structure
3) Modules | yamba-yamba | dependencies
4) Click the plus sign | jars or directories | and navigate to jtwitter jar | click ok

When I import the jar file I get the following error:

import winterwell.jtwitter.Twitter;

Cannot resolve symbol winterwell
Gradle: error: package winterwell.jtwitter does not exist

I researched and found that android-studio has some issues and that you have to edit the build.gradle file yourself.

So I tried adding this to my build.gradle file:

dependencies {
    compile files('libs/jtwitter.jar')

And got an error message: cannot resolve symbol dependencies

Another question, where would the libs folder be. Does it mean the External Libraries?

Any help will be most helpfull,

Answer 1

Try this...

1. Create libs folder under the application folder.
2. Add .jar files to libs folder.
3. Then add .jar files to app's build.gradle dependency.
4. Finally Sync project with Gradle files.

1.Create libs folder:

2.Add .jar to libs folder:

3.Edit app's build.gradle dependency:

• Open app/build.gradle

4.Sync project with Gradle files:

• Finally add .jar files to your application.

UPDATE:

Here I'm going to import org.eclipse.paho.client.mqttv3.jar file to our app module.

1. Copy your jar file and paste it in directory called libs.

2. Press Ctrl + Alt + Shift + s or just click project structure icon on the toolbar.

3. Then select your module to import .jar file, then select dependencies tab.

4. Click plus icon then select File dependency

5. Select .jar file path, click OK to build gradle.

6. Finally we're imported .jar file to our module.

Happy coding...
