Add new lib in java android

To add a new library in a Java Android project, you can follow these steps:

Step 1: Add the library to your project's build.gradle file

Open your project's build.gradle file in the Android Studio editor.
Add the following code to the dependencies section:
```
dependencies {
  implementation 'com.example.library:library-name:version'
}
```
Replace com.example.library with the actual library's package name, library-name with the name of the library, and version with the version number of the library.

For example, if you want to add the Google Maps library, you would add the following code:

dependencies {
    implementation 'com.google.android.gms:play-services-maps:17.0.0'
}

Step 2: Sync your project

Click on the "Sync Now" button in the top-right corner of the Android Studio editor to sync your project with the Gradle files.

Step 3: Add the library to your project

In the Android Studio editor, go to the "Project" view and navigate to the app directory.
Right-click on the app directory and select "Open Module Settings" (or press Ctrl + Shift + Alt + S on Windows/Linux or Cmd + Shift + Alt + S on Mac).
In the "Module Settings" window, click on the "Dependencies" tab.
Click on the "+" button next to "Dependencies" and select "Library" from the dropdown menu.
Select the library you added in Step 1 and click "OK".

Step 4: Use the library in your code

You can now use the library in your Java code by importing the library's package and using its classes and methods.

For example, if you added the Google Maps library, you would import the com.google.android.gms.maps package and use its classes and methods to create a map:

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;

public class MyActivity extends AppCompatActivity {
    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my);

        MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
        mMap = mapFragment.getMap();
    }
}

That's it! You have successfully added a new library to your Java Android project.
