यहां दिए गए कोड सैंपल में, addPolyline तरीके को कॉल करके, पॉलीलाइन जोड़ने और उसे 3D स्पेस में रखने का तरीका बताया गया है. इस कोड सैंपल का इस्तेमाल करने के लिए, सेटअप और अपने ऐप्लिकेशन में 3D मैप जोड़ना में दिए गए निर्देशों का पालन करें. इससे, Android Studio प्रोजेक्ट को बुनियादी 3D मैप के साथ सेट अप किया जा सकेगा. इसके बाद, MainActivity.kt फ़ाइल में यह कोड जोड़ें:
