如何在android中获取棒棒糖版本后的包名

import android.os.Build;

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        int sdkVersion = Build.VERSION.SDK_INT;
        if (sdkVersion == Build.VERSION_CODES.LOLLIPOP) {
            String packageName = getPackageName();
            Log.d("Package Name", packageName);
        }
    }
}
