我正在使用百度地图（SDK 版本：4.5.2），但地图没有显示。相反，仅显示网格线。
代码：
public class MainApp extends MultiDexApplication {
@Override
public void onCreate() {
super.onCreate();
SDKInitializer.initialize(this);
}
}
BaiduMapActivity类：（此代码在 Kotlin 中。如果您需要此代码的 Java 等效项，请在下面发表评论。）
class BaiduMapActivity : BaseActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_baidu_map)
}
override fun onResume() {
super.onResume()
bmapView.onResume()
}
}

图书馆的结构：
结果如下。应用程序运行良好，但仅显示网格线且地图不可见。
可能的原因是什么？
