Question

我使用的是百度地图（ SDK版本：4.5.2 ），但他们没有显示地图。相反，只显示网格线。

代码：

robocopy $f $g /MIR

public class MainApp extends MultiDexApplication { @Override public void onCreate() { super.onCreate(); SDKInitializer.initialize(this); } } class :(此代码在Kotlin中。如果您需要Java等效的代码，请在下面发表评论。）

BaiduMapActivity

build.gradle文件：

class BaiduMapActivity : BaseActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_baidu_map)
    }

override fun onResume() {
    super.onResume()
    bmapView.onResume()
   }
}

图书馆结构：

结果如下。应用程序运行正常，但只显示网格线并且地图不可见。

可能的原因是什么？

Answer 1

可能有几种选择：

没有Api密钥添加到清单
Api密钥绑定到错误的SHA1或错误的软件包名称
使用模拟器。根据我的测试，从未在模拟器上工作，但在真实设备上工作得很好（我打赌这个，因为我没有看到你的日志上的百度通信错误）。

Answer 2

尝试使用中国VPN，然后查看地图是否已加载

地图不渲染。仅显示网格线
