迷上了代码！融云&高德地图-实现地理位置发送
1:注册高德地图开发者账号，创建应用、获取高德地图的 appkey
2: jar 包建议直接从 融云 demo 中拷贝。因为某地图厂商的版本兼容做的不好。可能你下载的新版本的 jar
在老版本的实现代码中就找不到这个接口。或者那个接口变动了

2: jar 包建议直接从 融云 demo 中拷贝。因为某地图厂商的版本兼容做的不好。可能你下载的新版本的 jar. 在老版本的实现代码中就找不到这个接口。或者那个接口变动了
3: 参考 demo 代码 在 RongCloudEvent.java 上实现了 地理位置提供者接口 。 onStartLocation 方法中点击开启 地图的 Activity
public void onStartLocation(Context context, LocationCallback locationCallback) {
* demo 代码
开发者需替换成自己的代码。
DemoContext.getInstance().setLastLocationCallback(locationCallback);

将代码拷贝 和 相关资源文件拷贝以后就能实现。下面对代码逻辑做一下介绍
代码整体分两部分 一部分是发送位置逻辑 一部分是从会话界面地理位置消息点击进来逻辑。主要逻辑是 发送位置逻辑
public void onLocationChanged(AMapLocation aMapLocation) {
if (aMapLocation != null && aMapLocation.getAMapException().getErrorCode() == 0) {
如果卡在这个 if 判断没有进来那说明你配置的高德相关的 jar 、key 、storeFile(此处在 gradle 配置) 配置高德环境有问题。此处具体咨询高德地图
另外需要值得注意的一点是获取静态缩略图的问题
private Uri getMapUrl(double x, double y) {
String url = "/v3/staticmap?location=" + y + "," + x +
"&zoom=17&scale=2&size=150*150&markers=mid,,A:" + y + ","
+ x + "&key=" + "ee95e52bfbcfbcf21df0";
NLog.e("getMapUrl", url);
return Uri.parse(url);
最后组拼的 key.在高德官网解释是说需要配置自己的 高德key.这里是个坑，我拿着自己的 key 去中解析 返回错误码 10009
当时给愁坏了。后来朋友提示随意拿个别人的 key 绑定了 web api 的去使用试试。结果还真行。所以在此处参考博文的小伙伴直接用上面 demo 提供的 key 即可。
点击地理位置消息预览的逻辑 在 RongCloudEvent.java 重写消息点击事件
if (message.getContent() instanceof LocationMessage) {
Intent intent = new Intent(context, AMAPLocationActivity.class);
intent.putExtra("location", message.getContent());
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
在 AMAPLocationActivity 截取并且判断这个 intent
if (getIntent().hasExtra("location")) {
isPerview =
mMsg = getIntent().getParcelableExtra("location");
tvCurLocation.setVisibility(View.GONE);
returns.setVisibility(View.GONE);
if (model) {
CameraPosition location = new CameraPosition.Builder()
.target(new LatLng(mMsg.getLat(), mMsg.getLng())).zoom(18).bearing(0).tilt(30).build();
show(location);
aMap.addMarker(new MarkerOptions().anchor(0.5f, 0.5f)
.position(new LatLng(mMsg.getLat(), mMsg.getLng())).title(mMsg.getPoi())
.snippet(mMsg.getLat() + "," + mMsg.getLng()).draggable(false));
最后的 return 不继续执行代码。完成当前位置的预览即结束
发送地理位置&高德地图结束 有任何疑问可以在下方留言。高德地图相关的问题可登陆高德地图官网进行咨询高德地图 LocationManagerProxy为什么引用不到啊

迷上了代码！问题：高德地图混淆代码后定位失败
描述:android高德地图android&studio编译
因为在我的工程里出现了这种情况。不混淆代码可以，一旦混淆代码后，定位那部分的方法虽然可以调用，但一直是定位失败，随后我下了其官方的demo，混码编译之后也是如此，有人知道怎么解决吗？
我的用的是android&studio
下面是我代码混淆的编码-keep&class&com.nostra13.universalimageloader.**&{&*;&}
-dontwarn&com.pgyersdk.**
-dontwarn&com.viewpagerindicator.**
-dontwarn&com.handmark.pulltorefresh.library.**

#高德相关混淆文件
-keep&&&class&com.amap.api.location.**{*;}
-keep&&&class&com.aps.**{*;}
-keep&&&class&com.amap.api.services.**{*;}
下面是我调用定位的方法
mLocationManagerProxy&=&LocationManagerProxy.getInstance(this);
&&&&&&&&mLocationManagerProxy.setGpsEnable(false);
&&&&&&&&mLocationManagerProxy.requestLocationData(
&&&&&&&&&&&&&&&&LocationProviderProxy.AMapNetwork,&-1,&15,&this);
以上介绍了“高德地图混淆代码后定位失败”的问题解答，希望对有需要的网友有所帮助。
