[Android] HMS Core地理围栏能力助你实现指定范围人群的精准消息推送

• 在测试设备上安装演示应用。
  
• 启动演示应用程序，点击地理围栏屏幕上的添加地理围栏，然后设置相关参数以创建地理围栏。
  
• 等待地理围栏被触发。
  
• 在触发地理围栏时检查收到的消息。
  

• 配置SDK的Maven仓地址。
  
• 
  

buildscript {
i.  dependencies {
ii.    ...
iii.    // 增加agcp插件配置，推荐您使用最新版本的agcp插件。
iv.    classpath 'com.huawei.agconnect:agcp:1.6.0.300'
  }
v.}

pluginManagement {
  repositories {
    gradlePluginPortal()
    google()
    mavenCentral()
    // 配置HMS Core SDK的Maven仓地址。
    maven { url 'https://developer.huawei.com/repo/' }
  }
}
dependencyResolutionManagement {
  ...
  repositories {
    google()
    mavenCentral()
    // 配置HMS Core SDK的Maven仓地址。
    maven { url 'https://developer.huawei.com/repo/' }
  }
}

//应用级的“build.gradle”文件
dependencies {
  implementation 'com.huawei.hms:location: 6.4.0.300'
  implementation 'com.huawei.hms:push: 6.3.0.304'
}

• 在 AndroidManifest.xml 文件中声明系统权限。
  

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARES_LOCATION" />

• 触发地理围栏。
  

if (checkStyle(geofences, data.uniqueId) == false) {
  LocationLog.d("GeoFenceActivity", "not unique ID!");
  LocationLog.i("GeoFenceActivity", "addGeofence failed!");
  return;
}
geoBuild.setRoundArea(data.latitude, data.longitude, data.radius);
geoBuild.setUniqueId(data.uniqueId);
geoBuild.setConversions(data.conversions);
geoBuild.setValidContinueTime(data.validContinueTime);
geoBuild.setDwellDelayTime(data.dwellDelayTime);
geoBuild.setNotificationInterval(data.notificationInterval);
geofences.add(geoBuild.build());
LocationLog.i("GeoFenceActivity", "addGeofence success!");

GeofenceRequest.Builder geofenceRequest = new GeofenceRequest.Builder();
geofenceRequest.createGeofenceList(GeoFenceData.returnList());
if (trigger.getText() != null) {
  int trigGer = Integer.parseInt(trigger.getText().toString());
  geofenceRequest.setInitConversions(trigGer);
  LocationLog.d(TAG, "trigger is " + trigGer);
} else {
  geofenceRequest.setInitConversions(5);
  LocationLog.d(TAG, "default trigger is 5");
}
final PendingIntent pendingIntent = getPendingIntent();
try {
  geofenceService.createGeofenceList(geofenceRequest.build(), pendingIntent)
    .addOnCompleteListener(new OnCompleteListener<Void>() {
      @Override
      public void onComplete(Task<Void> task) {
        if (task.isSuccessful()) {
          LocationLog.i(TAG, "add geofence success！");
          setList(pendingIntent, GeoFenceData.getRequestCode(), GeoFenceData.returnList());
          GeoFenceData.createNewList();
        } else {
          // Get the status code for the error and log it using a user-friendly message.
          LocationLog.w(TAG, "add geofence failed : " + task.getException().getMessage());
        }
      }
    });
} catch (Exception e) {
  LocationLog.i(TAG, "add geofence error：" + e.getMessage());
}
private PendingIntent getPendingIntent() {
  Intent intent = new Intent(this, GeoFenceBroadcastReceiver.class);
  intent.setAction(GeoFenceBroadcastReceiver.ACTION_PROCESS_LOCATION);
  Log.d(TAG, "new request");
  GeoFenceData.newRequest();
  return PendingIntent.getBroadcast(this, GeoFenceData.getRequestCode(), intent,
    PendingIntent.FLAG_UPDATE_CURRENT);
}

• 触发消息推送。
  

在GeoFenceBroadcastReceiver的onReceive接收到围栏触发成功提示后发送推送通知，在通知栏接收通知并展示。
GeofenceData geofenceData = GeofenceData.getDataFromIntent(intent);
if (geofenceData != null) {
  int errorCode = geofenceData.getErrorCode();
  int conversion = geofenceData.getConversion();
  ArrayList<Geofence> list = (ArrayList<Geofence>) geofenceData.getConvertingGeofenceList();
  Location myLocation = geofenceData.getConvertingLocation();
  boolean status = geofenceData.isSuccess();
  sb.append("errorcode: " + errorCode + next);
  sb.append("conversion: " + conversion + next);
  if (list != null) {
    for (int i = 0; i < list.size(); i++) {
      sb.append("geoFence id :" + list.get(i).getUniqueId() + next);
    }
  }
  if (myLocation != null) {
    sb.append("location is :" + myLocation.getLongitude() + " " + myLocation.getLatitude() + next);
  }
  sb.append("is successful :" + status);
  LocationLog.i(TAG, sb.toString());
  Toast.makeText(context, "" + sb.toString(), Toast.LENGTH_LONG).show();
  //
  new PushSendUtils().netSendMsg(sb.toString());
}
