使用Google Play服务版本11.6或更高版本,这将大大提高Geofencing的速度和精度。确保在应用程序级别中使用最新版本的Google Play服务库。
通过合理配置Geofence添加程序来优化应用程序的性能。合理设置地理围栏半径以减少检查的距离,同时将围栏数量限制在较少的数量。以下是一个参考代码示例:
public void addGeofence(Geofence geofence) { if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) { return; }
// Get the PendingIntent for the geofence.
Intent intent = new Intent(this, GeofenceTransitionIntentService.class);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
// Create a new GeofencingRequest, add the geofence, and call the GoogleApiClient
// to add the request.
GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER);
builder.addGeofence(geofence);
GeofencingRequest request = builder.build();
LocationServices.GeofencingApi.addGeofences(mGoogleApiClient, request,
pendingIntent).setResultCallback(this);
}
总之,要优化Android上Geofencing的速度,您可以使用最新版本的Google Play服务库,优化Geofence添加程序并选择合适的定位库。
