三十八、判断服务是否运行及定位问题

    /**
     * 判断服务是否正在运行
     * 
     * @param context
     * @param className 判断的服务名字：包名+类名
     * @return true在运行 false 不在运行
     */
    public static boolean isServiceRunning(Context context, String className) {
        boolean isRunning = false;
        
        ActivityManager activityManager = (ActivityManager) context
                .getSystemService(Context.ACTIVITY_SERVICE);
        //获取所有的服务
        List<ActivityManager.RunningServiceInfo> services= activityManager.getRunningServices(Integer.MAX_VALUE);
        if(services!=null&&services.size()>0){
            for(ActivityManager.RunningServiceInfo service : services){
                if(className.equals(service.service.getClassName())){
                    isRunning=true;
                    break;
                }
            }
        }

        return isRunning;
    }

                   

               

在android开发中，经常会使用locationManager.getLastKnownLocation()定时获取经纬度，在不同真机测试中有的可以获取有的不可以获取，为了解决不同手机的兼容下，请用如下代码

    public static Location getLocation(LocationManager locationManager, LocationListener locationListener) {
        Location location=null;
         
        location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
        if(location==null){
            location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
            locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
        }

        return location;
    }
