我有一个类的问题,log cat在运行时返回此错误

12-05 23:19:18.299: E/AndroidRuntime(15460): Caused by: java.lang.IllegalArgumentException: provider==null

代码是

     /************************************************************************************
     * 
     * Creamos un location manager, le establecemos unos criterios minimos para encontra
     * 
     ***********************************************************************************/
    LocationManager locManager = (LocationManager)getSystemService(LOCATION_SERVICE);
    Criteria criterio = new Criteria();
    criterio.setAccuracy(Criteria.ACCURACY_COARSE);
    String mejorProvider = locManager.getBestProvider(criterio, true);

        //Obtenemos la última posición conocida
        final Location loc = locManager.getLastKnownLocation(mejorProvider);
        latitud = loc.getLatitude();
        longitud= loc.getLongitude();

        //Me centro en el …

我有这样的文件:

{
    "_id" : ObjectId("53340d07d6429d27e1284c77"),
    "worktypes" : [ 
        {
            "name" : "Pompas",
            "works" : [ 
                {
                    "name" : "work 1",
                    "code" : "0001"
                }
            ]
        },
        {
            "name" : "Pompas "",
            "works" : [ 
                {
                    "name" : "work 2",
                    "code" : "0002"
                }
            ]
        }
    ]
}

我做了一个查询,只获取本文档的工作类型之一的作品,这是查询:

db.categories.find({$and: [
        { "_id": ObjectId('53340d07d6429d27e1284c77')},
        {"worktypes.name": "Pompas"}
    ]},{"worktypes.works.$":1})

但我得到了

    {
    "_id" : ObjectId("53340d07d6429d27e1284c77"),
    "worktypes" : [ 
        {
            "name" : "Pompas",
            "works" : [ 
                {
                    "name" : "work 1",
                    "code" : "0001"
                } …

我有这个代码:

#!/bin/bash
PIDS=$(ls -la /proc | awk '{print $9}' | grep "^[0-9]*$")
PIDLIST=$(echo $PIDS | tr "" "\n")
counter=0
for PID in $PIDLIST; do
  KERNEL[$counter]=$(cat "/proc/$PID/stat" | awk '{print $14 }')
  counter=$((counter + 1))
done

我试图cat "/proc/$PID/stat" | awk '{print $14 }'在一个指定的KERNEL数组中保存命令的内容,给出一个计数器的位置.

我有这个错误:

mitop.sh: 8: mitop.sh: KERNEL[0]=26: not found

我做错了什么？

sistemas@DyASO:~$ bash --version

我,我正在做一个模式正则表达式,以检查一个字符串是否:

digit.digit.digit是这样的:

1.1.1
0.20.2
58.55541.5221

在java中我使用这个:

private static Pattern pattern = Pattern.compile("\\d*.\\d*.\\d*", Pattern.CASE_INSENSITIVE);

但如果我通过20.20.在比赛中给我回报.

什么是grond？
