问题描述

我能够通过软件包管理器获取在我的code安装的应用程序的列表：

 公开的ArrayList＆LT; InstalledAppData＆GT; importInstalledAppsData（）{
        ArrayList的＆LT; InstalledAppData＆GT; APPLIST =新的ArrayList＆LT; InstalledAppData＆GT;（）;
        软件包管理系统pkgManager = getApplicationContext（）getPackageManager（）。
        清单＆LT; ApplicationInfo＆GT;包= getInstalledApplicationsList（pkgManager）;
        串DEVICEID = Util.getDeviceId（getApplicationContext（））;        对于（ApplicationInfo packageInfo：包）{
        字符串的packageName = packageInfo.packageName;
        串的appName =;
        字符串appFile = packageInfo.sourceDir;
        长installTime =新的文件（appFile）.lastModified（）;
        字符串状态=S;
        如果（（packageInfo.flags＆放大器; ApplicationInfo.FLAG_SYSTEM）== 1）{
                的appName =（字符串）pkgManager.getApplicationLabel（packageInfo）;
            }
            其他{
            的appName =（字符串）pkgManager.getApplicationLabel（packageInfo）;
        }
        InstalledAppData数据=新InstalledAppData（DEVICEID，的packageName，的appName，installTime，地位）;
            appList.add（数据）;
        }
        返回APPLIST;
    }
 

现在我想找出当前具有位置服务我enabled.How能做到这一点的手机上的所有安装的应用程序？
日Thnx提前

解决方案

  

我怎样才能做到这一点？

您不能。在Android SDK有没有办法为一个应用程序到另一个应用程序使用的谍的LocationManager 。

您可以注册 PASSIVE_PROVIDER 来看看的任何的恰好是请求位置更新，但你不能配合下来到一个特定的应用程序

I am able to fetch the list of the installed application in my code by package manager:

public ArrayList<InstalledAppData> importInstalledAppsData(){
        ArrayList<InstalledAppData> appList=new ArrayList<InstalledAppData>();
        PackageManager pkgManager=getApplicationContext().getPackageManager();
        List<ApplicationInfo> packages=getInstalledApplicationsList(pkgManager);
        String deviceId=Util.getDeviceId(getApplicationContext());

        for (ApplicationInfo packageInfo : packages) {
        String packageName=packageInfo.packageName;
        String appName="";
        String appFile = packageInfo.sourceDir;
        long installTime = new File(appFile).lastModified();
        String status="s";
        if ((packageInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 1) {
                appName = (String) pkgManager.getApplicationLabel(packageInfo);
            }
            else {
            appName = (String) pkgManager.getApplicationLabel(packageInfo);
        }                
        InstalledAppData data=new InstalledAppData(deviceId, packageName, appName, installTime, status);
            appList.add(data);


        }
        return appList;
    }

Now i want to identify all installed apps on the phone that currently have location services enabled.How can i do this? Thnx in advance

解决方案

How can i do this?

You can't. The Android SDK has no means for one application to spy on another application's use of LocationManager.

You can register for the PASSIVE_PROVIDER to see if anyone happens to be requesting location updates, but you cannot tie it down to a specific application.
