本文介绍如何在Android中通过pid获取对应应用的包名。示例代码展示了如何使用ActivityManager获取运行中的应用进程，并根据pid和uid匹配到对应的包名。

example :

if(packageNames.length >1){
int pid = Binder.getCallingPid();
int uid = Binder.getCallingUid();
ActivityManager am = (ActivityManager)mContext.getSystemService(mContext.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> runningApps = am.getRunningAppProcesses();
if (runningApps != null && runningApps.size() > 0) {
for (ActivityManager.RunningAppProcessInfo app : runningApps) {
if(app.pid == pid && app.uid ==uid){
packageNames[0] = app.processName;
break;
}
}
}
}

网络上的案例：

String callerPackage = getAppNameByPID(getContext(), Binder.getCallingPid());

private String getAppName(int pID)
{
    String processName = "";
    ActivityManager am = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE);
    List l = am.getRunningAppProcesses();
    Iterator i = l.iterator();
    PackageManager pm = this.getPackageManager();
    while(i.hasNext()) 
    {
          ActivityManager.RunningAppProcessInfo info = (ActivityManager.RunningAppProcessInfo)(i.next());
          try 
          { 
              if(info.pid == pID)
              {
                  CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(info.processName, PackageManager.GET_META_DATA));
                  //Log.d("Process", "Id: "+ info.pid +" ProcessName: "+ info.processName +"  Label: "+c.toString());
                  //processName = c.toString();
                  processName = info.processName;
              }
          }
          catch(Exception e) 
          {
                //Log.d("Process", "Error>> :"+ e.toString());
          }
   }
    return processName;
}

ActivityManagerService.java

@Override
public List<ApplicationInfo> getRunningExternalApplications() {
enforceNotIsolatedCaller("getRunningExternalApplications");
List<ActivityManager.RunningAppProcessInfo> runningApps = getRunningAppProcesses();
List<ApplicationInfo> retList = new ArrayList<ApplicationInfo>();
if (runningApps != null && runningApps.size() > 0) {
Set<String> extList = new HashSet<String>();
for (ActivityManager.RunningAppProcessInfo app : runningApps) {
if (app.pkgList != null) {
for (String pkg : app.pkgList) {
extList.add(pkg);
}
}
}

}
