public static List<String> getWhiteAppProcessList() {
List<String> list = new ArrayList();
String sizeKey = "persist.xxx.aliveapps_s";
String valKey = "persist.xxx.aliveapps_";
int size = 0;
try
{
size = Integer.parseInt(SystemProperties.get(sizeKey));
}
catch(Exception e)
{
}
if(size>0)
{
for(int i=0;i<size;i++)
{
list.add(SystemProperties.get(valKey+i));
}
}
return list;
}
public static void setWhiteAppProcessList(List<String> whiteAppProcessList) {
if(whiteAppProcessList==null || whiteAppProcessList.size()==0)
{
whiteAppProcessList = new ArrayList();
}
String sizeKey = "persist.xxx.aliveapps_s";
String valKey = "persist.xxx.aliveapps_";
int orgSize = 0;
try
{
orgSize = Integer.parseInt(SystemProperties.get(sizeKey));
}
catch(Exception e)
{
}
if (orgSize > 0) {
for(int i=0;i<orgSize;i++)
{
SystemProperties.set(valKey+i,"");
}
}
int size = whiteAppProcessList.size();
SystemProperties.set(sizeKey,String.valueOf(size));
for(int i=0;i<size;i++)
{
SystemProperties.set(valKey+i,whiteAppProcessList.get(i));
}
}
