Bug:java.lang.IllegalStateException

使用迭代的时候，出现了java.lang.IllegalStateException

代码：

 for ( TaskInfo info : userTaskInfos ) {
                 if ( info.isChecked() ) {
                     am.killBackgroundProcesses(info.getPackageName());
                     if ( getPackageName().equals(info.getPackageName()) ) {
                         continue;
                     }
                     avaliMem = avaliMem + info.getMemSize();
                     runningTaskCount = runningTaskCount - 1;
                     userTaskInfos.remove(info)

                 }
             }

原因：迭代的时候，不能操作数据。

解决办法：

 List< TaskInfo > removeTasks = new ArrayList<>();

             for ( TaskInfo info : userTaskInfos ) {
                 if ( info.isChecked() ) {
                     am.killBackgroundProcesses(info.getPackageName());
                     if ( getPackageName().equals(info.getPackageName()) ) {
                         continue;
                     }
                     avaliMem = avaliMem + info.getMemSize();
                     runningTaskCount = runningTaskCount - 1;
                     removeTasks.add(info);
                 }
             }
             userTaskInfos.removeAll(removeTasks);
