Question

这个异步任务似乎陷入僵局，等待着自己。

"AsyncTask #1" prio=5 tid=17 WAIT
  | group="main" sCount=1 dsCount=0 obj=0x423f0540 self=0x50af12d0
  | sysTid=22185 nice=10 sched=0/0 cgrp=apps/bg_non_interactive handle=1353653152
  | schedstat=( 0 0 0 ) utm=0 stm=0 core=1
  at java.lang.Object.wait(Native Method)
  - waiting on <0x424c3f48> (a java.lang.VMThread) held by tid=17 (AsyncTask #1)

  at java.lang.Thread.run(Thread.java:856)

关于为什么会发生这种情况的任何想法？我通过execute（）调用了我的asyncTask;多个AsyncTasks在我的应用程序中并行运行。

这不是僵局。线程“停放”等待运行。它正在等待拥有的内部锁。看到线程处于这种状态是正常的。
