我正在开发一个带有一些线程的程序,有时我会收到以下错误消息:
11-03 18:58:06.047: I/dalvikvm(3587): threadid=15: stack overflow on call to Ljava/lang/ref/FinalizerReference;.<init>:VLL
11-03 18:58:06.047: I/dalvikvm(3587): method requires 12+20+12=44 bytes, fp is 0x591ad314 (20 left)
11-03 18:58:06.047: I/dalvikvm(3587): expanding stack end (0x591ad300 to 0x591ad000)
11-03 18:58:06.047: I/dalvikvm(3587): Shrank stack (to 0x591ad300, curFrame is 0x591ad328)
我使用此代码输出我所有的活动线程:
Set<Thread> threadSet = Thread.getAllStackTraces().keySet();
Thread[] threadArray = threadSet.toArray(new Thread[threadSet.size()]);
for(int i=0;i<threadArray.length;i++){
Log.e("Threadtest", threadArray[i].getName()+"|"+ threadArray[i].getClass()+"|"+ threadArray[i].getId());
}
这是输出:

当我知道错误发生在哪个线程时,这将对我有很大帮助。
最好的问候马库斯
