Android开发卡死

Question

现象描述：屏幕卡死，无法操作 版本：5.1.用于仪器检测操作 内容描述：新公司接收之前的项目，用公司的板子开发的，加入了anr-watchdog。死机后重启，导出了traces文件。想知道是什么原因，然后分析逻辑过程，不胜感激。 错误相关：{"@type":"com.github.anrwatchdog.ANRError","cause":{"@type":"com.github.anrwatchdog.ANRError$$$_Thread","cause":{"@type":"com.github.anrwatchdog.ANRError$$$_Thread","cause":{"@type":"com.github.anrwatchdog.ANRError$$$_Thread","cause":{"@type":"com.github.anrwatchdog.ANRError$$$_Thread","cause":{"@type":"com.github.anrwatchdog.ANRError$$$_Thread","cause":{"@type":"com.github.anrwatchdog.ANRError$$$_Thread","cause":{"@type":"com.github.anrwatchdog.ANRError$$$_Thread","localizedMessage":"|ANR-WatchDog| (state = RUNNABLE)","message":"|ANR-WatchDog| (state = RUNNABLE)","stackTrace":[{"className":"dalvik.system.VMStack","fileName":"VMStack.java","lineNumber":-2,"methodName":"getThreadStackTrace","nativeMethod":true},{"className":"java.lang.Thread","fileName":"Thread.java","lineNumber":580,"methodName":"getStackTrace","nativeMethod":false},{"className":"java.lang.Thread","fileName":"Thread.java","lineNumber":522,"methodName":"getAllStackTraces","nativeMethod":false},{"className":"com.github.anrwatchdog.ANRError","fileName":"ANRError.java","lineNumber":77,"methodName":"New","nativeMethod":false},{"className":"com.github.anrwatchdog.ANRWatchDog","fileName":"ANRWatchDog.java","lineNumber":273,"methodName":"run","nativeMethod":false}],"suppressed":[]},"localizedMessage":"ReferenceQueueDaemon (state = WAITING)","message":"ReferenceQueueDaemon (state = WAITING)","stackTrace":[{"className":"java.lang.Object","fileName":"Object.java","lineNumber":-2,"methodName":"wait","nativeMethod":true},{"className":"java.lang.Daemons$ReferenceQueueDaemon","fileName":"Daemons.java","lineNumber":134,"methodName":"run","nativeMethod":false},{"className":"java.lang.Thread","fileName":"Thread.java","lineNumber":818,"methodName":"run","nativeMethod":false}],"suppressed":[]},"localizedMessage":"HeapTrimmerDaemon (state = WAITING)","message":"HeapTrimmerDaemon (state = WAITING)","stackTrace":[{"className":"java.lang.Object","fileName":"Object.java","lineNumber":-2,"methodName":"wait","nativeMethod":true},{"className":"java.lang.Daemons$HeapTrimmerDaemon","fileName":"Daemons.java","lineNumber":311,"methodName":"run","nativeMethod":false},{"className":"java.lang.Thread","fileName":"Thread.java","lineNumber":818,"methodName":"run","nativeMethod":false}],"suppressed":[]},"localizedMessage":"GCDaemon (state = WAITING)","message":"GCDaemon (state = WAITING)","stackTrace":[{"className":"java.lang.Object","fileName":"Object.java","lineNumber":-2,"methodName":"wait","nativeMethod":true},{"className":"java.lang.Daemons$GCDaemon","fileName":"Daemons.java","lineNumber":344,"methodName":"run","nativeMethod":false},{"className":"java.lang.Thread","fileName":"Thread.java","lineNumber":818,"methodName":"run","nativeMethod":false}],"suppressed":[]},"localizedMessage":"FinalizerWatchdogDaemon (state = WAITING)","message":"FinalizerWatchdogDaemon (state = WAITING)","stackTrace":[{"className":"java.lang.Object","fileName":"Object.java","lineNumber":-2,"methodName":"wait","nativeMethod":true},{"className":"java.lang.Daemons$FinalizerWatchdogDaemon","fileName":"Daemons.java","lineNumber":240,"methodName":"waitForObject","nativeMethod":false},{"className":"java.lang.Daemons$FinalizerWatchdogDaemon","fileName":"Daemons.java","lineNumber":212,"methodName":"run","nativeMethod":false},{"className":"java.lang.Thread","fileName":"Thread.java","lineNumber":818,"methodName":"run","nativeMethod":false}],"suppressed":[]},"localizedMessage":"FinalizerDaemon (state = WAITING)","message":"FinalizerDaemon (state = WAITING)","stackTrace":[{"className":"java.lang.Object","fileName":"Object.java","lineNumber":-2,"methodName":"wait","nativeMethod":true},{"className":"java.lang.Object","fileName":"Object.java","lineNumber":422,"methodName":"wait","nativeMethod":false},{"className":"java.lang.ref.ReferenceQueue","fileName":"ReferenceQueue.java","lineNumber":101,"methodName":"remove","nativeMethod":false},{"className":"java.lang.ref.ReferenceQueue","fileName":"ReferenceQueue.java","lineNumber":72,"methodName":"remove","nativeMethod":false},{"className":"java.lang.Daemons$FinalizerDaemon","fileName":"Daemons.java","lineNumber":174,"methodName":"run","nativeMethod":false},{"className":"java.lang.Thread","fileName":"Thread.java","lineNumber":818,"methodName":"run","nativeMethod":false}],"suppressed":[]},"localizedMessage":"main (state = NEW)","message":"main (state = NEW)","stackTrace":[],"suppressed":[]},"duration":5000,"localizedMessage":"Application Not Responding for at least 5000 ms.","message":"Application Not Responding for at least 5000 ms.","stackTrace":[],"suppressed":[]}

补充下。程序是主应用，然后长时间待机，在service启动线程通过串口和下位机每5秒发送接收数据。大概过几个小时就会死机
