【AndroidFramework】【EMMC拷机】混合拷机时盒子待机

问题结论

暂时确定为误按键,不是故障。问题关闭。后续完全保证无按键(物理隔离)情况下如果出现待机,请反馈。

问题描述

【EMMC拷机】混合拷机时盒子待机---新版本引入
EMMC:东芝THGBMFG6C1LBAIL 容量为8GB
【故障描述】
1,拷机10台,全部杀了遥控器,拷机播放13H后发现一台出现问题
2,混合拷机时盒子待机

分析详细

结果显示,待机只发生在最后一份日志,并且显示为power button,结果基本明晰。接下来,
1.确认框架代码,什么情况下会出现该打印(遥控器按到了?其他未知原因调用到了?)
2.是不是碰到盒子上‘待机按钮’引起的
3.是不是什么apk调用了自动待机的接口?

跳转到打印处,调用的方法,梳理逻辑。

// This method is called goToSleep for historical reasons but we actually start
    // dozing before really going to sleep.

                    break;
            }

            mLastSleepTime = eventTime;
            mSandmanSummoned = true;
            setWakefulnessLocked(WAKEFULNESS_DOZING, reason);

            // Report the number of wake locks that will be cleared by going to sleep.
            int numWakeLocksCleared = 0;
            final int numWakeLocks = mWakeLocks.size();
            for (int i = 0; i < numWakeLocks; i++) {
                final WakeLock wakeLock = mWakeLocks.get(i);
                switch (wakeLock.mFlags & PowerManager.WAKE_LOCK_LEVEL_MASK) {
                    case PowerManager.FULL_WAKE_LOCK:
                    case PowerManager.SCREEN_BRIGHT_WAKE_LOCK:
                    case PowerManager.SCREEN_DIM_WAKE_LOCK:
                        numWakeLocksCleared += 1;
                        break;
                }
            }
            EventLogTags.writePowerSleepRequested(numWakeLocksCleared);

            // Skip dozing if requested.
            if ((flags & PowerManager.GO_TO_SLEEP_FLAG_NO_DOZE) != 0) {
                reallyGoToSleepNoUpdateLocked(eventTime, uid);
            }
        } finally {
            Trace.traceEnd(Trace.TRACE_TAG_POWER);
        }
        return true;
    }

由以上代码可见,待机是由于power按键。不是由于某些应用程序调用。
