没有接显示屏，使用ardc导致。具体解决通过Android锁屏流程跟踪分析到：
frameworks\base\services\core\java\com\android\server\power\PowerManagerService.java
private void updatePowerStateLocked() { if (!mSystemReady || mDirty == 0) { return; } if (!Thread.holdsLock(mLock)) { Slog.wtf(TAG, "Power manager lock was not held when calling updatePowerStateLocked"); }
Trace.traceBegin(Trace.TRACE_TAG_POWER, "updatePowerState"); try { // Phase 0: Basic state updates. updateIsPoweredLocked(mDirty); updateStayOnLocked(mDirty); updateScreenBrightnessBoostLocked(mDirty);
// Phase 1: Update wakefulness. // Loop because the wake lock and user activity computations are influenced // by changes in wakefulness. final long now = SystemClock.uptimeMillis(); int dirtyPhase2 = 0; for (;;) { int dirtyPhase1 = mDirty; dirtyPhase2 |= dirtyPhase1; mDirty = 0;
updateWakeLockSummaryLocked(dirtyPhase1); updateUserActivitySummaryLocked(now, dirtyPhase1); if (!updateWakefulnessLocked(dirtyPhase1)) { break; } }
// Phase 2: Update display power state. boolean displayBecameReady = updateDisplayPowerStateLocked(dirtyPhase2);
// Phase 3: Update dream state (depends on display ready signal). updateDreamLocked(dirtyPhase2, displayBecameReady);
// Phase 4: Send notifications, if needed. finishWakefulnessChangeIfNeededLocked();
// Phase 5: Update suspend blocker. // Because we might release the last suspend blocker here, we need to make sure // we finished everything else first! updateSuspendBlockerLocked(); } finally { Trace.traceEnd(Trace.TRACE_TAG_POWER); } }
使用显示屏没有问题，希望可以和你遇到的问题一样！
