1.2.2 最小值限制
frameworks/base/services/core/java/com/android/server/power/PowerManagerService.java
mMinimumScreenOffTimeoutConfig = resources.getInteger(com.android.internal.R.integer.config_minimumScreenOffTimeout); Math.max(timeout, mMinimumScreenOffTimeoutConfig);
1.3 属性值疑问 Settings.System.SCREEN_OFF_TIMEOUT
在设置屏幕超时代码代码中，最大值可以为“Long.MAX_VALUE”，属性设置Settings.System.putLong(context.getContentResolver(), SCREEN_OFF_TIMEOUT, value);，但是实质最大值只能是Integer.MAX_VALUE（2147483647）；该属性实质在fwk中是Integer保存，获取方式mScreenOffTimeoutSetting = Settings.System.getIntForUser(resolver, Settings.System.SCREEN_OFF_TIMEOUT, DEFAULT_SCREEN_OFF_TIMEOUT, UserHandle.USER_CURRENT);
frameworks/base/packages/SettingsProvider/src/android/provider/settings/validators/SettingsValidators.java 中 NON_NEGATIVE_INTEGER_VALIDATOR 检查非法值
private Long getMaxScreenTimeout(Context context) { if (context == null) { return Long.MAX_VALUE; } final DevicePolicyManager dpm = context.getSystemService(DevicePolicyManager.class); if (dpm == null) { return Long.MAX_VALUE; } mAdmin = RestrictedLockUtilsInternal.checkIfMaximumTimeToLockIsSet(context); if (mAdmin != null) { return dpm.getMaximumTimeToLock(null /* admin */, UserHandle.myUserId()); } return Long.MAX_VALUE; } private String getCurrentSystemScreenTimeout(Context context) { if (context == null) { return Long.toString(FALLBACK_SCREEN_TIMEOUT_VALUE); } else { return Long.toString(Settings.System.getLong(context.getContentResolver(), SCREEN_OFF_TIMEOUT, FALLBACK_SCREEN_TIMEOUT_VALUE)); } } private void setCurrentSystemScreenTimeout(Context context, String key) { try { if (context != null) { final long value = Long.parseLong(key); mMetricsFeatureProvider.action(context, SettingsEnums.ACTION_SCREEN_TIMEOUT_CHANGED, (int) value); Settings.System.putLong(context.getContentResolver(), SCREEN_OFF_TIMEOUT, value); } } catch (NumberFormatException e) { Log.e(TAG, "could not persist screen timeout setting", e); } }2、超时灭屏
2.1 锁定屏幕的超时
更新延时 mLockScreenTimeout 执行 mScreenLockTimeout
frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java
mLockScreenTimeout = Settings.System.getIntForUser(resolver,Settings.System.SCREEN_OFF_TIMEOUT, 0, UserHandle.USER_CURRENT); mHandler.postDelayed(mScreenLockTimeout, mLockScreenTimeout); class ScreenLockTimeout implements Runnable { Bundle options; @Override public void run() { synchronized (this) { if (localLOGV) Log.v(TAG, "mScreenLockTimeout activating keyguard"); if (mKeyguardDelegate != null) { mKeyguardDelegate.doKeyguardTimeout(options); } mLockScreenTimerActive = false; mLockNowPending = false; options = null; } } public void setLockOptions(Bundle options) { this.options = options; } }2.2 屏幕灭屏的超时
updateUserActivitySummaryLocked更新mUserActivitySummary的值，用户活动超时时调用updateUserActivitySummaryLocked，这里获取getScreenOffTimeoutLocked状态更新
frameworks/base/services/core/java/com/android/server/power/PowerManagerService.java
mScreenOffTimeoutSetting = Settings.System.getIntForUser(resolver, Settings.System.SCREEN_OFF_TIMEOUT, DEFAULT_SCREEN_OFF_TIMEOUT, UserHandle.USER_CURRENT); @GuardedBy("mLock") private long getScreenOffTimeoutLocked(long sleepTimeout, long attentiveTimeout) { long timeout = mScreenOffTimeoutSetting; if (isMaximumScreenOffTimeoutFromDeviceAdminEnforcedLocked()) { timeout = Math.min(timeout, mMaximumScreenOffTimeoutFromDeviceAdmin); } if (mUserActivityTimeoutOverrideFromWindowManager >= 0) { timeout = Math.min(timeout, mUserActivityTimeoutOverrideFromWindowManager); } if (sleepTimeout >= 0) { timeout = Math.min(timeout, sleepTimeout); } if (attentiveTimeout >= 0) { timeout = Math.min(timeout, attentiveTimeout); } return Math.max(timeout, mMinimumScreenOffTimeoutConfig); } private void handleUserActivityTimeout() { // runs on handler thread synchronized (mLock) { if (DEBUG_SPEW) { Slog.d(TAG, "handleUserActivityTimeout"); } mDirty |= DIRTY_USER_ACTIVITY; updatePowerStateLocked(); } } /** * Updates the value of mUserActivitySummary to summarize the user requested * state of the system such as whether the screen should be bright or dim. * Note that user activity is ignored when the system is asleep. * * This function must have no other side-effects. */ @GuardedBy("mLock") private void updateUserActivitySummaryLocked(long now, int dirty) { // Update the status of the user activity timeout timer. if ((dirty & (DIRTY_DISPLAY_GROUP_WAKEFULNESS | DIRTY_WAKE_LOCKS | DIRTY_USER_ACTIVITY | DIRTY_WAKEFULNESS | DIRTY_SETTINGS | DIRTY_ATTENTIVE)) == 0) { return; } mHandler.removeMessages(MSG_USER_ACTIVITY_TIMEOUT); final long attentiveTimeout = getAttentiveTimeoutLocked(); final long sleepTimeout = getSleepTimeoutLocked(attentiveTimeout); long screenOffTimeout = getScreenOffTimeoutLocked(sleepTimeout, attentiveTimeout); final long screenDimDuration = getScreenDimDurationLocked(screenOffTimeout); screenOffTimeout = getScreenOffTimeoutWithFaceDownLocked(screenOffTimeout, screenDimDuration); final boolean userInactiveOverride = mUserInactiveOverrideFromWindowManager; long nextTimeout = -1; boolean hasUserActivitySummary = false; for (int idx = 0; idx = powerGroup.getLastWakeTimeLocked()) { groupNextTimeout = lastUserActivityTime + screenOffTimeout - screenDimDuration; if (now = powerGroup.getLastWakeTimeLocked()) { groupNextTimeout = lastUserActivityTimeNoChangeLights + screenOffTimeout; if (now = 0) { final long anyUserActivity = Math.max(lastUserActivityTime, lastUserActivityTimeNoChangeLights); if (anyUserActivity >= powerGroup.getLastWakeTimeLocked()) { groupNextTimeout = anyUserActivity + sleepTimeout; if (now 0) { nextTimeout = Math.min(nextTimeout, nextProfileTimeout); } if (hasUserActivitySummary && nextTimeout >= 0) { scheduleUserInactivityTimeout(nextTimeout); } } private void scheduleUserInactivityTimeout(long timeMs) { final Message msg = mHandler.obtainMessage(MSG_USER_ACTIVITY_TIMEOUT); msg.setAsynchronous(true); mHandler.sendMessageAtTime(msg, timeMs); }3、永不休眠
-
- 在 PowerManagerService 和 PhoneWindowManager 处理
-
- 直接配置 Settings.System.SCREEN_OFF_TIMEOUT 为Integer.MAX_VALUE（ 2147483647 = 24.855 天 一般没有这么长时间亮屏待机 ），设置更长时间替换 Settings.System.SCREEN_OFF_TIMEOUT属性 VALIDATORS.put(System.SCREEN_OFF_TIMEOUT, NON_NEGATIVE_INTEGER_VALIDATOR) 中NON_NEGATIVE_INTEGER_VALIDATOR检测为NONE_NEGATIVE_LONG_VALIDATOR
