Added the "never sleep" function in Android display settings. android display settings

Set def_screen_off_timeout to-1 in frameworks \ base \ packages \ SettingsProvider \ res \ values \ defaults. xml, that is
<Integer name = "def_screen_off_timeout">-1 </integer>
Then modify alps \ packages \ apps \ Settings \ res \ values \ arrays. xml:

 <!-- Display settings.  The delay in inactivity before the screen is turned off. These are shown ain a list dialog. -->    <string-array name="screen_timeout_entries">        <item>15 seconds</item>        <item>30 seconds</item>        <item>1 minute</item>        <item>2 minutes</item>        <item>10 minutes</item>        <item>30 minutes</item>        <item>never</item>    </string-array>     <!-- Do not translate. -->   <string-array  name="screen_timeout_values" translatable="false">        <!-- Do not translate. -->        <item>15000</item>        <!-- Do not translate. -->        <item>30000</item>        <!-- Do not translate. -->        <item>60000</item>        <!-- Do not translate. -->        <item>120000</item>        <!-- Do not translate. -->        <item>600000</item>        <!-- Do not translate. -->        <item>1800000</item>         <item>-1</item>    </string-array>

Next, modify arrays. xml in the value folder of the comparison language and the translation corresponding to screen_timeout_entries. You don't need to worry about the msgid, but google is used to indicate that it is his own resource. Simply add <item> "never sleep" </item>.

Then the code changes:

Frameworks/base/services/java/com/android/server/power/PowerManagerService. java

private void updateUserActivitySummaryLocked(long now, int dirty) {..... //change code here ==============                      Slog.d(TAG,"mScreenOffTimeoutSetting ="+mScreenOffTimeoutSetting);                      //if (mUserActivitySummary != 0 ) {                if (mUserActivitySummary != 0 && mScreenOffTimeoutSetting > 0) {//change code here  end ==============                    Message msg = mHandler.obtainMessage(MSG_USER_ACTIVITY_TIMEOUT);                    msg.setAsynchronous(true);                    mHandler.sendMessageAtTime(msg, nextTimeout);                }
