| 1172 | * <p> |
| 1173 | * This is a temporary hack that allows an activity to "cover up" any |
| 1174 | * display glitches that happen during the activity's startup |
| 1175 | * sequence. (Specifically, this API was added to work around a |
| 1176 | * cosmetic bug in the "incoming call" sequence, where the lock screen |
| 1177 | * would flicker briefly before the incoming call UI became visible.) |
| 1178 | * TODO: There ought to be a more elegant way of doing this, |
| 1179 | * probably by having the PowerManager and ActivityManager |
| 1180 | * work together to let apps specify that the screen on/off |
| 1181 | * state should be synchronized with the Activity lifecycle. |
| 1182 | * <p> |
| 1183 | * Note that calling preventScreenOn(true) will NOT turn the screen |
| 1184 | * off if it's currently on. (This API only affects *future* |
| 1185 | * acquisitions of full wake locks.) |
| 1186 | * But calling preventScreenOn(false) WILL turn the screen on if |
| 1187 | * it's currently off because of a prior preventScreenOn(true) call. |
| 1188 | * <p> |
| 1189 | * Any call to preventScreenOn(true) MUST be followed promptly by a call |
| 1190 | * to preventScreenOn(false). In fact, if the preventScreenOn(false) |
| 1191 | * call doesn't occur within 5 seconds, we'll turn the screen back on |
| 1192 | * ourselves (and log a warning about it); this prevents a buggy app |
| 1193 | * from disabling the screen forever.) |
| 1194 | * <p> |
| 1195 | * TODO: this feature should really be controlled by a new type of poke |
| 1196 | * lock (rather than an IPowerManager call). |
