| 3243 | * <ul> |
| 3244 | * <li>@{code bw_penalty_box}: UIDs added to this chain do not have access (blacklist). |
| 3245 | * <li>@{code bw_happy_box}: UIDs added to this chain have access (whitelist), unless they're |
| 3246 | * also blacklisted. |
| 3247 | * <li>@{code bw_data_saver}: when enabled (through {@link #setRestrictBackground(boolean)}), |
| 3248 | * no UIDs other those whitelisted will have access. |
| 3249 | * <ul> |
| 3250 | * |
| 3251 | * <p>The @{code bw_penalty_box} and @{code bw_happy_box} are primarily managed through the |
| 3252 | * {@link #setUidPolicy(int, int)} and {@link #addRestrictBackgroundWhitelistedUid(int)} / |
| 3253 | * {@link #removeRestrictBackgroundWhitelistedUid(int)} methods (for blacklist and whitelist |
| 3254 | * respectively): these methods set the proper internal state (blacklist / whitelist), then call |
Felipe Leme | f082385 | 2016-06-08 13:43:08 -0700 | [diff] [blame] | 3255 | * this ({@link #updateRulesForDataUsageRestrictionsUL(int)}) to propagate the rules to |
Felipe Leme | 70c57c2 | 2016-03-29 10:45:13 -0700 | [diff] [blame] | 3256 | * {@link INetworkManagementService}, but this method should also be called in events (like |
| 3257 | * Data Saver Mode flips or UID state changes) that might affect the foreground app, since the |
| 3258 | * following rules should also be applied: |
| 3259 | * |
| 3260 | * <ul> |
| 3261 | * <li>When Data Saver mode is on, the foreground app should be temporarily added to |
| 3262 | * {@code bw_happy_box} before the @{code bw_data_saver} chain is enabled. |
| 3263 | * <li>If the foreground app is blacklisted by the user, it should be temporarily removed from |
| 3264 | * {@code bw_penalty_box}. |
| 3265 | * <li>When the app leaves foreground state, the temporary changes above should be reverted. |
| 3266 | * </ul> |
| 3267 | * |
| 3268 | * <p>For optimization, the rules are only applied on user apps that have internet access |
| 3269 | * permission, since there is no need to change the {@code iptables} rule if the app does not |
| 3270 | * have permission to use the internet. |
| 3271 | * |
