Android的系统设置数据存放在/data/data/com.android.providers.settings/databases/settings.db 中
-
adb shell settings get secure default_input_method -
adb shell settings get system screen_brightness_mode -
adb shell settings get system screen_brightness -
adb shell settings put system screen_brightness 150
数据库结构如下：
数据库中的默认数据在frameworks/base/packages/SettingsProvider/res/values/defaults.xml中定义
通过frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java对数据库结构及初始值进行初始化。
如果要在系统中添加默认设置，需要如下步骤（以带物理键盘的系统中默认打开软键盘为例）：
1、在defaults.xml中为新加的数据定义一个默认值
<integer name="show_ime_with_hard_keyboard">1</integer>
2、在DatabaseHelper.java中的loadSecureSettings(SQLiteDatabase db)方法中加入新字段的添加代码
loadStringSetting(stmt, Settings.Secure.SHOW_IME_WITH_HARD_KEYBOARD,
R.string.show_ime_with_hard_keyboar);
3、重新编译
Android L (5.1)及以前的版本
Settings参数保存在 /data/data/com.android.providers.settings/databases/settings.db里，里面有三个表global, system, secure.
通常这样查看数据
adb shell sqlite3 data/data/com.android.providers.settings/databases/settings.db “select * from secure”
或者adb pull settings.db到本地，然后用sqlite expert打开即可。
Android M (6.0)开始出现变化
不同用户放不同的路径下，如果没有创建新用户，则在/data/system/users/0下
settings_global.xml, settings_system.xml, settings_secure.xml
直接修改例子
adb shell settings get global captive_portal_server
adb shell settings put global captive_portal_server 0
<?xml version="1.0" encoding="utf-8"?>

frameworks中跟Setting默认值相关的几个文件
/frameworks/base/packages/SettingsProvider/res/values/defaults.xml
/frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java
在defaults.xml文件中定义了相关的值，DatabaseHelper.java会把相应的值读取出来保存到ContentProvider
下面就来看下defaults.xml中定义了哪些值
上 面的xml定义中String有一个属性translatable="false"表示多国语言时不需要进行翻译，这里就不对上面的定义一一解释，只对& lt;string name="def_location_providers_allowed" translatable="false">gps</string>进行分析
在DatabaseHelper.java中有一个函数来加载.xml中的字段
private void loadSecureSettings(SQLiteDatabase db) {
SQLiteStatement stmt = null;
try {
stmt = db.compileStatement("INSERT OR IGNORE INTO secure(name,value)"
+ " VALUES(?,?);");
loadSetting(stmt, Settings.Secure.LOCATION_PROVIDERS_ALLOWED,
mUtils.getStringValue(Settings.Secure.LOCATION_PROVIDERS_ALLOWED, R.string.def_location_providers_allowed));
String wifiWatchList = SystemProperties.get("ro.com.android.wifi-watchlist");
if (!TextUtils.isEmpty(wifiWatchList)) {
loadSetting(stmt, Settings.Secure.WIFI_WATCHDOG_WATCH_LIST, wifiWatchList);
}
// Don't do this. The SystemServer will initialize ADB_ENABLED from a
// persistent system property instead.
loadSetting(stmt, Settings.Secure.ADB_ENABLED, 1);
// Allow mock locations default, based on build
loadSetting(stmt, Settings.Secure.ALLOW_MOCK_LOCATION,
"1".equals(SystemProperties.get("ro.allow.mock.location")) ? 1 : 0);
loadSecure35Settings(stmt);
loadBooleanSetting(stmt, Settings.Secure.MOUNT_PLAY_NOTIFICATION_SND,
R.bool.def_mount_play_notification_snd);
loadBooleanSetting(stmt, Settings.Secure.MOUNT_UMS_AUTOSTART,
R.bool.def_mount_ums_autostart);
loadBooleanSetting(stmt, Settings.Secure.MOUNT_UMS_PROMPT,
R.bool.def_mount_ums_prompt);
loadBooleanSetting(stmt, Settings.Secure.MOUNT_UMS_NOTIFY_ENABLED,
R.bool.def_mount_ums_notify_enabled);
loadBooleanSetting(stmt, Settings.Secure.ACCESSIBILITY_SCRIPT_INJECTION,
R.bool.def_accessibility_script_injection);
loadStringSetting(stmt, Settings.Secure.ACCESSIBILITY_WEB_CONTENT_KEY_BINDINGS,
R.string.def_accessibility_web_content_key_bindings);
loadIntegerSetting(stmt, Settings.Secure.LONG_PRESS_TIMEOUT,
R.integer.def_long_press_timeout_millis);
loadBooleanSetting(stmt, Settings.Secure.TOUCH_EXPLORATION_ENABLED,
R.bool.def_touch_exploration_enabled);
loadBooleanSetting(stmt, Settings.Secure.ACCESSIBILITY_SPEAK_PASSWORD,
R.bool.def_accessibility_speak_password);
loadStringSetting(stmt, Settings.Secure.ACCESSIBILITY_SCREEN_READER_URL,
R.string.def_accessibility_screen_reader_url);
if (SystemProperties.getBoolean("ro.lockscreen.disable.default", false) == true) {
loadSetting(stmt, Settings.System.LOCKSCREEN_DISABLED, "1");
} else {
loadBooleanSetting(stmt, Settings.System.LOCKSCREEN_DISABLED,
R.bool.def_lockscreen_disabled);
}
loadBooleanSetting(stmt, Settings.Secure.SCREENSAVER_ENABLED,
com.android.internal.R.bool.config_dreamsEnabledByDefault);
loadBooleanSetting(stmt, Settings.Secure.SCREENSAVER_ACTIVATE_ON_DOCK,
com.android.internal.R.bool.config_dreamsActivatedOnDockByDefault);
loadBooleanSetting(stmt, Settings.Secure.SCREENSAVER_ACTIVATE_ON_SLEEP,
com.android.internal.R.bool.config_dreamsActivatedOnSleepByDefault);
loadStringSetting(stmt, Settings.Secure.SCREENSAVER_COMPONENTS,
com.android.internal.R.string.config_dreamsDefaultComponent);
loadStringSetting(stmt, Settings.Secure.SCREENSAVER_DEFAULT_COMPONENT,
com.android.internal.R.string.config_dreamsDefaultComponent);
loadBooleanSetting(stmt, Settings.Secure.ACCESSIBILITY_DISPLAY_MAGNIFICATION_ENABLED,
R.bool.def_accessibility_display_magnification_enabled);
loadFractionSetting(stmt, Settings.Secure.ACCESSIBILITY_DISPLAY_MAGNIFICATION_SCALE,
R.fraction.def_accessibility_display_magnification_scale, 1);
loadBooleanSetting(stmt,
Settings.Secure.ACCESSIBILITY_DISPLAY_MAGNIFICATION_AUTO_UPDATE,
R.bool.def_accessibility_display_magnification_auto_update);
loadBooleanSetting(stmt, Settings.Secure.USER_SETUP_COMPLETE,
R.bool.def_user_setup_complete);
mUtils.loadCustomSecureSettings(stmt);
} finally {
if (stmt != null) stmt.close();
}
}
在上面的代码中有
loadSetting(stmt, Settings.Secure.LOCATION_PROVIDERS_ALLOWED,
mUtils.getStringValue(Settings.Secure.LOCATION_PROVIDERS_ALLOWED, R.string.def_location_providers_allowed));去加载字符串，保存到数据库中，数据库名称为：
private static final String DATABASE_NAME = "settings.db";
static String dbNameForUser(final int userHandle) {
// The owner gets the unadorned db name;
if (userHandle == UserHandle.USER_OWNER) {
return DATABASE_NAME;
} else {
// Place the database in the user-specific data tree so that it's
// cleaned up automatically when the user is deleted.
File databaseFile = new File(
Environment.getUserSystemDirectory(userHandle), DATABASE_NAME);
return databaseFile.getPath();
}
}
public DatabaseHelper(Context context, int userHandle) {
super(context, dbNameForUser(userHandle), null, DATABASE_VERSION);
mContext = context;
mUserHandle = userHandle;
}
来看下是如何读取ContentProvider中的数据，在Setting中就可以使用getContentResolver()去查询对应的字段
当然并不是所有的默认值都是通过读取defaults.xml的，也有的是在DatabaseHelper.java中直接设置
如loadSetting(stmt, Settings.Secure.ADB_ENABLED, 1); 这个ADB Debugging开关就是直接在数据库文件中写入的。
关于USB Debugging 开关也可以在systemui的systemui/usb/StorageNotification.java文件中去设置，可以判断是否有IMEI号
分析代码时如果发现在defaults.xml找不到这一项就直接在DatabaseHelper.java文件中查找。
1，是否有默认值
在寻找一个开关的默认值时，首先要明白一点，该开关是否存在默认值，以及该开关状态是否有状态保存（一般状态存储在settings的db中）。 判断条件： 在reboot（重启）之后开关状态仍旧保存或者是在reset（恢复出厂设置）之后开关状态恢复到默认的，才能找到默认值。 在reboot之后开关状态仍旧保存的，表示状态存储在了db中。 在reset之后开关状态恢复默认的，表示状态有一个默认值。
比如像wiif开关，蓝牙开关，gps开关等，都有默认值，并且状态值都在db中保存。
至于像WiFi热点开关这种在reboot之后，状态没有保存，那么你就别白费力气来找他的默认值或者状态存储值了
2，修改默认值
大部分的开关状态都存储在了SettingProvider的db中，与状态值相关的有三个文件
- /frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java：该文件中对状态值进行存储
- /frameworks/base/packages/SettingsProvider/res/values/defaults.xml：定义了开关状态的默认值
- /frameworks/base/core/java/android/provider/Settings.java：定义了各开关状态默认值存储时对应的key
接下里看都有什么默认值
