设定系统属性的默认值的位置:
frameworks/base/+/440853/4/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java
frameworks/base/core/res/res/values/config.xml
frameworks/base/core/res/res/values/symbols.xml
?
这边的例子就是新增一个字段去设定默认值
sysmbols.xml config.xml里 定义新的字段:
DatabaseHelper.java:
private void loadSecureSettings(SQLiteDatabase db) {
SQLiteStatement stmt = null;
try {
stmt = db.compileStatement("INSERT OR IGNORE INTO secure(name,value)"
+ " VALUES(?,?);");
// Don't do this. The SystemServer will initialize ADB_ENABLED from a
// persistent system property instead.
//loadSetting(stmt, Settings.Secure.ADB_ENABLED, 0);
// 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.ACCESSIBILITY_SPEAK_PASSWORD,
R.bool.def_accessibility_speak_password);
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);
}
if (ZebraUtils.isZebra().orElse(false) && ZebraUtils.getDefScreenSaverStart().orElse(-1) == 0){
loadBooleanSetting(stmt, Settings.Secure.SCREENSAVER_ENABLED,
com.android.internal.R.bool.config_dreamsEnabledByDefault_never);
} else {
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_DEFAULT_COMPONENT,
com.android.internal.R.string.config_dreamsDefaultComponent);
if (ZebraUtils.isDeviceMoneypenny().orElse(false)) {
loadStringSetting(stmt, Settings.Secure.SCREENSAVER_COMPONENTS,
com.android.internal.R.string.config_dreamsDefaultComponentPS30);
}
}
