Android Settings和SettingsProvider源码分析与修改
习惯了，看源码从AndroidManifest文件看起，先对工程有个大致的认识。
Settings也是经常需要改动的部分之一，包名：com.android.settings，工程名：Settings，代码量也不小，慢慢啃。
4.4 SDK的Settings的AndroidManifest文件有2100+行，用ADT格式化后变成2600+行，好吧。
首先是权限，直接把注释写在里面了：
Setting显示开发者选项的逻辑
默认User版本没有“开发者选项”，我们可以通过点击版本号7次来显示开发者模式，今天来看下代码中是如何处理的：
首先是packages/apps/Settings/src/com/android/settings/Settings.java的初始化处理：
布尔值showDev是否默认显示“开发者选项”：
final boolean showDev = mDevelopmentPreferences.getBoolean(
DevelopmentSettings.PREF_SHOW,
android.os.Build.TYPE.equals("eng"));如果想让开发者选项默认显示，不需要点击7次版本号，可直接将showDev置为true即可：
final boolean showDev = true; 如果showDev为false，则在如下代码中隐藏“开发者选项”：
if (id == R.id.development_settings) {
if (!showDev) {
target.remove(i);
}
} 代码路径：packages/apps/Settings/src/com/android/settings/DeviceInfoSettings.java
首先是定义点击次数：
static final int TAPS_TO_BE_A_DEVELOPER = 7;点击版本号的处理逻辑，若mDevHitCountdown小于0，则表示”开发者选项“已经显示，参考Resume函数的处理：
if (preference.getKey().equals(KEY_BUILD_NUMBER)) {
// Don't enable developer options for secondary users.
if (UserHandle.myUserId() != UserHandle.USER_OWNER) return true;
if (mDevHitCountdown > 0) {
if (mDevHitCountdown == 1) {
if (super.ensurePinRestrictedPreference(preference)) {
return true;
}
}
mDevHitCountdown--;
if (mDevHitCountdown == 0) {
getActivity().getSharedPreferences(DevelopmentSettings.PREF_FILE,
Context.MODE_PRIVATE).edit().putBoolean(
DevelopmentSettings.PREF_SHOW, true).apply();
if (mDevHitToast != null) {
mDevHitToast.cancel();
}
mDevHitToast = Toast.makeText(getActivity(), R.string.show_dev_on,
Toast.LENGTH_LONG);
mDevHitToast.show();
} else if (mDevHitCountdown > 0
&& mDevHitCountdown < (TAPS_TO_BE_A_DEVELOPER-2)) {
if (mDevHitToast != null) {
mDevHitToast.cancel();
}
mDevHitToast = Toast.makeText(getActivity(), getResources().getQuantityString(
R.plurals.show_dev_countdown, mDevHitCountdown, mDevHitCountdown),
Toast.LENGTH_SHORT);
mDevHitToast.show();
}
} else if (mDevHitCountdown < 0) {
if (mDevHitToast != null) {
mDevHitToast.cancel();
}
mDevHitToast = Toast.makeText(getActivity(), R.string.show_dev_already,
Toast.LENGTH_LONG);
mDevHitToast.show();
}
} Resume函数：
@Override
public void onResume() {
super.onResume();
PreferenceGroup parentPreference = getPreferenceScreen();
mDevHitCountdown = getActivity().getSharedPreferences(DevelopmentSettings.PREF_FILE,
Context.MODE_PRIVATE).getBoolean(DevelopmentSettings.PREF_SHOW,
android.os.Build.TYPE.equals("eng")) ? -1 : TAPS_TO_BE_A_DEVELOPER;
mDevHitToast = null;
}Setting的默认初始配置
中初始化才会生效：

当然还有mtk_default.xml
修改完成后，在
frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java
中的 private void loadGlobalSettings(SQLiteDatabase db) { ... ... }函数中增加初始化数据库的值：
然后执行：
./mk -t mm frameworks/base/packages/SettingsProvider/
生成目录：
out/target/product/esky82_tb_cn_kk/system/priv-app/SettingsProvider.apk
删除设置中情景模式的震动选项（会议模式和户外模式）
packages/apps/Settings/res/xml/audioprofile_settings.xml
//pref = (AudioProfilePreference) findPreference(MEETING_PREF_KEY);
//pref.setOnSettingsClickListener(mProfileSettingListener);
//pref = (AudioProfilePreference) findPreference(OUTDOOR_PREF_KEY);
//pref.setOnSettingsClickListener(mProfileSettingListener);if (!SystemProperties.get("ro.project.target").equals("es706")) {
// Do nothing
} else {
pref = (AudioProfilePreference) findPreference(MEETING_PREF_KEY);
pref.setOnSettingsClickListener(mProfileSettingListener);
pref = (AudioProfilePreference) findPreference(OUTDOOR_PREF_KEY);
pref.setOnSettingsClickListener(mProfileSettingListener);
} // mVibrat = (CheckBoxPreference) findPreference(KEY_VIBRATE);
... ...
// mVibrat.setEnabled(false);if (!isSmsCapable()) {
// parent.removePreference(mVibrat);
}
private void updatePreference() {
// mVibrat.setChecked(mProfileManager.getVibrationEnabled(mKey));// if (mVibrat != null) {
// final String name = AudioProfileManager.getVibrationKey(mKey);
// Xlog.d(TAG,"name " + name);
// String vibrateEnabled = Settings.System.getString(
// getContentResolver(), name);
// if (vibrateEnabled != null) {
// mVibrat.setChecked("true"
// .equals(vibrateEnabled));
// Xlog.d(TAG,
// "vibrate setting is "
// + "true".equals(vibrateEnabled));
// }
//
// }public boolean onPreferenceTreeClick(PreferenceScreen preferenceScreen,
Preference preference) {
Xlog.d(TAG, "Key :" + preference.getKey());
// if ((preference.getKey()).equals(KEY_VIBRATE)) {
// boolean isVibrate = mVibrat.isChecked();
// Xlog.d(TAG, "set vibrate" + isVibrate);
// mProfileManager.setVibrationEnabled(mKey, isVibrate);
// } else 首先在frameworks\base\packages\SettingsProvider\res\values\defaults.xml中设置def_screen_off_timeout为-1，即
然后修改alps\packages\apps\Settings\res\values\arrays.xml:
- 15 seconds
- 30 seconds
- 1 minute
- 2 minutes
- 10 minutes
- 30 minutes
- never
- 15000
- 30000
- 60000
- 120000
- 600000
- 1800000
- -1
接着修改对比语言value文件夹下的arrays.xml, 修改screen_timeout_entries对应的翻译。不用管那个msgid，只是google用来表示是他自己的资源而已，直接添加
然后是代码的改动：
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);
}Google默认的PackageManager，会读取应用AndroidManifest.xml的对应定义
installLocation规则如下：
1.如果没有定义安装位置，表示安装在手机内存上；
2.android:installLocation ="auto" :先查看手机内存是否足够，如果够就安装在手机内存上，不够就安装在T 卡上；
3.android:installLocation = "internalOnly":表示安装在手机内存上；
4.android:installLocation = "preferExternal":表示安装在 T 卡上；
如何在设置中增加“选取应用安装位置”的功能，让用户选择默认的安装位置？
修改如下文件：frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java
将
loadSetting(stmt, Global.SET_INSTALL_LOCATION, 0);改为：
loadSetting(stmt, Secure.SET_INSTALL_LOCATION, 1);并将
loadSetting(stmt, Settings.Secure.SET_INSTALL_LOCATION, 0);loadSetting(stmt, Settings.Secure.SET_INSTALL_LOCATION, 1);这样修改之后，在设置>应用中会出现“选取应用安装位置”的功能，不过无论在这里选择什么，对于应用中AndroidManifest.xml文件中声明
android:installLocation = "internalOnly"默认输入法勾选多国语言，并默认其中一种语言
1.首先在设备上调整输入法
设置>语言输入法>Android键盘(AOSP)，在输入语言里勾选要选择的语言，比如选“英语(美国)”和“西班牙文”两种：
2.选择系统输入法的默认语言（默认为两种语言中的“西班牙文”）
打开一个能能调出输入法的应用，下拉通知栏里，“选择输入法”调整为“西班牙文”
3.查看Setting数据库文件
adb pull data/data/com.android.providers.settings/databases/settings.db C:\
打开Secure表，查看default_input_method，enabled_input_methods和selected_input_method_subtype三个字段内容，并记录：
default_input_method com.android.inputmethod.latin/.LatinIME
enabled_input_methods com.android.inputmethod.latin/.LatinIME;816242702;-921088104
selected_input_method_subtype 816242702
4.修改SettingsProvider文件
frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java
将函数private void loadSecureSettings(SQLiteDatabase db) 中的以下两行（注意是loadSecureSettings函数，不是loadSystemSettings）：
loadSetting(stmt, Settings.Secure.ENABLED_INPUT_METHODS, defaultIme);
loadSetting(stmt, Settings.Secure.DEFAULT_INPUT_METHOD, defaultIme);修改为以下三行：
loadSetting(stmt, Settings.Secure.ENABLED_INPUT_METHODS,"com.android.inputmethod.latin/.LatinIME;816242702;-921088104");//选中的输入法
loadSetting(stmt, Settings.Secure.DEFAULT_INPUT_METHOD, "com.android.inputmethod.latin/.LatinIME");// 默认输入法为系统输入法
loadSetting(stmt, Settings.Secure.SELECTED_INPUT_METHOD_SUBTYPE, "816242702"); // 默认输入法的默认语言android.provider.Settings的Secure和System常量
