音频管理器服务

mAudioManager所在服务如下：
　　文件： frameworks/base/media/java/android/media/AudioManager.java

java代码：

1. public static final int RINGER_MODE_SILENT = 0;
3. public static final int RINGER_MODE_VIBRATE = 1;
5. public static final int RINGER_MODE_NORMAL = 2;
7. public void setRingerMode(int ringerMode) {
9. IAudioService service = getService();
11. try {
13. service.setRingerMode(ringerMode);
15. } catch (RemoteException e) {
17. Log.e(TAG, "Dead object in setRingerMode", e);
19. }
21. }

        将铃响模式值传给音频接口服务IaudioService

java代码：

1. public static final int VIBRATE_TYPE_RINGER = 0;
3. public static final int VIBRATE_TYPE_NOTIFICATION = 1;
5. public static final int VIBRATE_SETTING_OFF = 0;
7. public static final int VIBRATE_SETTING_ON = 1;
9. public static final int VIBRATE_SETTING_ONLY_SILENT = 2;
11. public void setVibrateSetting(int vibrateTyp , int vibrateSetting) {
13. IAudioService service = getService();
15. try {
17. service.setVibrateSetting(vibrateType, vibrateSetting);
19. } catch (RemoteException e) {
21. Log.e(TAG, "Dead object in setVibrateSetting", e);
23. }
25. }

        将振动类型和振动设置传给音频接口服务IaudioService,IaudioService的定义如下:
        frameworks/base/media/java/android/media/IAudioService.aidl
        frameworks/base/media/java/android/media/AudioService.java
        文件: frameworks/base/media/java/android/media/AudioService.java
        文件: frameworks/base/core/java/android/provider/Settings.java

java代码：

1. public void setRingerMode(int ringerMode) {
3. synchronized (mSettingsLock) {
5. if (ringerMode != mRingerMode) {
7. setRingerModeInt(ringerMode, true);
9. // Send sticky broadcast
11. broadcastRingerMode();
13. }
15. }
17. }
