MTK平台修改音量默认值需要改动的位置

1，修改frameworks/base/media/java/android/media/AudioManager.java中的DEFAULT_STREAM_VOLUME数组

* @hide Default volume index values for audio streams

* M: modify the default stream volume @{

*/

public static final int[] DEFAULT_STREAM_VOLUME = new int[] {

4,  // STREAM_VOICE_CALL

15,  // STREAM_SYSTEM

12,  // STREAM_RING

12,// STREAM_MUSIC

12,  // STREAM_ALARM

12,  // STREAM_NOTIFICATION

7,  // STREAM_BLUETOOTH_SCO

15,  // STREAM_SYSTEM_ENFORCED

11,// STREAM_DTMF

11,  // STREAM_TTS

12,  // STREAM_FM

};

2，修改mediatek/frameworks/base/media/audio/java/com/mediatek/audioprofile/AudioProfileManager.java中

的getDefaultState方法中的

/** Default values of ringer volume for different audio profiles. */

final int DEFAULT_RINGER_VOLUME_GENERAL =12;

final int DEFAULT_RINGER_VOLUME_SILENT =0;

final int DEFAULT_RINGER_VOLUME_MEETING =0;

final int DEFAULT_RINGER_VOLUME_OUTDOOR =15;

/** Default values of notification volume for different audio profiles. */

final int DEFAULT_NOTIFICATION_VOLUME_GENERAL = 12;

final int DEFAULT_NOTIFICATION_VOLUME_SILENT = 0;

final int DEFAULT_NOTIFICATION_VOLUME_MEETING = 0;
