语音搜索的权限

Question

在我的ICS(Android 4.0.4)平板电脑上运行Google语音搜索会产生奇怪的行为,并出现以下警告:

W/PackageManager( 1571): Unknown permission com.google.android.voicesearch.SHORTCUTS_ACCESS in package com.google.android.googlequicksearchbox
W/PackageManager( 1571): Unknown permission com.google.android.voicesearch.AUDIO_FILE_ACCESS in package com.google.android.gm
W/RecognitionManagerService( 1571): no available voice recognition services found
I/ActivityManager( 1571): Start proc com.android.voicedialer for broadcast com.android.voicedialer/.VoiceDialerReceiver: pid=2130 uid=10033 gids={3002}
I/ActivityManager( 1571): No longer want com.android.voicedialer (pid 2130): hidden #16
I/ActivityManager( 1571): Force stopping package com.google.android.voicesearch uid=10074
W/PackageManager( 1571): Unknown permission com.google.android.apps.googlevoice.permission.AUTO_SEND in package com.google.android.voicesearch
D/BackupManagerService( 1571): Received broadcast Intent { act=android.intent.action.PACKAGE_ADDED dat=package:com.google.android.voicesearch flg=0x10000010 (has extras) }

很想知道为什么,我查了一下Manifest.permission列表,但我找不到任何提及:

• SHORTCUTS_ACCESS
• AUDIO_FILE_ACCESS
• AUTO_SEND

这些权限是什么以及我可以在哪里了解更多相关信息？

Answer 1

这些权限在语音搜索 APK 和 GMail APK 内部定义。它们是私有权限，受 APK 签名保护。

它们用于限制对内部应用程序数据和私有 Intent 目标的访问，并且不希望用户可见。
