android.process.acore和system进程

从源码看来，android.process.acore进程应该是一些基本功能的载入程序。

android-4.3_r2.2中，它包括以下项目：

1.UserDictionaryProvider

android.process.acore和system进程android.process.acore和system进程
<application android:process="android.process.acore"

        android:label="@string/app_label"

        android:allowClearUserData="false"

        android:backupAgent="DictionaryBackupAgent"

        android:killAfterRestore="false"

        >

2.ApplicationsProvider

<application android:process="android.process.acore" android:label="@string/app_label">

3.ContactsProvider

<application android:process="android.process.acore"

        android:label="@string/app_label"

        android:icon="@drawable/app_icon"

        android:allowBackup="false">

同样在android-4.3_r2.2中，system进程包括以下项目：

1.InputDevices

2.SettingsProvider

                 android:killAfterRestore="false"

                 android:icon="@drawable/ic_launcher_settings">

可以看到，Google正在减少共用进程。
