具体实施方式detailed description
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
本发明实施例中的终端可以包括安装有Android系统的智能手机、平板电脑、掌上电脑、笔记本电脑、移动互联网设备(MID，MobileInternetDevices)或穿戴式设备等，上述终端仅是举例，而非穷举，包含但不限于上述终端。The terminal in the embodiment of the present invention may include a smart phone, a tablet computer, a handheld computer, a notebook computer, a mobile Internet device (MID, MobileInternetDevices) or a wearable device installed with an Android system, and the above-mentioned terminals are only examples, not exhaustive , including but not limited to the above terminals.
请参照图1，为本发明提供的Android系统升级的方法的第一实施例的流程示意图，在本实施例中，所述方法包括以下步骤：Please refer to Fig. 1, the schematic flow chart of the first embodiment of the method for upgrading the Android system provided by the present invention, in this embodiment, the method includes the following steps:
S101，接收用户输入的升级指令，下载升级包。S101. Receive an upgrade instruction input by a user, and download an upgrade package.
S102，在后台对所述升级包中的文件进行转化处理。S102. Perform conversion processing on the files in the upgrade package in the background.
其中，所述升级包中的文件包括系统归档(JavaArchive，简称JAR)文件、系统Android安装包(AndroidPackage，简称APK)以及用户安装的Android安装包。Wherein, the files in the upgrade package include a system archive (JavaArchive, JAR for short), a system Android installation package (Android Package, APK for short), and an Android installation package installed by a user.
所述转化处理包括odex转化处理或oat转化处理。两种转化处理根据终端当前所使用的虚拟机环境而定。The conversion treatment includes odex conversion treatment or oat conversion treatment. The two conversion processes are determined according to the virtual machine environment currently used by the terminal.
一般地，需要进行转化处理的文件路径为/system/framework/*.jar、/system/app/*.apk、/system/pri-app/*.apk、/vendor/app/*.apk以及/data/app/*.apk。*为应用名称。Generally, the file paths that need to be converted are /system/framework/*.jar, /system/app/*.apk, /system/pri-app/*.apk, /vendor/app/*.apk and / data/app/*.apk. * is the application name.
针对APK，还需要考虑版本号的差别，需要判别到底需要转化哪个APK，如果系统的APK已经升级过，则无需转化处理，已包含在/data/app中，具体的判断可以通过系统接口来进行。For APK, you also need to consider the difference in version number, and you need to determine which APK needs to be converted. If the APK of the system has been upgraded, there is no need to convert it, and it is already included in /data/app. The specific judgment can be made through the system interface. .
其中，当终端使用dalvikvm的虚拟机环境时，需要对升级包中的JAR文件、系统APK以及用户安装的APK进行odex转化处理。具体地，在dex环境下，将上述三种文件里的dex转化为odex，而在odex环境下，系统JAR文件已经是odex了，不需要转化；同时大部分APK也是odex，但是系统里仍有部分dex的APK，仍需要转化为odex，而且用户自行安装的APK也需要转化。其中，dex和odex均为安卓(Android)平台上的可执行文件的类型。且odex是安卓上的APK中提取出来的可运行文件，即将APK中的classes.dex文件通过dex优化过程将其优化生成一个dex文件单独存放，原APK中的classes.dex文件会保留，这样做可以加快应用的启动速度，预先提取，减少对RAM的占用，因为没有odex的话，系统要从apk包中提取dex再运行。Among them, when the terminal uses the dalvikvm virtual machine environment, it is necessary to perform odex conversion processing on the JAR file in the upgrade package, the system APK, and the APK installed by the user. Specifically, in the dex environment, the dex in the above three files is converted into odex, while in the odex environment, the system JAR file is already odex, and no conversion is required; at the same time, most APKs are also odex, but there are still Some dex APKs still need to be converted to odex, and APKs installed by users also need to be converted. Wherein, both dex and odex are types of executable files on the Android (Android) platform. And odex is an executable file extracted from the APK on Android, that is, the classes.dex file in the APK will be optimized through the dex optimization process to generate a dex file and stored separately, and the classes.dex file in the original APK will be retained. It can speed up the startup speed of the application, extract it in advance, and reduce the occupation of RAM, because if there is no odex, the system needs to extract the dex from the apk package and then run it.
另一种情况，当终端使用安卓运行环境(Androidruntime，简称art)的虚拟机环境时，不管是dex环境下还是odex环境下，都需要将升级包中包含的文件如系统JAR文件，系统APK，用户安装的APK转化为oat，且转化为oat的过程比转化为odex的过程更长。In another case, when the terminal uses the virtual machine environment of the Android runtime (art for short), no matter in the dex environment or the odex environment, the files contained in the upgrade package, such as the system JAR file, system APK, The APK installed by the user is converted to oat, and the process of converting to oat is longer than the process of converting to odex.
因此，若将这些转化过程放在Android系统升级重启之后进行，将使得终端在很长一段时间无法使用，占用用户大量的时间。因此本发明实施例中将转化的过程放置在后台运行，在转化时，用户仍可以正常使用未升级的系统，不会因为系统升级而对用户体验造成影响。Therefore, if these conversion processes are carried out after the Android system is upgraded and restarted, the terminal will be unusable for a long period of time, which will take up a lot of time for the user. Therefore, in the embodiment of the present invention, the conversion process is placed to run in the background. During the conversion, the user can still use the non-upgraded system normally, and the user experience will not be affected by the system upgrade.
S103，将转化处理后的文件保存至除系统升级缓存区的其他存储位置。S103. Save the converted file to a storage location other than the system upgrade cache area.
可选地，系统升级缓存区的路径一般为/data/dalvik-cache，在将升级包中的文件进行转化处理之后，只需要将转化处理后的文件保存至该路径之外的其他存储位置即可。Optionally, the path of the system upgrade cache area is generally /data/dalvik-cache. After converting the files in the upgrade package, you only need to save the converted files to other storage locations other than this path. Can.
S104，在recovery模式下将所述转化处理后的文件拷贝至所述系统升级缓存区，完成升级。S104. Copy the converted file to the system upgrade buffer area in the recovery mode to complete the upgrade.
当转化处理以及存储处理完成之后，用户便可以操作终端进入recovery模式，终端接收用户输入的操作指令进入recovery模式之后，便可以将转化处理后的文件从原来的存储位置拷贝至所述系统升级缓存区，这样终端重启之后，将直接读取转化完成之后的文件，而无需再显示“Android正在更新”并进行长时间的系统初始化，而是可以直接进入更新后的Android系统。After the conversion processing and storage processing are completed, the user can operate the terminal to enter the recovery mode. After the terminal receives the operation command input by the user and enters the recovery mode, the converted file can be copied from the original storage location to the system upgrade cache In this way, after the terminal restarts, it will directly read the converted file without displaying "Android is updating" and performing a long system initialization, but can directly enter the updated Android system.
通过接收用户输入的升级指令，下载升级包，然后在后台对所述升级包中的文件进行转化处理，并将转化处理后的文件保存至除系统升级缓存区之外的其他存储位置，然后在recovery模式下将所述转化处理后的文件拷贝至所述系统升级缓存区，完成升级，由于转化处理在后台进行，因此在升级过程中用户可照常使用旧系统；且转化完成后，将转化处理后的文件存储在非系统升级缓存区，并在recovery模式下将其拷贝至系统升级缓存区，从而使得Android的初始化过程大大缩短，升级直接完成，在升级过程中，用户可以使用旧系统，在升级完成后，终端可直接调用转化处理后的文件使用，这样用户也就可以直接在终端重启后直接使用新的系统，使得整个升级过程中，终端的不可使用时间大大缩短，提升了终端的易用性，也提升了用户体验。Download the upgrade package by receiving the upgrade instruction input by the user, and then convert the files in the upgrade package in the background, and save the converted file to a storage location other than the system upgrade cache area, and then in the In the recovery mode, the converted file is copied to the system upgrade cache to complete the upgrade. Since the conversion process is performed in the background, the user can use the old system as usual during the upgrade process; and after the conversion is completed, the conversion process The final file is stored in the non-system upgrade cache area, and copied to the system upgrade cache area in recovery mode, so that the initialization process of Android is greatly shortened, and the upgrade is completed directly.

Usability also improves user experience.

另一种情况，当终端使用安卓运行环境(Androidruntime，简称art)的虚拟机环境时，不管是dex环境下还是odex环境下，都需要将升级包中包含的文件如系统JAR文件，系统APK，用户安装的APK转化为oat，且转化为oat的过程比转化为odex的过程更长。In another case, when the terminal uses the virtual machine environment of the Android runtime (art for short), no matter in the dex environment or the odex environment, the files contained in the upgrade package, such as the system JAR file, system APK, The APK installed by the user is converted to oat, and the process of converting to oat is longer than the process of converting to odex.
因此，若将这些转化过程放在Android系统升级重启之后进行，将使得终端在很长一段时间无法使用，占用用户大量的时间。因此本发明实施例中将转化的过程放置在后台运行，在转化时，用户仍可以正常使用未升级的系统，不会因为系统升级而对用户体验造成影响。Therefore, if these conversion processes are carried out after the Android system is upgraded and restarted, the terminal will be unusable for a long period of time, which will take up a lot of time for the user. Therefore, in the embodiment of the present invention, the conversion process is placed to run in the background. During the conversion, the user can still use the non-upgraded system normally, and the user experience will not be affected by the system upgrade.
S304，将转化处理后的文件保存至外置安全数码卡中。S304, saving the converted file to an external secure digital card.
可选地，系统升级缓存区的路径一般为/data/dalvik-cache，在将升级包中的文件进行转化处理之后，只需要将转化处理后的文件保存至该路径之外的其他存储位置即可。例如，可以是外置安全数码卡中，当然也可以是终端内置存储中除系统升级缓存区的其他存储路径。Optionally, the path of the system upgrade cache area is generally /data/dalvik-cache. After converting the files in the upgrade package, you only need to save the converted files to other storage locations other than this path. Can. For example, it can be in an external secure digital card, and of course it can also be in other storage paths in the built-in storage of the terminal except the system upgrade buffer area.
S305，在recovery模式下将所述转化处理后的文件拷贝至所述系统升级缓存区，完成升级。S305. In the recovery mode, copy the converted file to the system upgrade cache area to complete the upgrade.
当转化处理以及存储处理完成之后，用户便可以操作终端进入recovery模式，终端接收用户输入的操作指令进入recovery模式之后，便可以将转化处理后的文件从原来的存储位置拷贝至所述系统升级缓存区，这样终端重启之后，将直接读取转化完成之后的文件，而无需再显示“Android正在更新”并进行长时间的系统初始化，而是可以直接进入更新后的Android系统。After the conversion processing and storage processing are completed, the user can operate the terminal to enter the recovery mode. After the terminal receives the operation command input by the user and enters the recovery mode, the converted file can be copied from the original storage location to the system upgrade cache In this way, after the terminal restarts, it will directly read the converted file without displaying "Android is updating" and performing a long system initialization, but can directly enter the updated Android system.
