请参见图1，图1为本发明实施例提供的一种信息处理方法的流程示意图，包括以下步骤：
S101、当检测到应用的启动控制指令时，终端设备检测所述应用所依赖的目标dex文件对应的目标oat文件是否缺失。
S102、若所述目标oat文件缺失，所述终端设备检测是否存在备份的所述目标oat文件。
S103、若存在备份的所述目标oat文件，所述终端设备确定备份所述目标oat文件的硬链接文件，以及从所述硬链接文件中读取所述目标oat文件。
S104、所述终端设备验证所述目标oat文件是否有效。
S105、若所述目标oat文件有效，则所述终端设备加载所述目标oat文件。
其中，所述应用为终端设备安装的第三方应用，或者系统应用。
举例来说，通常主要的编译过程发生在应用程序安装的过程，另外一些应用程序运行时依赖于动态的java库文件，这些动态的java库文件也要求在运行前被编译成本地机器指令(即oat文件)。目前很多流行的应用，如愤怒的小鸟、地铁跑酷、神庙逃亡等，在每次冷启动(冷启动指的是应用第一次启动或者应用被杀死(不在内存中)后重新启动的情况。)时都进行了动态的java库文件的编译和加载。通常应用启动编译的动态的java库文件对应的oat文件属于缓存，这些编译后的oat文件会在应用程序加载完后进行删除，因此造成每次冷启动都重新进行一次动态的java库文件的编译，进而增加了终端设备的功耗。本方案中，在将目标dex文件(比如动态的java库文件)编译成目标oat文件之前，先确定终端设备中是否存在备份的目标oat文件，若存在，则终端设备直接从目标oat文件的硬链接文件中调用该目标oat文件即可。
可选地，图1所示的方法还包括：
若不存在备份的所述目标oat文件，所述终端设备编译所述目标dex文件，得到所述目标oat文件；所述终端设备建立备份所述目标oat文件的硬链接文 件，以及将所述目标oat文件存储于所述目标oat文件的硬链接文件中。
举例来说，在不存在备份的目标oat文件的情况下，该种情况可能是应用第一次被启动，此时，终端设备需编译目标dex文件，得到目标oat文件，以及加载该目标oat文件(或者是先验证目标oat文件是否有效，在该目标oat文件有效的情况下，再去加载目标oat文件)。另外，为了避免后续启动该应用时反复编译这些目标dex文件，而增加终端设备的功耗的问题，终端设备可将目标oat文件进行备份，备份目标oat文件的具体方式有：先建立备份目标oat文件的硬链接文件，然后再将目标oat文件存储于目标oat文件的硬链接文件中。
可选地，以上步骤S104验证所述备份的所述目标oat文件是否有效的具体实施方式为：所述终端设备确定所述目标oat文件的偏移数组的数量与所述目标dex文件的数据类型的数量是否相同；若所述目标oat文件的偏移数组的数量与所述目标dex文件的数据类型的数量相同，则确认所述目标oat文件有效；若所述目标oat文件的偏移数组的数量与所述目标dex文件的数据类型的数量不相同，则确认所述目标oat文件无效。
举例来说，通常dex文件包括N种数据类型，N种数据类型对应N个数据，N种数据对应N种编译方法，那么终端设备根据N种编译方法编译该dex文件中的N个数据得到的oat文件可包括N个偏移数组，N个数据与N个偏移数组一一对应，其中，N为大于或等于1的整数，N种编译方法可以相同也可以不同，本发明不作限定。因此，终端设备判断备份的目标oat文件是否有效，可通过判断备份的目标oat文件的偏移数组的数量与目标dex文件的数据类型的数量是否相同，来判断备份的目标oat文件是否有效，比如，备份的目标oat文件的偏移数组的数量为3，目标dex文件的数据类型的数量为3，则确认备份的目标oat文件有效，否则，确认备份的目标oat文件无效。
可选地，图1所示的方法还包括：
若所述目标oat文件无效，所述终端设备确定所述目标oat文件是否完整；若目标oat文件不完整，则所述终端设备确定所述目标dex文件未编译的目标数据，以及编译所述目标数据，得到目标编译数据；所述终端设备将所述目标编译数据添加至所述目标oat文件中，以及加载所述目标oat文件。
举例来说，目标oat文件无效的原因可能是目标oat文件不完整(导致目标oat文件不完整的原因可能在启动应用过程中，用户将该应用关闭，而导致终端设备未编译完目标dex文件，进而使得目标oat文件不完整)，也有可能是别的原因(比如应用更新后)。在目标oat文件无效的情况下，终端设备先确定目标oat文件是否完整，若否，终端设备先将目标oat文件完善，然后再加载目标oat文件(或者是先验证目标oat文件是否有效，在该目标oat文件有效的情况下，再去加载目标oat文件)。完善目标oat文件的具体实施方式可以有：终端设备先确定所述目标dex文件未编译的目标数据，以及编译目标数据，得到目标编译数据；然后终端设备将目标编译数据添加至目标oat文件中，以及加载目标oat文件，比如，目标oat文件包含的偏移数组的数量为1，目标dex文件包含数据类型的数量为3，则表示目标dex文件中有2个数据类型未编译，终端设备可通过目标oat文件包含的1个偏移数组对应的编译方法，确定目标dex文件中2未编译的数据类型是哪两个，然后终端设备再去编译这两个数据类型对应的数据，得到目标编译数据，最后终端设备再将编译后的目标编译数据添加到目标oat文件中，以使得目标oat文件完整。
可选地，图1所示的方法还包括：
在所述应用更新或卸载后，所述终端设备将备份的所述目标oat文件从所述目标oat文件的硬链接文件中删除。
举例来说，在应用更新或卸载后，终端设备认为该应用备份的目标oat文件后续用处可能不大，该种情况下，为了节省终端设备的存储空间，终端设备可将该应用备份的目标oat文件从备份目标oat文件的硬链接文件中删除。
可选地，所述方法还包括：
在所述应用更新或卸载后，将所述目标oat文件进行压缩，以得到压缩文件，以及将所述压缩文件存储至指定位置；
若在预设时长内所述应用未重新安装时，将所述压缩文件删除。
具体地，有时用户可能只是为了释放终端设备的一部分存储空间，而暂时将应用A卸载，后续用户需要的时候可能还会安装应用A，该种情况下，为了避免终端设备反复编译应用A所需要的目标oat文件，终端设备可先将应用A的目标oat文件进行压缩，得到压缩文件B，然后将压缩文件B存储至指定 位置，在后续用户在安装应用A时，直接将该压缩文件B进行解压备用，若应用A在预设时长(比如1个月)内未重新安装，则终端直接删除该压缩文件。
本发明实施例还提供了另一更为详细的方法流程，如图2所示，包括：
S201、当检测到应用的启动控制指令时，终端设备检测所述应用所依赖的目标dex文件对应的目标oat文件是否缺失。
若是，则执行步骤S202。
若否，则执行步骤S204。
S202、所述终端设备检测是否存在备份的所述目标oat文件。
若是，则执行步骤S203。
若否，则执行步骤S206。
S203、所述终端设备确定备份所述目标oat文件的硬链接文件，以及从所述硬链接文件中读取所述目标oat文件。
S204、所述终端设备验证所述目标oat文件是否有效。
若是，则执行步骤S205。
若否，则执行步骤S211。
S205、所述终端设备加载所述目标oat文件。
S206、所述终端设备编译所述目标dex文件，得到所述目标oat文件。
S207、所述终端设备确定所述目标dex文件是否为主执行文件。
若是，则执行步骤S204。
若否，则执行步骤S208。
S208、所述终端设备检测所述目标dex文件是否存在编译记录。
若是，则执行步骤S209。
若否，则执行步骤S210。
S209、所述终端设备建立备份所述目标oat文件的硬链接文件，以及将所述目标oat文件存储于所述目标oat文件的硬链接文件中。
S210、所述终端设备控制所述目标dex文件对应的编译计数器加1。执行完步骤S210后，执行步骤S204。
S211、所述终端设备确定所述目标oat文件是否完整；
若否，则执行步骤S212。
若是，则执行步骤S206。
S212、所述终端设备确定所述目标dex文件未编译的目标数据，以及编译所述目标数据，得到目标编译数据；
S213、所述终端设备将所述目标编译数据添加至所述目标oat文件中。执行完步骤S213后，执行步骤S204。
需要说明的是，图2所示的各个步骤的具体实现方式可参见上述方法的具体实现方式，在此不再叙述。另外，执行完步骤S206执行步骤S207，也可以执行完步骤S206后执行步骤S204，也可以执行完步骤S206后执行步骤S205。此外，步骤S207用于确保目标dex文件不来自主执行文件(/data/app/目录，/data/app目录为应用程序的主执行文件目录，主执行文件不存在反复编译的可能)，步骤S208进一步检查目标dex文件是否已经存在了编译的记录，如果已经存在一次编译记录，表示此次行为是二次编译，即符合反复编译的特征，步骤S210通过对目标dex文件对应的编译计数器进行加1以更新编译记录内容，以便于后续终端设备判断该目标dex文件是否被编译过，比如目标dex文件对应的编译计数器为0表示不被编译过，目标dex文件对应的编译计数器不为0表示被编译过。
