具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
参照下面的描述和附图，将清楚本发明的实施例的这些和其他方面。在这些描述和附图中，具体公开了本发明的实施例中的一些特定实施方式，来表示实施本发明的实施例的原理的一些方式，但是应当理解，本发明的实施例的范围不受此限制。相反，本发明的实施例包括落入所附加权利要求书的精神和内涵范围内的所有变化、修改和等同物。
请参阅图1，为本发明第一实施例中的双系统内存共享方法，包括步骤S11～S12。
步骤S11，进行文件写入时，分别计算第一系统和第二系统的内存的可用容量。
本实施例中，所述第一系统及所述第二系统均安装在同一个双系统智能交互设备上，该双系统智能交互设备例如为交互智能平板，其具有两个Android(安卓)模块分别加载两个Android系统。其中可插拔的Android模块作为Slave机，另一个Android模块作为Host机。本实施例中的第一系统为作为Host机的Android系统，第二系统为Slave机的Android系统。
两个Android系统通过局域网或者通过ADB(Android Debug Bridge，Android调试桥接器)调试通道连接，并进行信息交互。在所述双系统智能交互设备中，第一系统及第二系统均具有一套独立的硬件，如各自具有一个内存。当然，第 一系统及第二系统也可共用特定的硬件，如键盘、鼠标或者触摸屏等。
第一系统和第二系统可通过系统接口计算存储空间可用、已用、总的容量，第二系统将计算好的数值通过局域网或者通过ADB调试通道同步通知给第一系统。即可得到第一系统和第二系统的内存的可用容量以及第一系统和第二系统的内存的总可用容量。
步骤S12，当所述第一系统和所述第二系统的内存的可用容量均小于写入的当前文件的占用空间，且所述第一系统和所述第二系统的内存的总可用容量大于所述当前文件的占用空间时，将所述当前文件分割为两个分块，分别存储在所述第一系统和所述第二系统中。其中，储存在所述第一系统的所述分块的占用空间小于或等于所述第一系统的内存的可用容量，存储在所述第二系统的所述分块的占用空间小于或等于所述第二系统的内存的可用容量。
现有技术中，当两个系统的内存的可用容量均小于写入的当前文件的占用空间，且两个系统的总可用容量大于当前文件的占用空间时，无法充分利用两个系统的内存进行文件的存储。
为了解决这一问题，本实施例将写入的文件进行分割分别存储在两个系统中。在进行文件分割和存储时，按照预设的分割方案进行文件分割，将当前系统的内存使用完后再使用另外一个系统的内存。即，根据所述第一系统的内存的可用容量分割所述当前文件，得到占用空间等于所述第一系统的内存的可用容量的分块，并将其存储在所述第一系统中；将分割后的所述当前文件的剩余部分存储在所述第二系统中。
例如，第一系统需要写入一个80MB的视频文件，第一系统的内存的可用容量为60MB，第二系统的内存的可用容量为40MB时，将该80MB的文件分割为60MB和20MB的两个分块，分别存储在第一系统和第二系统中。
可以理解的，对当前文件进行分割时，也可以按照两个系统的内存的可用容量的比例进行分割。例如第一系统需要写入一个80MB的视频文件，第一系统的内存的可用容量为60MB，第二系统的内存的可用容量为40MB，第一系统和所述第二系统的内存的可用容量之比等于3/2，将该80MB的文件分割为占用空间分别等于48MB和32MB的两个分块，分别存储在第一系统和第二系统中。 当然，也可以预设其他的分割方案。
本实施例通过将写入的文件分割为两部分，分别存在两个系统中。解决了两个系统的内存的可用容量均小于写入的当前文件的占用空间，且两个系统的内存总可用容量大于当前文件的占用空间时，无法存储写入的文件的问题，提高了双系统内存的利用效率。
可以理解的，在本发明其他实施例中提到的系统除了为Android系统，还可以是Windows Phone系统(WP系统)、Windows系统、或IOS系统(苹果移动设备操作系统)。所述双系统可以是两个相同的系统，也可以是两个不同的系统。
请参阅图2，为本发明第二实施例中的双系统内存共享方法，包括步骤S21～S25。
步骤S21，进行文件写入时，分别计算第一系统和第二系统的内存的可用容量。
步骤S22，当所述第一系统和所述第二系统的内存的可用容量均小于写入的当前文件的占用空间，且所述第一系统和所述第二系统的内存的总可用容量大于所述当前文件的占用空间时，将所述当前文件分割为两个分块，分别存储在所述第一系统和所述第二系统中。
上述步骤中，按照所述第一系统和所述第二系统的内存的可用容量之比将所述当前文件分割成为占用空间之比等于所述可用容量之比的两个分块，并分别存储在所述第一系统和所述第二系统中。
步骤S23，当监测到任意一系统的存储文件发生删除或移除时，计算发生存储文件删除或移除后的当前系统的内存的可用容量。
步骤S24，判断另一系统中的所述分块的占用空间是否小于或等于所述当前系统的内存的可用容量，若是，将所述另一系统中的所述分块移动至所述当前系统中。所述分块通过局域网或者通过ADB调试通道进行系统间的移动，其中ADB调试通道主要适用于两个系统均为Android系统的设备中。
如若两个系统中存在多个文件的分块，则根据分割的时间的先后顺序依次进行分割后的文件的合并。即，先分割的文件的两个分块优先进行合并，一个文件合并完成后在进行下一个文件的合并，直至当前系统的内存的可用容量不 足以容纳另一系统中任何一个分块。
可以理解的，也可以根据被分割的文件的优先级进行分块的合并。即优先级越高的文件，越先进行合并。
步骤S25，将所述当前系统中属于同一文件的两个所述分块合并为原文件。
读取文件时，需要将分割后的文件的两个分块进行合并，本实施例中，不仅充分利用两个系统的内存对写入的文件进行分割，而且将分割后的文件进行合并。本实施例通过设置存储空间监控服务，实时监测第一系统和第二系统的内存变化。当任意一系统，例如第一系统的存储文件发生删除或移动到其他存储空间时，第一系统的内存因此增加。此时，计算第一系统的内存的可用容量，并判断第二系统中的分块的占用空间是否小于或等于第一系统的内存的可用容量。如是，则将第二系统的所述分块移动到第一系统中，并与其对应的另一个分块合并成原文件。
可以理解的，当第二系统的存储文件发生删除或移动时，对分割后的文件的合并过程与上述过程基本相同，在此不再赘述。
请参阅图3，为本发明第三实施例中的双系统内存共享方法，包括步骤S31～S40。
步骤S31，进行文件写入时，分别计算第一系统和第二系统的内存的可用容量。
步骤S32，判断所述第一系统的内存的可用容量是否大于或等于写入的当前文件的占用空间，若是，执行步骤S33，否则执行步骤S34。
步骤S33，将所述当前文件存储在所述第一系统中。
步骤S34，判断所述第二系统的内存的可用容量是否大于或等于写入的当前文件的占用空间，若是执行步骤S35，否则执行步骤S36。
步骤S35，将所述当前文件存储在所述第二系统中。
步骤S36，判断第一系统和第二系统的内存的总可用容量是否大于所述当前文件的占用空间，若是，执行步骤S37。
步骤S37，将所述当前文件分割为两个分块，分别存储在所述第一系统和所述第二系统中。并且，储存在所述第一系统的所述分块的占用空间小于或等于 所述第一系统的内存的可用容量，存储在所述第二系统的所述分块的占用空间小于或等于所述第二系统的内存的可用容量。
上述步骤中，当所述当前文件分割为两个分块时，将所述当前文件的分割信息保存在第一系统中，所述分割信息包括每个所述分块的存储路径信息、每个所述分块的占用空间、每个所述分块的MD5值和每个所述分块的所属文件信息。
步骤S38，当监测到任意一系统的存储文件发生删除或移除时，计算发生存储文件删除或移除的当前系统的内存的可用容量。
步骤S39，判断另一系统中的所述分块的占用空间是否小于或等于所述当前系统的内存的可用容量，若是，将所述另一系统中的所述分块移动至所述当前系统中。
上述步骤，根据所述第一系统存储的每个所述分块的存储路径信息和每个所述分块的占用空间查找所述另一系统中的分块及确定其占用空间是否小于或等于所述当前系统的内存的可用容量。
步骤S40，将所述当前系统中属于同一文件的两个所述分块合并为原文件。
上述步骤中，根据所述当前系统存储的每个所述分块的所属文件信息将属于同一文件的两个分块合并为原文件。两个分块合并后根据MD5值确认文件的完整性。
当写入文件时，如果第一系统或第二系统的内存的可用容量足够时，将写入的文件存储在内存足够的系统中。如果两个系统的内存均不够，且两个系统的内存的总的可用容量足够时则将写入的文件分割为两个分块分别存储在两个系统中。
文件进行分割时，将文件的分割信息保存在第一系统中。所述分割信息包括：
每个所述分块的存储路径信息，即每个所述分块存储在对应系统的存储空间的路径，便于文件合并过程中查找和移动所述分块；
每个所述分块的占用空间，即每个所述分块的大小；
每个所述分块的所属文件信息，即每个所述分块属于哪个文件。文件合并 过程中根据每个所述分块的所属文件信息将原本属于同一文件的两个分块合并成原文件。
进一步的，分割的文件合并后，删除合并后的文件的分割信息。
