步骤 S104,多媒体仲裁模块根据多媒体资源的占用情况和 /或第一应用程序的优先 级对申请的多媒体资源进行仲裁。 通过本发明实施例, 采用如下方法: 移动终端接收来自自身设备中应用程序的多 媒体资源申请, 并根据多媒体资源的占用情况和 /或该应用程序的优先级进行多媒体资 源的仲裁, 即通过多媒体资源的占用情况与该应用程序的优先级判断多媒体资源的占 用情况, 解决了相关技术中多媒体资源的管理方法存在缺陷, 动、 静态应用在申请资 源的过程中, 只要有动态应用开启, 静态应用就立刻关闭, 导致用户体验降低的问题, 进而给出了合理的管理多媒体资源的方法, 使动、 静态应用合理开启和关闭, 合理利 用多媒体资源, 提升系统性能, 提高用户体验。 在步骤 S102执行之前,第一应用程序向多媒体仲裁模块进行应用信息的注册来申 请多媒体资源。 在实施过程中, 第一应用程序进行注册的注册信息可以包括多媒体资 源的类型, 也可以包括该应用程序自身的优先级, 通过多种应用信息, 可以灵活的进 行多媒体资源的仲裁。 在执行过程中, 应用程序向多媒体仲裁模块进行应用信息的注册来申请资源, 应 用信息注册包括了该应用程序使用的多媒体资源的类型: 音频解码、 音频编码、 视频 编码、 视频解码等; 该应用程序的优先级, 按照不同的移动终端应用的区分可以自由 划分一些优先级等级, 优选地, 本实施例可以在设计之初, 就预留一些优先级值供动 态应用后续开发时使用, 当运营商进行动态应用定制的时候, 开发者只需将预留的优 先级使用于动态应用中即可参与多媒体资源的有效仲裁。 本实施例中, 多媒体仲裁模块根据已注册的应用信息对多媒体资源是否被占用进 行裁决, 若注册成功应用程序既可以向多媒体仲裁模块进行资源的打开、播放、暂停、 恢复、 关闭以及注册回调函数或消息操作。 在步骤 S104的执行过程中,可以包括以下进一步处理: 多媒体仲裁模块判断多媒 体资源是否被第二应用程序所占用, 如果否, 则将向第一应用程序返回资源申请成功 消息, 并记录第一应用程序的应用信息。 在第一应用程序关闭后 (即第一应用程序将 多媒体资源释放后),多媒体仲裁模块将第一应用程序之前注册的应用信息进行删除处 理。 其中, 上述第一应用程序可以为静态应用程序, 第二应用程序可以为动态应用程 序, 或者, 第一应用程序可以为动态应用程序, 第二应用程序可以为静态应用程序, 当然, 也可以第一与第二应用程序同时为动态应用程序或静态应用程序。 多媒体仲裁模块判断多媒体资源是否被第二应用程序所占用包括两种情况, 上述 给出了一种没被占用的情况, 下面, 介绍资源被占用的情况, 即多媒体资源被第二应 用程序占用, 则比较第一应用程序与第二应用程序的优先级大小; 根据优先级比较结 果进行多媒体资源的仲裁。 通过第一与第二应用的比较进行仲裁的方法, 提升了系统 的性能, 使系统多媒体资源的仲裁更加人性化。 其中, 根据优先级比较结果进行多媒体资源的仲裁可以包括以下处理, 即当第一 应用程序和第二应用程序的优先级不同时, 则将多媒体资源分配给优先级较大的应用 程序; 当第一应用程序和第二应用程序的优先级相同时, 则将多媒体资源分配给处于 前台的应用程序。 上述过程包含了两个方面, 也就是说, 在优先级能比较出大小的情 况下, 通过优先级来判断是否把多媒体资源分配给当前申请的应用。 例如, 设置视频 的优先级高于音频的优先级, 则在音频申请多媒体资源的情况下, 系统查看优先级, 证明视频的优先级高于音频的优先级, 则不把该多媒体资源分配到音频程序中。 实施过程中, 当优先级无法解决资源分配的问题时, 可以认为当前优先级相同, 此时, 可以将通过判断哪一应用处于前台, 则将多媒体资源分配给该应用, 同时, 另 一应用不进行关闭, 而是处于挂起 (即停留在当前进程所处时刻) 状态。 处于前台的 应用程序关闭后, 则会释放其占用的多媒体资源, 此时, 多媒体资源处于未被占用的 状态, 处于后台挂起状态的应用程序会重新占用该多媒体资源, 并同时切换至前台, 开始运行该应用程序。 在应用程序运行过程中, 可以根据用户的实际需要进行前、 后 台切换, 进一步提升了用户体验。 优选实施例一 相关技术中的多媒体仲裁机制是当一个应用程序进行多媒体资源的申请的时候, 多媒体仲裁模块只是将记录的静态信息进行判断返回, 特别对动态应用采用一刀切, 不管动态应用是否涉及多媒体资源, 移动终端都会将本地静态应用直接关闭, 该方法 显得很不人性化。 基于上述考虑, 本发明优选实施例给出了对手机终端中静态应用以及动态应用进 行多媒体资源仲裁、分配以及可重入情况下资源的自动重新分配的方法, 该方法包括: 应用程序向多媒体仲裁模块进行应用信息的注册来申请资源, 多媒体仲裁模块根据已 注册的应用信息对多媒体资源是否互斥进行裁决, 若注册成功应用程序既可以向多媒 体仲裁模块进行资源的打开、 播放、 暂停、 恢复、 关闭以及注册回调函数或消息操作, 多媒体仲裁模块提供了应用前后台切换通知接口, 解决了相同优先级的应用间互相重 入带来的问题, 相应的多媒体仲裁模块提供了应用程序的多媒体资源应用信息的反注 册接口。 在应用程序向多媒体仲裁模块进行应用信息的注册来申请资源的过程中, 应用信 息注册包括了该应用程序使用的多媒体资源的类型: 音频解码、音频编码、视频编码、 视频解码等; 该应用程序的优先级, 按照不同的手机移动终端应用的区分可以自由划 分一些优先级等级, 优选地, 本实施例可以在设计之初, 就预留一些优先级值供动态 应用后续开发时使用, 当运营商进行动态应用定制的时候, 开发者只需将预留的优先 级使用于动态应用中即可参与多媒体资源的有效仲裁。 多媒体仲裁模块根据已注册的应用信息对多媒体资源是否互斥进行裁决。 若不存 在多媒体资源的互斥(即多媒体资源没被占用), 则直接返回成功, 并将对应的应用信 息记录; 若存在资源互斥的情况, 则进行应用优先级等条件的判断是否进行前一个的 应用的占用资源释放以供新申请的应用使用, 还是直接返回资源申请失败。 多媒体仲裁模块还提供了应用前后台通知接口, 解决了相同优先级的静态应用与 动态应用间互相重入带来的问题, 当同一优先级的应用譬如音乐播放器先后台播放再 进行某动态应用的背景音乐播放, 当某动态应用最小化以后, 重新进入音乐播放器由 应用调用聚焦接口通知多媒体仲裁模块有应用进行了前后台切换, 仲裁模块经判断新 的聚焦模块后将某动态应用的解码资源暂时释放, 同时将音频播放器恢复。 优选地, 多媒体仲裁模块提供了应用程序的多媒体资源应用信息的反注册接口, 就是将对应应用在多媒体仲裁模块中的应用信息记录全部删除。 下面结合图 2对本发明具体实施例作进一步的详细描述。 图 2是根据本发明一个优选实施例的静态应用与动态应用之间的多媒体资源仲裁 示意图, 包括步骤 S202至步骤 S228: 步骤 S202, 静态应用 1提供应用信息, 向多媒体仲裁模块进行多媒体资源申请。 步骤 S204,多媒体仲裁模块判断多媒体资源是否闲置。若闲置,则执行步骤 S206, 直接返回成功; 若不闲置, 则执行步骤 S210。 步骤 S206, 多媒体仲裁模块通知静态应用 1其申请多媒体资源成功。 步骤 S208, 静态应用可以对资源进行打开、 播放以及注册回调操作。 步骤 S210, 动态应用 2此时向静态应用 1提供应用信息, 进行多媒体资源申请。 步骤 S212, 多媒体仲裁模块判断多媒体资源已被静态应用 1占用, 根据应用优先 级仲裁多媒体资源, 将静态应用 1 占用的资源进行释放, 并将此时的资源状态记录下 来, 方便后续恢复。 步骤 S214, 多媒体仲裁模块通知静态应用 1其申请的多媒体资源已被释放。 步骤 S216,静态应用 1收到该通知后进行应用自身的暂停状态置位等一系列操作。 步骤 S218, 多媒体仲裁模块通知动态应用 2其申请多媒体资源成功。 步骤 S220, 动态应用 2可以对资源进行打开、 播放以及注册回调操作。 步骤 S222, 当动态应用 2不需要运行时, 则退出前需要进行应用资源的关闭、 释 放操作。 步骤 S224, 多媒体仲裁模块判断静态应用 1需要恢复, 将其资源按照上次的参数 记录状态打开。 步骤 S226, 多媒体仲裁模块通知静态应用 1多媒体资源已被恢复。 步骤 S228,静态应用 1收到该通知后的进行应用自身的恢复状态置位等一系列操 作。 优选实施例二 图 3是根据本发明优选实施例的相同优先级静态应用与动态应用之间的可重入多 媒体资源仲裁示意图, 包括步骤 S302至步骤 S332: 步骤 S302, 静态应用 1提供应用信息, 向多媒体仲裁模块进行多媒体资源申请。 步骤 S304,多媒体仲裁模块判断多媒体资源是否闲置。若闲置,则执行步骤 S306, 直接返回成功; 若不闲置, 则执行步骤 S310。 步骤 S306, 多媒体仲裁模块通知静态应用 1其申请多媒体资源成功。 步骤 S308, 静态应用可以对资源进行打开、 播放以及注册回调操作。 步骤 S310, 动态应用 2此时向静态应用 1提供应用信息, 进行多媒体资源申请。 步骤 S312, 多媒体仲裁模块判断多媒体资源已被静态应用 1占用, 根据应用优先 级仲裁多媒体资源, 将静态应用 1 占用的资源进行释放, 并将此时的资源状态记录下 来, 方便后续恢复。 步骤 S314, 多媒体仲裁模块通知静态应用 1其申请的多媒体资源已被释放。 步骤 S316,静态应用 1收到该通知后进行应用自身的暂停状态置位等一系列操作。 步骤 S318, 多媒体仲裁模块通知动态应用 2其申请多媒体资源成功。 步骤 S320, 动态应用 2可以对资源进行打开、 播放以及注册回调操作。 步骤 S322, 此时在用户前换了应用的前后台, 将静态应用 1切换到了前台, 静态 应用 1向多媒体仲裁模块提供该应用的前台状态通知。 步骤 S324, 多媒体仲裁模块判断静态应用 1需要恢复, 根据应用优先级仲裁多媒 体资源, 将动态应用 2占用的资源进行释放, 并将此时的资源状态记录下来, 方便后 续恢复。 步骤 S326, 多媒体仲裁模块通知动态应用 2其申请的多媒体资源已被释放。 步骤 S328,动态应用 2收到该通知后进行应用自身的暂停状态置位等一系列操作。 步骤 S330,多媒体仲裁模块按照对应静态应用 1的记录将静态应用 1的资源恢复, 并通知静态应用 1其资源已经被恢复。 步骤 S332,静态应用 1收到该通知后进行应用自身的恢复状态置位等一系列操作。 本发明实施例还提供了一种移动终端多媒体资源的管理装置, 应用于移动终端, 如图 4所示, 该装置包括: 接收模块 10, 设置为接收来自移动终端中的第一应用程序 的多媒体资源申请;
