这段代码看起来是一个网络带宽管理器的类，其中包含了获取可用带宽比例和检查带宽是否可用的两个方法。在获取可用带宽比例的方法中，如果当前已连接用户数小于等于0，则返回初始容量和最大带宽的较小值；否则，返回初始容量除以已连接用户数和最大带宽的较小值。在检查带宽是否可用的方法中，首先计算当前实际带宽，即初始容量和最大带宽的较小值。接着，计算加入一个用户后的可用带宽，即实际带宽除以已连接用户数加1。如果加入一个用户后的可用带宽小于保证带宽，则返回 False，表示带宽不可用；否则，返回 True，表示带宽可用。

要将这些函数修改为最小容量的资源分配，需要进行以下更改：

1. 在 `is_avaliable` 函数中，将 `bandwidth_next` 的计算方式修改为 `real_cap / (self.connected_users + 1) >= self.bandwidth_min`，即下一个用户的带宽大于等于最小容量。

2. 在 `start_consume` 函数中，将 `amount` 的计算方式修改为 `min(s.get_consumable_share(), self.usage_remaining, self.bandwidth_min)`，即需要分配的资源量为可用资源、剩余需求和最小容量的最小值。

修改后的代码如下：

    s = self.get_slice()

    self.stat_collector.incr_connect_attempt(self)

Could not determine the dependencies of task ':brsdk_demo:compileDebugJavaWithJavac'. > Could not resolve all task dependencies for configuration ':brsdk_demo:debugCompileClasspath'. > Could not resolve project :brsdk_channel_base.

看起来你在编译一个名为 `brsdk_demo` 的 Android 项目时出现了依赖问题。具体来说，该项目依赖于名为 `brsdk_channel_base` 的子项目，但该子项目无法找到匹配的配置。

你可以尝试以下步骤来解决这个问题：

1. 确保 `brsdk_channel_base` 子项目已经正确地添加到 `settings.gradle` 和 `build.gradle` 文件中。

2. 检查 `brsdk_channel_base` 子项目的 `build.gradle` 文件，确保该子项目正确地定义了其 `configurations`。

3. 重新构建项目并尝试清除 Gradle 缓存。可以使用以下命令清除缓存：

./gradlew cleanBuildCache

希望这些步骤能够帮助你解决问题。
