In my application I'm downloading movies from the server. Some of them are very big (4gb or more). I tried to implement my own download manager as a service and it was not quit good. On some devices the app just crashes into itself without any notice, and overall the download seems to be too slowly.

So, I wanted to use Android's default DownloadManager, but my only problem is that I can't pause/resume it.

Is there a way to implement that?

从我通过查看源代码可以看出，这是不支持的（尽管它DownloadManager会在自身发生故障后和系统重新启动后自动重试等）。

如果您还没有看到这个或这个，看起来那里有一些有用的信息，说明如何使用这些功能自己实现自己的服务。

您可以通过将 Downloads.Impl.COLUMN_CONTROL 设置为 Downloads.Impl.CONTROL_PAUSED 来暂停。

并通过设置 Downloads.Impl.COLUMN_CONTROL、Downloads.Impl.CONTROL_RUN 来恢复

    public void pauseOrResumeDownload(boolean pause, long... ids) {
    ContentValues values = new ContentValues();
    if (pause) {
        values.put(Downloads.Impl.COLUMN_CONTROL, Downloads.Impl.CONTROL_PAUSED);
    } else {
        values.put(Downloads.Impl.COLUMN_STATUS, Downloads.Impl.STATUS_PENDING);
        values.put(Downloads.Impl.COLUMN_CONTROL, Downloads.Impl.CONTROL_RUN);
    }
    mResolver.update(mBaseUri, values, getWhereClauseForIds(ids), getWhereArgsForIds(ids));
}
