Simple Use Guideline

I. Task Start and Cancel

1. Start a task

task = new DownloadTask.Builder(url, parentFile)
         .setFilename(filename)
         // the minimal interval millisecond for callback progress
         .setMinIntervalMillisCallbackProcess(30)
         // do re-download even if the task has already been completed in the past.
         .setPassIfAlreadyCompleted(false)
         .build();

task.enqueue(listener);

// cancel
task.cancel();

// execute task synchronized
task.execute(listener);

2. Start tasks

// This method is optimize specially for bunch of tasks
DownloadTask.enqueue(tasks, listener);

// cancel, this method is also optmize specially for bunch of tasks
DownloadTask.cancel(tasks);

II. Queue Build, Start and Stop

DownloadContext.Builder builder = new DownloadContext.QueueSet()
        .setParentPathFile(parentFile)
        .setMinIntervalMillisCallbackProcess(150)
        .commit();
builder.bind(url1);
builder.bind(url2).addTag(key, value);
builder.bind(url3).setTag(tag);
builder.setListener(contextListener);

DownloadTask task = new DownloadTask.Builder(url4, parentFile)
        .setPriority(10).build();
builder.bindSetTask(task);

DownloadContext context = builder.build();

context.startOnParallel(listener);

// stop
context.stop();

III. Get State and Info

Normally you can get state and info on DownloadListener.

1. Get download state beyond listener

Status status = StatusUtil.getStatus(task)

status = StatusUtil.getStatus(url, parentPath, null);
status = StatusUtil.getStatus(url, parentPath, filename);

boolean isCompleted = StatusUtil.isCompleted(task);
isCompleted = StatusUtil.isCompleted(url, parentPath, null);
isCompleted = StatusUtil.isCompleted(url, parentPath, filename);

Status completedOrUnknown = StatusUtil.isCompletedOrUnknown(task);

// If you set tag, so just get tag
task.getTag();
task.getTag(xxx);

2. Get BreakpointInfo beyond listener

// Note: the info will be deleted since task is completed download for data health lifecycle
BreakpointInfo info = OkDownload.with().breakpointStore().get(it);

info = StatusUtil.getCurrentInfo(url, parentPath, null);
info = StatusUtil.getCurrentInfo(url, parentPath, filename);

// Since okdownload v1.0.1-SNAPSHOT
// the info reference will be cached on the task refrence even if the task is completed download.
info = task.getInfo();

IV. Listener
