Fix

  • Fix(crash): Fix provided wrong params in formatting character string when to starting download runnable occur the unexpected downloading status.
  • Fix(force-re-download): Fix the wrong logic: In the case of BaseDownloadTask#setForceReDownload(true) and the task has already downloaded will trigger 'warn' callback. Closes #169 .
  • Fix(class-type): Keep the class type of SocketTimeOutException, and no longer care about whether the message of Throwable is empty, this is very redundant.

Others

  • Add new call-back method in FileDownloadListener: started which will be invoked when finish pending, and start the download runnable.
  • Add new call-back method in FileDownloadMonitor.IMonitor: onTaskStarted which will be invoked when finish pending, and start the download runnable.

Enhancement

  • Improve Practicability: Provide the current task to the method over in FinishListener, for recognizing target task in case of one-FinishListener for more than one task. Closes #69 .
  • Improve Robust: Throw the exception directly when invoke BaseDownloadTask#start for a running-task object, add provide 'reuse' method to reuse a used and already finished task object. Closes #91 .

Fix

  • Fix: In handful cases the task-call-back flow not follow the expect.
  • Fix: progress call-back included the ending frame ( sofarBytes == totalBytes ).
  • Fix: Carry back the total bytes in the status of warn, for covering the case of UI-process had killed but has restarted App with restarting the task and download-process is alive still, the total bytes is 0 in UI-process. Closes #90 .

  • Improve Practicability: Support resume from breakpoint without ETag. Just need the server support the request-header param 'Range'. Close #35 , #66 .

Fix

  • Fix: The IllegalFormatConversionException on EventPool when publishing the event which does not in effect and FileDownloadLog.NEED_LOG is true. Closes #30 .
  • Fix: The non-fatal-crash in IFileDownloadIPCService.java , when lost connection from filedownloader process. because the IBinder's hosting process(filedownloader process) has been killed/cancelled. Closes #38 .

Version 0.1.9

2016-01-23

FileDownloader is enable Avoid Missing Screen Frames as default, if you want to disable it, please invoke FileDownloader.getImpl().disableAvoidDropFrame().

New Interfaces

We default open Avoid Missing Screen Frames, if you want to disable it(will post to ui thread for each FileDownloadListener event achieved as pre version), please invoke: FileDownloader.getImpl().disableAvoidDropFrame().

  • FileDownloadMonitor: You can add the global monitor for Statistic/Debugging now.
  • FileDownloader#enableAvoidDropFrame(void): Avoid missing screen frames, but this leads to all callbacks of FileDownloadListener do not be invoked at once when it has already achieved.
  • FileDownloader#disableAvoidDropFrame(void): Disable avoid missing screen frames, let all callbacks of FileDownloadListener be invoked at once when it achieve.
  • FileDownloader#isEnabledAvoidDropFrame(void): Has already enabled Avoid Missing Screen Frames. Default: true
  • FileDownloader#setGlobalPost2UIInterval(intervalMillisecond:int): For Avoid Missing Screen Frames. Each intervalMillisecond post 1 message to ui thread at most. if the value is less than 0, each callback will always post a message to ui thread immediately, may will cause missing screen frames and produce great pressure on the ui thread Looper. Default: 10ms.
  • FileDownloader#setGlobalHandleSubPackageSize(packageSize:int): For Avoid Missing Screen Frames. {packageSize}: The number of FileDownloadListener's callback contained in each message. value completely dependent on the intervalMillisecond of setGlobalPost2UIInterval, describe will handle up to {packageSize} callbacks on the each message posted to ui thread. Default: 5.
  • BaseDownloadTask#setSyncCallback(syncCallback:boolean): if true will invoke callbacks of FileDownloadListener directly on the download thread(do not post the message to the ui thread), default false.
  • BaseDownloadTask#isSyncCallback(void):boolean: Whether sync invoke callbacks of FileDownloadListener directly on the download thread.
  • FileDownloadUtils#setDefaultSaveRootPath: The path is used as Root Path in the case of task without setting path in the entire Download Engine.
  • FileDownloadQueueSet: In order to be more convenient to bind multiple tasks to a queue, and to the overall set.

Enhancement

  • Improve Debugging: Provide the FileDownloadMonitor to monitor entire Download Engine.
  • Improve Performance: Optimize EventPool lock & do not handle listener priority any more(no use internal).
  • Improve Performance: Call FileDownloadListener methods do not through EventPool, instead, invoke directly.

Fix

  • Fix: EventPool listener unlimited increased bug.

Version 0.1.5

2016-01-17

New Interfaces

  • BaseDownloadTask#setTag(key:int, tag:Object): Set a tag associated with this task. If the key already existed, the old tag will be replaced.
  • BaseDownloadTask#getTag(key:int): Get the object stored in the task as a tag, or null if not set.
  • BaseDownloadTask#addHeader(name:String, values:String): Add custom request header to the task. Attention: We have already handled ETag, and will add If-Match & Range value if it works.
  • BaseDownloadTask#addHeader(line:String): Add custom request header to the task. Attention: We have already handled ETag, and will add If-Match & Range value if it works.
  • BaseDownloadTask#removeAllHeaders(name:String): Remove all custom request header bind with the {name}.

Enhancement

  • Improve Performance: Reduce the consumption of the generated log.
  • Improve Debugging: To filter all the log level, reduce the high level of log output, and by default, will output Warn、Error、Assert level of log in order to debugging in the case of the value of FileDownloadLog.NEED_LOG is false(default).

Fix

  • Fix can't resume from the break point naturally in case of the download status of the task is Error.
  • Fix the size of the queue may not match the number of actual active tasks in case of high concurrency. This bug may would caused some callbacks to be consumed by the old tasks.

Others

  • Upgrade dependency okhttp from 2.7.1 to 3.0.1.

Version 0.1.4

2016-01-13

New Interfaces

  • FileDownloader#getStatus(downloadId): Get download status by the downloadId(ps: Please refer to Tasks Manager demo
  • FileDownloader#isServiceConnected(void): Whether started and connected to the :filedownloader progress(ps: Please refer to Tasks Manager demo)

Enhancement

  • Supported Chunked transfer encoding data download(Recommend to glance at demo on Single Task Test).
  • Improve Performance: Reduce IPC.
  • Improve Performance: Reduce lock.
  • Improve Performance: Delete invalid datum in db with the :filedownloader progress start.
  • Improve Performance: Ignore the callbackProgressTimes column in db.

Fix

  • Fix FileDownloader#pauseAll not effect in case of low memory and ui progress is Background Progress situation and the :filedownloader progress(Service Progress) alive and still have running tasks in the filedownloader progress but ui progress has died and relived.

  • Handle case of ui progress be killed by sys and download progress not be killed, and ui progress relives and re-executes same tasks queue.
