| Methods Summary |
|---|
| public boolean | canUseNetwork(boolean available, boolean roaming)Returns whether this download is allowed to use the network.
if (!available) {
return false;
}
if (destination == Downloads.DESTINATION_CACHE_PARTITION_NOROAMING) {
return !roaming;
} else {
return true;
}
| | public boolean | hasCompletionNotification()Returns whether this download has a visible notification after
completion.
if (!Downloads.isStatusCompleted(status)) {
return false;
}
if (visibility == Downloads.VISIBILITY_VISIBLE_NOTIFY_COMPLETED) {
return true;
}
return false;
| | public boolean | isReadyToRestart(long now)Returns whether this download (which the download manager has already seen
and therefore potentially started) should be restarted.
In a nutshell, this returns true if the download isn't already running
but should be, and it can know whether the download is already running
by checking the status.
if (control == Downloads.CONTROL_PAUSED) {
// the download is paused, so it's not going to restart
return false;
}
if (status == 0) {
// download hadn't been initialized yet
return true;
}
if (status == Downloads.STATUS_PENDING) {
// download is explicit marked as ready to start
return true;
}
if (status == Downloads.STATUS_RUNNING_PAUSED) {
if (numFailed == 0) {
// download is waiting for network connectivity to return before it can resume
return true;
}
if (restartTime() < now) {
// download was waiting for a delayed restart, and the delay has expired
return true;
}
}
return false;
| | public boolean | isReadyToStart(long now)Returns whether this download (which the download manager hasn't seen yet)
should be started.
if (control == Downloads.CONTROL_PAUSED) {
// the download is paused, so it's not going to start
return false;
}
if (status == 0) {
// status hasn't been initialized yet, this is a new download
return true;
}
if (status == Downloads.STATUS_PENDING) {
// download is explicit marked as ready to start
return true;
}
if (status == Downloads.STATUS_RUNNING) {
// download was interrupted (process killed, loss of power) while it was running,
// without a chance to update the database
return true;
}
if (status == Downloads.STATUS_RUNNING_PAUSED) {
if (numFailed == 0) {
// download is waiting for network connectivity to return before it can resume
return true;
}
if (restartTime() < now) {
// download was waiting for a delayed restart, and the delay has expired
return true;
}
}
return false;
| | public long | restartTime()Returns the time when a download should be restarted. Must only
be called when numFailed > 0.
if (retryAfter > 0) {
return lastMod + retryAfter;
}
return lastMod +
Constants.RETRY_FIRST_DELAY *
(1000 + Helpers.rnd.nextInt(1001)) * (1 << (numFailed - 1));
| | public void | sendIntentIfRequested(android.net.Uri contentUri, android.content.Context context)
if (pckg != null && clazz != null) {
Intent intent = new Intent(Downloads.DOWNLOAD_COMPLETED_ACTION);
intent.setClassName(pckg, clazz);
if (extras != null) {
intent.putExtra(Downloads.NOTIFICATION_EXTRAS, extras);
}
// We only send the content: URI, for security reasons. Otherwise, malicious
// applications would have an easier time spoofing download results by
// sending spoofed intents.
intent.setData(contentUri);
context.sendBroadcast(intent);
