I wish to do some batch upload of attachments... (attachments are uploaded when the user has a good network coverage)So as is typically done I created a background thread so as not to block the UI.But I find that the Esri Android SDK Upload Attachments function uses callbacks - which makes uploading more than 1 attachment difficult - Is there any easy way to block the background processing thread at the point ({1}) until ArcGISFeatureLayer::addAttachment() returns with a result- to make my function ESRI_SDKAttachmentAddLive work like calling the org.apache.commons.httpclient post functions directly would? Thanks all. @Override protected Message /*AsyncTask::*/doInBackground(String... params)
{
....
private void ESRI_SDKAttachmentAddLive(String sURLBase, AttachInfo attachInfo, String sFeatureObjectID)
{ //this is now in a non-ui thread.
//issue - No blocks here -so will continue to run....not ideal for batch upload of images
try
{
final ArcGISFeatureLayer fl = new ArcGISFeatureLayer(sURLBase, MODE.SNAPSHOT);
File file = new File(attachInfo.mFilename);
//Note: fl.addAttachment will strip off the path for us
fl.addAttachment(Integer.valueOf(sFeatureObjectID), file, "image/jpeg", new CallbackListener<FeatureEditResult>()
{
@Override public void onCallback(FeatureEditResult arg0)
{ //FeatureEditResult [objectId=2801, globalId=null, success=true, error=null]
Log.d(Utils.tag,"Image Uploaded OK");
{2}
}
@Override public void onError(Throwable arg0)
{
Log.e(Utils.tag,"Error: "+arg0.getMessage());
{3}
}
} );
}
catch(Exception ex)
{
ex.printStackTrace();
Log.e(Utils.tag,ex.getMessage());
}
//{1}want to block at this point - until we have a callback (good or bad) from the fl.addAttachment call
}
