Create a basemap from a tiled service (download a basemap) Example

Anonymous User

OK I am trying to use the example to build an offline tpk from a tiled service.

https://developers.arcgis.com/en/android/guide/create-an-offline-map.htm#ESRI_SECTION1_286D33A9E13C4BFDA57428D9A0B88D22

There are not good examples so I am trying to follow the example from ArcGIS Runtime and adjust it to ArcGIS Runtime for Android.

https://developers.arcgis.com/en/java/sample-code/download-tile-cache-beta/

The problem I appear to be having is on the CallbackListener.

The line where the issue seems to be happening is new CallbackListener<TileCacheStatus>() {
where I get the following error....

"java.io.FileNotFoundException: /1029171819/TileCacheStatus:

The code is below.... Any thoughts on what I am doing wrong here.

Envelope extent = new Envelope (-13656926.435, 5702260.809, -13655933.12, 5703167.369);
boolean createAsTilePackage = true;
        // fix this to 5 levels
        double[] levels = {0, 1, 2, 3, 4};

     GenerateTileCacheParameters params = new GenerateTileCacheParameters(
             createAsTilePackage,
             levels,
             ExportBy.ID,
             extent,
             mMapView.getSpatialReference());
tileCacheTask = new TileCacheTask("http://tiledbasemaps.arcgis.com/arcgis/rest/services/World_Street_Map/MapServer", null);

tileCacheTask.submitTileCacheJobAndDownload(
               // parameters
               params,
               // status callback
               new CallbackListener<TileCacheStatus>() {
                 private boolean errored = false;

                 @Override
                 public void onError(Throwable e) {
                   errored = true;
                   //updateProgressBarUI(null, false);
                   e.printStackTrace();
                 }

                 @Override
                 public void onCallback(TileCacheStatus status) {
                   if (!errored) {
                    // updateProgressBarUI("Latest status: "+status.getStatus(), true);
                   }
                 }
               },
               // callback when download complete
               new CallbackListener<String>() {
                 private boolean errored = false;

                 @Override
                 public void onError(Throwable e) {
                   errored = true;
                  // updateProgressBarUI(null, false);
                   e.printStackTrace();
                 }

                 @Override
                 public void onCallback(String path) {
                   if (!errored) {

                    // switchToLocalLayer(path);
                    // updateProgressBarUI(null, false);
                     //tpkButton.setEnabled(true); // re-enable button for another job
                   }
                 }
               },

No. I´m just testing a code. This feature only works after the app was licenced ?

You do not need to license your app to use API in developer mode.

I try to run this code with runtime 10.2.3 (using the new ExportTileCacheTask class instead TileCacheTask) but I got the error below

com.esri.core.io.EsriSecurityException: Unauthorized access to a secure service - http://tiledbasemaps.arcgis.com/arcg...iles/submitJob

You need to generate a token to use this service.

When I wrote the code above it did not require credentials. However that changed, so now you must have the code as follows...

UserCredentials credentials;
    credentials = new UserCredentials();
      credentials.setUserAccount(username, password);

    tileCacheTask = new ExportTileCacheTask("http://tiledbasemaps.arcgis.com/arcgis/rest/services/World_Street_Map/MapServer", credentials);

Do you License your app at the Basic level?

Hello,

I try to run this code with runtime 10.2.3 (using the new ExportTileCacheTask class instead TileCacheTask) but I got the error below

com.esri.core.io.EsriSecurityException: Unauthorized access to a secure service - http://tiledbasemaps.arcgis.com/arcgis/rest/services/World_Street_Map/MapServer/exportTiles/submitJob

The same error has ocurred when I try to run the OfflineTiledLayer example from Java SDK.

Anyone knows what is wrong ?

Thank´s

Lisandro

Dan, Thanks for the assistance. I was able to get my code to successfully cache. For anyone interested here is the code that worked for me. Will definitely need to add a progress bar as the download itself can take awhile. Will probably need to restrict this tool based on the estimated cache size.

We are working currently working on a sample for Android and will make it available on ArcGIS Online when it is complete. Below is some working code for creating the tiles locally by calling submitTileCacheJobAndDownload.

 
/**
* Creates tile Cache locally by calling submitTileCacheJobAndDownload
*
* @param params
* @param tileCacheTask
* @param tileCachePath
*/
private void createTileCache(GenerateTileCacheParameters params,
final TileCacheTask tileCacheTask, final String tileCachePath) {

  // Set the recovery directory for incomplete tasks
  tileCacheTask.setRecoveryDir(recoveryDir);

  // estimate tile cache size

  tileCacheTask.estimateTileCacheSize(params,
  new CallbackListener<Long>() {

  @Override
  public void onError(Throwable e) {
    Log.d("*** tilecachesize error: ", "" + e);
  }

  @Override
  public void onCallback(Long objs) {
    Log.d("*** tilecachesize: ", "" + objs);

  }
});

// Submit tile cache job and download

tileCacheTask.submitTileCacheJobAndDownload(params, null,
  new CallbackListener<String>() {
    private boolean errored = false;

    @Override
    public void onError(Throwable e) {
      errored = true;
      // print out the error message and disable the progress bar
      Log.d("*** submitTileCacheJobAndDownload error: ", "" + e);
      mProgress.setVisibility(View.GONE);
    }

    @Override
    public void onCallback(String path) {
      if (!errored) {
        Log.d("the Download Path = ", "" + path);
        // Disable the progress bar and switch to the
        // successfully downloaded local layer
        mProgress.setVisibility(View.GONE);
        switchToLocalLayer(path);
     }
    }
}, tileCachePath);

// recover all incomplete jobs contained in the recovery directory
tileCacheTask.recoverAllJobs(new CallbackListener<TileCacheStatus>() {

@Override
public void onError(Throwable e) {
  Log.d("*** recoverAllJobs error: ", "" + e);
  mProgress.setVisibility(View.GONE);
}

@Override
public void onCallback(TileCacheStatus objs) {
  Log.d("***", " start recovery" + objs);
  }
}, new CallbackListener<String>() {

@Override
public void onError(Throwable e) {
  mProgress.setVisibility(View.GONE);
}

@Override
public void onCallback(String objs) {
  Log.d("***", " end recovery" + objs);
  mProgress.setVisibility(View.GONE);

});
