Send File Google Wear To Mobile

I'm trying to send a file from my Google wear to my Nexus 5. I've read some tutorials and came up with the following code but my phone isn't receiving a file. Mobile: private Googl

Solution 1:

add a key value in the datamap: map.put("timestamp", System.currentmillions()) your phone do not receive any change event, because you put the same data item into the data api queue, try to put a different item

Solution 2:

I solved it by replacing this

PutDataRequestputDataRequest= PutDataRequest.create("/image");
putDataRequest.putAsset("debugFile", asset);
Wearable.DataApi.putDataItem(client, putDataRequest);

with this

PutDataMapRequestdataMap= PutDataMapRequest.create("/image");
dataMap.getDataMap().putAsset("debugFile", asset);
PutDataRequestrequest= dataMap.asPutDataRequest();
PendingResult<DataItemResult> pendingResult = Wearable.DataApi.putDataItem(client, request);
pendingResult.setResultCallback(newResultCallback<DataItemResult> () {
    @OverridepublicvoidonResult(DataItemResult dataItemResult) {
        // something 
    }
} );

now it works for me

Solution 3:

Main error:

// Read data from the Asset and write it to a file on external storagefinalFilefile=newFile(dir, "sensordata.txt");
        if (!file.exists()) {
            file.mkdirs(); <---- you create a directory instead a file
        }

and that's why you see not the error.

            fOut.flush();
            fOut.close();
        } catch (Exception e) { <--- hide exception
        }

File exists as directory and a stream can't be open it

FileOutputStreamfOut=newFileOutputStream(file); <-- throw exception
