What method to add for my NearablesDemoActivity.java

BLE Beacons

I have error at dbRow = stickerdb.getResult(currentNearable.identifier(“065473d63cd9d687”));
It says Method call expected

The error log:
Error:(96, 52) error: cannot find symbol method identifier(String)

Hi @Jaemin_Sung,

When you have scanned Nearables in your vicinity, do use Nearable#identifier property in order to get nearable’s identifier.

Hi @wiktor
What do you mean by using Nearable#identifier property?

@Jaemin_Sung
Hi Jaemin, Can you please provide me your source code of nearable. I am also working on it so I can get some basic support from your code.
Thanks in advance.

You’re calling an identifier method on an object of the Nearable class. There is no such android method in this class:
http://estimote.github.io/Android-SDK/JavaDocs/com/estimote/sdk/Nearable.html
There is, however, an identifier property, and that’s the one you need to use:
http://estimote.github.io/Android-SDK/JavaDocs/com/estimote/sdk/Nearable.html#identifier
In other words, this line:
dbRow = stickerdb.getResult(currentNearable.identifier(“065473d63cd9d687”));
… needs to become:
dbRow = stickerdb.getResult(currentNearable.identifier);
