In this recipe, we will implement generic validation methods to identify the tag format. This way, we can implement different payload handling mechanisms for the content that our application knows to handle, preventing unwanted exceptions.
We will be using the project from the previous recipe, so make sure you have gone through it before starting this one.
In this application, we will be adding some methods to your NfcHelper class to facilitate the identification of the tag content. To do this, perform the following steps:
Open the project files from the Handling tag-writing errors recipe.
Implement the
isTextRecordmethod in theNfcHelperclass with the following code:public boolean isTextRecord(NdefRecord record) { if (record == null) { return false; } return isNdefRecordOfTnfAndRdt(record, NdefRecord.TNF_WELL_KNOWN, NdefRecord.RTD_TEXT); }Implement the
isUrlRecordmethod in theNfcHelperclass:public boolean...
