Launch Specific App when NFC is discovered


Launch Specific App when NFC is discovered

I wish this helpful for you The reason why you get an intent chooser is that multiple activities are registered for the data type text/plain. This is a rather common case and you should therefore avoid using such generic data types for the NDEF record that should launch your activity. You have two options to overcome this problem:
code :
NdefRecord extRecord = NdefRecord.createExternal(
        "yourdomain.com",  // your domain name
        "yourtype",        // your type name
        textBytes);        // payload
<activity ...>
    <intent-filter>
        <action android:name="android.nfc.action.NDEF_DISCOVERED" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:scheme="vnd.android.nfc" android:host="ext"
              android:pathPrefix="/yourdomain.com:yourtype" />
    </intent-filter>
</activity>
NdefRecord appRecord = NdefRecord.createApplicationRecord(
        "com.yourdomain.yourapp");
NdefRecord textRecord = NdefRecord.createTextRecord(
        "en",       // language code
        "yourtext"  // human-readable text);
NdefMessage msg = new NdefMessage(
        textRecord,
        appRecord);  // use the AAR as the *last* record in your NDEF message

like below fixes the issue I simply unload the project until I want to run the tests.
Which projects are unloaded are saved in the .suo file, which can be excluded from source control if your lab build is being done automatically, or you can reload in manually if your lab building is created manually.

wish help you to fix your issue Here's a minimal example. I would like to show only rows for which a particular element is empty. Here's what the Excel Macro generator gives me. , UsedRange revers to the range of your worksheet which contains data:

Hope this helps When you scan for CBPeripheral objects, the peripheral service UUID is obtained from the advertisement packet. The peripheral is basically saying, "Oh yeah, I have this service UUID!" iOS picks that up and passes the CBPeripheral to you.
But the peripheral might not be synced with what is in the advertisement packet. It's a non-binding agreement that the advertisement packet matches what's actually in the peripheral's service/characteristic hierarchy.

this will help I think Larme has already given the appropriate solution, but I will formulate it as an answer instead of a comment because the comment was probably overlooked.
You scan for peripherals that expose a specific service in their advertisement data. That means that the whole string 00001803-494c-4f47-4943-544543480000 has to be part of the advertisement data. If there is no device found, but if it works for 1803, it seems that only 1803 is broadcasted by the devices as service information.

it fixes the issue I'm trying to create a batch file that will discovered the location of a EXE in this case Steam, and runs that EXE with the discovered path from the registry. The reason I want to discover the install path via the registry is because this batch file is to run over multiple machines and the Steam install paths could be different.
