I bought this fingerprint module from a web. And i get its library from adafruit and its working fine.
The problem is that i dont know know to link it to my android app. I want to make a fingerprint matching feature to my app. Which when the fingerprint module read a fingerprint that already saved , it send to the app that it reed a fingerprint that its identical to one of the fingerprints that is stored in its memory and its the fingerprint of a spicefic person.
Why didn't you buy the module from Adafruit, if you plan to use Adafruit's library?

That would be because "linking it to your Android app" doesn't make sense.

Since the fingerprint database is on the fingerprint module, and the fingerprint module has already determined if it recognizes the scanned fingerprint, and, if so, which ID is associated with that fingerprint, it is not at all clear what the Android app is going to do.

Well, that's useless information.

For now i need an arduino code to send a text to an andriod application through hc 05 module.
PaulS:
You haven't told us how the HC05 module is connected to the Arduino, so, we can't tell you how to send serial data to it.
Im using an arduino uno with the hc05 ...
I searched the net of how i send the data i cant find exactlty what i want...
Its not a big deal of how the pins of hco5 ( Rx . Tx ) are connected to, i can configure them from the code.

Bullshit. That you did not recognize what you needed to do might be true. That you did not find pre-written code that said that it did exactly what you want may be true. That you could not dind anthing that said that the device takes serial data, so you need to use Serial.print(), Serial.write(), or Serial.println(), or the corresponding methods in the SoftwareSerial class is NOT true.

It IS important to know if they are connected to pins 0 and 1, where you use Serial to talk to it, or other pins, where you need to create an instance of SoftwareSerial, and use that instance to talk to it.
PaulS:
And duct tape to hold them together?

I cant find anything you wrote is helpful ...
I came here to ask for a simple code to send a simple text to an andriod application, not to learn how to program...
Thank you for replying but you waisting my time and your time...
