Sample Code for CamDigiKey Integration with Android

To integrate app-to-app authentication with CamDigiKey app, a client must have an API server which its endpoints communicate with CamDigiKey server using CamDigiKey client library. Then, client mobile application requests to client API server to get loginToken.

1. Login with CamDigiKey:

• Get LoginToken from your own server:
• Handle callback from Login with CamDigiKey:

val resultLauncher = 
    registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result -> 
        if (result.resultCode == Activity.RESULT_OK) { 
            findViewById<TextView>(R.id.tvMessage).text = 
                "Approved: ${result.data.toString()}" 
            val authToken = result.data?.getStringExtra("authToken") 
            Log.d("authToken =", "$authToken") 
            val i = Intent(this, ClientInfoActivity::class.java) 
            val flags = Intent.FLAG_ACTIVITY_CLEAR_TASK or Intent.FLAG_ACTIVITY_NEW_TASK 
            flags.let { i.flags = it } 
 
            i.putExtra("authToken", authToken) 
            startActivity(i) 
        } else { 
            findViewById<TextView>(R.id.tvMessage).text = 
                "Rejected: ${result.data.toString()}" 
        } 
    } 

2. Setup Login with CamDigiKey on your activity:

findViewById<Button>(R.id.btSendRequest).setOnClickListener { 
    getLoginToken() 
    Log.d("LoginToken", "${loginToken}") 
    val intent = Intent(Intent.ACTION_ASSIST).apply { 
        data = Uri.parse("camdigikey://login?token=${loginToken}") 
        setPackage("kh.gov.camdx.camdigikey.debug") 
        putExtra(Intent.EXTRA_ASSIST_PACKAGE, BuildConfig.APPLICATION_ID ) 
    } 
 
    try { 
        resultLauncher.launch(intent) 
    } catch (e: Exception) { 
        Toast.makeText(this, "Please install camDigiKey app", Toast.LENGTH_SHORT).show() 
    } 
}
