Key hash for Android-Facebook app in Kotlin Programmatically

Question

I'm trying to get the hash key in kotlin for facebook-app before that i use this java method to get hask key for my apps:

Java code:

// Add code to print out the key hash
    try {
        PackageInfo info = getPackageManager().getPackageInfo(
                "your.package", 
                PackageManager.GET_SIGNATURES);
        for (Signature signature : info.signatures) {
            MessageDigest md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
            }
    } catch (NameNotFoundException e) {

    } catch (NoSuchAlgorithmException e) {

    }

Now i tried this code snippet by converting it into kotlin code:

Kotlin Code:

    try {
           val info = packageManager.getPackageInfo(packageName, PackageManager.GET_SIGNATURES)
            for (signature in info.signatures) {
                val md = MessageDigest.getInstance("SHA")
                md.update(signature.toByteArray())
                Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT))
            }
    } catch (e: PackageManager.NameNotFoundException) {
                    e.printStackTrace()
    } catch (e: NoSuchAlgorithmException) {
                    e.printStackTrace()
    }

but getting error on this line of code i have tried some solutions but didn't get anything useful:

      Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT))

encodeToString is unresolved and same for Base64.DEFAULT.

Thanks in advance for your time.

Answer 1

Use below code for getting keyhash

try {
        val info = packageManager.getPackageInfo(
                "your package",
                PackageManager.GET_SIGNATURES)
        for (signature in info.signatures) {
            val md = MessageDigest.getInstance("SHA")
            md.update(signature.toByteArray())
            Log.e("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT))
        }
    } catch (e: PackageManager.NameNotFoundException) {

    } catch (e: NoSuchAlgorithmException) {

    }

Make sure that. You import correct packages

   import android.content.pm.PackageManager
import android.util.Base64
import android.util.Log
import java.security.MessageDigest
import java.security.NoSuchAlgorithmException

Nothing wrong in your code only one change needed Please add import android.util.Base64 instead of import java.util.*
