InputStream inputStream = getClass().getResourceAsStream("cert.bks"); //The converted bks certificate
You should put your cert.bks file into /res/raw directory, then open the file with getResources().openRawResource(R.raw.cert);.
EDIT:
I think you are not specifying the provider when you are loading the truststore.
KeyStore keyStore = KeyStore.getInstance("BKS", BouncyCastleProvider.PROVIDER_NAME);
And if you forgot, you need to add the SpongyCastle provider in your Application class.
public class CustomApplication
extends Application {
static {
Security.insertProviderAt(new BouncyCastleProvider(), 1);
}
And add that to your AndroidManifest.xml
<application
android:allowBackup="true"
android:name=".application.CustomApplication"
But if that still doesn't work, what you can try to do is adding the following classes from the source of Apache HttpClient (it's apache-licensed so you can do that):

Once you add these, you can build your SSLContext like so:
SSLContextBuilder sslContextBuilder = SSLContextBuilder.create();
KeyStore keyStore = KeyStore.getInstance("BKS", BouncyCastleProvider.PROVIDER_NAME);
android.content.res.Resources res = <getter for resources>;
InputStream inputStream = res.openRawResources(R.raw.cert);
keyStore.load(inputStream, trustStorePassword);
sslContextBuilder.loadTrustMaterial(keyStore, trustStorePassword);
SSLContext sslContext = sslContextBuilder.build();
//okHttpClient.setSslSocketFactory(sslContext.getSocketFactory());
EDIT: Testing certificate
keyStore.load(byteArrayInputStream, keyStorePassword);
Certificate[] certificates = keyStore.getCertificateChain("key-alias"); //you need to know the alias
if(certificates.length > 0) {
Certificate certificate = certificates[0];
X509Certificate x509Certificate = (X509Certificate) certificate;
Log.d(TAG,
"Certificate found with DN [" + x509Certificate.getSubjectDN() + "]");
