Self signed certificates are always a problem in Android. You can try this:

I faced this issue yesterday, while migrating our company's RESTful API to HTTPS, but using self-signed SSL certificates.

I've looking everywhere, but all the "correct" marked answers I've found consisted of disabling certificate validation, clearly overriding all the sense of SSL.

I finally came to a solution:

Create Local KeyStore

To enable your app to validate your self-signed certificates, you need to provide a custom keystore with the certificates in a manner that Android can trust your endpoint.

The format for such custom keystores is "BKS" from BouncyCastle, so you need the 1.46 version of BouncyCastleProvider that you can download here.

You also need your self-signed certificate, I will assume it's named self_cert.pem.

Now the command for creating your keystore is:

<!-- language: lang-sh -->

$ keytool -import -v -trustcacerts -alias 0 \
-keystore *PATH_TO_KEYSTORE* \
-storetype BKS \
-provider org.bouncycastle.jce.provider.BouncyCastleProvider \
-providerpath *PATH_TO_bcprov-jdk15on-146.jar* \
-storepass *STOREPASS*

PATH_TO_KEYSTORE points to a file where your keystore will be created. It MUST NOT EXIST.

PATH_TO_bcprov-jdk15on-146.jar.JAR is the path to the downloaded .jar libary.

STOREPASS is your newly created keystore password.

Include KeyStore in your Application

Copy your newly created keystore from PATH_TO_KEYSTORE to res/raw/certs.bks (certs.bks is just the file name; you can use whatever name you wish)

Create a key in res/values/strings.xml with

<!-- language: lang-xml -->

<string name="store_pass">*STOREPASS*</string>

Create a this class that inherits DefaultHttpClient

import android.content.Context;
import android.util.Log;
import org.apache.http.conn.scheme.PlainSocketFactory;
import org.apache.http.conn.scheme.Scheme;
import org.apache.http.conn.scheme.SchemeRegistry;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.params.HttpParams;

import java.io.IOException;
import java.io.InputStream;
import java.security.*;

public class MyHttpClient extends DefaultHttpClient {

private static Context appContext = null;
private static HttpParams params = null;
private static SchemeRegistry schmReg = null;
private static Scheme httpsScheme = null;
private static Scheme httpScheme = null;
private static String TAG = "MyHttpClient";

public MyHttpClient(Context myContext) {

appContext = myContext;

if (httpScheme == null || httpsScheme == null) {
httpScheme = new Scheme("http", PlainSocketFactory.getSocketFactory(), 80);
httpsScheme = new Scheme("https", mySSLSocketFactory(), 443);



private SSLSocketFactory mySSLSocketFactory() {
SSLSocketFactory ret = null;
try {
final KeyStore ks = KeyStore.getInstance("BKS");

final InputStream inputStream = appContext.getResources().openRawResource(R.raw.certs);

ks.load(inputStream, appContext.getString(R.string.store_pass).toCharArray());

ret = new SSLSocketFactory(ks);
} catch (UnrecoverableKeyException ex) {
Log.d(TAG, ex.getMessage());
} catch (KeyStoreException ex) {
Log.d(TAG, ex.getMessage());
} catch (KeyManagementException ex) {
Log.d(TAG, ex.getMessage());
} catch (NoSuchAlgorithmException ex) {
Log.d(TAG, ex.getMessage());
} catch (IOException ex) {
Log.d(TAG, ex.getMessage());
} catch (Exception ex) {
Log.d(TAG, ex.getMessage());
} finally {
return ret;

Now simply use an instance of **MyHttpClient** as you would with **DefaultHttpClient** to make your HTTPS queries, and it will use and validate correctly your self-signed SSL certificates.

HttpResponse httpResponse;

HttpPost httpQuery = new HttpPost("https://yourserver.com";);
... set up your query ...

MyHttpClient myClient = new MyHttpClient(myContext);


httpResponse = myClient.(peticionHttp);

// Check for 200 OK code
if (httpResponse.getStatusLine().getStatusCode() == HttpURLConnection.HTTP_OK) {
... do whatever you want with your response ...

}catch (Exception ex){
Log.d("httpError", ex.getMessage());
