How do I tell the TLS version in Android Volley
android, android-volley, https, ssl, sslsocketfactory
Solution
You may modify the version of TLS used in Volley by creating a custom HTTPStack and setting the stack in the `Volley.newRequestQueue(context, httpStack)` method in Volley.java. Although, you only need to do this for Android versions 16-19. Before v16, TLS 1.2 isn't supported and after v19, TLS 1.2 is enabled by default. So, you should focus on manually setting TLS to 1.2 for Android versions 16-19.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN
&& Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {
try {
ProviderInstaller.installIfNeeded(getContext());
} catch (GooglePlayServicesRepairableException e) {
// Indicates that Google Play services is out of date, disabled, etc.
// Prompt the user to install/update/enable Google Play services.
GooglePlayServicesUtil.showErrorNotification(e.getConnectionStatusCode(), getContext());
// Notify the SyncManager that a soft error occurred.
syncResult.stats.numIOExceptions++;
return;
} catch (GooglePlayServicesNotAvailableException e) {
// Indicates a non-recoverable error; the ProviderInstaller is not able
// to install an up-to-date Provider.
// Notify the SyncManager that a hard error occurred.
syncResult.stats.numAuthExceptions++;
return;
}
HttpStack stack = null;
try {
stack = new HurlStack(null, new TLSSocketFactory());
} catch (KeyManagementException e) {
e.printStackTrace();
Log.d("Your Wrapper Class", "Could not create new stack for TLS v1.2");
stack = new HurlStack();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
Log.d("Your Wrapper Class", "Could not create new stack for TLS v1.2");
stack = new HurlStack();
}
requestQueue = Volley.newRequestQueue(context, stack);
} else {
requestQueue = Volley.newRequestQueue(context);
}
And then use a TLSSocketFactory class which extends SSLSocketFactory like the one Florian Krauthan created here, where the v1.2 TLS protocol is enabled: https://gist.github.com/fkrauthan/ac8624466a4dee4fd02f#file-tlssocketfactory-java
Problem
My project has been using Android Volley network framework for a long time, but recently I found a SSL 3.0 protocol bug published on the Internet. I want to know how can I find out what's the TLS version my project used, and how to confirm whether the library is updated. Here is my source code fragment: ``` HttpStack stack = new HurlStack(); Network network = new BasicNetwork(stack); mHttpRequestQueue = new RequestQueue(new NoCache(), network); mHttpRequestQueue.start(); ``` I think the point is in HurlStack class, and it depends on `org.apache.http` package, but I can't figure out where TLS/SSL configuration is.
