The SSLContext can then be used with an HTTPUrlConnection to connect to the server: SslContext.init(keyManagers, null, null) SSLContext sslContext = SSLContext.getInstance("TLS") KeyManager keyManagers = kmf.getKeyManagers() Kmf.init(keyStore, clientCertPassword.toCharArray()) KeyManagerFactory kmf = KeyManagerFactory.getInstance("X509") BaseColumns CalendarContract.AttendeesColumns CalendarContract.CalendarAlertsColumns CalendarContract.CalendarCacheColumns CalendarContract. Now that we have the KeyStore containing the client certificate, we can use it to build an SSLContext: KeyStore.load(fis, clientCertPassword.toCharArray()) Connection pooling reduces request latency (if HTTP/2 isn’t.

One of the most common scenario when developing Android HTTP client.
#Android http client download#
Download data from server to Android app. When developing Android HTTP client, GET and POST requests are the base. OkHttp is an HTTP client that’s efficient by default: HTTP/2 support allows all requests to the same host to share a socket. Android HTTP Client: GET, POST, Download, Upload, Multipart Request GET and POST requests in Android HTTP Client. Doing HTTP efficiently makes your stuff load faster and saves bandwidth. KeyStore = KeyStore.getInstance("PKCS12") įis = new FileInputStream(certificateFile) HTTP is the way modern applications network.
#Android http client password#
Once we have a reference to a File containing the client certificate and the password for the certificate, we load it into an appropriate KeyStore (see the sample SSLContextFactory.java): The secret to using our client certificate is setting up a custom KeyStore containing the certificate, and then using it to create a custom SSLContext.

In our final application, we “imported” the certificate by copying it to application-specific storage, and then deleting the original from the sdcard root directory. You can also choose to mount the phone as a disk drive when you plug in the USB cable, and copy the file that way.

If you are using an emulator, you can do the same thing to copy the certificate to the emulator’s sdcard. To give our application access to the certificate, we used the DDMS utility to copy the certificate file to the root directory of the phone’s sdcard. Our client certificate was issued in the PKCS 12 format, as a. One way that you can do this is by using the Apache mod_ssl module.īefore starting out with using HTTP or HTTPS on Android, make sure that your application has permission to access the network by adding the following to your AndroidManifest.xml: You will, of course, have to set up your own HTTPS server and your own server and client certificates. If you want to follow along by trying out the code, it’s available on GitHub. The rest of this post describes how we met those challenges. This presented some interesting challenges. On a recent project, we needed to communicate with an HTTPS server that required client certificates, and which used a self-signed server certificate. Things get interesting, however, once you go past “plain vanilla” HTTPS. Either one can be used, but the official recommendation is to use HttpURLConnection for Gingerbread or later, and HTTPClient for Froyo and earlier. Depending on the version of the Android OS, either HTTPClient or HttpURLConnection just work.

Working with HTTP and HTTPS on Android is generally fairly straightforward and well documented. Depending on the version of the Android OS, either HTTPClient or HttpURLConnection “just work”. Working with HTTP and HTTPS on Android is generally fairly straightforward and well documented. Many Android applications use REST or another HTTP based protocol to communicate with a server. get( 0) ĪsyncConnection asyncConnection2 = asyncConnectionList. 2 is the number of connections you desire to monitor AsyncConnection asyncConnection1 = asyncConnectionList.
