I found a solution to your problem on github which should ease your efforts to a great way:
This is the sample application for the
Liferay Android SDK.
It's a simple app that displays users in a table view. By clicking on a user, it will display its contact details such as name, email, birthday and phones. By default, it uses the following credentials to authenticate:
Email: test@liferay.com; password: test; server: http://10.0.2.2:8080.
You can change these values in the
SettingsUtil.java class.
Most of the interesting code are in
MainActivity.java and
DetailsActivity.java . In these classes you can see how to create sessions and call portal services.
If you want to make asynchronous requests, take a look on how
ContactCallback.java is used. If you have an existing AsyncTask and want to use that to make services calls, take a look at
UsersAsyncTask.java.
Import into your IDE
Android Studio
Click on Import Project…
Choose buid.gradle from the root folder
And that's it, Android Studio should automatically use Gradle Wrapper and create a local.properties file for you.
Build
This project uses Gradle as the build and dependency management system. If you don't want to use Gradle, you can download the Android SDK JAR and its dependencies and copy them to your project's /libs folder, follow the instructions described
here.
In order to build with Gradle, you have to:
Create a local.properties files with a sdk.dir= property pointing to your Android SDK folder.
Run $ ./gradlew build from the project root folder. This will automatically download the Android SDK and dependencies for you.
There are many more useful tasks, for example, for running your project in an emulator or device. Run $ ./gradlew tasks to see which tasks are available.
For more information on how the Android Gradle plugin works, read their
documentation and more on Android programming you can refer these
tutorials.
