+# MetaPlugin Demo Android
+
+This project demonstrates how to embed the WebID Meta Plugin into an Android App.
+The code of the project is described with comments on how to use it.
+
+## Tutorial
+
+To start the plugin in this example project, open the gradle.properties file.
+You will find empty credential properties at the bottom.</br>
+You should have been given a username and a password to access your environment.</br>
+Navigate to the ~/.gradle/gradle.properties file on your system..
+If it does not exist, create it.</br>
+Enter the properties for your preferred platform.
+
+To begin the identification process, you will need to create it outside the app.</br>
+From the process creation request to the server, you should have received an action-id, consisting of 9 numbers.
+
+After that, open the MainActivity.kt file and finish the three TODOs at the top.
+<ol>
+    <li>choose video call configs</li>
+    <li>insert your 9-digit action id</li>
+    <li>choose an environment to use</li>
+</ol>
+
+After that, start the demo app on an android device.</br>
+Press the main button to start the plugin at runtime.
+
+
+## Fastened Tutorial
+
+<ol>
+    <li>Add usernames and passwords in your ~/.gradle/gradle.properties file</li>
+    <li>Create a transaction via backend API</li>
+    <li>Set video-call configs in MainActivity.kt</li>
+    <li>Replace placeholder string of action-id in MainActivity.kt with action-id from process-creation response</li>
+    <li>Choose environment in MainActivity.kt</li>
+    <li>Start this app on a test device</li>
+    <li>Click main button to start the plugin at runtime</li>
+</ol>
+
+
+## Additional Notes
+
+On Samsung Devices, configurations should be changed.
+In MainActivity.kt, go to 
+<pre><code>private val config = VideoOptionsConfig(true, false, false)</code></pre>
+and set the booleans according to the chapter
+
+>The VideoOptionsConfig object
+
+in the Integration Guide.
+
+
+## Theming (Optional)
+
+The plugin implemented in this project supports customized theming.</br>
+To try out different themes, go to the file src/main/res/values/themes.xml and add items to the following element:
+
+```
+<style name="CustomizedPluginTheme" parent="WebId.PluginTheme.Light">
+</style>
+```
+
+Consult the theming guide to see what items can be changed.</br>
+To change the Dark mode theming, navigate to the file src/main/res/values-night/themes.xml and add items to the following element:
+
+```
+<style name="CustomizedPluginTheme" parent="WebId.PluginTheme.Dark">
+</style>
+```
