-IR decode example for Android application
 
-Please refer to the usage documents in /decodesdk
+This project shows how can you develop an Android APP remote controller quickly.
 
+The key components of the Android remote example includes:
+
+## The Cloud-SDK
+The Cloud SDK calls the Rest API provided by the IRext index service to complete the APP login and
+help use indexing targeted remote controller from category to remote index.
+
+To import the Android Cloud SDK, add following line to the build.gradle for the APP
+
+```
+implementation 'net.irext.webapi:irext-androidapi:1.5.2
+```
+
+And then add the meta-data in your AndroidManifest.xml to make the Cloud SDK login to the indexing server for the access token
+
+```xml
+
+<meta-data
+    android:name="irext_app_key"
+    android:value="c49c3bd5ff6b3efb67d8af2c" />
+
+<meta-data
+    android:name="irext_app_secret"
+    android:value="194f9cb578c458ace2284f16" />
+```
+
+Follow the examples of calling `mApp.mWeAPIs` in corresponding UI flows in order to find the targeted remote index, download the remote control binary file.
+
+## Use Mobile Phone as Remote Control
+After the remote index binary code is downloaded, you can see the remote control panel,
+by pressing control buttons, the binary code would be decoded into IR timing series. If you have an Android phone with IR transmitter, 
+you can send the 38KHz infra-red waves directly to control the home appliances.
+
+As a reference, you need to integrate the IR decode library, see the shared libraries in jniLibs directory into your project.
+
+By calling API provided by the decode library in order to open and decode remote control binary files into infra-red timing series:
+
+```java
+
+```
+
+## Working with Arduino Remote Control <img src='app/src/main/res/mipmap-xxhdpi/button_link.png' style='padding-top: 12px; height: 32px; width: 20px;'>
+There is another example project <a href='https://opensource.irext.net/irext/examples/-/tree/master/arduino-example'>arduino-example</a> which can be co-worked with this
+Android APP remote controller.
+
+
+Well by connecting to the Arduino controller with IP address in the same LAN, the Android APP can send the downloaded remote control binary to it, 
+and then pass the remote control command by pressing buttons accordingly. The Arduino remote controller would decode the IR time series instead and send the
+38KHz infra-red carrier waves to home appliances.
