ThingSpeakAndroid

Unofficial ThingSpeak API library for Android.

Features

Convenient access to ThingSpeak API
Support for TalkBack API
Asynchronous data fetching using Retrofit
Customizable charting based on HelloCharts for Android

Download

ThingSpeakAndroid is available on the jCenter repository. If you are using Android Studio, you can simply add a dependency on your app module's build.gradle file to import this library.

dependencies {

  compile 'com.macroyau:thingspeakandroid:0.2.1' 
}

Please add the following lines to the build.gradle file if Android Studio fails to resolve the jCenter repository.

repositories {

  maven {

url "http://dl.bintray.com/macroyau/maven"
  
}
 
}

Usage

Using ThingSpeakAndroid is extremely easy. Create a ThingSpeakChannel, set an event listener and load the data!

ThingSpeakChannel tsChannel = new ThingSpeakChannel(CHANNEL_ID);
 tsChannel.setChannelFeedUpdateListener(new ThingSpeakChannel.ChannelFeedUpdateListener() {

  @Override
  public void onChannelFeedUpdated(long channelId, String channelName, ChannelFeed channelFeed) {

// Make use of your Channel feed here!
  
}
 
}
);
 tsChannel.loadChannelFeed();

If you want to connect to a private Channel, you need to provide a valid Read API Key.

ThingSpeakChannel tsPrivateChannel = new ThingSpeakChannel(CHANNEL_ID, READ_API_KEY);

You can also create a line chart of a specific Channel field using HelloCharts for Android.

LineChartView chartView = (LineChartView) findViewById(R.id.chart);
 tsChart = new ThingSpeakLineChart(CHANNEL_ID, FIELD_ID);
 tsChart.setListener(new ThingSpeakLineChart.ChartDataUpdateListener() {

  @Override
  public void onChartDataUpdated(long channelId, int fieldId, String title, LineChartData lineChartData, Viewport maxViewport, Viewport initialViewport) {

chartView.setLineChartData(lineChartData);

chartView.setMaximumViewport(maxViewport);

chartView.setCurrentViewport(initialViewport);

  
}
 
}
);
 tsChart.loadChartData();

Please read the API documentation and sample app source code for further details. Sample for TalkBack is coming soon.
