      Android Things

      Android Things applications running on Raspberry Pi 3. Android Things lets you build professional without previous knowledge of embedded system design. Google killed the project for the public on Feb. 2019. The last update is dated on Aug. 2019.

      Android Things Dashboard shutdown will begin on January 5, 2021. After January 5, 2022, Android Things Dashboard will be shut down completely and all remaining data will be deleted.

      #ProjectDIVA: Arduino Mini Pro

      Android Things | 2 min | 2442

      This article extends the node tree of ProjectDiva to include an Arduino Pro Mini.

      This article explains how to connect a Arduino Pro Mini to the nRF24Things application (Android Things). The code allows sending and receiving messages between the nodes. It uses the well-known nRF24 libraries to create a sensor mesh, where the node 0 (in this case a Raspberry Pi running the Android Things application) actuates as a "DHCP" server and assigns the node addresses in the mesh.

      #TI: SensorTag working on Android 8.1

      Android Things | 1 min | 1845

      Thanks Sal for your comments on the article TI: Sensortag CC2650 . This is for you and those who are playing with TI SensorTag!

      I've updated the repository of the Texas Instrument (TI) SensorTag CC2650. The repository can be found here . As you may know TI doesn't update the repository anymore. The original last open source repository of the application can be found here .

      I've wrote an article last year as I migrated and updated the repository:

      Today, I've updated the repository to support Android 8.1 (>6.0). The main modification was that Android >6.0 needs locatio...

      #ProjectDIVA: Android Things 0.8.1 getting started

      Android Things | 3 min | 1509

      After the Hannover Fair 2018, I have this weekend some time and I decided to update the #ProjectDIVA to the last version of Android Things. Today the actual version is 0.8.1 DP and the Android Things Setup Utility has the version number 1.0.19.

      I have two applications running on Android Things:

      In Oct. 2017, I wrote a tutorial for Android Things, but I checked that the tutorial needed an update, and the repositories too. That's why I'm writing this post.

      #ProjectDIVA: nRF24Things working on Android Things DP5.1

      Android Things | 1 min | 671

      I've updated the code of the nRF24Things application. The application is now working on Android Things DP5.1. There is a Bug on DP5.1 related to the SPI units. You can read more on my last post here.

      I've tried to update the SensorTag-Things application but I didn't work. DP5.1 has still problems with Bluetooth. Due to the crash by debugging, I found and reported another bug to Google. Read here.

      Android Things | 5 min | 2915

      As the title says, this is a getting started with Android Things. It should be my first post, but, it's better now than never. I'm posting this to summarize the steps to install Android Things on your Raspberry Pi.

      Google announced Android Things on December of 2016. It's a modified version of the Android that we all know, but for Internet of Things (IoT) devices. The architecture of the SDK is described in the following figure:

      Android Things DP5.1 is out! and the bugs were fixed!!! You can check the release notes here!.

      You don't need to change the config.txt for the display settings and the debugger issues were solved and it is working again (tested! - it stops at the breakpoints)!

      You can download the zipped image using the Android Things Console! Check this post for more information!

      There are some problems with my two Android Things repositories and the applications are not working as expected :( but I will be updating the GitHub repositories this weekend!

      Stay tuned! and have a nice friday!

      #ProjectDIVA: Android Things DP5 (updated 24.08.2017)

      Android Things | 2 min | 1382


      Android Things DP5 is out and of course, new features are available.

      The most important features are:

      • Runtime Pin Configuration
      • OpenGL 2.0 Support (that means hardware acceleration on the RPI!)
      • ViewWeb is available!

      This time you need to use the Android Things Console to download the image as follows:

      1. Go to: Android Things Console and sign in using your Google credentials
      2. Click on: Create a new Product
      3. Go to: Factory Image
        • Select: Empty Bundle (if you don't have any app) and the Android Things v. OIR1.170720.015

      #ProjectDIVA: SensorTag Hub using a Raspberry Pi

      Android Things | 1 min | 1941

      Two posts in one day! Now the SensorTag CC2650 is running on Android Things. The Raspberry Pi 3 can be used as a sensor hub, and the SensorTag can be connected to it using BLE. I modified the original app and now it is working on Android Things! Minimal changes were required, especially on the files related with the user interface. Moreover, WebView is still not supported on Android Things.

      The code can be found here:

      Android Things | 1 min | 2759

      I've uploaded a repository for the Texas Instrument SensorTag CC2650. I updated the open source TI repository, which can be found here.

      Due to licensing restrictions (I do not know which ones) Texas Instruments was no longer able to keep the open source code in sync with the SensorTag application in Google Play. That means, the new version in Google Play has more features than this one. But this is open source, and can be modified and extended! I am planning to collect the sensor data and publish on a G...

      #ProjectDIVA: nRF24Things Rev. 0.3

      Android Things | 1 min | 770

      I've recently updated the nRF24Things project. I introduced some changes to the database main table (sensors) and to the handler class DatabaseHandler. Additionally, I added a second table for the payloads (payload). The two tables are related using the foreign key nodeID. I added some search options for the payloads: search by payloadID, nodeID etc.

      The main idea of this project is to measure the humidity, temperature, air quality etc. of a room with multiple sensors (may be using the Pi...

      #ProjectDIVA: PiCoBo Rev1.1

      Android Things | 3 min | 1573

      I had some humidity problems in the basement and I thought I can buy a dehumidifier. I bought this one on banggood Dehumidifier 500ml. I knew they are not good enough, but I wanted to try.

      This type of dehumidifier uses a peltier element to cool an alumium disipator (peltier cool side), which condenses the humidity. The condensed humidity drips into a water tank until it is full. Then, a switch is triggered and the system stops. The peltier hot side has a bigger disipator and together with a fan disipate the generated heat.

      I've just uploaded the Java codes for the rf24, rf24Network and rf24Mesh that work with Android Things. This time I didn't write a library because I thought it was better to upload an Android project that can be opened with Android Studio (>2.2.3) and directly started on the Raspberry Pi. I think this can also work with NXP Pico i.MX6UL and Intel® Edison with minor modifications (especially in the BoardDefaults file).
