Unless you change the versionCode so that it does not rely on Git, you need to keep the Android-nRF-Blinky in its Git repository. to do so, simply clone it via Git instead of downloading a zip.

To do so, first ensure you have git installed on your computer. Then, navigate to the folder where you want to have the repository and type this in your terminal:

git clone https://github.com/NordicSemiconductor/Android-nRF-Blinky.git

I am sorry, I am not familiar with "repository". I go to this web site...https://github.com/NordicSemiconductor/Android-nRF-Blinky to get the zipped file for the software. Please explain what you mean by getting it from a repository?

Thanks again.

It may not be incorrect, but it is not intentional, and if you do, it will fail like you have described. If you check out the git repository instead, it will work. Alternatively you could modify build.gradle to not rely on Git for version information.

Thanks for responding. What I did was go to Github and downloaded the ZIP file for the blinky app. Was that incorrect?

Hi,

Did you resolve this? I am no Android developer, but looking at the code I wonder if you download the files instead of checking out the git repo? I expect that would cause problems as versionCode is set to getVersionCodeFromTags() in build.gradle, and that only works within a Git repo.

Okay so, I read that the UART app is not being supported any longer, so I tried The Nordic Toolbox. It runs and loads into the phone but when I try to connect the app just shuts down. I read that it would be simpler to start with the blinky app as it's simpler. When I try to build that I get this error...

Cause: android.defaultConfig.versionCode is set to -1, but it should be a positive integer

How do i fix that?

import android.support.v4.content.LocalBroadcastManager;

LocalBroadcastManager doesnt't exist

I tried running an example project and the UART project and I can't get it to build using the latest Android Studio. Is there a version I should run this on? I am new to Android Studio.

Thanks,

Yes, Android Studio (projects are using Gradle).

Einar,

Thanks, I will look at the examples. What platform do I run them on? Android Studio?

Hi Jerry,

I recommend you look at the Android BLE Library, including the examples. You can also look at the nRF-Toolbox implementation.
