So i made an app to connect to bluetooth using the bluetoothLE extensions and read files from arduino sensor to send them to thingspeak and then read them from thingspeak .
ecg_rose.aia (174.8 KB)
Here you can see app .
When i download the app directly from my android browser and install it to the phone , the app is not opening at all , giving me a message name of the app has stopped.
Any ideas why this could happen ?
