Am trying to make an ionic3 pedometer application using the ionic pedometer plugin and running the finished application on my android device.
It fails to start with this error Message "No sensors found to register step counter listening to".
Please anyone with a solution please help with any other alternative plugin or way to get this working.
Hi I am late but this is the correct conclusion may be :
In some smartphones, there is simply no hardware sensor with which this plugin works, namely Sensor.TYPE_STEP_COUNTER
You can view its availability by an application like https://play.google.com/store/apps/details?id=com.cpuid.cpu_z
In the absence of this sensor, the calculation of the number of steps is through interaction with the accelerometer, by analyzing and filtering data.
so that's the reason you was see this message.
I need some help with an excruciating problem...
I have an app using DatagramSocket sending broadcast udp messages on my local network, and this work perfectly when I run it on mobiles android L (5.x) or lower.
The project has the follow permissions: internet, access_network_sate, access_wifi_state, change_wifi_state, change_wifi_multicast_satate, interact_across_users, and other permissions.
This bolded permissions was used on my app, during traffic of messages.
During the implementation TimerTasks, AsyncTasks and Threads was used to create the DatagramSocket properly, depending of the use, because I know this is necessary to send messages on network (it is necessary run network reader|writer out of main thread).
But the app not working properly when mobiles android M (6.x); anyone message is sending, and I don't have any ideia what the cause of this problem.
I'm try search about permissions on Android M, and I can see news on system permissions, but don't see anything about my specific case.
I will be very grateful if somebody can help me.
Hello everyone I've been trying to connect a GearS2 device with an Android phone using the accessory SDK, but every time the service is created and I start the connection the method "onFindPeerAgentResponse" is returning the peer as null and the result integer 1794 which is FINDPEER_SERVICE_NOT_FOUND.
I don't know if I'm doing something wrong in the config files, the manifest or the service profile.
Did you manage this? I would say to take a look at the Samsung example provided for a companion app # http://developer.samsung.com/gear check the "COMPANION TYPE : HELLO ACCESSORY" It helped me a lot.
Share some code if this example doesn't help find the problem.
Cheers,

If you mean by "lack of coverage", no connectivity, you can check this out:
