Android SDK 21 - crash when starting BlueTooh LE scan

[davidbilik]

When you want to start ranging for beacons, this error occurs:

java.lang.IllegalArgumentException: This cannot be run on UI thread, starting BLE scan can be expensive at com.estimote.sdk.internal.Preconditions.checkArgument(Preconditions.java:65) at com.estimote.sdk.service.BeaconService.checkNotOnUiThread(BeaconService.java:529) at com.estimote.sdk.service.BeaconService.access$600(BeaconService.java:62) at com.estimote.sdk.service.BeaconService$InternalLeScanCallback.onLeScan(BeaconService.java:517) at android.bluetooth.BluetoothAdapter$2.onScanResult(BluetoothAdapter.java:1703) at android.bluetooth.le.BluetoothLeScanner$BleScanCallbackWrapper$1.run(BluetoothLeScanner.java:330) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:135) at android.app.ActivityThread.main(ActivityThread.java:5221) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:899) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:694)

I dont know how to workaround now since this happens in your SDK.

What OS/device?

[davidbilik]

Well, OS Android 5.0 Lollipop, newest preview and device Nexus 5.

[wiktor]

Oh, oh. I need to double check newest preview release.

Hi Wiktor, I have the same problem. If you have a solution please let me know. Thanks!

[wiktor]

0.4.3 version fixes this issue. Can you verify?

[lthlth91]

I'm not sure whether it's hardware problem or Android L's problem, the updated Estimote Official app can barely detect all the beacons synchronously.

[wiktor]

Agat so you mean by synchronously?

I got the same thing "This cannot be run on UI thread, starting BLE scan can be expensive"

This is on the new lollipop nexus 5 (21)

BUT the latest release fixed it !!! thanks for this

[lthlth91]

please download the updated sdk. The exception should be fixed, and also let me know how the new OS works with your beacon app. Thanks!

Still App is not working app is crashing in Nexus5(lollipop OS).Giving the above exception.I tried with the latest estitmote sdk jar i.e., 0.4.3 version still getting the same issue.

[wiktor]

Which L version? What device?

Can you install Estimote app from Play Store and check if it works for you?
