ScanCallback does not call on Android 10
Stalker11 opened this issue · 9 comments
Hello everyone.
I try to scan BLE devices on Android 10, but ScanCallback does not call. All permissions are granted.
On previous versions Android it works fine.
Used library version no.nordicsemi.android.support.v18:scanner:1.1.0 and no.nordicsemi.android:ble:1.2.0
After migration to no.nordicsemi.android.support.v18:scanner:1.4.3 and no.nordicsemi.android:ble:2.2.4 I still have this problem.
Could you help me, how I can solve it?
You need to enable Location Service as well. You may find it in the quick settings under name Location. When disabled, no app have a access to any location-related features, which includes scanning for BLE devices as well.
Location Service is enabled and all permissions granted. But ScanCallback does not find any devices only on Android 10.
Then I have no idea. Try restarting Bluetooth, the phone or checking another phone with Android 10.
Do you request ACCESS_FINE_LOCATION, not ACCESS_COARSE_LOACTION?

I have tested on different devices (Huawei, Samsung, Xiaomi). None of them does works with BLE.
Permissions:
android.permission.ACCESS_BACKGROUND_LOCATION
android.permission.ACCESS_COARSE_LOCATION
android.permission.ACCESS_FINE_LOCATION
android.permission.BLUETOOTH
android.permission.BLUETOOTH_ADMIN
yes
I have no idea what was wrong, but I have changed requiring runtime permissions in the migration app and it works:
private val locationPermission = if (Build.VERSION.SDK_INT >= 29) permission.ACCESS_FINE_LOCATION else permission.ACCESS_COARSE_LOCATION
Hey @Stalker11 did you find any solution?
