java.lang.IllegalStateException: Fragment MapFragment{2fe7116} (69b05d78-5cf3-46a9-829c-6b6507944575) not attached to an activity.?


I am developing location based android app using google maps but when I run project I am getting crash and getting following exception java.lang.IllegalStateException: Fragment MapFragment{2fe7116} (69b05d78-5cf3-46a9-829c-6b6507944575) not attached to an activity. at androidx.fragment.app.Fragment.requireActivity(Fragment.java:995)

I am getting exception in following function in my MapFragment

@SuppressLint("MissingPermission")
private fun getDeviceLocation() {
    /*
     * Get the best and most recent location of the device, which may be null in rare
     * cases when a location is not available.

    try {
        if (locationPermissionGranted) {
            val locationResult = fusedLocationProviderClient.lastLocation
            locationResult.addOnCompleteListener(requireActivity()) { task ->
                if (task.isSuccessful) {
                    // Set the map's camera position to the current location of the device.
                    lastKnownLocation = task.result
                    if (lastKnownLocation != null) {

Solution

  • Remove requireActivity(), it gives this IllegalStateException. See Explanation from official document.

    locationResult.addOnCompleteListener {task ->
        if (task.isSuccessful) {
            // Your Code
        }
    }
    

    Get Location, according to official documentation.
