海外TECH	DEV Community	Simple Google Map App - Jetpack Compose	https://dev.to/vtsen/simple-google-map-app-jetpack-compose-2ebb	Simple Google Map App Jetpack ComposeStep by step guides to implement Google Map app using Jetpack Compose components for the Android Maps SDKThis article was originally published at vtsen hashnode dev on Aug This simple Google Map app is based on the simplified version of sample app from this Google Map compose library In addition I added the following features into this sample app Location Permission Request Device Location Setting Request Setup Google Cloud ProjectThe first thing you need to do is setting up a Google cloud project to generate an API key which allows you to use the Google Maps SDK API Setup New Project in console cloud google comIn your project dashboard go to APIs overviewIn API amp Services page go to LibrarySearch for Maps SDK for Android and enable itBack to the API amp Services page go to CredentialsSelect CREATE CREDENTIALS then select API keyThe API key is now generated Click on the API Key to edit it You can rename the API key name to whatever you like For this sample app purpose you do not need to set any restrictions on this API key Select None for Application restrictionsSelect Don t restrict key for API restrictionsThese are just brief instructions For detailed official instructions see below Set Up in the Google Cloud ConsoleUsing API keysPlease note I haven t setup any billing account or enable billing and it still works Once you have the API key it is time to implement the code Add dependencies in build gradleThese are the libraries needed to use Google Map compose library implementation com google maps android maps compose implementation com google android gms play services maps implementation androidx compose foundation foundation beta Setup Secrets Gradle PluginSecrets Gradle Plugin is basically a library to help you hide your API key without committing it to the version control system It allows you to define your variable e g API key in the local properties file which is not checked into version control and retrieve the variable For example you can retrieve the variable in the AndroidManifest xml file These are the steps to add the Secrets Gradle plugin In project level build gradle buildscript dependencies classpath com google android libraries mapsplatform secrets gradle plugin secrets gradle plugin In app level build gradle plugins id com google android libraries mapsplatform secrets gradle plugin Add MAPS API KEY in local propertiesIn local properties file copy the API key you get from Setup Google Cloud Project steps above and paste it here MAPS API KEY Your API Key here Add meta data in AndroidManifest xmlIn order to read the MAPS API KEY variable that you defined in local properties you need to add the lt meta data gt in the AndroidManifext xml Add this lt meta data gt tag within the lt application gt tag lt application lt meta data android name com google android geo API KEY android value MAPS API KEY gt lt application gt If you do not setup Secrets Gradle plugin above you will get this error Attribute meta data com google android geo API KEY value at AndroidManifest xml requires a placeholder substitution but no value for lt MAPS API KEY gt is provided Add Internet and Location PermissionsSince the app needs to access internet and location permissions we add these permissions in the AndroidManifest xml lt manifest xmlns android gt lt uses permission android name android permission INTERNET gt lt uses permission android name android permission ACCESS FINE LOCATION gt lt uses permission android name android permission ACCESS COARSE LOCATION gt lt manifest gt Implement GoogleMap and Marker GoogleMap and Marker are the composable functions from the library that we can call to show the map and the markers on the map The map shows the current position if available and it is defaulted to Sydney Composable private fun MyGoogleMap currentLocation Location cameraPositionState CameraPositionState onGpsIconClick gt Unit val mapUiSettings by remember mutableStateOf MapUiSettings zoomControlsEnabled false GoogleMap modifier Modifier fillMaxSize cameraPositionState cameraPositionState uiSettings mapUiSettings Marker state MarkerState position LocationUtils getPosition currentLocation title Current Position GpsIconButton onIconClick onGpsIconClick DebugOverlay cameraPositionState By default the zoom control is on To turn it off you create a new MapUiSettings and pass that into the GoogleMap as parameter The map also have GPS icon When you click on it it moves the camera to the current location It also requests location permission and to enable device location setting if those requests have not been granted before DebugOverlay just an overlay screen to show the current camera status and position Request Location PermissionTo check whether the location permission has already been granted you use ContextCompat checkSelfPermission API fun isLocationPermissionGranted context Context Boolean return ContextCompat checkSelfPermission context Manifest permission ACCESS FINE LOCATION PackageManager PERMISSION GRANTED If the location permission is not granted you setup the callback whether the permission is granted or denied using rememberLauncherForActivityResult with ActivityResultContracts RequestPermission To request the location permission using you call the ActivityResultLauncher launch Composable fun LocationPermissionsDialog onPermissionGranted gt Unit onPermissionDenied gt Unit val requestLocationPermissionLauncher rememberLauncherForActivityResult ActivityResultContracts RequestPermission isGranted Boolean gt if isGranted onPermissionGranted else onPermissionDenied SideEffect requestLocationPermissionLauncher launch Manifest permission ACCESS FINE LOCATION Note Inititally I used the permissions library from accompanist It worked only if the permission is granted It did not work well when the permission denied and I want to request the permission again So I decided to use rememberLauncherForActivityResult instead Enable Location SettingWhen the location permission has already granted you want to make sure the location setting is turned on If it is off you want to request the user to turn it on Similar to request location permission above you use rememberLauncherForActivityResult to register enable location setting request callback val enableLocationSettingLauncher rememberLauncherForActivityResult contract ActivityResultContracts StartIntentSenderForResult activityResult gt if activityResult resultCode Activity RESULT OK onSuccess else onFailure To check whether the location setting is turned on you call SettingsClient checkLocationSettings API which returns the Task lt LocationSettingsResponse gt which allows you to set up the failure and success callbacks If the callback is failed it means the device location setting is off In that case you want to request user to enable it if it is resolvable exception is ResolvableApiException To do that you call ActivityResultLauncher launch API with the resolution PendingIntent that you get from the exception val locationRequest LocationRequest create apply priority Priority PRIORITY HIGH ACCURACY val locationRequestBuilder LocationSettingsRequest Builder addLocationRequest locationRequest val locationSettingsResponseTask LocationServices getSettingsClient context checkLocationSettings locationRequestBuilder build locationSettingsResponseTask addOnSuccessListener onSuccess locationSettingsResponseTask addOnFailureListener exception gt if exception is ResolvableApiException try val intentSenderRequest IntentSenderRequest Builder exception resolution build enableLocationSettingLauncher launch intentSenderRequest catch sendEx IntentSender SendIntentException sendEx printStackTrace else onFailure Refer to LocationSettingDialog in the source code Get the last known locationFinally you want to get the last known location which is also a current location if the device location setting is turned on First you set up the LocationCallback to receive the LocationResult which has the last known location information The callback is then removed to save power To request the location update you call FusedLocationProviderClient requestLocationUpdates API by passing in the LocationRequest LocationCallback and Looper SuppressLint MissingPermission fun requestLocationResultCallback fusedLocationProviderClient FusedLocationProviderClient locationResultCallback LocationResult gt Unit val locationCallback object LocationCallback override fun onLocationResult locationResult LocationResult super onLocationResult locationResult locationResultCallback locationResult fusedLocationProviderClient removeLocationUpdates this val locationRequest LocationRequest create apply interval fastestInterval priority Priority PRIORITY HIGH ACCURACY Looper myLooper let looper gt fusedLocationProviderClient requestLocationUpdates locationRequest locationCallback looper ConclusionThe app requests the location permission and request to enable location setting during start up It requests again when the user click in the GPS icon if requests haven t been granted It also moves the camera back to current position when the GPS icon is clicked For details and if you want to play around with the app refer to the following source code Source CodeGitHub Repository Demo
