Question

我正在使用GoogleAPI客户端和locationRequest类来实现这一点，但没有显示对话，在logcat中它显示错误“缺少R.string.google_key”，我需要帮助如何实现这个以及需要哪个谷歌密钥此

public class MainActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {


    protected static final int REQUEST_CHECK_SETTINGS = 0x1;
    GoogleApiClient googleApiClient;

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        if (googleApiClient == null) {
            googleApiClient = new GoogleApiClient.Builder(this)
                    .addApi(LocationServices.API)
                    .addConnectionCallbacks(this)
                    .addOnConnectionFailedListener(this).build();
            googleApiClient.connect();

            LocationRequest locationRequest = LocationRequest.create();
            locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
            locationRequest.setInterval(30 * 1000);
            locationRequest.setFastestInterval(5 * 1000);
            LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
                    .addLocationRequest(locationRequest);

            //**************************
            builder.setAlwaysShow(true); //this is the key ingredient
            //**************************

Try below code its perfectly working for me


private static int REQUEST_CODE_RECOVER_PLAY_SERVICES = 200;
private GoogleApiClient mGoogleApiClient;
private LocationRequest mLocationRequest;  
private AppLocationService appLocationService;
@Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);

        setContentView(R.layout.reserve_user_screen);
appLocationService = new AppLocationService(ReserveUser.this);
showLocationAlertDialog(ReserveUser.this);
}

protected synchronized void buildGoogleApiClient() {
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API).build();

    }
