我如何解决这个问题

最好的

试试这个完整的解决方案

在

onCreate（）

中执行此操作

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mLatitudeText = (TextView) findViewById(R.id.latitude);
    mLongitudeText = (TextView) findViewById(R.id.longitude);
    checkAndroidVersion();
}

此方法

checkAndroidVersion（）
这种方法
public boolean checkAndRequestPermissions() {

        int location = ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.ACCESS_FINE_LOCATION);
        List<String> listPermissionsNeeded = new ArrayList<>();

        if (location != PackageManager.PERMISSION_GRANTED) {
            listPermissionsNeeded.add(Manifest.permission.ACCESS_FINE_LOCATION);
        }
        if (!listPermissionsNeeded.isEmpty()) {
            ActivityCompat.requestPermissions(MainActivity.this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS);
            return false;
        }
        return true;
    }
public static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 1;

那就这样做吧
 @Override
    public void onStop() {
        super.onStop();
        if (mGoogleApiClient != null) {
            if (mGoogleApiClient.isConnected() && mGoogleApiClient != null) {
                mGoogleApiClient.disconnect();
            }
        }
    }

然后
/**
     * Method to verify google play services on the device
     */
    public boolean checkPlayServices() {
        int resultCode = GooglePlayServicesUtil
                .isGooglePlayServicesAvailable(this);
        if (resultCode != ConnectionResult.SUCCESS) {
            if (GooglePlayServicesUtil.isUserRecoverableError(resultCode)) {
                GooglePlayServicesUtil.getErrorDialog(resultCode, this,
                        PLAY_SERVICES_RESOLUTION_REQUEST).show();
            } else {
                Toast.makeText(MainActivity.this,
                        "This device is not supported.", Toast.LENGTH_LONG)
                        .show();
                finish();
            }
            return false;
        }
        return true;
    }

然后加上这个
@Override
    public void onConnected(@Nullable Bundle bundle) {
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        startLocationUpdates();
        mLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
        if (mLocation == null) {
            startLocationUpdates();
        }
        if (mLocation != null) {
            double latitude = mLocation.getLatitude();
            double longitude = mLocation.getLongitude();
        } else {
            // Toast.makeText(this, "Location not Detected", Toast.LENGTH_SHORT).show();
        }
        /**
         * This library works in release mode only with the same JKS key used for
         * your Previous Version
         */

    }

    protected void startLocationUpdates() {
        // Create the location request
        mLocationRequest = LocationRequest.create()
                .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
                .setInterval(5000)
                .setFastestInterval(5000);
        // Request location updates
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,

            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,
                mLocationRequest, this);
        Log.d("reque", "--->>>>");
    }

    @Override
    public void onConnectionSuspended(int i) {
        Log.i(TAG, "Connection Suspended");
        mGoogleApiClient.connect();
    }

    @Override
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
        try {
            if (checkAndRequestPermissions()) {
                buildClient();
                mGoogleApiClient.connect();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onLocationChanged(Location location) {
        current_location = location;
        SharedPrefsUtils.setStringPreference(MainActivity.this, "user_current_latitude", current_location.getLatitude() + "");
        SharedPrefsUtils.setStringPreference(MainActivity.this, "user_current_longitude", current_location.getLongitude() + "");
        System.out.println("sjkbd jdsbj");
    }

那么，为什么在重新打开应用程序后它会显示一些内容呢？您是否覆盖了onRequestPermissionResult

？覆盖了onRequestPermissionResult（），即使您不想放置任何代码，也需要覆盖它。这是应用程序正常运行所必需的。在将问题发布到此处之前，我已尝试过，但没有进行任何更改。
