Enum Constant Detail

LOCATION_PERMISSION

public static final SystemRequirementsChecker.Requirement LOCATION_PERMISSION

Invoked when:

• If running on Android M or later and your app is targeting SDK < 23 (M), any location permission (ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION) must be granted for background beacon detection.
• If running on Android M or later and your app is targeting SDK >= 23 (M), any location permission (ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION) must be granted.

Example code for asking for runtime permission:

   private void checkLocationPermissions() {
     if (SystemRequirementsHelper.shouldShowCoarseLocationRequestPermissionRationale(this)) {
       buildPermissionRationaleDialog(new DialogInterface.OnClickListener() {
          @Override public void onClick(DialogInterface dialog, int which) {
           requestPermissions(new String[] { Manifest.permission.ACCESS_COARSE_LOCATION}, REQUEST_LOCATION_PERMISSION);
         }
       }).show();
     } else {
       requestPermissions(new String[] {Manifest.permission.ACCESS_COARSE_LOCATION}, REQUEST_LOCATION_PERMISSION);
     }
   }

    @Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
     if (requestCode == REQUEST_LOCATION_PERMISSION) {
       if (grantResults.length == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
         startScanning();
       } else {
         Toast.makeText(getApplicationContext(), R.string.error_no_location_permission, Toast.LENGTH_LONG).show();
       }
     }
   }

   private AlertDialog.Builder buildPermissionRationaleDialog(DialogInterface.OnClickListener listener) {
     return new AlertDialog.Builder(this)
         .setTitle(R.string.requesting_location_permission)
         .setMessage(R.string.requesting_location_access_rationale)
         .setPositiveButton(android.R.string.ok, listener)
         .setCancelable(true);
 

LOCATION_DISABLED

public static final SystemRequirementsChecker.Requirement LOCATION_DISABLED

Invoked when Location Services are enabled and required for Bluetooth LE scanning. Their are required only on Android M or later. On Android L and below, this method will not be invoked.

You should ask user to enable it:

   // It is recommended to show dialog with explanation.
   // Dialog title: Requesting location access
   // Dialog message: Detecting beacons requires Location to be enabled.We'll never access your GPS location without your knowledge.
   // OK button: Go to settings to enable
   // Cancel button: I don't want to do this now
   Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
   activity.startActivity(intent);
 

BLUETOOTH_DISABLED

public static final SystemRequirementsChecker.Requirement BLUETOOTH_DISABLED

Invoked when Bluetooth is not enabled on the device.

You should ask user to enable it via:

   Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
   startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
 

Method Detail

values

public static SystemRequirementsChecker.Requirement[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (SystemRequirementsChecker.Requirement c : SystemRequirementsChecker.Requirement.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SystemRequirementsChecker.Requirement valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:
