Runtime permissions are essential in Android applications to ensure that users have control over their data and privacy. Below are examples of how runtime permissions can be used in production apps. These examples showcase best practices for requesting permissions and handling users' responses.
// Example of requesting location permission in an Android app
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
// Permission is not granted
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
LOCATION_PERMISSION_REQUEST_CODE);
} else {
// Permission has already been granted
accessLocation();
}
// Handling the permission request response
@Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case LOCATION_PERMISSION_REQUEST_CODE: {
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, do the location-related task
accessLocation();
} else {
// permission denied, show a message to the user
Toast.makeText(this, "Location permission is required to access location.", Toast.LENGTH_SHORT).show();
}
return;
}
}
}
