Getting Started

To get started with Dexter, you can add it to your project as a dependency. Here is an example of how to add Dexter to your project in your app’s build.gradle file:

dependencies {
    implementation 'com.karumi:dexter:6.2.2'
}

Once you have added Dexter to your project, you can use it to request permissions in your app.

Here is an example of how to request a permission using Dexter:

Dexter.withContext(this)
    .withPermission(Manifest.permission.READ_CONTACTS)
    .withListener(new PermissionListener() {
        @Override
        public void onPermissionGranted(PermissionGrantedResponse response) {
            // Permission granted
        }

        @Override
        public void onPermissionDenied(PermissionDeniedResponse response) {
            // Permission denied
        }

        @Override
        public void onPermissionRationaleShouldBeShown(PermissionRequest permission, PermissionToken token) {
            // Show permission rationale
        }
    }).check();

This code requests the READ_CONTACTS permission and provides a callback for handling the result of the permission request.
