Create, update, and delete application data

Amplify Android v1 is now in Maintenance Mode until May 31st, 2024. This means that we will continue to include updates to ensure compatibility with backend services and security. No new features will be introduced in v1.

Please use the latest version (v2) of Amplify Library for Android to get started.

If you are currently using v1, follow these instructions to upgrade to v2.

Amplify libraries should be used for all new cloud connected applications. If you are currently using the AWS Mobile SDK for Android, you can access the documentation here.

Run a mutation

Now that the client is set up, you can run a GraphQL mutation with Amplify.API.mutate to create, update, and delete your data.

1Todo todo = Todo.builder()
2 .name("My todo")
3 .build();
4
5Amplify.API.mutate(ModelMutation.create(todo),
6 response -> Log.i("MyAmplifyApp", "Todo with id: " + response.getData().getId()),
7 error -> Log.e("MyAmplifyApp", "Create failed", error)
8);
1val todo = Todo.builder()
2 .name("My todo")
3 .build()
4
5Amplify.API.mutate(ModelMutation.create(todo),
6 { Log.i("MyAmplifyApp", "Todo with id: ${it.data.id}") }
7 { Log.e("MyAmplifyApp", "Create failed", it) }
8)
1val todo = Todo.builder()
2 .name("My todo")
3 .build()
4try {
5 val response = Amplify.API.mutate(ModelMutation.create(todo))
6 Log.i("MyAmplifyApp", "Todo with id: ${response.data.id}")
7} catch (error: ApiException) {
8 Log.e("MyAmplifyApp", "Create failed", error)
9}
1Todo todo = Todo.builder()
2 .name("My todo")
3 .build();
4
5RxAmplify.API.mutate(ModelMutation.create(todo))
6 .subscribe(
7 response -> Log.i("MyAmplifyApp", "Todo with id: " + response.getData().getId()),
8 error -> Log.e("MyAmplifyApp", "Create failed", error)
9 );

To update data, use ModelMutation.update(todo) instead. To delete data, use ModelMutation.delete(todo).
