Learn how to setup your first Android project powered by Appwrite and the Appwrite Android SDK using Java.

Using Kotlin?

Check out the Start with Android (Kotlin) guide.

1. Create Android project

Open Android Studio and click New Project to create a new project.

Choose your desired project template, for example Empty Activity, and click Next.

Now enter your app name and package name. You will need both of these later when you create your project in the Appwrite console. Click Finish to create your project.

2. Create Appwrite project

Head to the Appwrite Console.

If this is your first time using Appwrite, create an account and create your first project.

Then, under Add a platform, add an Android app.

Add your app's name and package name, your package name is the one entered when creating an Android project. For existing projects, you should use the applicationId in your app-level build.gradle file.

You can skip optional steps.

3. Add the Appwrite SDK

To add the Appwrite SDK for Android as a dependency, add the following to your app-level build.gradle file inside the dependencies block.

Groovy

implementation "io.appwrite:sdk-for-android:8.1.0"

In order to allow creating OAuth sessions, the following activity needs to be added inside the <application> tag, along side the existing <activity> tags in your AndroidManifest.xml. Be sure to replace the <PROJECT_ID> string with your actual Appwrite project ID. You can find your Appwrite project ID in you project settings screen in your Appwrite Console.

Markup

<manifest ...>
  ...
  <application ...>
    ...
    <!-- Add this inside the `<application>` tag, along side the existing `<activity>` tags -->
    <activity android:name="io.appwrite.views.CallbackActivity" android:exported="true">
      <intent-filter android:label="android_web_auth">
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="appwrite-callback-<PROJECT_ID>" />
      </intent-filter>
    </activity>
  </application>
</manifest>

4. Create Appwrite helper class

Find your project's ID in the Settings page.

Create a new file AppwriteHelper.java and add the following code to it, replacing <PROJECT_ID> with your project ID.

Java

package <YOUR_ROOT_PACKAGE_HERE>;

import android.content.Context;

import java.util.Map;

import io.appwrite.Client;
import io.appwrite.ID;
import io.appwrite.coroutines.CoroutineCallback;
import io.appwrite.models.Session;
import io.appwrite.models.User;
import io.appwrite.services.Account;

public class AppwriteHelper {
    private static AppwriteHelper instance;
    private Client client;
    private Account account;

    private AppwriteHelper(Context context) {
        client = new Client(context)
                .setEndpoint("https://<REGION>.cloud.appwrite.io/v1")
                .setProject("<PROJECT_ID>");

        account = new Account(client);
    }

    public static synchronized AppwriteHelper getInstance(Context context) {
        if (instance == null) {
            instance = new AppwriteHelper(context.getApplicationContext());
        }
        return instance;
    }

    public interface AuthCallback<T> {
        void onSuccess(T result);
        void onError(Exception error);
    }

    public void login(String email, String password, final AuthCallback<Session> callback) {
        account.createEmailPasswordSession(
            email,
            password,
            new CoroutineCallback<>((result, error) -> {
                if (error != null) {
                    callback.onError(error);
                    return;
                }
                callback.onSuccess(result);
            })
        );
    }

    public void register(String email, String password, final AuthCallback<User<Map<String, Object>>> callback) {
        account.create(
            ID.unique(),
            email,
            password,
            new CoroutineCallback<>((result, error) -> {
                if (error != null) {
                    callback.onError(error);
                    return;
                }
                callback.onSuccess(result);
            })
        );
    }

    public void logout(final AuthCallback<Object> callback) {
        account.deleteSession(
            "current",
            new CoroutineCallback<>((result, error) -> {
                if (error != null) {
                    callback.onError(error);
                    return;
                }
                callback.onSuccess(result);
            })
        );
    }
}

5. Create a login UI in XML

First, update your activity_main.xml layout file:

Markup

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="16dp"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/textViewStatus"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:padding="16dp"
        android:textSize="18sp"
        android:visibility="gone" />

    <Button
        android:id="@+id/buttonLogout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Logout"
        android:layout_marginBottom="16dp"
        android:visibility="gone" />

    <EditText
        android:id="@+id/editTextEmail"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="8dp"
        android:hint="Email"
        android:inputType="textEmailAddress" />

    <EditText
        android:id="@+id/editTextPassword"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="16dp"
        android:hint="Password"
        android:inputType="textPassword" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <Button
            android:id="@+id/buttonLogin"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:layout_marginEnd="8dp"
            android:text="Login" />

        <Button
            android:id="@+id/buttonRegister"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:layout_marginStart="8dp"
            android:text="Register" />
    </LinearLayout>

</LinearLayout>

6. Create MainActivity

Now update your MainActivity.java file with the following code:

Java

package <YOUR_ROOT_PACKAGE_HERE>;

import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

import androidx.appcompat.app.AppCompatActivity;

import java.util.Map;

import io.appwrite.models.Session;
import io.appwrite.models.User;

public class MainActivity extends AppCompatActivity {
    private static final String TAG = "MainActivity";

    private EditText editTextEmail;
    private EditText editTextPassword;
    private Button buttonLogin;
    private Button buttonRegister;
    private TextView textViewStatus;
    private Button buttonLogout;
    private AppwriteHelper appwrite;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Initialize Appwrite
        appwrite = AppwriteHelper.getInstance(getApplicationContext());

        setContentView(R.layout.activity_main);

        // Initialize UI components
        editTextEmail = findViewById(R.id.editTextEmail);
        editTextPassword = findViewById(R.id.editTextPassword);
        buttonLogin = findViewById(R.id.buttonLogin);
        buttonRegister = findViewById(R.id.buttonRegister);
        textViewStatus = findViewById(R.id.textViewStatus);
        buttonLogout = findViewById(R.id.buttonLogout);

        // Set up click listeners
        buttonLogin.setOnClickListener(v -> login());
        buttonRegister.setOnClickListener(v -> register());
        buttonLogout.setOnClickListener(v -> logout());
    }

    private void login() {
        String email = editTextEmail.getText().toString().trim();
        String password = editTextPassword.getText().toString().trim();

        if (email.isEmpty() || password.isEmpty()) {
            Toast.makeText(this, "Please enter email and password", Toast.LENGTH_SHORT).show();
            return;
        }

        appwrite.login(email, password, new AppwriteHelper.AuthCallback<Session>() {
            @Override
            public void onSuccess(Session result) {
                runOnUiThread(() -> {
                    Toast.makeText(MainActivity.this, "Login successful", Toast.LENGTH_SHORT).show();
                    showLoggedInUI(email);
                });
            }

            @Override
            public void onError(Exception error) {
                runOnUiThread(() -> {
                    Log.e(TAG, "Login failed", error);
                    Toast.makeText(MainActivity.this, "Login failed: " + error.getMessage(), Toast.LENGTH_SHORT).show();
                });
            }
        });
    }

    private void register() {
        String email = editTextEmail.getText().toString().trim();
        String password = editTextPassword.getText().toString().trim();

        if (email.isEmpty() || password.isEmpty()) {
            Toast.makeText(this, "Please enter email and password", Toast.LENGTH_SHORT).show();
            return;
        }

        appwrite.register(email, password, new AppwriteHelper.AuthCallback<User<Map<String, Object>>>() {
            @Override
            public void onSuccess(User<Map<String, Object>> result) {
                runOnUiThread(() -> {
                    Toast.makeText(MainActivity.this, "Registration successful. You can now login.", Toast.LENGTH_SHORT).show();
                });
            }

            @Override
            public void onError(Exception error) {
                runOnUiThread(() -> {
                    Log.e(TAG, "Registration failed", error);
                    Toast.makeText(MainActivity.this, "Registration failed: " + error.getMessage(), Toast.LENGTH_SHORT).show();
                });
            }
        });
    }

    private void logout() {
        appwrite.logout(new AppwriteHelper.AuthCallback<Object>() {
            @Override
            public void onSuccess(Object result) {
                runOnUiThread(() -> {
                    Toast.makeText(MainActivity.this, "Logout successful", Toast.LENGTH_SHORT).show();
                    showLoginUI();
                });
            }

            @Override
            public void onError(Exception error) {
                runOnUiThread(() -> {
                    Log.e(TAG, "Logout failed", error);
                    Toast.makeText(MainActivity.this, "Logout failed: " + error.getMessage(), Toast.LENGTH_SHORT).show();
                });
            }
        });
    }

    private void showLoggedInUI(String email) {
        editTextEmail.setVisibility(View.GONE);
        editTextPassword.setVisibility(View.GONE);
        buttonLogin.setVisibility(View.GONE);
        buttonRegister.setVisibility(View.GONE);

        textViewStatus.setVisibility(View.VISIBLE);
        buttonLogout.setVisibility(View.VISIBLE);

        textViewStatus.setText("Logged in as " + email);
    }

    private void showLoginUI() {
        editTextEmail.setVisibility(View.VISIBLE);
        editTextPassword.setVisibility(View.VISIBLE);
        buttonLogin.setVisibility(View.VISIBLE);
        buttonRegister.setVisibility(View.VISIBLE);

        textViewStatus.setVisibility(View.GONE);
        buttonLogout.setVisibility(View.GONE);
    }
}
