TinyWeb

TinyWeb is a simple http server library for Android.

For settings.gradle

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}

For settings.gradle.kts

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven("https://jitpack.io")
    }
}

Install gradle dependencies

dependencies {
    implementation 'com.github.tejmagar:tinyweb:v1.0.1-alpha'
}

Creating a View

Create public class for each route. Note: if the class is not public, the server may not behave as expected.

import androidx.annotation.NonNull;

import org.tinyweb.request.Request;
import org.tinyweb.response.HttpResponse;
import org.tinyweb.response.Response;
import org.tinyweb.views.View;

public class HomeView extends View {
    @NonNull
    @Override
    public Response response(Request request) {
        return new HttpResponse("Hello World");
    }
}

Creating a server instance

    // Other imports...

    import org.tinyweb.Server;
    import org.tinyweb.TinyWebLogging;
    import org.tinyweb.paths.Path;

    public class MainActivity extends AppCompatActivity {
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            // To see logs
            // TinyWebLogging.enableLogging = true;
            Server server = new Server(8080);
            server.addRoute(new Path("/", HomeView.class));
            server.run();
        }
    }

Handling form upload

TinyWeb currently supports only multipart/form-data. Other encoding types will be added soon.

import androidx.annotation.NonNull;

import org.tinyweb.forms.Files;
import org.tinyweb.parsers.MultipartParser;
import org.tinyweb.request.Request;
import org.tinyweb.response.HttpResponse;
import org.tinyweb.response.Response;
import org.tinyweb.stream.Stream;
import org.tinyweb.views.View;

import java.io.IOException;

public class HomeView extends View {
    @NonNull
    @Override
    public Response response(Request request) {
        if (request.method.equals("POST")) {
            MultipartParser multipartParser = new MultipartParser(request.headers, request.stream);
            try {
                MultipartParser.ParseResult parseResult = multipartParser.parse();
                Files.TempFile tempFile = parseResult.files.value("file");

                return new HttpResponse(parseResult.formData.toString() +
                        "\n" + "filename: " + tempFile.fileName + " path: " + tempFile.file.getAbsolutePath());
            } catch (MultipartParser.MultipartParseException | Stream.StreamReadException |
                     IOException e) {
                return new HttpResponse(e.getMessage());
            }
        }
        return new HttpResponse("Hello World");
    }
}

Tips

Running server in foreground service helps to serve pages in background even after closing app.
