VersionChecker

A small, fast, efficient and flexible open source library that checks for your app updates from REST APIs.

Documentation

Will be added as soon as possible!

Build

Building with gradle is fairly straight forward:

git clone https://github.com/mafixmafix/VersionCheckerSample.git
cd VersionCheckerSample
./gradlew build

Installation

You will need to include the version-checker-0.x.aar in your application’s runtime.

Maven

<dependency>
  <groupId>tk.pallas.versionchecker</groupId>
  <artifactId>version-checker</artifactId>
  <version>0.1.0</version>
  <type>pom</type>
</dependency>

Gradle

// Add VersionChecker dependencies
dependencies {
  implementation 'tk.pallas.versionchecker:version-checker:0.1.0'
}

Ivy

<dependency org='tk.pallas.versionchecker' name='version-checker' rev='0.1.0'></dependency>

Note: library is available ONLY on JCenter.

Usage

1. Create POJO class from JSON response.

JSON response:

{
    "data": {
        "id": 2,
        "first_name": "Janet",
        "last_name": "Weaver",
        "avatar": "https://s3.amazonaws.com/uifaces/faces/twitter/josephstein/128.jpg"
    }
}

POJO class:

public class ResultModel {
    Data data;
    public Data getData() {
        return data;
    }
    public void setData(Data data) {
        this.data = data;
    }
    @NonNull
    @Override
    public String toString() {
        return data.toString();
    }
    public static class Data {
        Integer id;
        String first_name;
        String last_name;
        String avatar;
        public Integer getId() {
            return id;
        }
        public void setId(Integer id) {
            this.id = id;
        }
        public String getFirst_name() {
            return first_name;
        }
        public void setFirst_name(String first_name) {
            this.first_name = first_name;
        }
        public String getLast_name() {
            return last_name;
        }
        public void setLast_name(String last_name) {
            this.last_name = last_name;
        }
        public String getAvatar() {
            return avatar;
        }
        public void setAvatar(String avatar) {
            this.avatar = avatar;
        }
    }
}

Note:

• reqres used for fake REST-API.
• You can use jsonschema2pojo for model JSON to POJO

2. Create VersionChecker instance in AppModule.

@Module
public abstract class AppModule {
    @Provides
    static VersionChecker provideVersionChecker(VersionCheckerClient versionCheckerClient) {
        return VersionChecker.Builder.getInstance()
                .versionCheckerClient(versionCheckerClient)
                .build();
    }
    @Provides
    static VersionCheckerClient provideVersionCheckerClient(Context context, Condition<ResultModel> condition) {
        return VersionCheckerClient
                .Builder
                .getInstance()
                .appContext(context)
                .condition(condition)
                .result(ResultModel.class)
                .url("https://reqres.in/api/users/2") // Fake REST_API :)
                .build();
    }
    @Provides
    static Condition<ResultModel> provideCondition() {
        return new Condition<ResultModel>() {
            @Override
            public void whatHappen(IVersion<ResultModel> version) {
                if (version.getNetworkInfo().isConnected() && version.getTag().equals(MainActivity.TAG)) {
                    if (version.getResult() != null) {
                        Log.d("VersionChecker", version.getResult().toString());
                        ((MainActivity) version.getActivity()).openDialogFragment();
                    }
                }
            }
        };
    }
    @Singleton
    @Binds
    abstract Context bindContext(App app);
}

Note:

• Sample is based on Dagger2 DI Framework.
• VersionChecker instance MUST be created in application scope.

3. Invoke start method in onResume method of your activity.

@Override
protected void onResume() {
    super.onResume();
    versionChecker.start(this, TAG);
}

Note:

• DON’T invoke start method in any other activity callbacks.(e.g.,onCreate)
• You can invoke start method in multiple activities!

4. Enjoy!

Note:

• See the sample for more information.

Dependencies

• Gson
• Volley

Note: All dependencies will be removed in 1.x version.

R8 / ProGuard

Will be added as soon as possible!
