Update Room to remove need for Jetifying

Gander

What is this library about?

Gander is a simple in-app HTTP inspector for Android OkHttp clients. Gander intercepts and persists all HTTP requests and responses inside your application, and provides a UI for inspecting their content.

get sample apk from Google Play Store

Features

Apps using Gander will display a notification showing a summary of ongoing HTTP activity. Tapping on the notification launches the full Gander UI. Apps can optionally suppress the notification, and launch the Gander UI directly from within their own interface. HTTP interactions and their contents can be exported via a share intent.
Search HTTP Activity and also request and response
The main Gander activity is launched in its own task, allowing it to be displayed alongside the host app UI using Android 7.x multi-window support.
Gander Provides following variants
- Persistence : Saves logs to disk and TTL can be controlled
- In Memory Database : Logs will be in memory as long as the app lifecycle.
- No Op : This does nothing. So if users want Gander only in debug builds they can releaseCompile NoOp without dealing with variants, if(Build.DEBUG) ..etc

Gander requires Android 4.1+ and OkHttp 3.x.

Warning: The data generated and stored when using this interceptor may contain sensitive information such as Authorization or Cookie headers, and the contents of request and response bodies. It is intended for use during development, and not in release builds or other production deployments.

Setup

Download

Based on your IDE you can import library in one of the following ways

Gradle:

Add the dependency in your build.gradle file. Add it alongside the no-op variant to isolate Gander from release builds as follows:

// if persistence is needed (Uses Room to store the calls in DB)
debugImplementation 'com.ashokvarma.android:gander-persistence:3.1.0'

// if persistence is not needed (Data retained in memory lost on app close)
debugImplementation 'com.ashokvarma.android:gander-imdb:3.1.0'


releaseImplementation 'com.ashokvarma.android:gander-no-op:3.1.0'

If you want this in library in both release and debug builds, then try this :

// if persistence is needed (Uses Room to store the calls in DB)
implementation 'com.ashokvarma.android:gander-persistence:3.1.0'

// if persistence is not needed (Data retained in memory lost on app close)
implementation 'com.ashokvarma.android:gander-imdb:3.1.0'

or grab via Maven:

  <!--if persistence is needed (Uses Room to store the calls in DB)-->
  <dependency>
    <groupId>com.ashokvarma.android</groupId>
    <artifactId>gander-persistence</artifactId>
    <version>3.1.0</version>
    <type>pom</type>
  </dependency>
  <!--if persistence is not needed (Data lost once app is dead)-->
  <dependency>
    <groupId>com.ashokvarma.android</groupId>
    <artifactId>gander-imdb</artifactId>
    <version>3.1.0</version>
    <type>pom</type>
  </dependency>

or Download the latest Gander Persistence JAR / IMDB JAR

Usage

In your application onCreate

  @Override
    public void onCreate() {
        super.onCreate();
        // For Persistence (Uses Room to store the calls in DB)
        Gander.setGanderStorage(GanderPersistence.getInstance(this));
        // For In Memory DB (Data retained in memory lost on app close)
        Gander.setGanderStorage(GanderIMDB.getInstance());
    }

Create an instance of GanderInterceptor and add it as an interceptor when building your OkHttp client:

OkHttpClient client = new OkHttpClient.Builder()
  .addInterceptor(new GanderInterceptor(context))
  .build();

That's it! Gander will now record all HTTP interactions made by this OkHttp client.

Show Sticky/Normal Notification

Sticky => true and Normal => false

new GanderInterceptor(context).showNotification(true/false)

Other Settings

Check stored data

Launch the Gander UI directly within your app with the intent from Gander.getLaunchIntent().

startActivity(Gander.getLaunchIntent(this));

Add app shortcut to your app

Gander.addAppShortcut(this);

Redact Headers

You can redact headers that may contain sensitive information by calling redactHeader().

new GanderInterceptor(context)
    .redactHeader("Authorization")
    .redactHeader("Cookie");

Max Length

Set Response Max length to store

new GanderInterceptor(context).maxContentLength(10240L)//the maximum length (in bytes)

Retention Period

Set the retention period for HTTP transaction data captured

new GanderInterceptor(context).retainDataFor(Period.ONE_WEEK)

Chaining

You can chain all the method calls and pass it to OkHttp

new OkHttpClient.Builder()
.addInterceptor(new GanderInterceptor(context)
                     .showNotification(false)
                     .maxContentLength(250000L)
                     .retainDataFor(GanderInterceptor.Period.FOREVER)
                     .redactHeader("Authorization"))

FAQ

Why are some of my request headers missing?
Why are retries and redirects not being captured discretely?
Why are my encoded request/response bodies not appearing as plain text?

Please refer to this section of the OkHttp wiki. You can choose to use Gander as either an application or network interceptor, depending on your requirements.

Diff between Chuck and Gander:

Gander uses Room for db instead of Cupboard
Removed Gson Dependency
Improved Search
Improved Performance (PagedList, BackGround Load for Text, other minor pref boosts)
Minor fixes (Notification Channel Creation ..etc)
Many new features (Search highlight, app shortcut, Improved Notifications ..etc)
