The default value uses a pool with 5 threads. 78 | 79 | You can also use `Deferred>` as the return type for the Retrofit interface functions if you'd rather deal with a `Response<>` instance instead of cathing for `HttpException`. 80 | 81 | If you want to have more control over how the `Call` gets executed, you can provide a `CoroutinesInterceptor` when creating the adapter factory. Bear in mind that, for most use cases, having an OkHttp `Interceptor` instead is a better solution. 82 | 83 | Working examples can be found in the sample project [app][5]. 84 | 85 | ## Setup 86 | 87 | Currently available via [JitPack][4]. 88 | 89 | To use it, add the jitpack maven repository to your `build.gradle` file: 90 | ```gradle 91 | repositories { 92 | ... 93 | maven { url "https://jitpack.io" } 94 | ... 95 | } 96 | ``` 97 | and add the dependency: 98 | ```gradle 99 | dependencies { 100 | ... 101 | compile 'com.github.tinsukE:retrofit-coroutines:0.5' 102 | ... 103 | } 104 | ``` 105 | 106 | ## License 107 | 108 | Copyright 2017 Angelo Suzuki 109 | 110 | Licensed under the Apache License, Version 2.0 (the "License"); 111 | you may not use this file except in
