ScreenshotsNanny

Introduction

Until the time of writing, the Android toolchain doesn't have anything to help take screenshots automatically for publishing on Google Play Store.

The other fact is that most of the modern apps consume internet resources, or have UGC (user-generated content). And for the screenshots showing on Google Play, no one would like to see any arbitrary content which may be ugly or even inappropriate.

Be professional! Be beautiful! You can achieve it easily by using ScreenshotsNanny.

Comparison

Below are two different screenshots for the same activity. The left one is using real arbitrary content, while the right one is using prepared mock response.

Setup & Sample code

There are two approaches to utilizing this library.

  • Setup an automated UI test (e.g. Espresso).
  • Create another product flavor in your project to do the screenshot job.

I'll explain the product flavor approach in detail. You can also check out the demo module along with this project.

1 - Add a product flavor (let's name it " screenshots") to your target module's build.gradle:

productFlavors {

  prod {

applicationId "PRODUCT_DEFAULT_APP_ID"
  
}

  screenshots {

applicationId "PACKAGE_NAME.screenshots"
  
}
 
}

2 - Create a blank dummy activity in the screenshots flavor: MODULE/src/screenshots/java/PACKAGE_NAME/ScreenshotsPrimeActivity.java

You can leave the layout as it is (an empty view group), because we don't really need it.

3 - Set the created activity as the launcher activity in that product flavor:

MODULE/src/screenshots/AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
  <application>

<activity android:name="PACKAGE_NAME.ScreenshotsPrimeActivity"

 android:label="@string/title_activity_screenshots_prime">

 <intent-filter>

  <action android:name="android.intent.action.MAIN" />

  <category android:name="android.intent.category.LAUNCHER" />

  <category android:name="android.intent.category.DEFAULT" />

 </intent-filter>

</activity>
  </application> </manifest>

4 - Add the core screenshot code to the new launcher activity ScreenshotsPrimeActivity.java.

There are two major methods: startActivityAndTakeScreenshot & startActivityContainsMapAndTakeScreenshot. Without passing screenshotDelay, the former one uses default value 3 seconds, and the latter one takes screenshot immediately when map view is ready. You could give your own screenshotDelay to both of the methods.

public class ScreenshotsPrimeActivity extends AppCompatActivity {

private MockServerWrapper mServer;

@Override
  protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_screenshots_prime);

 // Set up the screenshot fixture

 // Set language (resources configuration) other than the default one if it's necessary

// LanguageSwitcher.change(this, "de");


 // Set up the mock server

mServer = new MockServerWrapper();

// Read mock response(s) from resource directory

String response = ResourceReader.readFromRawResource(ScreenshotsPrimeActivity.this, R.raw.github_user);

ParameterizedCallback changeUrlCallback = new ParameterizedCallback() {

 @Override

 public void execute(String value) {

  // The MockServer runs on arbitrary port each time

  // We have to change production's base URL to the MockServer URL via reflection

  PowerChanger.changeFinalString(GithubService.class, "API_URL", value);

 
}

}
;

// Start mock server with canned response(s), it accepts response(s) as varargs

mServer.start(changeUrlCallback, response);

  
}

@Override
  protected void onResume() {

super.onResume();

 // Start desired activities one by one, and take screenshot accordingly

 startActivityAndTakeScreenshot(MainActivity.class, new Callback() {

 @Override

 public void execute() {

  // Start a normal activity

  startActivity(new Intent(ScreenshotsPrimeActivity.this, MainActivity.class));

 
}

}
);

 startActivityAndTakeScreenshot(SecondActivity.class, new Callback() {

 @Override

 public void execute() {

  // Start an activity by an intent which contains something

  startActivity(SecondActivity.createIntent(ScreenshotsPrimeActivity.this, "London bridge is falling down"));

 
}

}
);

 startActivityAndTakeScreenshot(NetworkActivity.class, new Callback() {

 @Override

 public void execute() {

  // This activity will consume mock response and present it

  startActivity(new Intent(ScreenshotsPrimeActivity.this, NetworkActivity.class));

 
}

}
);

 startActivityAndTakeScreenshot(AccountActivity.class, new Callback() {

 @Override

 public void execute() {

  // Prepare persistent data before starting the activity

  AccountManager.create(getApplicationContext(), "Bruce Lee");

  AccountManager.update(getApplicationContext(), 1048576);

  startActivity(new Intent(ScreenshotsPrimeActivity.this, AccountActivity.class));

 
}

}
);

 startActivityContainsMapAndTakeScreenshot(MapsActivity.class, new Callback() {

 @Override

 public void execute() {

  // Take screenshot for an activity which contains Map, need to pass map view id

  startActivity(new Intent(ScreenshotsPrimeActivity.this, MapsActivity.class));

 
}

}
, R.id.map);

 if (!ActivityCounter.isAnyActivityRunning) {

 Log.i(Constants.LOG_TAG, "? Done.");

 // Stop mock server when all screenshot jobs are done

 mServer.stop();

 finish();

}

  
}
 
}

5 - Select screenshotsDebug as build variant, run it. Then all screenshots will be placed under DEVICE_STORAGE/Screenshots/APP_NAME/. Each screenshot file is named as corresponding activity name (format is PNG).

Screenshots

  • The Android Status Bar won't be captured as part of the screenshot, so you don't have to worry about the messy icons there.
  • Forget about the annoying on-screen keyboard, this library will hide it for you.
  • MapView (no matter if it fulfills the window or not) will also be taken into the screenshot.
  • For any activity consumes network resources, you can replace the content by canned mock responses. (This library is using MockWebServer from Square, Inc.)
  • Some activities may read values from persistent data (e.g. SharedPreferences), you can also prepare the values before activity starts.

(sorry, these demo activities layouts were made with poor design, look ugly)

AppAuth for Android is a client SDK for communicating with OAuth 2.0 and OpenID Connect providers. It strives to directly map the requests and responses of those specifications, while following the idiomatic style of the implementation language. In addition to mapping the raw protocol flows, convenience methods are available to assist with common tasks like performing an action with fresh tokens.

Following the same approach that RxActivityResult does, RxPermissionsResult is a reactive wrapper around the permission's Android Api, which allows to get the data without breaking the observable chain.

You don't want your apps look and feel boring, do you? Add some bubbles!
