[Android] Add Readme info for usage with RN >= 0.29.0

[c-h-]

React Native 0.29.0 modified the application template to have two files:

• MainActivity.java
• MainApplication.java

It'd be great if the docs could be updated to show usage info for it.

It appears to me that to install this package in RN >= 0.29 apps the following changes need to be made.

in MainApplication.java:

import com.aerofs.reactnativeautoupdater.ReactNativeAutoUpdaterPackage;
import javax.annotation.Nullable;


public class MainApplication extends Application implements ReactApplication {
private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
    // add this method here
    /**
     *  Name of the JS Bundle file shipped with the app.
     *  This file has to be added as an Android Asset.
     * */
    @Nullable
    @Override
    protected String getBundleAssetName() {
        return "main.android.jsbundle";
    }

    // add package to list here
    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new ReactNativeAutoUpdaterPackage(),
          new MainReactPackage()
      );
    }

And in MainActivity.java:

import com.aerofs.reactnativeautoupdater.ReactNativeAutoUpdater;
import com.aerofs.reactnativeautoupdater.ReactNativeAutoUpdater.ReactNativeAutoUpdaterUpdateType;
import com.aerofs.reactnativeautoupdater.ReactNativeAutoUpdater.ReactNativeAutoUpdaterFrequency;
import com.aerofs.reactnativeautoupdater.ReactNativeAutoUpdaterActivity;

    /**
     *  If your updates metadata JSON has a relative URL for downloading
     *  the JS bundle, set this hostname.
     * */
    @Override
    protected String getHostnameForRelativeDownloadURLs() {
        return "https://www.aerofs.com";
    }

    /**
     *  Decide what type of updates to download.
     * Available options -
     *  MAJOR - will download only if major version number changes
     *  MINOR - will download if major or minor version number changes
     *  PATCH - will download for any version change
     * default value - PATCH
     * */
    @Override
    protected ReactNativeAutoUpdaterUpdateType getAllowedUpdateType() {
        return ReactNativeAutoUpdater.ReactNativeAutoUpdaterUpdateType.MINOR;
    }

    /**
     *  Decide how frequently to check for updates.
     * Available options -
     *  EACH_TIME - each time the app starts
     *  DAILY     - maximum once per day
     *  WEEKLY    - maximum once per week
     * default value - EACH_TIME
     * */
    @Override
    protected ReactNativeAutoUpdaterFrequency getUpdateFrequency() {
        return ReactNativeAutoUpdaterFrequency.EACH_TIME;
    }

    /**
     *  To show progress during the update process.
     * */
    @Override
    protected boolean getShowProgress() {
        return false;
    }

    /**
     *  URL for the metadata of the update.
     * */
    @Override
    protected String getUpdateMetadataUrl() {
        return "https://www.aerofs.com/u/8691535/update.android.json";
    }

    /**
     * Name of the metadata file shipped with the app.
     * This metadata is used to compare the shipped JS code against the updates.
     * */
    @Override
    protected String getMetadataAssetName() {
        return "metadata.android.json";
    }

Good catch! We haven't upgraded to RN 0.29 yet. If you could make the changes to the README files, I would be happy to take a look at your pull request. Thanks!
