A PhotoGallery implementation that includes Facebook Messenger and Parse integration.

Directions for Sharing Images with Facebook Messenger

This is a step-by-step guide of adding a share-to-Facebook-Messenger functionality into PhotoGallery.

Step 1)

Go to to the Facebook Developer portal and create a new Android project.

Step 2) Add App Id to Strings.xml

<string name="facebook_app_id">XXXXXXXXXXXXXXX</string>

Step 3) Add App Id to AndroidManifest.xml

...

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">

    <meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/facebook_app_id"/>

        ...

Step 4) Add Facebook SDK Dependency

compile 'com.facebook.android:facebook-android-sdk:4.0.0'

Step 5) Add New Permission to AndroidManifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Step 6) Add Share Functionality

Drawable mDrawable = mImageView.getDrawable();
Bitmap mBitmap = ((BitmapDrawable) mDrawable).getBitmap();
String path = MediaStore.Images.Media.insertImage(getActivity().getContentResolver(), mBitmap, "Image Description", null);
Uri uri = Uri.parse(path);

ShareToMessengerParams shareToMessengerParams = ShareToMessengerParams.newBuilder(
                uri,
                "image/*"
).build();

MessengerUtils.shareToMessenger(getActivity(), REQUEST_CODE_SHARE_TO_MESSENGER, shareToMessengerParams);

Directions for Saving Recent Searches with Parse

Go to the Parse Application Portal, signup, and then add a new app.

Step 1) Add Parse Dependency

The top-level build.gradle file should have a section like this:

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://jitpack.io"
        }
    }
}

While the app build.gradle should include these depencencies:

compile 'com.github.yongjhih:parse:1.9.2'
compile 'com.parse.bolts:bolts-android:1.2.0'

Step 2) Create Search Model Object

This class will represent a single search query that we want to save.

@ParseClassName("Search")
public class Search extends ParseObject {

    public String getText() {
        return getString("text");
    }

    public void setText(String text) {
        put("text", text);
    }

    public ParseUser getAuthor() {
        return getParseUser("author");
    }

    public void setAuthor(ParseUser currentUser) {
        put("author", currentUser);
    }

    public void setUuidString() {
        UUID uuid = UUID.randomUUID();
        put("uuid", uuid.toString());
    }

    public String getUuidString() {
        return getString("uuid");
    }

    public static ParseQuery<Search> getQuery() {
        return ParseQuery.getQuery(Search.class);
    }

}

Step 3) Setup Parse in Application

public class PhotoGalleryApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        ParseObject.registerSubclass(Search.class);
        Parse.enableLocalDatastore(this);
        Parse.initialize(this, "YOUR_APP_ID", "YOUR_CLIENT_KEY");
        ParseUser.enableAutomaticUser();
        ParseACL defaultACL = new ParseACL();
        ParseACL.setDefaultACL(defaultACL, true);
    }

}

Step 4) Use Parse

Here are some basic operations to start with:

Save a Single Search

Search search = new Search();
search.setUuidString();
search.setText(query);
search.setAuthor(ParseUser.getCurrentUser());
search.pinInBackground("ALL_SEARCHES");

Load All Searches

ParseQuery<Search> query = Search.getQuery();
query.fromLocalDatastore();
query.findInBackground((list, e) -> {
    // Do something with list
});

Delete All Searches

ParseObject.unpinAllInBackground("ALL_SEARCHES");
