SETUP:https://parse.com/apps/quickstart#parse_data/mobile/android/native/existing 

.5 Create a test app in Parse dashboard to get AppID and ClientKey (found in: App Settings -> Security and keys)
1. Download the latest Parse.jar, and copy and paste to your app/lib/Parse.jar.
then add:
 dependencies {

compile fileTree(dir: 'libs', include: 'Parse-*.jar')

}
to /GradleScripts/build.graddle(app)

2. Now create a new directory ParseApp, here we are going to setup the parse app, Create class ParseSetup ( we will add this class to your Manifest).

public class ParseSetup extends Application {

    @Override    public void onCreate() {
        super.onCreate();
        Parse.enableLocalDatastore(this);
        Parse.initialize(this);        //setupParse();        ParseObject testObject = new ParseObject("TestObject");        testObject.put("foo", "bar222");        testObject.saveInBackground();

    }

}

3. Open AndroidManifest.xml and add the name of the Parse App class here (ParseSetup). ex:

<application    android:name=".ParseApp.ParseSetup"    android:allowBackup="true"    android:icon="@mipmap/ic_gamma"    android:label="@string/app_name"    android:supportsRtl="true"    android:theme="@style/AppTheme">    <activity android:name=".MainActivity">        <intent-filter>            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />        </intent-filter>    </activity>
    <meta-data        android:name="com.parse.APPLICATION_ID"        android:value="your_ID" />    <meta-data        android:name="com.parse.CLIENT_KEY"        android:value="your_key" />

also add the below Permissions:

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

Android Tutorial: Share with Facebook, and with other apps.

Android: Share with Facebook

Facebook doesn't work well with normal sharing intents when sharing multiple content elements as discussed in this bug. To share posts with facebook, we need to:

1. Create a new Facebook app here (follow the instructions)
2. Add the Facebook SDK to your Android project:

SetUp:

a. App/build.gradle (add below)

repositories { mavenCentral() }

dependencies {
     

    compile 'com.facebook.android:facebook-android-sdk:4.7.0'   
}

b. Add you Facebook app id to strings.xml

<string name="facebook_app_id">1698838388383</string>

c. Add Facebook activity to AndroidManifest.xml, also add <meta-data AppID />

Activity:

<!-- Share to Facebook -->

<activity android:name="com.facebook.FacebookActivity"></activity>

Meta-data:

<meta-data    

android:name="com.facebook.sdk.ApplicationId"    

android:value="@string/facebook_app_id" />

b. Add you Facebook Library to your AndroidStudio project.
1. Download SDK from here: Facebook SDK
2. unzip
3. On Android Studio go to: 

•  File -> New -> New Module
• Select "Import .JAR/.AAR package"
• Go to your unzip Facebook SDK, and select facebook-android-sdk-4.7.0.aar

• Click next. Done :)

Share from Menu bar:

ShareFB.java , menu_shareFB.xml

a. edit menu_shareFB.xml:

<menu xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item        android:id="@+id/action_share"        android:icon="@android:drawable/ic_menu_share"        android:title="Some title"        app:showAsAction="always"        >
        <menu>            <item                android:id="@+id/action_share_Facebook"                android:title="Share with Facebook"/>            <item                android:id="@+id/action_share_other_Apps"                android:title="Share with other Apps"/>
        </menu>
    </item></menu>

b. Now edit ShareFB.java:

@Overridepublic boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_campaign_detail, menu);    return true;}
@Overridepublic boolean onOptionsItemSelected(MenuItem item) {
    switch(item.getItemId()) {

        case R.id.action_share_Facebook:
        {
            setupFacebookShareIntent();            Toast.makeText(getApplicationContext(), "here facebok", Toast.LENGTH_LONG).show();        }
        break;      //  case  R.id.action_share:        case R.id.action_share_other_Apps:
        {
            setupShareIntent();            Toast.makeText(getApplicationContext(), "here 2", Toast.LENGTH_LONG).show();        }
        break;    }
    return super.onOptionsItemSelected(item);}

//Share with Facebookpublic void setupFacebookShareIntent() {
    ShareDialog shareDialog;    FacebookSdk.sdkInitialize(getApplicationContext());    shareDialog = new ShareDialog(this);
    ShareLinkContent linkContent = new ShareLinkContent.Builder()
            .setContentTitle("SumOfUs")
            .setContentDescription(
                    "\"Title Of Test Post\"")
            .setContentUrl(Uri.parse("http://www.sumofus.org"))
            .build();
    shareDialog.show(linkContent);
    //MessageDialog.show(this, linkContent);}



// Gets the image URI and setup the associated share intent to hook into the provider
public void setupShareIntent() {
    // Fetch Bitmap Uri locally    ImageView ivImage = (ImageView)findViewById(R.id.ivCampaign);    // Get access to the URI for the bitmap    Uri bmpUri = getLocalBitmapUri(ivImage);    if (bmpUri != null) {
        // Construct a ShareIntent with link to image        Intent shareIntent = new Intent();        shareIntent.setAction(Intent.ACTION_SEND);        shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);        shareIntent.putExtra(Intent.EXTRA_SUBJECT, "Title Of Test Post");        shareIntent.putExtra(Intent.EXTRA_TEXT, "https://www.sumofus.org");        shareIntent.setType("image/*");        // Launch sharing dialog for image        startActivity(Intent.createChooser(shareIntent, "send"));    } else {
        Toast.makeText(this, "Some error occured during sharing", Toast.LENGTH_LONG).show();
    }

}

// Returns the URI path to the Bitmap displayed in specified ImageView
public Uri getLocalBitmapUri(ImageView imageView) {
    // Extract Bitmap from ImageView drawable    Drawable drawable = imageView.getDrawable();    Bitmap bmp = null;    if (drawable instanceof BitmapDrawable){
        bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();    } else {
        return null;    }

    // Store image to default external storage directory    Uri bmpUri = null;    try {
        File file =  new File(Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_DOWNLOADS), "share_image_" + System.currentTimeMillis() + ".png");        file.getParentFile().mkdirs();        FileOutputStream out = new FileOutputStream(file);        bmp.compress(Bitmap.CompressFormat.PNG, 90, out);        out.close();        bmpUri = Uri.fromFile(file);    } catch (IOException e) {
        e.printStackTrace();    }
    return bmpUri;
}

TODO:
add github repo here:

Reference:

1. 
   Share using this code snippet:

 public void setupFacebookShareIntent() {
      ShareDialog shareDialog;
      FacebookSdk.sdkInitialize(getApplicationContext());
      shareDialog = new ShareDialog(this);

      ShareLinkContent linkContent = new ShareLinkContent.Builder()
              .setContentTitle("Title")
              .setContentDescription(
                      "\"Body Of Test Post\"")
              .setContentUrl(Uri.parse("http://someurl.com/here"))
              .build();
      
      shareDialog.show(linkContent);
  }
