Hey! is a Universal App Template where you can send short messages like hey! to all those friends who are registered in the app with just a tap. It’s that simple, the simplest communication app ever.
You can search for friends by name in the Search screen, add them to your Friends list and send them a hey!, attach a picture to it or your current location, or simple text of the selected hey!. They will receive a Push Notification and can easily reply to your “hey!” by sending it back.
Users are able to block/unblock other users, remove them from their list and make a group of friends to send heys! all at once, again, with just a tap!

Since its backend is by Parse you don’t have to buy any domain/hosting, there are NO PHP files to upload to a web server so you’ll save some money for server side.

Hey! is a native Android Studio project, Universal, super easy to customize, backend with Parse SDK hosted on https://back4app.com




About Parse SDK and back4app

Read this article for more info about back4app and Parse SDK: https://hubpages.com/technology/Parse-SDK-will-not-shutdown-in-thanks-to-back4app

Can I host Parse Server on my own server?

Yes, although I don’t provide support for the setup process, you can read the official Guide here: http://parseplatform.org

What about free support for this template?

I can offer free support for bugs encountered in the original code. Instead, if you’ve edited the code and messed something up with it, I may apply some fee to fix it either via TeamViewer or by checking your app project files directly on my computer.

How do I rename the app’s package name?

Read this tutorial to learn how to rename a package name: https://hubpages.com/technology/Android-How-to-rename-an-app-package

Should I use the latest version of Android Studio to edit this template?

Yes, I always update my apps to the latest version of the IDE and you also should make sure you’ve updated the Android Tools to their latest version of the Android SDK manager.

The demo APK crashes on startup

Make sure that the minimum Android version of your device is the one listed in the FEATURES section below. If the problem persists, please contact me through my profile’s contact form and send me the Logcat message you get when the app crashes along with the steps you made to reproduce the crash. Please note that not all real devices print an error Logcat message, in this case just run the APK into the Android Studio’s emulator and you’ll surely get the red messages about your issue.

How do I remove AdMob banner ads?

  1. Enter the .xml files where there’s an AdView and remove its code:
        <com.google.android.gms.ads.AdView
            android:id="@+id/admobBanner" 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            ads:adSize="BANNER" 
            ads:adUnitId="@string/ADMOB_BANNER_UNIT_ID" 
            android:layout_alignParentBottom="true" 
            android:layout_centerHorizontal="true">
        </com.google.android.gms.ads.AdView>
    
  2. Enter the .java files where there’s an AdRequest instance into its onCreate() method and remove its code:
            // Init AdMob banner
            AdView mAdView = (AdView) findViewById(R.id.admobBanner);
            AdRequest adRequest = new AdRequest.Builder().build();
            mAdView.loadAd(adRequest);
    
  3. Lastly, remove the play-services-ads reference in the build.gradle file:
        compile 'com.google.android.gms:play-services-ads:+'
