• Added this line in the dependencies list of build.gradle (Module: app):
    compile 'com.squareup.okhttp3:okhttp:+'
Dec 27th 2017
• Embedded the code of the 'signupButt()' method in SignUp.java into an IF statement that starts with:
      if (currentLocation != null) {
So the app won't crash in case of no GPS location detection.

• Updated to Android Studio 3 and 'buildToolsVersion' to "26.0.2" in build.gradle
• Removed the following code form Manifest.xml:
    <service
        android:name=".BackgroundSoundService" 
        android:enabled="true"/>

• Moved the 'game_bkg' image from the 'drawable' folder into the 'drawable-xxhdpi' folder in order to prevent crash on Android 7 devices
Oct 6th 2017
• Added some lines of code into signupButt method in SignUp.java that save a default avatar in the User class 
• Added a custom 'pd.xml' file in the 'layout' folder and some code into Confgs.java ('showPD()'  and 'hidePD()' methods), which are used to replace the ProgressDialog code in the java files (that's because ProgressDialog is deprecated by API 26 | Android O)
So I've replaced all the:
    pd.dismiss();
    pd.setMessagge(...);
    pd.show();

with the new lines of code to show and hide the custom ProgressDialog, which start with:
   Configs.showPD(...);
   Configs.hidePD();

Gems is a Universal App Template where you have to collect as many gems as you can around your area and climb the Top Hunters leaderboard. The app gets your current location and generates a few random Gems within a customizable range in meters, so you can walk or drive to get at least 50 meters close and get them.

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 sever side.

Gems is a native Android Studio project, Java/XML language, Universal, super easy to customize, backend with Parse SDK hosted on http://back4app.com

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 by 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 persist, please contact me by my profile’s contact form and send me the Logcat message of 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:+'

We’ve recently found out that some developers have bought our app templates, reskinned them just a bit and put them on sale on other source code markets similar to CodeCanyon, saying that they developed and own such source codes.
That is a serious copyright infringement, developers who buy our templates are allowed to reskin and sell them as apps on the App Store (accordingly to the License type they’ve purchased a template for), but are not allowed to put our original source codes for sale on source code markets, including CodeCanyon. We will report developers who made copyright infringements to the competent authorities. Thanks.
