This feature, which combines IPQS's web fingerprinting with the IPQS mobile device fingerprinting SDK , offers a flexible solution for your Android app's fraud detection needs. It can verify new or returning users and identify a wide range of high-risk behaviors, including:

• Mobile emulators
• Residential botnets
• Location spoofing
• Bots
• Non-human requests
• Fake accounts
• and hijacked devices.

With this tool, you can easily identify app install quality and gain deeper insights into your audience's KPIs. It also helps you detect duplicate accounts and prevent free trial abuse, fraudulent users, fake installs, and much more.

1. In your app's top-level build.gradle file, add the following:
   
   

   maven {
   	url = uri("https://downloads.ipqualityscore.com/maven2/")
   	credentials {
   		username "ipqs"
   		password "YOUR_API_KEY_HERE"
     	}
   	authentication {
     	  	basic(BasicAuthentication)
   	}
   }
   
   As an example, your repository list should now look similar to this:
   
   
   allprojects {
   	repositories {
   		google()
   		mavenCentral()
   		maven {
   			url = uri("https://downloads.ipqualityscore.com/maven2/")
   			credentials {
   				username "ipqs"
   				password “YOUR_API_KEY_HERE”
   			}
   			authentication { basic(BasicAuthentication) }
   		}
   	}
   }
   

2. In your app's module build.gradle file, add the dependency implementation 'com.ipqualityscore:FraudEngine:x.x.x', replacing x.x.x with the version number of the SDK (the current latest version is 1.4.0).
   
   
3. Sync your build.gradle  file. 
   
   
4. The IPQS SDK can optionally  take advantage of the following permissions if you choose to add them to your app. These permissions help us provide better results and create a better overall picture of your users. These permissions can be added to the <manifest> section of your AndroidManifest.xml file, if you choose to use them:
   
   

   <!-- Permissions -->
   <uses-permission android:name="android.permission.INTERNET"/>
   <uses-permission android:name="android.permission.READ_PHONE_STATE" />
   <uses-permission android:name="android.permission.READ_BASIC_PHONE_STATE"/>
   <!-- If allowing location request -->
   <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
   <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
   <!-- If allowing network request -->
   <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
   <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
   <!-- If allowing advertising ID -->
   <uses-permission android:name="com.google.android.gms.permission.AD_ID"/>
