Setup

1. Ensure that your Minimum SDK version is at least API level 24 or above. In case your android project compiles for API level below 24, you can include the following line in your AndroidManifest.xml file to avoid any compilation issues : <uses-sdk tools:overrideLibrary="com.truecaller.android.sdk"/> Using this would ensure that the SDK works normally for API level 24 & above, and would be disabled for API level < 24. Note: Please make sure that you put the necessary API level checks before accessing the SDK methods in case of compiling for API level < 24

2. 2.1) Add the Truecaller SDK which contains OAuth functionality to your app-level build.gradle file dependencies {

   ...

   implementation "com.truecaller.android.sdk:truecaller-sdk:3.0.0"

   } 2.2) Also, add the following lines of code in your gradle file, if not already present android{

   compileOptions{

   sourceCompatibility JavaVersion.VERSION_1_8

   targetCompatibility JavaVersion.VERSION_1_8

   }

   }

3. Add mavenCentral() in your project level build.gradle file :

   allprojects{

   repositories{

   ...

   mavenCentral()

   ...

   } Also check your AGP and distribution URL version AGP : 7.4.2 (minimum) distributionUrl=https\://services.gradle.org/distributions/gradle-7.5-bin.zip (minimum).

4. Configure Client ID :

a.) Open your strings.xml file. Example path: /app/src/main/res/values/strings.xml and add a new string with the name "clientID" and value as your "clientID"

b.) Open your AndroidManifest.xml and add a meta-data element to the application element

<application android:label="@string/app_name" ...>

...

<meta-data android:name="com.truecaller.android.sdk.ClientId" android:value="@string/clientID"/>

...
