Mantra (MFS 100) Biometric Android Example.
Creating a New Project
First, we will create a new Android Studio Project.1) Adding Jar File In Android Project.
- Now download the https://download.mantratecapp.com/Forms/UserDownload . Android SDK File And Get mantra.mfs100.jar..
- So first on the project explorer select Project.
- Then inside app/lib paste the mantra.mfs100.jar that we downloaded.
- Then add dependency in your build.gradle.
implementation files('libs/mantra.mfs100.jar')
- Adding jniLibs Folder
· jniLibs.jar
· Download jinLibs.jar file And then Extract.
· Put jniLibs folder src/main/
- build.gradle In Your Project
apply plugin: 'com.android.application' android { compileSdkVersion 30 defaultConfig { applicationId "com.mantra.mfs100testv9032" minSdkVersion 15 targetSdkVersion 30 versionCode 1 versionName "1.0" multiDexEnabled true } dexOptions { preDexLibraries false javaMaxHeapSize "4g" } buildTypes { release { minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } repositories { flatDir { dirs 'libs' } } } dependencies { implementation fileTree(include: ['*.jar'], dir: 'libs') implementation 'androidx.appcompat:appcompat:1.0.0' implementation 'androidx.constraintlayout:constraintlayout:1.1.3' }
