我到了java.lang.NullPointerException.我在app level gradle中更改了build.gradle.我的build .gradle如下:

apply plugin: 'com.android.application'
apply from: "../../../buildCommon/applicationCommon.gradle"
apply from: "../../../buildCommon/common.gradle"

android {
    compileSdkVersion 19
    buildToolsVersion "25.0.2"

    defaultConfig {
        applicationId "era.safetynet.payment.apps"
        minSdkVersion 14
        targetSdkVersion 17
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile project.modules."acra"
    compile ":neurotec-biometrics-client-android"
    compile ":neurotec-devices-fscanners-nitgen-android"
    compile ":neurotec-devices-fscanners-suprema-biomini-android"
    compile ":neurotec-devices-fscanners-bluefin-android"
    compile ":neurotec-devices-multimodal-credenceid-android"
    compile ":neurotec-devices-fscanners-digitalpersona-uareu-android"
    compile ":neurotec-devices-fscanners-secugen-android"
    compile ":neurotec-devices-fscanners-futronic-android"

    compile ":neurotec-devices-irisscanners-iritech-irishield-android"
    compile ":neurotec-devices-media-android"
    compile project(':ftrSDKHelperAndroid')
    compile 'com.android.support:support-v4:19.1.0'
    compile project(":samples-utils") …

当我尝试在探戈教程中启动项目时,会出现这样的错误.我应该在哪里解决这个问题？
