No Virtual Method Com_polidea_rxandroidble_internal_radio_RxBleRadioImpl$$Lambda$1_lambda$new$0()V

I am new in Android Developement and I try to implement Bluetooth LE features on my app. I have some difficulties to run my android project with RXAndroidBLE. This library use lamb

Solution 1:

I finally found a solution by removing jackOptions. Now it works like a charm.

Solution 2:

Had this problem too. But just removing jackOptions didn't work. Had to add retrolambda to my project. My build gradle now looks like this :

apply plugin: 'com.android.application'
apply plugin: 'me.tatarka.retrolambda'

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'me.tatarka:gradle-retrolambda:3.3.1'
    }
}

repositories {
    mavenLocal()
}

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.3"
    defaultConfig {
        applicationId "com.trump.islove"
        minSdkVersion 18
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile "com.polidea.rxandroidble:rxandroidble:1.1.0"
    compile 'com.jakewharton:butterknife:8.4.0'
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'
    testCompile 'junit:junit:4.12'
}

Solution 3:

you must write to your build.gradle file:

apply plugin: 'me.tatarka.retrolambda'

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'me.tatarka:gradle-retrolambda:3.3.1'
    }
}
