问题描述

我是Android开发的新手,我尝试在我的应用程序中实现Bluetooth LE功能.我在使用RXAndroidBLE运行我的android项目时遇到一些困难.该库使用lambda,我无法使其运行.

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 lambda and I am not able to make it run.

我已经更新了我的gradle文件:

I have updated my gradle file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "com.example.maxime.applicationtest"
        minSdkVersion 18
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        jackOptions {
            enabled true
        }
    }
    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-v7:25.1.0'
    testCompile 'junit:junit:4.12'
    compile "com.polidea.rxandroidble:rxandroidble:1.1.0"
}

当我尝试在MainActivity中运行以下代码时,显示错误:

When I try to run the following code in my MainActivity, an error is displayed:

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        RxBleClient rxBleClient = RxBleClient.create(this);

        Subscription scanSubscription = rxBleClient.scanBleDevices()
                .subscribe(
                        rxBleScanResult -> {
                            // Process scan result here.
                            Log.e("DEVICE", rxBleScanResult.getBleDevice().getName());
                        },
                        throwable -> {
                            // Handle an error here.
                        }
                );

// When done, just unsubscribe.
        scanSubscription.unsubscribe();
    }
FATAL EXCEPTION: Thread-4847
    Process: com.example.maxime.applicationtest, PID: 27342
        java.lang.NoSuchMethodError: No virtual method com_polidea_rxandroidble_internal_radio_RxBleRadioImpl$$Lambda$1_lambda$new$0()V in class Lcom/polidea/rxandroidble/internal/radio/RxBleRadioImpl; or its super classes (declaration of 'com.polidea.rxandroidble.internal.radio.RxBleRadioImpl' appears in /data/app/com.example.maxime.applicationtest-1/base.apk)
        at com.polidea.rxandroidble.internal.radio.RxBleRadioImpl$$Lambda$1.run(Unknown Source)
        at java.lang.Thread.run(Thread.java:818)

我不知道为什么会出错.

I've no idea why it goes wrong.

如果有人可以帮助我,那就太好了.谢谢!

If anyone could help me it would be great.Thanks!

推荐答案

您必须写入build.gradle文件:

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'
    }
}
