Question

我有一个使用Dagger 2的项目，我无法在Android 4+上运行该应用程序，它崩溃了。但是在Android 5+上它运行得很好。所以这就是我得到的错误：

08-05 05:03:38.076  25444-25444/app.xqute.com.xqute E/AndroidRuntime﹕ FATAL EXCEPTION: main

这是build.gradle文件，其中包含我使用的设置：

 apply plugin: 'com.android.application'
 apply plugin: 'me.tatarka.retrolambda'
 apply plugin: 'com.neenbedankt.android-apt'






 android {
compileSdkVersion 22
buildToolsVersion "22.0.1"

defaultConfig {
    applicationId "app.xqute.com.xqute"
    multiDexEnabled = true
    minSdkVersion 15
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

 signingConfigs {
    release {
        storeFile file("xQute.jks")
        storePassword "saswat123"
        keyAlias "xQute"
        keyPassword "saswat123"
    }

 }

buildTypes {
    release {
        minifyEnabled false
        shrinkResources true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.release
    }
}
compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
lintOptions {
      abortOnError false
  }



 }


 dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
apt "com.google.dagger:dagger-compiler:2.0"

 }

compile.exclude module: 'support-annotations'
 }

为什么它适用于Android 5+但不适用于Android 4+的任何想法？

Answer 1

对于低于21的android API级别，您需要在构建gradle文件中添加以下依赖项，并且需要将Application类更改为MultiDexApplication，如下所示：

在应用程序build.gradle文件中：

Implementation 'com.android.support:multidex:1.0.3'

在BaseApplication中，将Application类更改为MultiDexApplication：

public class BaseApplication extends MultiDexApplication {
    @Override
    public void onCreate() {
        super.onCreate();
    }
}

java.lang.NoClassDefFound使用Dagger 2 for Android 4
