Question

我目前正在使用Android Studio开发Android应用。目前，该应用程序在Lollipop设备上完美启动，但由于在棒棒糖前设备上ClassNotFoundException（我在ICS上进行了测试并且失败了），因此在发布时崩溃。

缺少的类总是来自运行时的外部库。

这里是gradle文件：

    buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.0'
    defaultConfig {
        applicationId 'com.kappsports.kapp10'
        minSdkVersion 18
        targetSdkVersion 23
        versionCode 1
        versionName '1.0.0'
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            shrinkResources true
        }
    }
    lintOptions {
        abortOnError false
    }
    dexOptions {
        incremental true
        javaMaxHeapSize '4g'
    }
}

repositories {
    mavenCentral()
    maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
    maven { url 'https://maven.fabric.io/public' }
    jcenter()
}

dependencies {
    compile fileTree(dir: 'libs', exclude: 'android-support-v4.jar', include: '*.jar')
    compile('com.crashlytics.sdk.android:crashlytics:2.5.1@aar') {
        transitive = true;
    }
    compile 'com.michaelpardo:activeandroid:3.1.0-SNAPSHOT'
    compile 'com.github.johnpersano:supertoasts:1.3.4@aar'
    compile 'com.google.code.gson:gson:2.3'
    compile 'com.squareup:otto:1.3.5'
    compile 'com.makeramen:roundedimageview:1.3.0'
    compile 'com.jakewharton:butterknife:6.0.0'
    compile 'com.malinskiy:superrecyclerview:1.0.0'
    compile 'com.android.support:multidex:1.0.1'
    compile 'com.jpardogo.materialtabstrip:library:1.0.9'
    compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.3'
    compile 'com.squareup.okhttp:okhttp:2.4.0'
    compile 'org.buraktamturk:loadingview:1.0.0@aar'
    compile 'com.facebook.android:facebook-android-sdk:4.1.0'
    compile 'com.github.navasmdc:MaterialDesign:1.5@aar'
    compile 'net.danlew:android.joda:2.8.2'
    //noinspection GradleCompatible
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile 'com.google.android.gms:play-services:7.5.0'
    //noinspection GradleCompatible
    compile 'com.android.support:recyclerview-v7:22.2.1'

}

这是一段logcat输出：

我目前暂时没有解决方案。关于这一点的任何线索将不胜感激。

谢谢，问候。

Answer 1

1）为您的应用添加multidex支持：

compile 'com.android.support:multidex:1.0.1'

2）将您的应用设置为MultiDexApplication。选择以下选项之一：

这是android＆＃39; s MultiDexApplication类的源代码：

public class MultiDexApplication extends Application {
    public MultiDexApplication() {
    }

    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }
}

选项1）您可以从MultiDexApplication扩展自定义应用程序：

public class MyApplication extends MultiDexApplication {
    // Your application implementation here
}

选项2）您可以从默认Application课程扩展自定义应用程序，然后您需要以MultiDex.install方法致电attachBaseContext(Context base)：

public class MyApplication extends Application {

    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }

    // Your application implementation here
}

选项3）如果您没有任何自定义应用程序并且您不想要任何自定义应用程序，只需将您的应用程序名称（在AndroidManifest.xml中）设置为MultiDexApplication：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android.multidex.myapplication">
    <application
        ...
        android:name="android.support.multidex.MultiDexApplication">
        ...
    </application>
</manifest>

注意：如果您使用的是自定义应用程序类（请参阅选项1和选项2），则必须已将application标记android:name设置为自定义应用程序类。

3）将multiDexEnabled true设置添加到build.gradle文件中：

defaultConfig {
    // Other settings here
    multiDexEnabled true
}

More information.

Answer 2

我忘了在自定义应用程序类的onCreate（）方法中的超级调用之后添加此行：

 MultiDex.install(getBaseContext());

感谢Kane的解决方案！

Answer 3

在某些低端设备上添加MultiDex.install(getBaseContext());到MyApplication onCreate()无效？导致java.lang.NoClassDefFoundError：

将MultiDex.install(getBaseContext());添加到MyApplication attachBaseContext(Context base)

的工作是什么

public class MyApplication extends Application {
...
   @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(base);
    }
...

Answer 4

您可以在清单文件的应用程序标记中添加它。

android:name="android.support.multidex.MultiDexApplication"

Android：app在Lollipop上运行时加载库，但不是IceCreamSandwich
