没有找到类＆QUOT; android.support.multidex.MultiDexApplication＆QUOT;在路径：DexPathList [英] Didn't find class "android.support.multidex.MultiDexApplication" on path: DexPathList
问题描述
我想新的 MultiDex支持我的应用到目前为止我已经成功地正确编译我的应用程序，但在运行时，我得到了以下异常：
I'm trying the new MultiDex Support on my app and so far I've managed to compile my app correctly, but when running it, I get the following exception:
java.lang.RuntimeException: Unable to instantiate application android.support.multidex.MultiDexApplication: java.lang.ClassNotFoundException: Didn't find class "android.support.multidex.MultiDexApplication" on path: DexPathList[[zip file "/data/app/me.myapp.main-2.apk"],nativeLibraryDirectories=[/data/app-lib/me..main-2, /vendor/lib, /system/lib]]

这是我的摇篮文件：
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.0"
defaultConfig {
minSdkVersion 16
targetSdkVersion 21
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
debug {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
packagingOptions {
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/NOTICE.txt'
}
}
repositories {
mavenCentral()
mavenLocal()
}
dependencies {
compile 'com.android.support:multidex:1.0.0'
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:support-v4:21.0.0'
compile 'com.android.support:support-v13:21.0.0'
compile 'com.android.support:appcompat-v7:21.0.0'
}
和我的AndroidManifest.xml：
And my AndroidManifest.xml:
<application
android:name="android.support.multidex.MultiDexApplication">
我不明白是什么问题。我想我根据文档做的一切。有没有别的东西我失踪？我确信我已经从SDK管理器安装了最新的支持库和回购。
I don't understand what the problem is. I think I'm doing everything according to the documentation. Is there something else i am missing? I made sure I had the latest support library and repo installed from the SDK manager.
推荐答案
我的配置：
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.14.+' // 0.14.1, 2014-11-6
}
}
dependencies {
compile 'com.android.support:multidex:1.0.0'
}
android {
compileSdkVersion = 21
buildToolsVersion = "21.1.0"
defaultConfig {
minSdkVersion 14
targetSdkVersion 21
multiDexEnabled true
}
}
不幸的是，我有同样的问题。但是我发现一个奇怪的现象：
Unfortunately, I have the same problem. But I found a strange situation:
编译/中间体/ DEX /调试：
build/intermediates/dex/debug:
-rw-rw-r-- 1 andrew andrew 2221176 Nov 6 20:18 classes2.dex
-rw-rw-r-- 1 andrew andrew 8357596 Nov 6 20:18 classes.dex
解压缩APK，建立/输出/ APK：
unzip apk, build/outputs/apk:
-rw-rw-r-- 1 andrew andrew 8357596 Nov 6 20:18 classes2.dex
-rw-rw-r-- 1 andrew andrew 2221176 Nov 6 20:18 classes.dex
在APK，classes.dex的主要类别应大于classes2.dex，但它不是。我也dex2jar和放大器;解压缩罐检查类，应用程序类是不存在的classes.dex，其classes2.dex反之。
In apk, the main classes of classes.dex should be bigger than classes2.dex, but its not. I do also dex2jar & unzip jar to check classes, the application class is not there in classes.dex, its in classes2.dex contrarily.
不过，我应该有固定它。这是我的修补安卓摇篮插件，您可以试试：
However, I should have fixed it. Here is my patched android gradle plugin you can try:
buildscript {
repositories {
mavenCentral()
maven { url 'https://github.com/yongjhih/android-gradle-plugin.m2/raw/master/' }
}
dependencies {
classpath 'com.infstory.tools.build:gradle:0.14.+'
}
}
该补丁是：<一href="https://github.com/yongjhih/android-gradle-plugin/commit/9c2212e3b1b4c6e1f7b47f2086aba1903a6258bf" rel="nofollow">https://github.com/yongjhih/android-gradle-plugin/commit/9c2212e3b1b4c6e1f7b47f2086aba1903a6258bf 要么 https://android-review.googlesource.com/#/c/113331/
问题： https：//开头code。 google.com/p/android/issues/detail?id=78761
官方补丁 https://android-review.googlesource.com/# / C / 113201 / 已经被合并，我想这可能是固定的下一个版本。
The official patch is https://android-review.googlesource.com/#/c/113201/ that already been merged, I think it might be fixed in next version.
