问题描述
我目前正在使用 Android Studio 开发一个 Android 应用.目前，该应用程序在 Lollipop 设备上完美启动，但由于在预棒棒糖设备上出现 ClassNotFoundException 而在启动时崩溃(我已经在 ICS 上进行了测试，但它失败了).
I'm currently developping an Android app using Android Studio. Currently, the app is launching perfectly on Lollipop devices, but crashes at launch due to a ClassNotFoundException on pre-lollipop devices (i've tested on ICS and it fail).
缺少的类在运行时总是来自外部库.
The missing class is always from an external librairies at runtime.

我目前没有解决方案.任何有关这方面的线索将不胜感激.
I'm currently out of solution for now. Any clue about that would be appreciated.
谢谢，问候.
推荐答案
1) 为您的应用添加多索引支持:
1) Add multidex support to your app:
compile 'com.android.support:multidex:1.0.1'
2) 将您的应用程序设置为 MultiDexApplication.选择以下选项之一:
2) Set your application as a MultiDexApplication. Select one of the options below:
这是android的MultiDexApplication类的源码:
This is the source code of android's MultiDexApplication class:
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 扩展您的自定义应用程序:
Option 1) You can extend your custom application from MultiDexApplication:
public class MyApplication extends MultiDexApplication {
// Your application implementation here
}
选项 2) 您可以从默认的 Application 类扩展您的自定义应用程序，然后您需要在 调用 方法:MultiDex.installattachBaseContext(Context base)
Option 2) You can extend your custom application from default Application class, then you need to call MultiDex.install at attachBaseContext(Context base) method:
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应用程序，只需将您的应用程序名称(在 AndroidManifest.xml 中)设置为 MultiDexApplication:
Option 3) If you don't have any custom application and you don't want any, simply set your application name (at AndroidManifest.xml) to 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(参见 Option1 和 Option2)，则必须已经设置了 application 标签的 android:name到您的自定义应用程序类.
Note: If you are using a custom application class (see Option1 and Option2), application tag's android:name must already be set to your custom application class.
3) 将 multiDexEnabled true 设置添加到您的 build.gradle 文件中:
3) Add multiDexEnabled true setting to your build.gradle file:
defaultConfig {
// Other settings here
multiDexEnabled true
}
