问题描述
我有一个太大的应用程序,无法放入一个dex文件,所以我正在使用multidex。当我在某些机器上创建它时,它工作的很好,但是当我在另一个机器上创建它时,应用程序在某些设备上崩溃,而不是所有(注2上的崩溃,在Nextus 6上运行)。

我反编译APK,发现MultiDexExtractor类在classes2.dex中,而不是classes.dex。
我认为gradle v1.0.0及以上版本会自动将所有类放入正确的dex中?任何想法?
在gradle文件中,我添加了
编译'com.android.support:multidex:1.0.0'
p>
multiDexEnabled true
在默认配置中
@Override
public void onCreate(){
MultiDex.install(this);
super.onCreate();
}
我正在使用android构建工具 22.0。 1
以下是我的gradle版本:
$ ./gradlew --version

首先,mutidex最近的版本是1.0.1,所以我会建议更新你的依赖。其次,你并没有展示整个Application类,但除非你真的知道你需要现在的东西,否则我会建议扩展 android.support.multidex.MultiDexApplication
,所以你不需要需要打扰所有的init,因为MultiDexApplication会照顾到这一点。 MultiDex与我的应用程序没有问题,但是我自己扩展了 android.support.multidex.MultiDexApplication
。
I have an app that is too big to fit into one dex file so I'm using multidex. It works fine when i create it on certain machines, but when i create it on another one, the app crashes on some devices, not all (crashes on Note 2, works on Nextus 6).

I decompiled the APK, and found that the MultiDexExtractor class is in classes2.dex instead of classes.dex where it should be.
I thought gradle v1.0.0 and above is placing all the classes in the correct dex automatically? Any ideas?
In the gradle file, i've added
compile 'com.android.support:multidex:1.0.0'
in the dependencies and
multiDexEnabled true
in the default config
Then in the Application file:
@Override
public void onCreate() {
MultiDex.install(this);
super.onCreate();
}
I'm using the android build tools 22.0.1
And here are my gradle versions:
$ ./gradlew --version

First, mutidex recent version is 1.0.1, so I'd suggest updating your dependency. Second, you did not show whole Application class but unless you really know you need what you have now, I'd suggest extending android.support.multidex.MultiDexApplication
so you do not need to bother all the init as MultiDexApplication would take care of this. I had no problems with MultiDex with my apps, but I am extending android.support.multidex.MultiDexApplication
myself.
