我用过
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
minSdkVersion 14
targetSdkVersion 23
...
multiDexEnabled true
}
dependencies {
compile 'com.android.support:multidex:1.0.1'
...
}
在app
级build.gradle
和
<manifest package="com.example"
...
<application
android:name=".AppContext"
...
>
>
由于我的应用程序肯定引用了超过64K的方法,因此在manifest
中很长时间了。现在,我将其更改为 Android Studio 3.3.2
下的新SDK和multidex
lib
compileSdkVersion 27
buildToolsVersion "27.0.3"
defaultConfig {
minSdkVersion 14
targetSdkVersion 27
...
multiDexEnabled true
}
dependencies {
compile 'com.android.support:multidex:1.0.3'
...
}
在所有可用的Android 4.X设备上安装时,和应用已开始崩溃。大多数崩溃都具有如下的堆栈跟踪:

我发现解决问题的唯一方法是排除
// compile 'com.android.support:multidex:1.0.3'
从app
级build.gradle
开始并更改
public class AppContext extends Application {
...}
到
public class AppContext extends MultiDexApplication {
...}
这是build tools 27.x.x
中的错误还是什么!?

您可以尝试这种方式,
1)删除
multiDexEnabled是
来自应用程序gradle 并仅添加
实现'com.android.support:multidex:1.0.3'

我的一个应用程序中存在相同的问题。使用应用扩展MultiDexApplication
,如下所示:
public class AppContext extends MultiDexApplication {
...
}
并使用如下所示的multidex依赖项:
compile 'com.android.support:multidex:1.0.3'
没有用。
我通过在Application类中使用MultiDex.install
来解决此问题。像这样:
import android.support.multidex.MultiDex;
public class AppContext extends Application {
...
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
