我已经在我的gradle中启用了multiDexEnabled true。需要一些帮助来解决这个问题。谢谢。

Answer 1

在依赖项标记下添加以下链接：

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

同步并运行......

Answer 2

在build.gradle文件中

    dependencies {

       ...
        //Multi Dex
        compile 'com.android.support:multidex:1.0.1'
       ....
    }

在示例应用程序类

中

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

然后清洁＆amp;建立项目

Answer 3

compile＆＃39; com.android.support：multidex：1.0.1＆＃39;

为我工作...... 我试图从mac运行应用程序（在Windows上构建）。它在应用程序启动时崩溃。

谢谢大家..
