android - Android Studio无法使用外部库启动应用程序

Question

我想在我的android应用程序中使用ftp工具，因此我尝试添加apache-commons-net:3.4库。
构建成功完成，但是在我要运行或调试应用程序时失败。
因此，我尝试使用ivy-2-4-0库和Chilkat库，因为所有这些库我都遇到相同的错误。
除了Chilkat有所不同之外，我仅将库复制到了libs目录中，并在项目结构的file选项卡中声明了dependencies依赖项。

显示的错误是:

Executing tasks: [:app:assembleDebug]

Configuration on demand is an incubating feature.

com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536","sources":[{}]}

您有太多方法。 dex 只能有 65536方法。

您可以使用multidex support。

只需将这些行添加到build.gradle中:

android {

    defaultConfig {
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.0'
}

同样在您的Manifest中，将multidex支持库中的MultiDexApplication类添加到application元素中

<?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>

如果您使用自己的Application类，请将父类从Application更改为MultiDexApplication。
