我正试图在我的项目中使用谷歌地图方向
此处引用：http://www.akexorcist.com/2015/12/google-direction-library-for-android-en.html
但是它给了我一个错误->一个.dex文件中方法引用的数量不能超过64k

最佳答案
发生此错误的原因是应用程序超过了65K方法的限制。要解决此问题，必须启用多索引支持。
按如下所示创建一个应用程序类，并在manifest.xml中的application标记下注册。
public class YouApplication extends Application {
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
更新build.gradle文件
android {
compileSdkVersion 22
buildToolsVersion "23.0.0"
defaultConfig {
minSdkVersion 14 //lower than 14 doesn't support multidex
targetSdkVersion 22
// Enabling multidex support.
multiDexEnabled true
}
}
dependencies {
compile 'com.android.support:multidex:1.0.1'
}
