所以我想知道为什么在尝试在比lollipop更早的Android版本上运行我的应用程序时遇到64k dex方法限制,当它在更新的版本上运行时很好。
可能是,因为在旧版本上运行时实际上正在引用支持库吗?
这是我的傻瓜:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion '23.0.2'
lintOptions {
checkReleaseBuilds true
// Or, if you prefer, you can continue to check for errors in release builds,
// but continue the build even when errors are found:
abortOnError false
}

回答您的具体问题是:
这就是为什么它在旧设备上失败但它适用于较新设备的原因。它与支持库无关。
为我的答案添加更多有用的内容:
但也许有些人可能想知道的是如何在旧设备上解决它,请注意我在上面的要点上使用了natively
这个词。这意味着,有一些解决方法可以让旧平台支持它,但您必须将这些变通方法编码到您的应用中。
此Google指南详细说明了解决方法(甚至问题本身):http://developer.android.com/tools/building/multidex.html
它的基础是:
compile 'com.android.support:multidex:+'
multiDexEnabled true
MultidexApplication
android:name="android.support.multidex.MultiDexApplication"
扩展,或者,如果您需要为自己的应用程序子类Application
,请使您的应用程序从中扩展。答案 1 :(得分:2)
完全同意@Budius。您必须在清单中提及应用程序类。并让您的应用程序类扩展MultiDexApplication。
还需要做一件事。在MultiDexApplication类中调用附加基本上下文
public class MyApplicationClass extends MultiDexApplication... {
....
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(MyApplicationClass.this);
}
...
}
这对我在棒棒糖前后设备上运行良好。

使用Instant Run和pre-lollipop设备时出现问题!

您应该将multiDexEnabled = true
添加到您的defaultConfig
gradle文件中。
