我有一个使用Dagger 2的项目,我无法在
Android 4上运行应用程序,它崩溃了.但是在Android 5上它运行得很好.所以这是我得到的错误：

任何想法为什么它适用于Android 5但不适用于Android 4？
解决方法
对于低于21的android API级别,您需要在构建gradle文件中添加以下依赖项,并且需要将Application类更改为MultiDexApplication,如下所示：
在app build.gradle文件中：
Implementation 'com.android.support:multidex:1.0.3'
在您的BaseApplication中将Application类更改为MultiDexApplication：
public class BaseApplication extends MultiDexApplication {
@Override
public void onCreate() {
super.onCreate();
}
}
