今天在调试项目的时候，项目编译都正常如初，但是运行的时候直接崩掉了，异常如下：

java.lang.NoClassDefFoundError: org.greenrobot.greendao.query.WhereCollector

然后我花了一个下午时间，通过百度、QQ群、CSDN，github、stackoverflow等等，终于解决了步骤如下：

1.  添加依赖

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

1.  修改build.gradle文件

android {
        ...
        defaultConfig {
            ...
            multiDexEnabled true
           ...
        }
    ...
        }

1.  修改Application

<application
            android:name="MultiDexApplication"
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:supportsRtl="true"
            android:theme="@style/AppTheme"
            android:windowSoftInputMode="adjustPan">
         //如果有自定义的Application，就修改继承关系
         public class APPAplication extends MultiDexApplication { }

然后再次运行就解决这个异常了！
