第一:整個專案中,出現重複引用第三方包 

https://blog.csdn.net/u011930471/article/details/50389151 第二:其檔案的方法引用超過了65535個方法限制,  其解決方案為: 給專案進行分包操作,然後對其虛擬機器堆分配記憶體大小  在app的gradler配置檔案中,新增 multiDexEnabled true 開啟分包,然後新增

android {
    defaultConfig {
        applicationId "com.xunpige.nengwu"
        minSdkVersion 14
        targetSdkVersion 21

        multiDexEnabled true 
    }
}
 

android {
    dexOptions {
        javaMaxHeapSize "4g"
        preDexLibraries = false
    }
}
