今天新建了一个项目,Gradle中增加了一些类库,比如OkGo、LitePal等

下载完成后真机运行报错

点击错误详细信息如下:

  • Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

解决方法:

打开项目的gradle.properties文件,新增两句

android.useAndroidX=true
android.enableJetifier=true

问题解决.
