Question

将房间组件添加到gradle配置文件后，

编译项目失败，错误为“找不到符号类GlideApp”。如果注释掉“注释处理器” android.arch.persistence.room:compiler:$room_version”，则项目编译不会出错。

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.otpuskarche.onleave"

Answer 1

问题出在房间上。未设置架构导出目录。由于错误出现在日志底部，因此构建日志使我感到困惑。

Answer 2

您需要添加注释处理器依赖项：

annotationProcessor 'com.github.bumptech.glide:compiler:4.0.0-RC0'

您还需要添加一个AppGlideModule。有关详细信息，请参见generated API documentation。

Answer 3

创建像这样的呼叫

@GlideModule
public final class GlideLoader extends AppGlideModule{


 }

然后构建项目。然后您将通过GlideApp访问glide。

添加Room编译器后找不到GlideApp
