Question

我正在尝试编译我正在处理的react本机模块。我认为问题在于/android/src/main/java...而不是/android/TeamCode/src/main/java /android/TeamCode/src。如果是这种情况，我将如何制作它以便在/android/src而不是- module --- index.js --- package.json --- android //this is where the below screenshot is from ----- build.gradle ----- TeamCode ------- build.gradle //apply from: '../build.common.gradle' --- Example //this is the app I am trying to compile ----- index.android.js ----- android ----- package-lock.json ----- other stuff中反映原生的内容？但是我不知道这是不是问题，我可能完全错了。

以下是我的项目：

当我添加wherePivot()时，我仍然收到第一个错误。

Answer 1

我不知道React Native，但在Android中，要做到这一点，你必须更改build.gradle。找到android部分，然后添加sourceSets部分，如下所示：

android {
    //...
    sourceSets {
        main {
            // Like this...
            java.srcDirs += 'TeamCode/src/main/java'
            // ...or maybe, like that...
            java.srcDirs += 'android/TeamCode/src/main/java'
            // Dirty, extreme alternative...
            java.srcDirs += '/Users/zoe/saas/robotics/ftcnative/android/TeamCode/src/main/java'
        }
    }
}

请注意，这是添加其他源目录（因为+=）。

Answer 2

更改一个Java方法之一的名称后，我遇到了同样的问题。

我通过以下方式解决了该问题：

删除我的android build文件夹，然后再次运行react-native run-android。
