android - 无法将altbeacon库包含到新项目中

Question

我正在尝试将现有的android库添加到我的新项目中。我正在使用的现有库是AltBeacon库，我能够成功编译它。

之后，我通过在新的新android项目中作为模型导入添加了AltBeacon库，并添加到了gradle中。现在，当我尝试运行新项目时，出现以下错误。

我试图探究StackOverflow上的几乎所有线程，但无法弄清楚该怎么做。



作为引用，我正在粘贴build.gradle库的AltBeacon

ext {
    isSnapshot = !project.hasProperty('release')
    isSnapCi = System.getenv('SNAP_CI') != null
    isSnapPullRequest = System.getenv('SNAP_PULL_REQUEST_NUMBER') != null
}

 */
def getVersionName = {
    def stdout = new ByteArrayOutputStream()
    try {
        exec {
            commandLine 'git', 'describe', '--tags'
            standardOutput = stdout
        }
        return stdout.toString().trim()
    }
    catch (e) {
        println("Can't get version from git: " + e);
        return "adhoc"
    }

如果您要将Android Beacon库编译为与项目链接的源代码，那么如果您具有这样的两层项目设置(假设您的项目名为“beacon”，则最简单):

beacon
  gradle.properties
  build.gradle
  app
    build.gradle

在上面的beacon文件夹内克隆Android Beacon库存储库:

git clone https://github.com/AltBeacon/android-beacon-library.git

这应该给你这样的结构:

beacon
  settings.gradle
  build.gradle
  app
    build.gradle
  android-beacon-library

更改项目的settings.gradle文件，使其看起来像这样(添加第一行):

include ':android-beacon-library'
include ':app'

编辑app / build.gradle的dependencies部分，如下所示:

dependencies {
  ...
  compile project(':android-beacon-library')
}

您可以在库reference application中看到此设置的示例，尽管注释了第2部分和第3部分以强制从JCenter加载该库。如果您想尝试使用引用，只需取消注释这些行，并注释掉这样的行:compile 'org.altbeacon:android-beacon-library:2+'
