java - MPAndroidChart 饼图

Question

在我的项目中，使用库 MaterialDesign .当我还添加库 MPchart 时，出现此错误并且不明白出了什么问题。谢谢你

UNEXPECTED TOP-LEVEL EXCEPTION:

MaterialDesign库的build.gradle:

dependencies {
  compile 'com.nineoldandroids:library:2.4.+'
  compile 'com.android.support:support-v4:21.0.3'
}

和项目的build.gradle:

dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
  compile 'com.android.support:support-v4:21.0.3'
  compile 'com.android.support:appcompat-v7:21.0.3'
  compile 'com.android.support:recyclerview-v7:21.0.0'
  compile 'com.nineoldandroids:library:2.4.+'
  compile project(":MaterialDesign")
  compile project(":MPChartLib")
  compile files('libs/opencsv-2.4.jar')
}. 

如果删除依赖项，则会出现其他错误。我能做什么？

Answer 1

您似乎在 MPChartLib 和您的项目中都声明了依赖项 com.nineoldandroids:library:2.4.+。这就是导致问题的原因。

尝试从您的项目中删除依赖项，但将其保留在 MPChartLib 中，以便 dextool 只看到它一次。你的新 build.gradle 看起来像这样:

dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
  compile 'com.android.support:appcompat-v7:21.0.3'
  compile 'com.android.support:recyclerview-v7:21.0.0'
  compile project(":MaterialDesign")
  compile project(":MPChartLib")
  compile files('libs/opencsv-2.4.jar')

也对 Android 支持库执行相同的操作。它应该只声明一次，否则你会得到类似的错误。
