MPAndroidChart PieChart

Question

在我的项目中，使用库MaterialDesign。当我添加库MPchart时，我收到此错误并且不明白什么是错的。谢谢

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build.gradle项目：

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')
}. 

如果我删除依赖，我会得到其他错误。我能做什么？

看来你在com.nineoldandroids:library:2.4.+和你的项目中声明了依赖MPChartLib。这就是导致问题的原因。

尝试从项目中删除依赖项，但将其保留在MPChartLib中，以便dextool只看到一次。您的新build.gradle将如下所示：

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')

}

对Android支持库也是如此。它应该只声明一次，否则你会得到类似的错误。
