我正在创建一个应该有两种口味的应用程序,无板篮球和足球.当我根据https://developer.android.com/tools/building/configuring-gradle.html设置我的项目时,只有其中一种口味得到认可,即netball和其他风味的包装,即足球不是.

这是我的build.gradle文件

apply plugin: 'com.android.application'

 android {
compileSdkVersion 22
buildToolsVersion "22.0.1"

defaultConfig {
    applicationId "net.brawtasports.brawtasportsgps"
    minSdkVersion 11
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

productFlavors {
    netball {
        applicationId "net.brawtasports.brawtasportsgps.netball"
        versionName "1.0"
    }

    football {
        applicationId "net.brawtasports.brawtasportsgps.football"
        versionName "1.0"
    }

}

sourceSets {
    main {
        java.srcDirs = ['src/main/java']
        res.srcDirs = ['src/main/res']
    }
    football {
        java.srcDirs = ['src/football/java']
        res.srcDirs = ['src/football/res']
    }
    netball {
        java.srcDirs = ['src/netball/java']
        res.srcDirs …

使用 Gson 将 JSON 字符串转换为 Java 对象时，我收到此警告。为什么我得到它，我该如何解决它？

这是我在代码中收到的警告：

Unchecked assignment: 
    'net.brawtasports.brawtasportsgps.model.JSONKeys' to 
    'net.brawtasports.brawtasportsgps.model.JSONKeys<net.brawtasports.brawtasportsgps.model.team.Object>'

这是我在运行时得到的错误：

java.lang.ClassCastException:
    com.google.gson.internal.LinkedTreeMap cannot be cast to
    net.brawtasports.brawtasportsgps.model.team.Object

这是我的代码：

  String jsonString = Preferences.readFromPreferences(ApplicationConstants.team_data,"");
    Gson gson = new Gson();
    JSONKeys<Object> teamMembers = gson.fromJson(jsonString, JSONKeys.class); //converts json string to java object
    Object players = teamMembers.getObject();//object is my custom class
    //ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(getActivity(),android.R.layout.simple_spinner_dropdown_item,players);
    ArrayAdapter arrayAdapter = new ArrayAdapter(getActivity(),android.R.layout.simple_spinner_dropdown_item,players.getPlayersSummary());
    player1.setAdapter(arrayAdapter);

这是我的 JSONKeys POJO 的代码：

   public class JSONKeys<T> {

private boolean Success;
private String Message;
private int ObjectIdentifier;
private T …
