无法解析符号“FragmentActivity”

Question

导入包时,FragmentActivity类有一个问题：

import android.support.v4.app.FragmentActivity;

android Gradle：

configurations {
    all*.exclude group: 'com.android.support', module: 'support-v4'
}
android {
    signingConfigs {
        CirclePong {
            keyAlias 'madtriangle'
            keyPassword 'piratamenu94'
            storeFile file('/Users/ManuGil/Documents/LibGDX/apk/CirclePong/circlepong.jks')
            storePassword 'piratamenu94'
        }

    }

apply plugin: 'android-library'
configurations {

}
repositories {
    mavenCentral()
}

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:25.1.1'
    compile 'com.android.support:support-v4:25.1.1'
    compile 'com.google.android.gms:play-services:10.2.0'
}

android {
    compileSdkVersion 25
    buildToolsVersion '25.0.2'
        }

请尝试从BaseGameUtile Gradle中删除此节

 configurations {
       all*.exclude group: 'com.android.support', module: 'support-v4'
 }

它阻止包含支持库。

当两个或多个模块之间存在依赖冲突时，就会使用此部分，因为这两个模块都包含支持库。
