我新安装的
Android项目启动了一个新的默认项目.每次我尝试启动应用程序这个错误发生:
的build.gradle(模块:APP)
apply plugin: 'com.android.application' android { compileSdkVersion 21 buildToolsVersion "21.1.2" defaultConfig { applicationId "com.example.jdevani.validationdemo" minSdkVersion 8 targetSdkVersion 21 versionCode 1 versionName "1.0" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro' } } } dependencies { compile fileTree(dir: 'libs',include: ['*.jar']) compile 'com.android.support:appcompat-v7:21.0.3' }
的build.gradle(项目:EmerGencyHelp)
// Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:1.1.0' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { jcenter() } }
我的错误是

请帮帮我
提前致谢,
解决方法
也许你不要在你的项目中正确添加suport-v4库.
检查这个:
检查这个:
>你将这个库添加到所有需要的模块中(如果有的话)
比您的项目中的模块多,如主模块和库
模块).
检查你不要添加这个库两次.
最后,如果没有解决您的问题,请尝试从导入的库列表和项目模块依赖列表中删除此库,并将其从一个源重新导入到项目中,然后尝试重新构建项目或重新启动IDE.我希望这样可以帮助你:)
