即使下载JDK 1.7和安装它后，我仍然有这个错误

Answer 1

您的问题将通过这个属性targetCompatibsility待提高，必须targetCompatibility

compileOptions { 
    sourceCompatibility JavaVersion.VERSION_1_7 
    targetCompatibility JavaVersion.VERSION_1_7 
} 

顺便说一句，你确定鸵鸟政策需要定义里面的一些依赖您build.gradle文件：

dependencies { 

     ??? 
} 

Answer 2

虽然你有一个错字，真正的问题是这样的：

compileOptions { 
    sourceCompatibility JavaVersion.VERSION_1_7 
    targetCompatibility JavaVersion.VERSION_1_7 
} 

应该是Android的{}闭包像这里面：

android { 
    compileSdkVersion 19 
    buildToolsVersion "22.0.1" 


    defaultConfig { 
     applicationId "com.myapp.new" 
     minSdkVersion 19 
     targetSdkVersion 19 
     versionCode 51 
     versionName "2.0.5" 
    } 

    //FIX 
    compileOptions { 
     sourceCompatibility JavaVersion.VERSION_1_7 
     targetCompatibility JavaVersion.VERSION_1_7 
    } 

    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.org' 
     } 
    } 
}
