Android Studio 无法识别我的设备 - LG Spirit 4G

Android Studio doesnt recognize my device - LG Spirit 4G

我启用了开发人员选项,更新了驱动程序(说 OS win10),并且我按照文档的说明进行操作。我的清单:

  <application
    android:debuggable="true" //this line says it shouldnt be harcoded?
    android:allowBackup="true"
    android:icon="@drawable/ic_piano"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

以及构建 gradle 文件:

     android {
    // 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:2.2.2'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    } 
  }

  allprojects {
  repositories {
    jcenter()
  }
 }

 task clean(type: Delete) {
    delete rootProject.buildDir
 }
 android {
    buildTypes {
       debug {
        debuggable true
       }

从文档中复制的清单和构建代码。但它未能build.graddle。它说:期待'}'找到“ 我不知道这是什么意思,因为我已经完成了文档中所说的一切。我已经在 SO 中搜索了所有答案,但没有任何有效的答案......有什么想法吗? link: https://developer.android.com/studio/run/device.html

你搞砸了你的 build.gradle,它应该是这样的:

    // 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:2.2.2'

             // NOTE: Do not place your application dependencies here; they belong
             // in the individual module build.gradle files
         } 
  }

  allprojects {
       repositories {
           jcenter()
       }
  }

 task clean(type: Delete) {
    delete rootProject.buildDir
 }

请注意,这是您的顶级 build.gradle,它将位于您项目的根目录中。应该有 另一个 build.gradle 在一个可能叫做 /app 的文件夹里面,这是你添加和修改 android{} gradle clojure 的文件
