Android Studio-无法解析符号“ v7”

Question

我正在尝试从Eclipse迁移到Android Studio以进行android应用程序开发。 但是很难配置它。

解压下载的android-studio我将其放到/usr/local 。 然后创建一个新项目。 但是无法识别以下进口。

import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;

我的应用程序结构是

local.properties是

sdk.dir=/usr/local/android-studio/sdk

默认的build.gradle是

  1 buildscript {
  2     repositories {
  3         mavenCentral()
  4     }
  5     dependencies {
  6         classpath 'com.android.tools.build:gradle:0.7.+'
  7     }
  8 }
  9 apply plugin: 'android'
 10 
 11 repositories {
 12     mavenCentral()
 13 }
 14 
 15 android {
 16     compileSdkVersion 19
 17     buildToolsVersion "19.0.0"
 18 
 19     defaultConfig {
 20         minSdkVersion 7
 21         targetSdkVersion 19
 22         versionCode 1
 23         versionName "1.0"
 24     }
 25     buildTypes {
 26         release {
 27             runProguard false
 28             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
 29         }
 30     }
 31 }
 32 
 33 dependencies {
 34     //compile 'com.android.support:support-v4:18.0.+'
 35     compile 'com.android.support:appcompat-v7:+'
 36 }

在Appcompat上发现了类似的问题/使用android studio添加了一个库，但是解决方案compile 'com.android.support:support-v4:18.0.+'前提是该方法对我不起作用。

在$ gradlew build ，出现以下错误

FAILURE: Build failed with an exception.

* Where:
Build file '/backup/workspace.programming/workspace.android/Add2Wallet/Add2Wallet/build.gradle' line: 9

* What went wrong:
A problem occurred evaluating project ':Add2Wallet'.
> org/gradle/tooling/provider/model/ToolingModelBuilderRegistry

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

另一个问题是，当我在android-studio中点击Sync Project with Gradle files ，出现以下错误

23:08:10 ExternalSystemException

         Unable to start the daemon process.
         This problem might be caused by incorrect configuration of the daemon.
         For example, an unrecognized jvm option is used.

似乎V7依赖于V4支持。您不能仅使用V7。 并检查您的android支持库是最新的吗？
