关闭并重启Android Studio, 这种方法是最基本的，但不一定总是有效。

清除Android Studio的缓存。打开命令行，输入以下命令：

$ cd ~/Library/Caches/
$ rm -rf AndroidStudio*

清除Gradle缓存。打开命令行并输入以下命令：

$ rm -rf ~/.gradle/caches/

在项目中关闭即时运行（Instant Run），可通过以下步骤完成：

• 打开项目
• 打开Android Studio的'Preferences”（偏好设置）
• 转到'Build, Execution, Deployment”（构建、执行、部署） > 'Instant Run”（即时运行）
• 清除选择框：'Enable Instant Run to hot swap….”

指定Android Studio使用特定的JDK版本。在项目的build.gradle文件中添加以下代码。请注意，这只是一个示例，您需要根据本地设备上JDK所在的位置来修改路径。

android {
  ... 
  ...
  compileOptions { 
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
  
  // Change the JDK folder path to the correct location for your machine
  // The following path should be modified as per need. 
  //change /Applications/Android\ Studio.app/Contents/jdk//Contents/Home/ with path of your installed jdk
  //on my computer path was /Library/Java/JavaVirtualMachines/jdk1.8.0_251.jdk/Contents/Home/
  
  // windows users should replace jdk with jre
  //replace "Program Files" with the folder name where your jdk is installed
  //'"C:/Program Files/Java/jdk1.8.0_281"' is the path where wish to set JDK
  
  def jdkPath = "/Library/Java/JavaVirtualMachines/jdk1.8.0_251.jdk/Contents/Home/" 
  // Use the path which suits you
  kotlinOptions {
    jvmTarget = "1.8"
    javaHome = jdkPath
  }
  
  // Add path of JDK to system path
  //to add path to path variable on mac run command given below
  //export PATH="/Library/Java/JavaVirtualMachines/jdk1.8.0
