android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.yaron.myapplication"
        minSdkVersion 19
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false

推荐答案

有几件事需要检查.

如果您转到 Android Studio 中的终端窗口并 cd 到安装 sdk 平台工具的路径(类似于 C:AndroidSDKplatform-tools)并运行以下命令

if you go to the terminal window in Android Studio and cd to the path where your sdk platform tools are installed (something like C:AndroidSDKplatform-tools ) and run the following command

adb 设备

您是否列出了设备?如果不是，那么您的设备设置不正确，或驱动程序不正确.

Do you have a device listed? If not then you don't have the device setup properly, or the correct drivers.

在手机上确保您启用了开发者选项(转到设置->关于手机，然后点击内部版本号 7 次左右)

On the phone make sure that you have developer options enabled (go to settings->about phone and click on the Build Number 7 times or so)

启用后，进入设置下的开发选项，并确保启用 USB 调试.

Once you have enabled that go into the develop options under settings and make sure USB debugging is enabled.

如果adb devices 对您要连接的设备说无权限"，请确保先将其连接为 MTP 设备.这将隐式提示您导入计算机的指纹，并允许将来进行 USB 调试连接.

If adb devices said "no permission" for the device you are connecting, make sure to connect it as MTP device first. This will implicitly prompt you to import the computer's fingerprint and allow future connections for USB debugging as well.
