在成功地将Eclipse-Android-Project导入到“Android Studio 1.4”后,我得到了错误

"Please select Android SDK"

当我点击按钮在模拟器中运行应用程序时,我找不到任何方法来这样做。

当我点击“run”时,这个对话框就会打开:

这是“项目结构”对话框:

我现在该怎么办?


当前回答

在我的例子中,我在项目级别build.gradle中有一个依赖项的双重声明。一旦我删除它,做了一个Gradle同步,它工作。

其他回答

在我的情况下,没有选择java sdk版本的项目结构-

我必须选择-

1.源兼容性(1.7)

2.目标兼容性(1.7)

如图所示。

只需进入(应用程序级别)构建。gradle文件,给一个空白的地方,然后点击同步,一旦gradle显示同步完成,那么错误将会消失

这对我很管用。

文件->设置-> Android SDK -> Android SDK位置编辑-> Android SDK

After opening my project in Android Studio, I opened the App version of the build.gradle file, located in the Gradle Scripts folder of the Project. When I hovered my mouse pointer over the buildToolsVersion number, a tooltip popped, indicating that the version of Android Build Tools needed to be upgraded (see screenshot). I changed the value of the buildToolsVersion to the one identified by the error (27.0.2) and the problem was solved. The original error (Please select Android SDK) went away and the project compiled successfully, again. Although this solution was mentioned previously, the exact steps seemed to be missing, so hopefully this clears up any doubt. I guess the root cause for this problem is that a new version of the build tools were released but Android Studio did not trigger any notification to me, which would have indicated that I should manually fix this (since Android Studio does not seeem to have the ability to upgrade this build.gradle file internally), which leaves the onus on the user to find the problem and fix it.

点击这个图标来同步gradle

或者编辑你的gradle模块,然后同步
