即使安装了JDK 8，Android工作室也无法安装

Question

I just downloaded Google's new android studio bundle(x64 for Windows) and also installed JDK8 (C:\\Program Files\\Java\\jdk1.8.0_25) (x64 version).

But on the android studio setup it does not detect JDK and asks to locate its path. I located its path but still it says it is not valid.

I tried declaring new Environment variables (both system and User) but still I get same error.

I also tried in cmd, and it says that java & JDK is installed.

After that I reinstalled JDK 8 for windows x64 from Oracle. But no changes in android studio...

Please Help. !

Answer 1

I had the same problem. I discovered that it was caused because I installed the JDK while the Android Studio installer was still opened and at the prompt to load the location of the JDK. Closing the Android installer and then reloading it after the JDK installation had completed and was closed out, solved the installation problem for me.

Answer 2

While running Java 6 something I tried to install Android Studio. Android Studio did not find Java 7 or Java 8, so it asked me to install at least Java 7 and gave a link to Java 7. While the original instance of Android Studio Installer was still alive, it would not find Java 7 or 8. killing and restarting Android Studio Installer worked just fine. So install Java and restart the installer.

Answer 3

I have same error but i closely look into the note and then my problem solved :)

Answer 4

It needs JDK 7, as stated on the System Requirements page: http://developer.android.com/sdk/index.html#Requirements

Update:

For Android Studio 2.1, it needs JDK 8 for Windows or Linux, and JDK 6 for Mac.

Try following steps if it works.

1. goto the AndroidStudio installation folder.
2. goto bin folder and open studio.bat in text editor add set JAVA_HOME=C:\\Program Files\\Java\\jdk1.8.0//your java path
3. goto Start -> All Programmes -> Android Studio -> Right click on Android Studio and click on properties .
4. You will see the Target like < installation path>android-studio\\bin\\studio64.exe change it to <installation path>android-studio\\bin\\studio.bat

Answer 6

I solved this problem by closing the installation file, and open it again as an administrator. Pre over the need to set jdk.

在我的情况下，我使用java8并基于Doc我只需要添加以下内容：

 implementation "androidx.lifecycle:lifecycle-common-java8:$lifecycle_version"
