Install Android Studio Win7

The long-awaited Google I/O 2013 conference did not bring us Android5.0 or Adnroid4.3, but brought about Android Studio. Although it is a preview version, it is based on Intellij IDEA, however, developers are also excited. It seems that Google has to pay attention to developers.

As a newbie studying Android development, I learned about the release of Android Studio, so I can't wait to try it out. First, install it in Linux, and there is no difficulty in installing it. I feel that the so-called graphic interface is not bad. When I install it in Win7, because I have installed Eclipse before, during the installation, it can automatically find the installed jdk (1.7), after the installation is complete, the environment is configured, and then restart (do not forget to restart it to make the set environment variables take effect ). When you are excited to open the file, double-clicking the exe file does not respond. Then run cmd and run data studio. The result is displayed.

No JDK is found. Didn't you automatically find the JDK installation directory at the beginning of the installation? Let's look at it later. Is there a problem with setting the variables ANDROID_STUDIO_JDK, JDK_HOME, and JAVA_HOME.

After some settings, shut down, restart, or cannot be opened. Online Search, du Niang is not powerful, or g brother, because it is a new thing, there are not many related content on the Internet, just found on StackOverflow, and it is also the same as the problem I encountered, I don't believe that JDK 1.6 requires JDK 1.7. It has been so long and is not supported yet. Programmers have a more frustrated heart, the more difficult the more they want to forward.

Finally, I found a bat file in the bin directory under the installation directory: studio. bat. When I opened it, I realized that there must be a problem with the environment variable settings. Please refer to the content of studio. bat:

Everything is caused by the setting of environment variables. see why. In addition, it should be noted that the sdk must be upgraded to version 22 before it can be used. This is not clear (as I have not explained on the official website) because it has been upgraded to the new version before it is installed, if not, upgrade it. My three environment variables are set as follows (three variables are set for the sake of insurance ):

JAVA_HOME: D: \ jdk \ bin; D: \ jdk \ jre \ bin; D: \ jdk \ lib \ tools. jar; D: \ jdk \ lib \ dt. jar;

JDK_HOME: D: \ jdk \; D: \ jdk \ bin; D: \ jdk \ jre \ bin;

ANDROID_STUDIO_JDK: D: \ jdk

I hope you can help me try new things. It's not well written. Please don't scold me. Besides, I have a 64-bit Win7 system. Good luck to everyone.
