Having searched here and elsewhere for answers to my problems, I\'m still unable to fix this.
I\'ve installed Eclipse, ADT Plugin, and the Android SDK. My problem is
Follow these steps and it help for me after a long time with all ways above not effect on windows7 64-bits, no need to have JAVA_HOME system variable or edit android.bat
Download Android Studio within Android SDK, Java JDK 64 bits and Java JRE x86
Install Java JRE first, then install Java JDK 64 bits, and the Android Studio last.
Now you start Android Studio first (64 bits version) it require to have JAVA_HOME setting to run JVM, just copy the jdk.x.x.x(version) folder (my PC: jdk1.8.0_25 from "C:\Program Files\Java\")folder to Android Studio folder and rename that folder (in Android Studio) to "jre" (jdk1.8.0_25 -> jre).
Now it work for me to open Android SDK Manager from anywhere, if you want to use eclipse (not official now) just copy the java jre.x.x.x(version) x86 folder (from where you install before) to Eclipse and rename to "jre". After coping, choose the Android SDK path in Eclipse to use, It works for both Android Studio and Eclipse.
Mind your antivirus if still refusing you (remove antivirus and install after you sure it not cause problem)!
