I downloaded Android Studio and attempted to launch the program.

This is running on Windows 7 64-bit with Java 1.7. During the installation my Java 1.7 is detected, and the rest of the installation goes through just fine. However, when attempting to launch the application from the desktop icon, nothing happens. Looking at the task manager, a new process from the CMD is loaded. This is because it's attempting to run the batch file studio.bat.

When I execute via CMD, I get the following error:

ERROR: cannot start Android Studio. No JDK found. Please validate either ANDROID_STUDIO_JDK, or JDK_HOME or JAVA_HOME points to valid JDK installation. ECHO is off. Press any key to continue . . .

I've attempted to open the idea properties file to see if there was something I could configure for this ANDROID_STUDIO_JDK or something like that. However, I found nothing. I hope some of you can let me know if you were able to install this or if you are having problems as well.

Adding a system variable JDK_HOME with value c:Program FilesJavajdk1.7.0_21 worked for me. The latest Java release can be downloaded here.

Additionally, make sure the variable JAVA_HOME is also set with the above location.

VB6 Installs just fine on Windows 7 (and Windows 8 / Windows 10) with a few caveats.

Here is how to install it:

  • Before proceeding with the installation process below, create a zero-byte file in C:Windows called MSJAVA.DLL. The setup process will look for this file, and if it doesn't find it, will force an installation of old, old Java, and require a reboot. By creating the zero-byte file, the installation of moldy Java is bypassed, and no reboot will be required.
  • Turn off UAC.
  • Insert Visual Studio 6 CD.
  • Exit from the Autorun setup.
  • Browse to the root folder of the VS6 CD.
  • Right-click SETUP.EXE, select Run As Administrator.
  • On this and other Program Compatibility Assistant warnings, click Run Program.
  • Click Next.
  • Click "I accept agreement", then Next.
  • Enter name and company information, click Next.
  • Select Custom Setup, click Next.
  • Click Continue, then Ok.
  • Setup will "think to itself" for about 2 minutes. Processing can be verified by starting Task Manager, and checking the CPU usage of ACMSETUP.EXE.
  • On the options list, select the following:
    • Microsoft Visual Basic 6.0
    • ActiveX
    • Data Access
    • Graphics
    • All other options should be unchecked.
  • Click Continue, setup will continue.
  • Finally, a successful completion dialog will appear, at which click Ok. At this point, Visual Basic 6 is installed.
  • If you do not have the MSDN CD, clear the checkbox on the next dialog, and click next. You'll be warned of the lack of MSDN, but just click Yes to accept.
  • Click Next to skip the installation of Installshield. This is a really old version you don't want anyway.
  • Click Next again to skip the installation of BackOffice, VSS, and SNA Server. Not needed!
  • On the next dialog, clear the checkbox for "Register Now", and click Finish.
  • The wizard will exit, and you're done. You can find VB6 under Start, All Programs, Microsoft Visual Studio 6. Enjoy!
  • Turn On UAC again

  • You might notice after successfully installing VB6 on Windows 7 that working in the IDE is a bit, well, sluggish. For example, resizing objects on a form is a real pain.
  • After installing VB6, you'll want to change the compatibility settings for the IDE executable.
  • Using Windows Explorer, browse the location where you installed VB6. By default, the path is C:Program FilesMicrosoft Visual StudioVB98
  • Right click the VB6.exe program file, and select properties from the context menu.
  • Click on the Compatibility tab.
  • Place a check in each of these checkboxes:
  • Run this program in compatibility mode for Windows XP (Service Pack 3)
    • Disable Visual Themes
    • Disable Desktop Composition
    • Disable display scaling on high DPI settings
    • If you have UAC turned on, it is probably advisable to check the 'Run this program as an Administrator' box

After changing these settings, fire up the IDE, and things should be back to normal, and the IDE is no longer sluggish.

Please follow the below steps to fix the problem..

  1. Go to settings and turn off your Developer Options.
  2. Restart your device.
  3. Go to settings again and turn on your Developer Options back (By hitting the Build Number multiple times).

Now you are able to install APKs from your Android Studio as you were earlier. Restarting the device is optional but better do that.

I had the same error. By selecting different parts of the project in the wizard the error would sometimes trigger and sometimes not.

Anyway, before that error there's a lot of "package android.* does not exist" warnings, so I decided to get rid of these first. Here's the workaround that worked for me.

Now, with these warning messages gone, the NullPointerException disappeared too! I was able to generate javadoc for the entire project, including links to referenced library projects, 3rd party library jars and Android framework classes.

theme "Theme.AppCompat.Light.DarkActionBar" is declared in modul "com.android.support:appcompat-v7"

so you need something like this in your build.gradle.

dependencies {
    compile 'com.android.support:appcompat-v7:22.1.1'
}

alternativly you can use "Theme.Holo.Light.DarkActionBar" instead which is part of newer android versions and does not need an extra modul.

"Theme.AppCompat.xxx" and "com.android.support:appcompat-v7" was created to allow old android versions like android-2.2 to user newer features introduced in newer android versions.
