    <p>I am just trying to start development in Android. So, the problem is that when I try to launch an emulator by issuing the command <strong>emulator @A2</strong> , an emulator comes up on the screen. But even after waiting for as long as 2-3 hrs, all it shows is a black screen. Not even the android home screen or the android logo. Just a black screen. And while initially "adb devices" shows the emulator as offline.after 2-3 minutes the list of attached devices becomes blank.</p> <p>I searched all over net and tried all the steps mentioned there like kill and restart adb, install java/android in a directory without spaces, but to no avail.</p> <p>My Jdk and Android installations are in following folders:</p> <p>C:\Java32BitInstallation C:\AndroidSdkInstallation Here's the list of stuff I have downloaded/installed for it:</p> <ol> <li>Android SDK Tools, revision 13</li> <li>Android SDK platforms tools, revision 10</li> <li>SDK platform Android 4.0.3, API 15, revsion 1</li> <li>Jdk jdk-7u3-windows-i586</li> </ol> <p>In my <strong>path</strong> variable, I have added *C:\AndroidSdkInstallation\android-sdk\platform-tools\;C:\AndroidSdkInstallation\android-sdk\tools\;C:\Java32BitInstallation\;C:\Java32BitInstallation\bin*</p> <p>Also after reading somewhere from net I have added JAVA_HOME variable with its value as C:\Java32BitInstallation\ But still no use. </p> <p>I have both IntelliJ and Eclipse installed on my system. But since for starting the emulator, I am not using any of these, I dont suspect any foulplay with these.</p> <p>So, can anyone please help me with this stuff that's driving me crazy. I am trying for past 10-12 days and have not been able to start the emulator, let alone write my first "Hello world" program.</p> <p>Additional notes: My system is a windows 7 (64 bit) machine. Earlier I had installed 64 bit version of jdk, but the problem was present that time too. Now after searcching on internet, I uninstalled that and installed 32 bit version of Java. But, again no use. One thing, though, this 32 bit version of java (jdk 7 update 3), first install jre as part of jdk installation and then installs jre 7 . So now I have 2 folders: jre and jre7 in the C:\Java32BitInstallation directory. Could this have to do anthing with my emulator not turning up. Do I need to specify aditional environmetal variables or modify the existing one? Kindly help.</p> <p>BTW, did I mention the logcat shows nothing.</p>

    1. COI don't know if you managed to solve this issue. Recently I had the same problem. Try running emulator with `emulator -debug-init -logcat '*:v'`. This might lead you to the root cause. Mine was afailing ServiceManager. It appeared I had removed a few ServiceManager files.
