[Q] Not able to install the SDK packages, coz SDK blinks for a sec and then closes.

So, I am sorry, if this is a stupid question, I am novice here. I am trying to run SDK manager on windows 7, 32-bit os. It's already installed. Whenever I try running SDK manager, It flashes for a sec and disappears. When I tried executing android.bat from tools, what I got was :
C:\Program Files\Android\tools>android
[INFO] Starting Android SDK and AVD Manager
'xcopy' is not recognized as an internal or external comman
operable program or batch file.
No command line parameters provided, launching UI.
See 'android --help' for operations from the command line.

General tip
If you double click some techie program on Windows and see it just appear and disappear like that, it usually means that this program is meant to be run in a command line window.
So go to All Programs -> Accessories -> Command Prompt and open that
Then go to wherever that program is installed and run it from there.
Oh, and note that Android development needs the JDK, not the JRE version of Java, The JDK contains all the extra parts needed for Java software development in general, including key parts needed by the Android SDK.
While the JRE can be downloaded from www java com , the JDK is only available from java.sun.com .
P.S.
Sorry for not making proper links, but I have not made enough posts to allow them yet.

[Q] change API level on apk

hello
can somone please help me a little. i want to change the API level from an apk to work on my 2.2 android device.
i downloaded sdk manager and downloaded the android 2.2 thingys. then i downloaded eclipse and started it and i installed the sdk following the offival development guide. but how can i now change api level off that app? can someone please give me a guide on what i need to do or if i missing some more plugins or so;ething. i am complete noob here but would like to try it to get that app to work on my device as i get parse error when trying to install.
thanks in advance

If you do not have source code for the apk (which I am assuming you don't), than I do not think you can just change the supported API level.
If the app does not support Android 2.2 (API level 8), than you can try following things:
1. Start ADB (adb.exe) from \android-sdk-windows\platform-tools and run following command
adb install <your apk file> after connecting your device to you computer.
This should install the apk. Application may crash if it uses certain API not supported in API level 8.
2. Just email the APK file and try to open your email from the device and insall there. You will sill run into the same issue of app crashing if it uses features not supported in API level 8.
Hope this helps.

can't load/run android sdk

Win7-64
Cannot seem to load the android sdk. I have downloaded the Java SDK SE 7u5 and the JRE 7u5 and installs seem ok. But when I try to execute the android sdk (installer_r20.0.1-windows.exe) I get the error "Java SE Development Kit (JDK) not found. Error: Failed to find Java version for 'c:\windows\system32\java.exe'"
I then added a path in the environment variables as JAVA_HOME to point to this c:\windows\system32\java.exe' but still refuses to load.
Have tried reset, reboot and no go. I have also searched the FAQ but did not locate an answer.
My intent is to work with the Android system for the Google Nexus 7 tablet.
Can anyone please point me to a resolution? Thanks!

First, make sure that the file java.exe is in this folder "C:\WINDOWS\system32\".
If this file is there, try to run "C:\WINDOWS\system32\java.exe -version" and make sure that you see the message java version "1.7.0_05"
If not - just reinstall java

Thanks - This works:
java version "1.7.0_5"
Java(TM) SE Runtime Environment (build 1.7.0_05-b06)
Java HotSpot(TM) 64-bit Server VM (build 23.1-b03, mixed mode)

if the problem hasn't been solved yet just try to install 32-bit version java (before remove 64-bit version)

Your JAVA_HOME should never point to /system32, otherwise you messed up the Java installation. Download the Java JDK from Oracle, and install it to its own folder.

[Completed] [Q] Android emulator not responding after a while

I have a script that installs an apk file, launches it, and uninstalls it afterwards (using adb) on the android emulator. (After installation I get a response from the terminal: rm failed for -f, No such file or directory while installing, but I don't think this is a problem) I repeat this for several apk files. But when I launch the android emulator, several minutes to several hours later, the emulator is not responding anymore. The spinning pinwheel appears, the only way to quit is to kill it via the terminal (using kill -9).
I have tried to change the two possible CPU/ABI Settings of an AVD to (ARM and Intelx86), but both settings result in the same problems. I have also tried different API levels (19 and 21), but also no luck there.
As I am running the emulator on a Mac, I thought the problem may be related to my OS, so I performed the same thing on a computer running Ubuntu. The same problem appears on both devices.
I have also captured the logcat files, but there are no similar error messages across these files.
These are the parameters that I am using: Android SDK / AVD Manager on Mac OSX10.10 (64 bit) with Java version 1.7.0_65 and Ubuntu 14.04 (64 bit) with Java version 1.8_0.25
Any idea (why or) how to figure why the emulator is not responding anymore?
Any help would be appreciated.

[Completed] Just Getting Started with Android Development Studio

I've downloaded the Dev Studio then it says I need the JDK. So, I downloaded it and now it's saying I need the JVM. The dialog box also says if I have already downloaded the JDK then I have to go into System Settings and point to it. How do I do that?

Hi there and welcome to Assist,
Here is few guides where you can start from:
