Android SDK won't start

Question

I have installed java jdk 1.8 and later the android SDK. Android SDK manager won't open, it flashes for a second and nothing else happen. By running android.bat i get the following error:

C:\android\tools>android.bat

Exception in thread "main" java.lang.UnsatisfiedLinkError: no     swt-win32-3550 or
        swt-win32 in swt.library.path, java.library.path or the jar file

        at com.android.sdkmanager.Main.run(Main.java:150)
        at com.android.sdkmanager.Main.main(Main.java:116)

I have set the environment variable:

JAVA_HOME > C:\Program Files\Java\jdk1.8.0_102.

Installed, reinstalled, redownloaded both java and android sdk, run as administrator, disabled antivirus, also tried many solutions found here without luck.

OS type and version, memory (RAM), Eclipse version, where you downloaded it from... all good things to know... — Jon Goodwin, Jul 21 '16 at 16:57
Win7 ultimate 64bit, 8gb, not using Eclipse. Downloaded from official websites. thanks. — im7xs, Jul 21 '16 at 16:58
the second line of your debug says: org.eclipse.swt.internal.Library.loadLibrary — Jon Goodwin, Jul 21 '16 at 16:59
don't have ecplipse intalled, I use b4a maybe this install some eclipse component. yes jdk 8 — im7xs, Jul 21 '16 at 17:04
I repeat again, what are you trying to do ? without android eclipse or studio ? — Jon Goodwin, Jul 21 '16 at 17:08
I use a RAD called basic4android, and it requires JAVA and ANDROID SDK. I have been using this from years, now this problem happen with my new laptop. The software have always worked perfectly on win7. — im7xs, Jul 21 '16 at 17:10
By the way it is very naughty to use the JDK with android, but it does work if you know what you are doing (I do it) but then I am a very naughty boy ;O) — Jon Goodwin, Jul 21 '16 at 17:11
i.c. I think you need to get the WHOLE thing (then delete stuff you don't need) meaning a full eclipse or studio download WITH SDK integrated. And NDK for the full experience. — Jon Goodwin, Jul 21 '16 at 17:13
I think i need only the android SDK manager to works to continue my work. Not eclipse, thaks for your recommandations. — im7xs, Jul 21 '16 at 17:16
but what you are downloading HAS Eclipse dependencies... that's why I asked where you are downloading it from, you see ? — Jon Goodwin, Jul 21 '16 at 17:17
You said you were using official sites, https://developer.android.com/index.html has android in the tilte, quite a big clue. — Jon Goodwin, Jul 21 '16 at 17:25
I dowloaded android sdk from developer.android and java from oracle ofc :') — im7xs, Jul 21 '16 at 17:26

You could try installing Android Studio, which should guide you through the setup and usually results with a working Android sdk. If the studio itself isn't desired, remove it but not the sdk when you are done.

It appears that my use of adk may not be quite right, the technical definition appears to be the Accessory Developement Kit, so adk may be ambiguous. – TheNumenorean Jul 21 '16 at 17:21
Not the best way but i resolved the problem by installing Studio. thanks. – im7xs Jul 22 '16 at 11:25

Add the following environment variables

ANDROID_SDK_ROOT - where you installed your sdk

Update your PATH variable to include this:

;%ANDROID_SDK_ROOT%/tools;%ANDROID_SDK_ROOT%/platform-tools;%JAVA_HOME%/bin

How do i Update my PATH variable? – im7xs Jul 21 '16 at 16:47
same place where you set environment variable `JAVA_HOME` (assuming you're on windows here) – Bill Jul 21 '16 at 16:49
I have added ANDROID_SDK_ROOT to be C:\android, but it looks you are talking of two different things. I am new of this. – im7xs Jul 21 '16 at 16:51

Keep in mind, too, that Java 8 isn't fully supported. In fact, no version of android prior to N (which is just a preview) supports Java 8 at all. Even Android N doesn't support every single language feature. See details on how to use Java 8 in Android and which of its features will be supported in N here: https://developer.android.com/preview/j8-jack.html

It's not possible to target Android N for a "real" app yet since there are no physical devices to run it, so I suggest sticking with JDK 1.7 for now.

The same happen with java SE 7. beside if java 8 is supported or not the problem is that the sdk manages won't start. – im7xs Jul 21 '16 at 17:02
Either way, I don't recommend continuing to try to get it running with JDK 1.8, that'll just cause you further problems. – EJoshuaS - Stand with Ukraine Jul 21 '16 at 17:05
