Android SDK无法启动

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.

Answer 1

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.

Answer 2

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

Answer 3

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.
