    copied!<p>I have been trying to get the OpenTok <a href="https://github.com/opentok/Android-Hello-World" rel="nofollow noreferrer">Android hello world</a> working but it keeps crashing on launch. After importing the Hello world project, I copied the opentok android sdk into the project and re-built the project in eclipse. The errors all went away but when I run it on my Galaxy Nexus, I get the following error:</p> <pre><code>02-02 10:01:39.321: E/AndroidRuntime(17238): FATAL EXCEPTION: main 02-02 10:01:39.321: E/AndroidRuntime(17238): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.opentok.helloworld/com.opentok.helloworld.MainActivity}: java.lang.ClassNotFoundException: Didn't find class "com.opentok.helloworld.MainActivity" on path: /data/app/com.opentok.helloworld-2.apk 02-02 10:01:39.321: E/AndroidRuntime(17238): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2106) 02-02 10:01:39.321: E/AndroidRuntime(17238): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2230) 02-02 10:01:39.321: E/AndroidRuntime(17238): at android.app.ActivityThread.access$600(ActivityThread.java:141) 02-02 10:01:39.321: E/AndroidRuntime(17238): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1234) 02-02 10:01:39.321: E/AndroidRuntime(17238): at android.os.Handler.dispatchMessage(Handler.java:99) 02-02 10:01:39.321: E/AndroidRuntime(17238): at android.os.Looper.loop(Looper.java:137) 02-02 10:01:39.321: E/AndroidRuntime(17238): at android.app.ActivityThread.main(ActivityThread.java:5039) 02-02 10:01:39.321: E/AndroidRuntime(17238): at java.lang.reflect.Method.invokeNative(Native Method) 02-02 10:01:39.321: E/AndroidRuntime(17238): at java.lang.reflect.Method.invoke(Method.java:511) 02-02 10:01:39.321: E/AndroidRuntime(17238): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:793) 02-02 10:01:39.321: E/AndroidRuntime(17238): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:560) 02-02 10:01:39.321: E/AndroidRuntime(17238): at dalvik.system.NativeStart.main(Native Method) 02-02 10:01:39.321: E/AndroidRuntime(17238): Caused by: java.lang.ClassNotFoundException: Didn't find class "com.opentok.helloworld.MainActivity" on path: /data/app/com.opentok.helloworld-2.apk 02-02 10:01:39.321: E/AndroidRuntime(17238): at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:65) 02-02 10:01:39.321: E/AndroidRuntime(17238): at java.lang.ClassLoader.loadClass(ClassLoader.java:501) 02-02 10:01:39.321: E/AndroidRuntime(17238): at java.lang.ClassLoader.loadClass(ClassLoader.java:461) 02-02 10:01:39.321: E/AndroidRuntime(17238): at android.app.Instrumentation.newActivity(Instrumentation.java:1054) 02-02 10:01:39.321: E/AndroidRuntime(17238): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2097) 02-02 10:01:39.321: E/AndroidRuntime(17238): ... 11 more </code></pre> <p>Am I doing something wrong?
