Title Body

Can anyone tell me how I should read the errors in Logcat? I'd like to understand where my problem is. At the moment, I tried to read it but can't find the cause of the crash. Here's the Logcat I don't understand: 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): FATAL EXCEPTION: main 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.paad.whereami/com.paad.whereami.WhereAmI}: java.lang.NullPointerException 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1647) 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1663) 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): at android.app.ActivityThread.access$1500(ActivityThread.java:117) 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:931) 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): at android.os.Handler.dispatchMessage(Handler.java:99) 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): at android.os.Looper.loop(Looper.java:130) 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): at android.app.ActivityThread.main(ActivityThread.java:3683) 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): at java.lang.reflect.Method.invokeNative(Native Method) 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): at java.lang.reflect.Method.invoke(Method.java:507) 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:839) 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:597) 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): at dalvik.system.NativeStart.main(Native Method) 05-18 18:29:44.160: ERROR/AndroidRuntime(2145): Caused by: java.lang.NullPointerException 05-18 18:29:44.16
