Most of the devices can run my app but I got this error report : <pre><code>java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.company.app/com.company.app.MainActivity}: java.lang.ClassNotFoundException: com.company.app.MainActivity in loader dalvik.system.PathClassLoader[/mnt/asec/com.company.app-1/pkg.apk] at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2755) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2854) at android.app.ActivityThread.access$2300(ActivityThread.java:136) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2179) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:143) at android.app.ActivityThread.main(ActivityThread.java:5068) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:858) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) at dalvik.system.NativeStart.main(Native Method) Caused by: java.lang.ClassNotFoundException: com.company.app.MainActivity in loader dalvik.system.PathClassLoader[/mnt/asec/com.company.app-1/pkg.apk] at dalvik.system.PathClassLoader.findClass(PathClassLoader.java:243) at java.lang.ClassLoader.loadClass(ClassLoader.java:573) at java.lang.ClassLoader.loadClass(ClassLoader.java:532) at android.app.Instrumentation.newActivity(Instrumentation.java:1034) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2747) ... 11 more </code></pre> I found there is a related answer: <a href="https://stackoverflow.com/questions/3090009/classnotfoundexception-android">ClassNotFoundException Android</a> but the question is, my exception occurs before any line of code i write, so how can I ensure the class loader is loaded?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
