Body
I am working on application which is host on android market. Sometimes (once a month ) I got a crash report: <blockquote> Unable to instantiate application java.lang.ClassNotFoundException </blockquote> App downloads are between 10,000-50,000. I don't know why this exceptions raise on some devices not all ( I tested it on 3 different devices & I couldn't re-produce it at my end). I read articles/suggestions on different android forums regarding the issue but I didn't succeed in solving it. Does anyone face similar issue & suggest me what should I do? Note: I am extending application class like this <pre><code>public class MyApplication extends Application { } </code></pre> I register it in the manifest.xml like this <pre><code><application android:icon="@drawable/app_icon" android:label="@string/my_app_name" android:name="MyApplication"> </code></pre> Stack Trace : <pre><code>java.lang.RuntimeException: Unable to instantiate application com.xyz.MyApplication java.lang.ClassNotFoundException: com.xyz.MyApplication in loader dalvik.system.PathClassLoader[/mnt/asec/com.xyz-1/pkg.apk] at android.app.ActivityThread$PackageInfo.makeApplication(ActivityThread.java:650) at android.app.ActivityThread.handleBindApplication(ActivityThread.java:4238) at android.app.ActivityThread.access$3000(ActivityThread.java:126) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2076) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:4633) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:858) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) at dalvik.system.NativeStart.main(Native Method) Caused by: java.lang.ClassNotFoundException: com.xyz.MyApplication in loader dalvik.system.PathClassLoader[/mnt/asec/com.xyz-1/pkg.apk] at dalvik.system.PathClassLoader.findClass(PathClassLoader.java:243) at java.lang.ClassLoader.loadClass(ClassLoader.java:573) at java.lang.ClassLoader.loadClass(ClassLoader.java:532) at android.app.Instrumentation.newApplication(Instrumentation.java:942) at android.app.ActivityThread$PackageInfo.makeApplication(ActivityThread.java:645) </code></pre> I don't know why application crash on some devices not all.

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.
