PO"Unable to instantiate activity" error
text
Body
copied!<p>One of my Android apps has about 100,000 users and, about 10 times a week, I get the following exception being reported to me via Google's market tool:</p> <pre><code>java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{org.rebm.asp/org.rebm.asp.MainActivity}: java.lang.ClassNotFoundException: org.rebm.asp.MainActivity in loader dalvik.system.PathClassLoader[/mnt/asec/org.rebm.asp-1/pkg.apk] at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2659) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2753) at android.app.ActivityThread.access$2500(ActivityThread.java:129) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2107) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:143) at android.app.ActivityThread.main(ActivityThread.java:4701) 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:868) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) at dalvik.system.NativeStart.main(Native Method) Caused by: java.lang.ClassNotFoundException: org.rebm.asp.MainActivity in loader dalvik.system.PathClassLoader[/mnt/asec/org.rebm.asp-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:1021) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2651) ... 11 more </code></pre> <p>From searching online, this error usually indicates something is wrong with the manifest file and the package names being used. However, I can't reproduce this error on my own devices or on the emulator. I only know of this error through the market tool. All I can conclude is that it's a rare error because I know lots of people are using the app and none of the reviews indicate it crashes.</p> <p>Does anyone know what the issue might be or how I can diagnose it?</p>
