Hello. If app has well defined BackupAgent class with definition in manifest, the error suddenly occur randomly. (signed/unsiged same but maybe not debug mode).
I tried find solution through web, but everybody screaming about this error with no answer. The sample reference links from Stackoverflow are below -http://stackoverflow.com/questions/7506981/how-come-i-get-classnotfoundexception-when-backupagent-tries-to-start -http://stackoverflow.com/questions/7641765/mysterious-classnotfoundexception-when-android-system-engage-backupagent -http://stackoverflow.com/questions/6147241/android-app-classnotfoundexception-for-main-activity -http://stackoverflow.com/questions/3781151/java-lang-classnotfoundexception-on-working-app (and you can find more with keywords 'backupagent classnotfoundexception') Does anyone know solution to avoid this unexpected error?? (All the source code and manifest is all okay surely). Here is the log file. -------------------------------- E/ActivityThread(1954): Agent threw during creation: java.lang.ClassNotFoundException: com.company.appname.mybackuphelper in loader dalvik.system.PathClassLoader[/data/app/com.company.appname-1.apk] W/dalvikvm(1954): threadid=1: thread exiting with uncaught exception (group=0x4001e578) E/AndroidRuntime(1954): FATAL EXCEPTION: main E/AndroidRuntime(1954): java.lang.RuntimeException: Unable to create BackupAgent com.company.appname.mybackuphelper: java.lang.ClassNotFoundException: com.company.appname.mybackuphelper in loader dalvik.system.PathClassLoader[/data/app/com.company.appname-1.apk] E/AndroidRuntime(1954): at android.app.ActivityThread.handleCreateBackupAgent(ActivityThread.java:1895) E/AndroidRuntime(1954): at android.app.ActivityThread.access$3200(ActivityThread.java:117) E/AndroidRuntime(1954): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1030) E/AndroidRuntime(1954): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime(1954): at android.os.Looper.loop(Looper.java:130) E/AndroidRuntime(1954): at android.app.ActivityThread.main(ActivityThread.java:3687) E/AndroidRuntime(1954): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime(1954): at java.lang.reflect.Method.invoke(Method.java:507) E/AndroidRuntime(1954): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:847) E/AndroidRuntime(1954): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:605) E/AndroidRuntime(1954): at dalvik.system.NativeStart.main(Native Method) E/AndroidRuntime(1954): Caused by: java.lang.ClassNotFoundException: com.company.appname.mybackuphelper in loader dalvik.system.PathClassLoader[/data/app/com.company.appname-1.apk] E/AndroidRuntime(1954): at dalvik.system.PathClassLoader.findClass(PathClassLoader.java:240) E/AndroidRuntime(1954): at java.lang.ClassLoader.loadClass(ClassLoader.java:551) E/AndroidRuntime(1954): at java.lang.ClassLoader.loadClass(ClassLoader.java:511) E/AndroidRuntime(1954): at android.app.ActivityThread.handleCreateBackupAgent(ActivityThread.java:1864) E/AndroidRuntime(1954): ... 10 more W/asset(143): Asset path /data/app/com.company.appname-1.apk is neither a directory nor file (type=1).
