I am running a shell script which calls a java class to get some data from database and create an excel report with that data.

If I don't run pro-guard on my project, everything is fine but if I run pro-guard and install .apk in device, I am getting above error.

I have got a few (4) error reports on my app from when the Android system decides to do the backup to Google cloud using the BackupAgent. I am using the SharedPreferencesBackupHelper.

I am receiving a 'Unable to instantiate activity' error when I try to load up my program. One thing that baffles me is the exact same code works on my older PC. I just built a new one with new eclipse / android SDK / etc. I have both machines running the same code, one works fine and the other gives this error. Any thoughts? Edit: One thing I notice in the stack is Caused by: java.lang.ClassNotFoundException: com.voldaran.puzzle.graBLOX.PopActivity in loader dalvik.system.PathClassLoader[/data/app/com.voldaran.puzzle.graBLOX-2.apk] It lists graBLOX-2.apk . Why is it using '-2.apk'? When I

This exception is reported 10/week, I tried to find solution but failed. I'm a little frustrated with this sort of exception, and searched all related posts. (P.S. I noticed that full name (android:name="com.example.AcraApplication") throw more exceptions than short one(android:name=".AcraApplication").) public class AcraApplication extends Application { public void onCreate() { ACRA.init(this); super.onCreate(); } <application android:name=".AcraApplication" android:icon="@drawable/app_icon" android:label="@string/app_name" > LogCat: java.lang.RuntimeException: Unable to instantiate

Hey guys. I am developing a client/server program where the client is an android device. The server has a listener class that reads an object from the input stream. I created a client software for another COMPUTER that sends a small object over a local network. Computer to Computer works perfectly fine , i read the object and printed the contents. However, the SAME code ported over to android (I rewrote it just in case) does not work. I construct an object (ANY object), which is serializable, and send it via the ObjectOutputStream. My server running on the computer does connect to the device,
