I am trying to setup a android virtual device to test syncing with an activesync-server.
I followed these steps:
The problem is that syncing is not working at all, but there are no errors like connection errors ...
IMO the problem is that the virtual device only has a private IP, so the server never can send anything to it?
So I probably need some kind of forwarding, like here:
But I am not sure if that’s correct and I am also not sure which ports should be forwarded.
Here is the logcat, when I want to sync:

I don't think this is a problem with your networking setup. It looks like you have an error in your Sync code, that is causing the process to stop:
E/Inboxtest#example.com: Uncaught exception in EasSyncServicejava.lang.ArrayIndexOutOfBoundsException: length=32; index=32
E/Inboxtest#example.com: Sync ended due to an exception.

Wrap this code in a try/catch block to understand what is happening better.

I'm getting some non fatal errors on my logcat but no line numbers or anything else that can help me locate the error.
As you can see, I'm getting several, including Cursor finalized without prior close() and Window is full, but no idea how to find them.

Any tips?
Thanks!
This kind of errors are not exceptions thrown by the program and will therefore not contain a stack-trace. As a general rule of thumb you may find ways to optimize your code by carefully reading the error message and read into the subject concerning the error.
As far as I can see it is a problem with allocation of memory. I don't think you can pinpoint them to a specific position in your execution flow since it will probably occur at different points in execution. You can think about your code to see if you can find some memory optimization possibilities.
If you want to analyze your code thoroughly you may want to use a tool like 'Eclipse MAT'. Read this tutorial to learn how to use the tool
Do a global file search looking for text like ".query(" in your .java files.
That should lead you to places where a Cursor is returned and from there you should be able to determine where they are not being closed.
I am working with Google Maps v2 for Android.
I need to display some View over the map's marker, so I am updating its position every 16ms to keep 60fps.
And I got a problem with that code:
Point targetPosition = getMap().getProjection()
.toScreenLocation(mTrackingMarkerPos);
Because it seems that it causes explicitly calls to the System.gc() or Runtime.getRuntime().gc().
So I got this in log output:
03-12 15:00:24.362 19135-19135/my_fake_package_name D/dalvikvm﹕ GC_EXPLICIT freed 122K, 10% free 12710K/14116K, paused 11ms+11ms, total 115ms

As you can see, GC_EXPLICIT can pause my app for about 100ms!
So my approach to keep 60fps is not achievable because of Google Maps v2 :(
If I comment that line, GC_EXPLICIT calls will disappear. I think that problem in Google Maps v2, I checked their .class files but I did not find any calls to System.gc, so may be I am wrong...
If you know how to find call to the System.gc() I will be glad to know it too, or guys from Google can help me with this issue?
P.S. Asked this on gmaps-api-issues: https://code.google.com/p/gmaps-api-issues/issues/detail?id=6483&thanks=6483&ts=1394624273
I have spent long time on this, this is driving me craze.
My app works all fine on android 4.1 and below. But it have a big problem running on android 4.2.2
At some point the app just start a endless flicking or twinkling, until it eat up all memory of the phone, then the phone died.
I have no idea where this problem is triggered, i don't know which line of code cause this strange problem. Because it has not bad log at all, it runs from onCreate to the final line of onResume and its all fine, but after that it just jumped in to onDestroy automatically, then run into onCreate again, it's an endless loop.
During the loops, all logs i have got is like this:

Any words or recommendations to help me find out where the problem is are appreciated.
Thanks in advance.
Finally i solved this problem by myself.
In my case, it caused by the abuse of
updateConfiguration()
i use it to manage language in each activity inside
onConfigurationChanged()
Once the change of the orientation triggered the onConfigurationChanged(), inside it will call updateConfiguration() which will trigger onConfigurationChanged() again, that will running into an endless loop.
So carefully review your use of these two functions, you will find something.
I want to receive updates from GPS, but i can't. Method onLocationChanged isn't calling. In this application i using Google Maps API, too. I don't know, maybe it is some cause of my problems.
It's code about GPS in MainActivity:
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
final LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location)
{
txtLat.setText("Latitude: " + String.valueOf((int)(location.getLatitude())) + ","
+ String.valueOf(((location.getLatitude() * 100) % 100)) + " degrees");
txtLong.setText("Longtitude: " + String.valueOf((int)(location.getLongitude())) + ","
+ String.valueOf(((location.getLongitude() * 100) % 100)) + " degrees");
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
};
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
and in Manifest i have declared these permissions:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
and other that Google Maps API v2 required

If you're attempting to retrieve the location using the GPS provider, and you're inside a building or have lousy GPS reception, the onLocationChanged will never be called.
There will be no automatic fallback to Wifi or celltower.
Always check what kind of provider you are using, even when specifying criteria.
Google has released a bunch of new Location APIs through Google Play Services that offers more efficient ways of retrieving user location (improving accuracy and battery-life).
I suggest you take a look at those and follow the Retrieving the Current Location tutorial (it includes a sample app that you can download).
I see a lot of this:
06-19 17:29:11.911: DEBUG/dalvikvm(10028): GC_FOR_MALLOC freed 729K, 54% free 3490K/7431K, external 0K/512K, paused 39ms

repeatedly in the log. Is there a way to not show the Dalvik debug messages?
Simply set a logcat filter. You can do this graphically in Eclipse as well.
