Filter log by text?

I am using adb shell logcat -v time filename command programmatically to store logs into a file on an android device.
There are some internal logs for memory releasing activities which are stored under " dalvikvm " tag. (See the logs below). I don't have any problem with these logs but due to these logs, the log file gets heavier.
So my concern is reduce logs which have GC_CONCURRENT freed or WAIT_FOR_CONCURRENT_GC text in it.
I also tried to reduce logs by using it's tag, but it removes all logs related to that tag. I don't want to loose required tags under same tag name. I just don't want the logs which have GC_CONCURRENT freed or WAIT_FOR_CONCURRENT_GC text in it.
Is there any way or any adb command to resolve this problem. Thanks in advance.

EDIT
I am using
adb shell logcat -v time | grep -v \"GC_CONCURRENT\\|WAIT_FOR_CONCURRENT_GC\" > " + filename command.
It was working when I gave filename as my computer's local path.
But when I tried same with android device /data/data/packagename/filename.txt, it was not working.
It says that bash: /data/data/packagename/filename.txt : No such file or directory Can anybody suggest solution for that.

Don't forget that you can use host side utilities with the output from logcat. I would recommend using grep. In particular, with it's -v/--invert-match option.
adb logcat | grep -v "GC_CONCURRENT\|WAIT_FOR_CONCURRENT_GC" > filename

The command to print specific logs using tag names. *:S which dont read logs related to GC_CONCURRENT freed and WAIT_FOR_CONCURRENT_GC
Syntax
adb logcat TAG_NAME:PRIORITY
Below line displays only logs with ActivityManager, MY_CUSTOM_TAG.. tags
adb logcat ActivityManager:I MY_CUSTOM_TAG:D ANOTHER_CUST_TAG:D *:S
S — Silent (highest priority, on which nothing is ever printed)

UPDATED Missed dumping to file.
Dump to file
`adb logcat -d ActivityManager:I MY_CUSTOM_TAG:D ANOTHER_CUST_TAG:D *:S > filename.txt`

Xamarin.Android application doesn't start the second time

I've created a simple application with Xamarin trial edition, which just shows a splash screen. After I hit "Run" in Xamarin studio it deploys and runs just fine, but if I click "Home" on the device and try to run application from the application list - screen flickers for a moment and application gets terminated, no breakpoints get hit on the second run. This is true for both emulator and a physical device.
I doubt it matters, but my code is as following.
Layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:minWidth="25px"
android:minHeight="25px">
<ImageView
android:src="#drawable/splash"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/imageView1" />
</LinearLayout>
Activity:
using Android.App;
using Android.OS;
using System;
using Android.Views;
namespace MyApplication.Activities
{
[Activity(Label = "My application", MainLauncher = true)]
public class SplashActivity : Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
RequestWindowFeature(WindowFeatures.NoTitle);
SetContentView(Resource.Layout.Splash);
}
}
}
Does the problem occur because it's a trial edition of Xamarin?

Ok, it looks like trial edition is indeed causing my problems. Adb logcat had lines:

Although, trial splash screen states, that build will work for 24 hours - it expires immediately for some reason. Oh well, I can live with that.
Update:
Yep, problem went away after I purchased and activated a license.

Debugging on phone

I have an app that I have been using for a long while now. It's open source and fell out of development. I started modifying it when it broke and it worked fine on my Epic Touch. I recently picked up the Sprint Note 2 and installed it. It forced closed on me. I decided "OK lets see whats going on and why its FCing". I ran it in an emulator 4.1.2 and it worked fine. When I tried to debug it in eclipse using the real phone my logcat showed problems and never loaded:

I tried wiping the cache, chmoding the folders, but nothing worked. I changed to a different project to see if it was that project but it did the same thing.
Does anyone have any ideas on what the problem could be and how to fix it?

INSTALL_FAILED_DEXOPT error when installing stock ICS Launcher on Samsung Galaxy S3

I have a Samsung Galaxy S3 and I've built the stock AOSP ICS Launcher2 app. I then tried to install the apk via "adb install" but I get an "INSTALL_FAILED_DEXOPT" error when I do that. The device logcat is as follows:

What could I have done wrong?
Thanks.

You need to increase the Android emulator's memory capacity, there are 2 ways for that:
1- Right click the root of your Android Project, go to "Run As" then go to "Run Configurations..." locate the "Android Application" node in the tree at the left, then select your project and go to the "Target" tab on the right side of the window look down for the "Additional Emulator Command Line Options" field (sometimes you'll need to make the window larger) and finally paste "-partition-size 1024" there. Click Apply and then Run to use your emulator.
2- Go to Eclipse's Preferences, then Select “Launch” Add “-partition-size 1024” on the “Default emulator option” field, then click “Apply” and use your emulator as usual.

unavailable shared library com.google.android.maps; failing! - android device

I'm trying to install my apk (which uses google maps) in android device. Its not getting installed. when i collect the log from the device it shows "unavailable shared library com.google.android.maps; failing!"
how to solve the above problem.?
I have given following line inside application tag.
<uses-library
android:name="com.google.android.maps"
android:required="true" >
</uses-library>
Following is my logs

Guess it is an issue with the device. Refer http://innovator.samsungmobile.com/bbs/discussion/view.do?platformId=0&parentCategoryId=0&messageId=101074&boardId=10. Try loading maps library externally.

In case with real device try remove from manifest file:
<uses-library android:name="com.google.android.maps" />
