I am following this tutorial and I can make it work just fine, but when I try to update the UI to fit the new Holo.Light in android 4.2 the app crashes at launch, and I don't know why.
I have been searching for a way to update the UI but I could not get it to work.
I wonder if anybody could help me? tell me how? Give me a link that you know would work?
or even do it yourself?
i get this error log:

You are making a network call on the main thread. This is not allowed on Android 4.2, and is a really bad idea on earlier versions which do permit this. I have blogged about various mechanisms for moving network and other heavy calls off the main thread at http://blog.stylingandroid.com/archives/833.
Without seeing your code, I cannot begin to suggest which approach is the right one for you to use, but hopefully the information in my articles will help you in deciding upon the correct approach.
There are two Solution of this Problem.
1) Don't write network call in Main UIThread, Use Async Task for that.
2) Write below code into your MainActivity file after setContentView(R.layout.activity_main);
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
And below import statement into your java file.
import android.os.StrictMode;
and see below link for more information.

I have been working on my Android application for weeks now and suddenly it just will not launch. I get the same errors on my mobile device as well as on the Emulator. I have made backups of older versions off my application as I go along, and despite reloading these into eclipse I am still getting the same errors. I really do not understand and panicking. Please can someone advise?

Do you have declared the activitys in the manifest?
I have a project with Ionic working fine in iOS (emulator and device), web and with a problem in Android.
I have used to create the project:
ionic platform add android
I open the project with Eclipse, everything is Ok, no errors, and CordovaLib is loading fine.
When I try to deploy in my device, I have this error:

EDIT:
The plugins have not been copying to the Android Project :(
Help please ;) Thanks!!
I had the same problem,but solved using this way.After creating the project first I build the project using the command ionic build android, then import it.if its not working try this
1.Remove the platform using ionic platform remove android
2.Add the platform again,and run.
My app use tess-two (https://github.com/rmtheis/tess-two) library which uses native api. When I use separate tess-two or dropbox sync api, there is nothing happen. But my app need to use both libraries, and when I add two libraries at the same time, I got the exception with dropbox sync api like this:

I'm sure that I have copied all .so and jar library files of dropbox sync api into my libs folder. And I also refer this link Error in dropboxSync: findlibrary returned null, but it doesn't work. Is there any idea?
Update: my Android.mk of tess-two look like this ( I don't change anything from github source because I think two libraries don't reference each other):
LOCAL_PATH := $(call my-dir)
TESSERACT_PATH := $(LOCAL_PATH)/com_googlecode_tesseract_android/src
LEPTONICA_PATH := $(LOCAL_PATH)/com_googlecode_leptonica_android/src
# Just build the Android.mk files in the subdirs
include $(call all-subdir-makefiles)
Problem is solved by copying libDropboxSync.so from armeabi to armeabi-v7a folder but I don't know how it can work. More detail in my own question from dropbox 4rum
I downloaded UnboundID LDAP SDK and imported it to my Eclipse Android project. It make use of existing LDAPClient supplied with the SDK.
Build was successful. However, when I attempt to launch the application, it gives below run-time error and application would not launch.
I am new to Android and Eclipse. Hence, any help or tips shall be appreciated.
If there are any details required, please let me know. I can add it.

You need to make sure that the jar is exported when building .apk file.
In project properties, go to Java Build Path > Order and Export : fill the checkbox corresponding to the LDAP sdk
I want my Android app to behave as a client and listen on a particular port. None of the code I've tried works. I tried this tutorial to create a small chat app. The server side works fine, but the app crashes on my device. I have both my phone and server comp on VPN.
