**
I was recomended to use ActionBar Activity**
Here is the previous code
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
I wrote new application and followed advice.
import android.os.Bundle;
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
public class MainActivity extends ActionBarActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActionBar actionBar =getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
if I use ACtionBarActivity instead of Activity
I catch an error message on phone, when I try to run it.
Please tell me what I do wrong

I've got it worked after moving "Android Private Libraries" and "Android Dependencies" to the top of the list in Order and Export in my application project.
Also I dont have android-support-v7-appcompat in this list.
And in the android-support-v7-appcompat project I dont have support jars in the Order and Export list, but "Android Private Libraries" is checked.
Please, check also the links below:
Setting up ActionBarCompat support library in Eclipse
Implementing Action Bar using ActionBarCompat support library in Android
Make sure the support library is added to the project and exported. You can do so in Eclipse by viewing the properties of your project, clicking Java Build Path, then the Order and Export tab. Then make sure Android Private Libraries is checked.
Did you follow these steps: http://developer.android.com/tools/support-library/setup.html#
Had the exact same stack trace as you with Android Studio. I think it is caused by Android not being able to find a suitable theme for ActionBarActivity.
Anyway, this is how I solved it:
Add the following to your MainActivity in AndroidManifest.xml:
android:theme="#style/Theme.AppCompat.Light"
If it works now - great! If Android Studio cannot find the theme:
Copy the files
sdk/extras/android/support/v7/appcompat/res/values/themes.xml
sdk/extras/android/support/v7/appcompat/res/values/themes_base.xml
to the res/values/ folder in your project.

I have updated my cordova to resolve but still same error however a few days ago it was working fine and i have build some apps.
First download Cordova jar file from following link:
http://www.java2s.com/Code/JarDownload/cordova/cordova-1.8.1.jar.zip
after that extract the folder and put cordova-1.8.1 inside your libs folder of project in eclipse
And right click on your project--> properties and Select Android from left pane and scroll to bottom remove the cordova library if added.
then clean and build your project.
I have add into my project's libralies the andriod-support-v4.jar... but I am getting this error:

be sure to have android-support-v4.jar inside your folder /libs
and add this to your class:
import android.support.v4.app.NotificationCompat;
Decided to use Scandit SDK to get the barcode scanning feature in my app. Unfortunately, since I'm relatively new to Android development and Java in general I've run into a few issues that I can't seem to work out. The demo that Scandit provided doesn't give any errors(runs fine) but crashes when I try to start it up (pressing a button from one activity is meant to start it up). I've tried reading the logcat and googling a solution to the problems but I'm not getting the right solutions. Does anyone have an idea of what I'm doing wrong?

I came across this problem as well, my solution was to extract the library files and put them as their files in the lib folder
The library basically isn't being exported with it
EDIT
So I checked out my project, basically I did these things:
In the libs folder I have a new folder called armeabi and inside that I have libscanditsdk-android-3.3.1.so
Then in my build path I have also referenced the jar file that they provide:
<classpathentry exported="true" kind="lib" path="C:/GIT/Android/FwayScannerProject/FwayScanner/libs/scanditsdk-barcodepicker-android-3.3.1.jar"/>
I am writing a program that it needs Activity A to write data to a database, while Activity B read data from the database. I extended SQLiteOpenHelper Class as DatabaseHelper, and I get my database in Activity A in this way:
SQLiteOpenHelper dbHelper = new DatabaseHelper(this, "classtableDatabase", null, 1);
SQLiteDatabase db = dbHelper.getWritableDatabase();
It works in Activity well.
When I try to open the database created by Activity A in Activity B in same way, it failed and I get these error messages:

What should I do to fix this issue? Thank you for your help!
I had the same problem. You don't need to do anything just make static references to the database from the activities other than your MAIN activity.
I am using eclipse indigo with android ADT 20 but everytime it shows error that application stop unexpectedly.
Please any one have idea about how to use both of them with each other?
I also refer some google groupe which shows to update ecllipse and I also follow that but still not working. Thx in advance...

This issue occurs because the "lib" folder is renamed to "libs" now by Android People.
You need to create a libs folder instead of lib and then place your cordova.jar file there.
And as soon as we place our external jars to this "libs" folder then it will automatically be added to the build path of the application. Then run your application....
Let me know if this helps you...
You should try debugging your build. See here: http://www.droidnova.com/debugging-in-android-using-eclipse,541.html
I would recommend downloading the android sdk examples (ie native code examples) and running them to understand how android works. This will help you in setting up phonegap (which is just a webview in an android app with a JS-Native bridge).
To get the android sdk examples you can download them through the android "sdk manager"
