I am trying to include thquinn's DraggableGridView into my project. I followed all the instructions given there for getting started including these steps for adding a jar to my project. (DraggableGridView.jar is showing as a referenced library.)
It compiles correctly, but when run my project I get the following error in Logcat:

Here's my import:
import com.animoto.android.*;
In my activity I have:
DraggableGridView dgv = ((DraggableGridView) findViewById(R.id.dgv));
ImageView iv = new ImageView(getApplicationContext());
iv.setImageDrawable(new BitmapDrawable(Images[index]));
dgv.addView(iv);
The last line is where the build error is. What am I missing?
First of all, as Eclipse can resolve your dependency but Dalvik cannot, it seems that the library wasn't bundled with your application. The typical cause of this is adding your library as a normal Java dependency into /lib, whereas building for Android expects the jar in /libs. See also this question.
Secondly, looking at the source, it appears that your import is not specified correctly. DraggableGridView's qualified name is com.animoto.android.views.DraggableGridView.
Your activity should declare the import as:
import com.animoto.android.views.DraggableGridView;

This morning I updated various SDK components from Eclipse. I think it was
- Android SDK or Platform tools
- Google APIs 17 update
- Android Support Library
- Google Play Services
Now, my apps won't deploy. They build ok (eventually, after an hour of reconfiguring and rebuilding) but now when I deploy to the device, I get the following:

Bear in mind that this project, and others, have been happily running for months, so this isn't just some daft error like the activity missing from the manifest file.
I'm really wishing I hadn't bothered with the update now... any ideas welcome!
I faced this issue couple of days before.
Right click your project, Go to properties->Java Build path->Order and Export
Check Android Private Library->Click Ok
Clean the project and run it.it will work.
sdk\extras\android\support\v4 inside there is a jar file android-support-v4.jar add this to the external jars
My android Project on playing piano music, so i added jfugue.jar to my project.
my java code is:
line no:29 Player player=new Player();
line no:30 player.play("C D E F G A B");
the above code is written in button onclick listener. when i am clicking on that button i got RunTimeEexception, as below:

I never used jFugue, but it looks like your problem is that Android doesn't implement javax.sound.midi. So you need to find/develop an implementation of this package.
Here are some options discussed: A simple free MIDI implementation in Java besides javax.sound.midi: Are there any?
Where have you inserted your jar file.?
Also please check if you have build the jar file.
I am writing a project that uses LruCache, which is included in the android-support-v4.jar compat library. When running on devices with JB, the code works fine, but when I run it on my Droid X with GB, the app dies with the following errors:

Utility.java:49 looks like this:
mCache = new LruCache<String, Bitmap>( mCacheSize ) // <-- line 49 --
{
#Override
protected int sizeOf( String key, Bitmap bitmap )
{
return bitmap.getByteCount();
}
};
So everywhere I referenced LruCache or its methods causes an error. The first thing that comes to mind is that android-support-v4.jar was somehow left out of the APK file, but that doesn't look like the case. I've placed the jar file under libs/, and checking classes.dex.d after running ant debug, I see that it has added the following line:
/home/paul/workspace/blah/libs/android-support-v4.jar \
My second thought was that maybe LruCache isn't in android-support-v4, but looking at the source I see that the following source file is in there, and that it has the methods I am trying to use:
/home/paul/bin/android-sdk/extras/android/support/v4/src/java/android/support/v4/util/LruCache.java
So why isn't it found?
The classes in the support library use a different namespace.
You need to import:
import android.support.v4.util.LruCache;
or alternatively you can copy & compile LruCache.java directly into your app.
I have created a very simple Android app just to work with functionality. Within the app I would like to call a web service client to retrieve and display some data. I think I have succesfully imported and referenced the jar file (i.e. library). It appears to be instantiating the class successfully but when that class is referencing another class within the jar/library it throws a class not found error. Any ideas??? Anything else I can provide to help answer???
Here is my code:
package mhcs.android.ehd;
import mhcs.services.client.EHD.EHDClient;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class GetTicketDescription extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
EHDClient client = new EHDClient();
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String title = getString(R.string.title);
setTitle(title); // done so that we can change the default title
//get handles to editText and button widgets
final EditText eText = (EditText) findViewById(R.id.editText1);
final Button button = (Button) findViewById(R.id.button1);
eText.setText(client.getTicketDescription("MMLZ-8LVRMK"));
button.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View v) {
//get the String entered into the editText widget
CharSequence editText = eText.getText();
//display the toast
Toast.makeText(GetTicketDescription.this, editText, Toast.LENGTH_LONG).show();
}
});
}
}
Here is the error:

Find Properties -> Java Build Path -> Order and Export
Change Android Dependencies order
Try to create a new folder called libs under your project and put the .jar file there...
I had the same problem, I tried to mark the Android Private Libraries under Order and Export and it didn't work for me. Then I noticed that my libs folder wasn't referenced under the Java Build Path. So I just added it to Libraries and it worked.
Go to
Project> Build Path >Configure Build Path
Check the Libraries you wanted and hit ok

The code from com.ww is inside a jar that I used on the other builds.
I am getting this too now and am able to get around it by removing all external jars from the project. You can add them back in after it's been cleaned. I'm assuming you have access to the original project source code...
Rightclick on project, go to Java Build Path, and remove all external jars other than your Android libs. Then clean.
Got this error after updating to the Android Platform Tools preview 15 rc5 and Android Tools 21 rc5, plus running the "check for updates..." in eclipse.
LogCat error
java.lang.NoClassDefFoundError: com.someapplicationlibrary.lib.R$layout

Errors running builder 'Android Pre Compiler' on project 'someapplicationlibrary'.

Tried to revert to the stabel Android Tools... but ending up with even more errors.
My solution was to load the workspace in a eclipse version that was not updated with the "check for updates..." in the eclipse Help menu.
Then it compiled correct, and the application worked again, hope this helps:)
