What steps will reproduce the problem?
1. Make a canvas, make brick containing the Dragged-event
2. Convert
3. Look in src

What is the expected output? 

    private void Canvas1_Dragged( float startX, float startY, float prevX, float prevY, float currentX, float currentY, boolean draggedSprite )
    {
...



    public void dispatchEvent( Object component, String id, String eventName, Object[] args )
    {
...
        if( eventName.equals( "Dragged" ) && component.equals( cnvDrawingCanvas ))
            cnvDrawingCanvas_Dragged( (Float)args[0], (Float)args[1], (Float)args[2], (Float)args[3], (Float)args[4], (Float)args[5], (Boolean)args[6] );



What do you see instead?


    private void Canvas1_Dragged()
    {
... (noncopmpi)
}


    public void dispatchEvent( Object component, String componentName, String eventName, Object[] params )
    {
...
        if( component.equals( Canvas1 ) && eventName.equals( "Dragged" ) )
        {
            Canvas1_Dragged();
        }




What version of the product are you using? On what operating system?

trunk from SVN



Of course, this can be fixed manually. Other people might use the above manual 
fix as a workaround untill the code generation has been fixed.

Decompiling an appinventor APK I can see that this is missing:



        <activity android:name="com.google.appinventor.components.runtime.ListPickerActivity" android:screenOrientation="behind" android:configChanges="keyboardHidden|orientation" />
        <activity android:name="com.google.appinventor.components.runtime.WebViewActivity" android:screenOrientation="behind" android:configChanges="keyboardHidden|orientation">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
            </intent-filter>
        </activity>

    </application>
    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.INTERNET" />

What steps will reproduce the problem?
1. Download project source which was build with latest App Inventor version
2. Do everything like the tutorial said
3. Fail

What is the expected output? What do you see instead?
I expected to see no errors and java files in the output map.

What version of the product are you using? On what operating system?

I converted some code using list pickers and bluetooth.

Most of the code seems actually to be OK!

But I stumbled into this showstopper:


The generated code was:
    ListPicker1.Elements( BluetoothClient1.AddressesAndNames() );

But ListPicker1.Elements( ) expects an YailList, and 
BluetoothClient1.AddressesAndNames() returns a List<String>.

So I changed to

    List<String> l = BluetoothClient1.AddressesAndNames();
    YailList yl = YailList.makeList(l);
    ListPicker1.Elements( yl );


which seems to accepted in the editor. However, when I compile I get:

Compiling 3 source files to 
/home/j/android/AppInventor/appinventor-til-java/xxx/bin/classes
/home/j/android/AppInventor/appinventor-til-java/xxx/src/org/robot1/Screen3.java
:78: cannot access gnu.lists.Pair
class file for gnu.lists.Pair not found
    YailList yl = YailList.makeList(l);
1 error

Looking at the libSimpleAndroidRuntime.jar I can see that it depends on the GNU 
classes, but they are not included.

What steps will reproduce the problem?
1. C:\users\myname\desktop\app_inventor_java_conversion> java -jar 
AppInventorToJava.jar
2. INPUT:  C:\Users\myname\Desktop\install checklist source code.zip
   OUTPUT:  C:\Users\emmertw\workspace\installChecklist2.zip
3. Click Convert

What is the expected output? What do you see instead?
I started a new project in the Eclipse program and after starting a project, 
made a copy and zipped the contents. I then downloaded my app inventor code 
from google docs where google put them when app inventor shut down. I then made 
a copy of that file and zipped it. I then followed the steps listed above with 
the App Inventor zip as the input, and the Eclipse zip as the output. I had 
expected to see some sort of output that tells me it's working. I get the 
message  Error Generating Manifest:  java.lang.NullPointerException in the 
command prompt when I hit convert. Then, it corrupts the output zip file.


What version of the product are you using? On what operating system?
build 67

Please provide any additional information below.
That is all I can tell you, I suck as actual Java Programming, but actually 
managed to eek out an awesome application in App-inventor. I figured I could 
just use this to translate it (to some degree) and use that as a launch-pad to 
start actual Java Programming.

I've attached the Google Supplied app-inventor code and my zipped project from 
Eclipse (un corrupted) so you can see.

What steps will reproduce the problem?
1. Choose the App Inventor downloaded zip file (Robotar.zip)as input.
2. Choose a directory for the output (RoboTar)
3. Click Convert.

What is the expected output? What do you see instead?
I was expecting the source to be created in the RoboTar director.

What version of the product are you using? On what operating system?
build-72.jar

Please provide any additional information below.

What steps will reproduce the problem?
1. run appinventor2java.jar
2. select zip input (my project) & zip ouput(i suppose, the zip with source 
translated)
3. click in convert

What is the expected output? What do you see instead?
i expected the zip with the new source. 
nothing

What version of the product are you using? On what operating system?
build 67 & win7 x64

Please provide any additional information below.

Your code should be changed from using the project name as key for the screens 
to using the screen name

Change from:


    private void loadSourceFile( String path, InputStream inputStream ) throws IOException
    {
        projectName = getFolder( path );
        AppInventorScreen screen = screens.get( projectName );

        if( screen == null )
            screen = new AppInventorScreen( projectName );

        if( path.endsWith( ".blk" ))
            screen.loadBlocksFile( inputStream );
        else if( path.endsWith( ".scm" ))
            screen.loadComponentFile( inputStream );
        else if( path.endsWith( ".yail" ))
            screen.loadInterfaceFile( inputStream );

        screens.put( projectName, screen );
    }



to:



    private String getScreenName( String path )
    {
        int lastSlash = path.lastIndexOf( '/' );
                path = path.substring(lastSlash);
        int lastDot = path.lastIndexOf( '.' );
                return path.substring(0, lastDot);
    }



    private void loadSourceFile( String path, InputStream inputStream ) throws IOException
    {
        projectName = getFolder( path );
        String screenName = getScreenName( path );
        AppInventorScreen screen = screens.get( screenName );

        if( screen == null )
            screen = new AppInventorScreen( projectName );

        if( path.endsWith( ".blk" ))
            screen.loadBlocksFile( inputStream );
        else if( path.endsWith( ".scm" ))
            screen.loadComponentFile( inputStream );
        else if( path.endsWith( ".yail" ))
            screen.loadInterfaceFile( inputStream );

        screens.put( screenName, screen );
    }
