AppWidget layout not showing, "widget failed to load"

Good day guys, I wonder why when i drag the widget out to my home screen, it only display "widget failed to load" instead of my widget layout. I need help.

Widget.java

package com.fyp.atms;

import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
import android.content.Intent;
import android.widget.RemoteViews;
import android.widget.Toast;

public class Widget extends AppWidgetProvider{

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager,
            int[] appWidgetIds) {
        // TODO Auto-generated method stub
        super.onUpdate(context, appWidgetManager, appWidgetIds);

    }

    @Override
    public void onDeleted(Context context, int[] appWidgetIds) {
        // TODO Auto-generated method stub
        super.onDeleted(context, appWidgetIds);
        Toast.makeText(context, "Widget deleted!", Toast.LENGTH_SHORT).show();
    }

}

widget.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <Spinner
        android:id="@+id/spinner1"
        android:layout_width="114dp"
        android:layout_height="40dp" />

    <LinearLayout

            android:layout_width="114dp"
            android:layout_height="40dp" />

        </TableLayout>
        <Button
            android:id="@+id/wid_trans"
            android:layout_width="100dp"
            android:layout_height="40dp"
            android:layout_weight="50"
            android:text="Translate" />
    </LinearLayout>

    <TextView
        android:id="@+id/wid_Translated"
        android:layout_width="130dp"
        android:layout_height="35dp"
        android:ems="10" />

</LinearLayout>

You can't use a Spinner or an EditText in a Widget. That's because every Widget layout must be based on RemoteViews. Following every layout that is supported:

Layout classes

FrameLayout
LinearLayout
RelativeLayout
GridLayout

Widget classes

AnalogClock
Button
Chronometer
ImageButton
ImageView
ProgressBar
TextView
ViewFlipper
ListView
GridView
StackView
AdapterViewFlipper

Read more about it in the Docs.

The problem is your layout contains an EditText which is not supported by widgets on Android.

For a complete list of views you may use see: http://developer.android.com/guide/topics/appwidgets/
