Hi List
I am just trying to write a simple app that plays an MP3 when one clicks on
an Image Button.
I had the app starting up in the emulator fine but when I add the
MediaPlayer code I get the error:
"Sorry! The application EasyButton (process com.example.helloandroid) has
stopped unexpectedly. Please Try Again"
I assemble bits a pieces of code together so I might have done some thing
wrong, as I've never programmed in Java (well..anything) before.
My Java (I left in my first attempts, commented out):
EasyButton.java
package com.example.helloandroid;
import android.app.Activity;
import android.os.Bundle;
import android.media.MediaPlayer;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageButton;
//public class EasyButton extends Activity {
/** Called when the activity is first created. */
// @Override
// public void onCreate(Bundle savedInstanceState) {
// super.onCreate(savedInstanceState);
// setContentView(R.layout.main);
// final ImageButton button = (ImageButton)
findViewById(R.id.ImageButton);
// button.setOnClickListener(new OnClickListener() {
// public void onClick(View v) {
// // Perform action on clicks
// MediaPlayer mp = MediaPlayer.create(getBaseContext(),
R.raw.easy1);
// mp.start();
// }
// });
// }
//}
public class EasyButton extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
final MediaPlayer mplayer = MediaPlayer.create(EasyButton.this,
R.raw.easy1);
// PLAY button
ImageButton play = (ImageButton)
this.findViewById(R.id.ImageButton);
play.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// mp.prepare();
mplayer.start();
}
});
}
}
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android";
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
android:textSize="14sp"
android:typeface="sans"
/>
<ImageButton id="@+id/ImageButton"
android:src="@drawable/easybutton"
android:layout_gravity="center_horizontal|bottom"
android:layout_width="285px"
android:layout_height="372px"
/>
</LinearLayout>
The error console said everything is working ok. I'm using Eclipse 3.5.1.
with the Android Development Toolkit 0.9.3 (I just downloaded everything
today) on osX 10.5.6
These are just mis-mashed code snippets I've used to try and learn all of
this, so forgive me for any glaring mistakes. This is a great list to find
btw. Feel free to reply off list if this is a too big mess to deal with
here...
Cheers
James
