So I've been working on a soundboard app for my kids. This is my first app so as you can imagine I very nearly have no idea what I'm doing (noob) so I'm apologizing in advance :-). I'm not sure where my problem is but my splash screen runs no problem but when it tries to load the next activity it force closes. i'm going to include my manifest the java file that is supposed to play the audio and the layout for the buttons which are clickable images. Thanks in advance! Also I would like to set it up where the buttons could play a random sound that relates to the image using soundpool but again with the noobness. I'm not really familiar at all with the errors but I'm seeing java.land.classcastexception: android.widget.imageview as the reason the mymenu activity isn't starting. Hope that helps.

Your Java code is expecting to find a Button object in your layout:
Button bSpongebob = (Button) findViewById(R.id.sbbutton);
But your layout declares that widget to be an ImageView:
<ImageView
android:id="#+id/sbbutton"
An ImageView isn't a Button, and when your Java code tries to force it to be a Button you get the java.lang.ClassCastException.
Two choices to fix:
1) Change your Java code to use ImageView.
2) Change your layout to declare a Button.
Either will accept the click listener you're trying to set. Don't forget you need to make this fix for both widgets in your app.

Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:"+num));
startActivity(intent);
}
}
I've tried rebuilding, cleaning the Project and research on Google, Stack, and Youtube without success.
Where i can also upload the Logcat?
Simply remove the <uses-permission android:name="android.permission.CALL_PHONE"/> from your MainActivity.xml file. I tested it on my side, and it fixed the problem.
Also, consider changing Intent.ACTION_CALL into Intent.ACTION_DIAL. The dial action doesn't require the permission you would remove.
I'm new in android and I just write a test app that should take the texts of the two buttons & change the text of them to each other in the new activity with intent.
but when I run the app and click the first button, it goes to second activity and in the second activity it just showing only the text of that button I just clicked on for both 2 buttons! actually, it should change the text of buttons to each other.(I mean the text of button 1 should display in button 2 and vice versa)
I check every question about the intent here, but my case is waired!!! because it seems everything is right! also, I check the code many times, I don't realize what's wrong!!!!
Thanks.

In your MainActivity, in changeText(),
buttonone=(Button) view;
buttontwo=(Button) view;
These two lines assign the same button view, to both the buttons.
Insted of this, I recommend doing the following in your onCreate() method after setContentView();
button1 = (Button) findViewById(R.id.button1);
button2 = (Button) findViewById(R.id.button2);
And remove those two lines in changeText().
I made an app it was working perfectly I also had a imageview with scrolling pictures.
All I did was add a button and after that when I run it the app will not show anything. just a plain white blank screen. I have a feeling it could be an intent issue but they seem to be fine with no errors.
Like I said the intents were working fine. I've checked every bit of my code but doesn't seem to load up my Main activity layout.(xml)
Unfortunately I didn't keep a backup . Also LogCat Doest not say anything whatsoever

You have a 1 behind the method onCreate. Is it just a copy-paste mistake ? If I remove it, you layout is shown
You have a typo on your onCreate method. It's written as onCreate1. If that's how it's written in the java file and not just a copt&paste error here, that may be your problem.
Check your android:layout_width and android:layout_height and make sure they are not cover other content is my guesss please post the xml file
I'm still very new to this so the solution is probably obvious.
Any way I'm trying to make the buttons in this app open new activities but when I run it, forcecloses. Does anyone know what's wrong? I was going to use something called list view but that didn't use the XML I made for the class.

fix your code by this
ImageButton mainMenu;
mainMenu = (ImageButton) findViewById(R.id.imagelogo);
UPDATE:
OK, I found the error. you forgot to set the OnClickListener for every Button or ImageButton
try this
majScales.setOnClickListener(this);
mainMenu.setOnClickListener(this);
For one thing you spelled the intent incorrectly.
Intent j = new Intent("com.exapmle.muscibynumbers.majorScales");
should be
Intent j = new Intent("com.example.musicbynumbers.majorScales");
For another, you have two applications defined.
Without the stack trace it's hard to know what else might be wrong.
I cant get my application to work, but theres no error message in the development.

//remove this life from your second activity
public class WebView extends Activity {
and register New in your manifest.xml
If I understand correctly, you're trying to open a new activity from an already running activity (Switching your page)? Try this.
Activity Main.java :
package tm.com
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class TmActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button butn = (Button) findViewById(R.id.button1);
butn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(TmActivity.this, New.class);
startActivityForResult(intent, 0);
}
});
}
}
Layout Main.xml :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button android:id="#+id/button1" android:text="name" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
</RelativeLayout>
In Application Manifest : *Modify the manifest in the application bracket to look like this.
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".TmActivity"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".New"></activity>
</application>
