Unable to use checkbox in eclipse with android adt plugin

I'm a newbie android app developer, beginner really. I've tried creating a checkbox on the xml layout on eclipse IDE, for some reason when I run app, it just crashes.
It says resource not found. Following is the logcat:

Can someone help me fix this.

I'm assuming you've updated to v23.2 of the support library. I did the same and I had the very same issue. Here's how i fixed it, hope it works for you as well.
1) Update to the latest version of Gradle (1.5.0 as of posting this) from the Android Tools repo: ensure you have this in your Build.gradle file (the one outside all modules).
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'
}
2) If you're using Android Studio 1.4, stop it from generating .png files from vector drawables at run time and use the support libraries, support-vector-drawable and animated-vector-drawable, to do the same instead. Add this to your Build gradle INSIDE your 'app' module
android {
defaultConfig {
generatedDensities = []
}
aaptOptions {
additionalParameters "--no-version-vectors"
}
}
Also refer http://android-developers.blogspot.in/2016/02/android-support-library-232.html

Upgrading Android Design Support Library (com.android.support:design) from 23.2.0 to 23.2.1 may help solve the problem.

Upgrade support library to last version (23).
This exception it cause by android.content.res.Resources$NotFoundException: File res/drawable/abc_btn_check_material.xml, this is an element from last version of support library
I think you must migrate to AndroidStudio if you are beginner on Android, Eclipse stopped having support google in December 2015
PD: sorry for my english

please help me. thanks

You are giving the file
/data/data/com.example.esporttv/libs/.lock
as a streaming source. You should always check if the file exists using file.exists() function.
Can you also post the lines where you initializee the player?

If you are using Android Studio, here is the solution, original article here:
Create a folder called “lib” (must be exactly this name)
Create subfolders in lib with desired architecture name such as
“armeabi-v7a”, “armeabi” etc.
Put all your *.so file in the just created folder. Now your folder structure should be like this:
lib\armeabi-v7a
...
lib\armeabi
Zip the lib folder into a file, e.g. abc.zip;
Rename this abc.zip –> abc.jar
Copy this abc.jar to your project subfolder, anywhere should do, but
I would typically put it in the app\libs\abc.jar
In the build.gradle, add below line.
That is it!
dependencies {
compile files(‘libs/abc.jar’)
…
}

ArrrayAdapter requires resourceID to be a text view

The goal of this project of mine is to update a spinner dynamically with user input. Unfortunately I'm losing this battle. Logcat keeps throwing the resource ID error at me, HOWEVER, I don't understand why it's only thrown on button press, wouldn't it be thrown after onCreate, if that's where the problem is?
Eclipse (via ctrl + space) tells me the to specify the Resource ID of the layout CONTAINING the TextView. Which I also don't even understand why I would need a textview, if I'm just handling an array and a spinner. AndroidDevelopment site also says the same. I'm just confused.So, my question is, what does this error mean, and what am I doing wrong?
I BELIEVE this is the line in question:
list = new ArrayAdapter<String>(this,R.layout.settings,items);
This is the .java
package com.example.thepicker;
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.Spinner;
public class Settings extends Activity implements OnClickListener{
EditText getit;
ImageButton giveit;
Spinner thelist;
ArrayList<String> items;
ArrayAdapter<String> list;
String transit;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.settings);
items = new ArrayList<String>();
list = new ArrayAdapter<String>(this,R.layout.settings,items);
getit = (EditText) findViewById(R.id.getit);
giveit = (ImageButton) findViewById(R.id.giveit);
thelist = (Spinner) findViewById(R.id.thelist);
thelist.setAdapter(list);
giveit.setOnClickListener(this);
}
#Override
public void onClick(View v) {
String transit = getit.getText().toString();
items.add(transit);
list.insert(transit, 0);
list.notifyDataSetChanged();
}
}
This is the logcat

I suspect the problem to be in the line:
list = new ArrayAdapter<String>(this,R.layout.settings,items);
please try to replace R.layout.settings with android.R.layout.simple_spinner_item
second parameter is a resource identifier, that should point to the TextView with id="#android/text1"(that is what Android expects)
android.R.layout.simple_spinner_item corresponds to predefined TextView layout, that is located in the SDK folder(try to look into the folder, where SDK is installed: <SDK_FOLDER>/platforms/<select_any_platform_by_api_level>/data/res/layout/simple_spinner_item.xml, there are some pretty nice predefined layouts, that should help you understand the logic)

Since ArrayAdapter requires a TextView, as the exception says, you have two options:
Change R.layout.settings to android.R.layout.simple_spinner_item.
Create your own Adapter subclass which inflates your custom layout.

Is there a way to see a complete stack trace from android?

When I get an uncaught exception in my app and the trace prints to the logcat, is there anyway to make the entire trace print out? At the end of the trace it always has something like "...10 more".
Example:
03-11 16:25:53.572: ERROR/AndroidRuntime(3297): Caused by: java.lang.ClassNotFoundException: net.notify.notifymdm.listeners.PackageInstallerReceiver in loader dalvik.system.PathClassLoader[/data/app/net.notify.notifymdm-2.apk]

03-11 16:25:53.572: ERROR/AndroidRuntime(3297): ... 10 more

Usually the "...N more" represents n more lines of the same error, anyway.

What jumps out at me 1st is that map activities should extend MapActivity

Your activity must extend MapActivity and you are missing the Maps Api key in your MapView definition. You can get it here.
