Android - Intent makes my app crash

I am creating an app on Android, which involves an Activity and a service. One of the components of the service is meant to send a signal to the MainActivity, which will execute some specific code. The problem is, trying to send the intent makes the app crash.
Here is the code that sends the intent. Note that it resides in the inside of a doInBackground function of an AsyncTask object, which resides inside the said service:
#Override
protected String doInBackground(Socket... client) {
Intent received = new Intent();
received.setAction("com.mycompany.Messenger.MESSAGE_RECEIVED");
sendBroadcast(received);
}
Note that if I comment out sendBroadcast(received), the app does not crash.
Here is the handler of the Intent inside MainActivity (which has the name ChatBubbleActivity in my app):
public class MessageReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals(MESSAGE_RECEIVED)) {
String current_message = "Intent works!";
TextView textView = (TextView) findViewById(R.id.myText);
textView.setText(current_message);
}
}
}
And this is the declaration of the Receiver in manifest:
<receiver android:name=".ChatBubbleActivity$MessageReceiver">
<intent-filter>
<action android:name="com.mycompany.Messenger.MESSAGE_RECEIVED"/>
</intent-filter>
</receiver>
, inside the <activity> chunk.
What is it that I might be missing?
EDIT:New version of code based on answers, still crashing.

Do you want to start an activity or send a broadcast? I don't understand your code.
You are starting an activity from a background thread, that's not allowed.
In your AsyncTask, the method protected String doInBackground(Socket... client) is the only one that doesn't run in the UI thread.

When ever you want to start your Broadcast Receiver you don't call it as an acitivty
Your Method
Intent received = new Intent(ChatBubbleActivity.MESSAGE_RECEIVED);
received.putExtra("current", "Intent is working!!");
startActivity(received);
What it should be
Intent intent = new Intent();
intent.setAction("com.tutorialspoint.CUSTOM_INTENT");
sendBroadcast(intent);

Android emulator 4.0.3 Crashed when input text in a website through Webview

I've made a simple Android app that's trying to open a URL (any URL with input will do) on a click of a button.
The code I use is this :
btnTest = (Button)findViewById(R.id.btnTest);
btnTest.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
HelloActivity.this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com")));
}
});
The problem is that in Android Emulator running Platform 4.0.3, the emulator is crashed everytime I try to input text using soft keyboard into the web. This problem doesn't occur in Emulator running Platform 2.3.3. I've tried many sites and it behaves the same.
Btw, this is the logcat :

Can anyone tell me what's wrong here?

android.view.InflateException array

With your update you now got a stack over flow error : onSharedPreferenceChanged calls a method name preferenze that calls commit than triggers onSharedPreferenceChanged. After a certain number of "recursive" calls like this, you get out of heap space. Don't call commit from there.

The problem comes from the layout of MainActivity, not the preference xml file.
Check your fragments are properly declared with a android:name attribute.

Tak a look at
Could not find class 'android.content.ClipboardManager', referenced from method com.example.app.MainActivity.Copia
android.content.ClipboardManager is available from API lvl 11 - Android 3.0.
I think it can be connected with your problem.

Android - Settings.ACTION_DEVICE_INFO_SETTINGS crashes on android 4.1.1

I have an app where users can click on certain buttons in my app and it will launch specific settings page from Android to the user. I uses the android API from their website http://developer.android.com/reference/android/provider/Settings.html
Intent intent = new Intent(Settings.ACTION_SECURITY_SETTINGS);
currentContext.startActivity(intent);
Intent intent = new Intent(Settings.ACTION_DISPLAY_SETTINGS);
currentContext.startActivity(intent);
These are some of the settings pages that my app will open. So far I have no problem launching these two intents from my app. However, when I try to launch the "About tablet" page with the code below, the Settings process crashes.
Intent intent = new Intent(Settings.ACTION_DEVICE_INFO_SETTINGS);
currentContext.startActivity(intent);
It crashes on android 4.1.1 but it works fine on android 3.2. I'm still new to Android and I am at a lost on why it crashes. I'm new to StackOverflow as well. Hopefully I am able to get some answers here and nice to meet you all.
Here's my logcat:

Also, I tried to directly set the classname for this api...
Intent intent = new Intent();
intent.setClassName("com.android.settings", "com.android.settings.Settings$DeviceInfoSettingsActivity");
currentContext.startActivity(intent);
Same thing happens.It works for android 3.2 but doesn't work in 4.1.1. I've got a feeling that maybe I did not get the right class name for the 4.1.1 version. Does anyone know the direct class name to open the "About Tablet" page or whether is it possible to open that page programmatically?
Regards,
shuwen

android api doc say:
In some cases, a matching Activity may not exist, so ensure you safeguard against this.
so you should check this intent or catch this exception yourself.

ListView not getting displayed?

I have a activity which uses a listview element as follows
public class List1 extends Activity
{
Context context=this;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.listview);
try{
//DB
final SQLiteDatabase db;
db = openOrCreateDatabase(
"Secret.db"
, SQLiteDatabase.CREATE_IF_NECESSARY
, null
);
db.setVersion(1);
db.setLocale(Locale.getDefault());
db.setLockingEnabled(true);
Cursor cur = db.query("tbl_user",null,null,null,null,null,null);
//DB Over
ListView listView = (ListView) findViewById(R.id.mylist);
listView.setTextFilterEnabled(true);
final String[] values = new String[50];
int i=0;
while(cur.moveToNext())
{
values[i]=Integer.toString(cur.getInt(0))+":"+cur.getString(1)+":"+cur.getString(2);
i++;
}
cur.close();
ArrayAdapter<String> adapter = new ArrayAdapter<String>(context,R.layout.list_item,values);
listView.setAdapter(adapter);
listView.setVisibility(0);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
//public void onItemClick(ListView<?> listview, View view, int position,long id)
{
try
{
Intent i=new Intent(List1.this,Form1.class);
i.putExtra("uid","85");
startActivity(i);
finish();
}
catch(Exception e)
{
String insert2="insert into login values("+"\""+e.toString()+"\""+");";
db.execSQL(insert2);
}
}
});
db.close();
//required
}
catch(Exception e)
{
Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();}
}
}
This is my listview.xml file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView
android:id="#+id/mylist"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</ListView>
</RelativeLayout>
This is my list_item.xml file which has the required textview
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/tv1"
android:padding="10dp"
android:background="#drawable/textview1"
style="#style/textview_text"
android:textSize="16dp">
</TextView>
But the ListView is not working. I mean after coming to this activity the app is showing error showing "APP_NAME is stopped unexpectedly". The same code works for one or two times and then shows the above error continuously after that. May I kno why is it happening?

i think your adapter should know which textViewResourceId it should use.
So try this out: ArrayAdapter<String> adapter = new ArrayAdapter<String>(context,R.layout.list_item, R.id.tv1,values);

Change this to
<ListView
android:id="#+id/mylist"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
this
<ListView
android:id="#+id/mylist"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
And why do you need listView.setVisibility(0)?

final String[] values = new String[50];
int i=0;
while(cur.moveToNext())
{
values[i]=Integer.toString(cur.getInt(0))+":"+cur.getString(1)+":"+cur.getString(2);
i++;
}
cur.close();
Starting from the this spinet of code.
When the db.query returns you should rewind the cursor before starting to use it in the while loop. What if the query returns more the 50 results? Your app will crash with ArrayOutBoundException
