Activity doesn't start from NFC_TECH_DISCOVERED-intent filter

I am trying to read some information via NFC and created the intent-filter to do so, together with the xml that contains the required technologies. The intent-filter should start my ReadActivity, but it doesn't do so, when I put the card near my phone. NFC is activated, so this shouldn't be the problem. I really don't see the problem with my code, so it would be great if someone could take a look at it and maybe give me a hint in the right direction. Here is the code:

The AboutActivity and SettingsActivity don't contain anything yet, so I didn't include them in this post. I really don't know where the problem is though.

Restarting my phone and the NFC-setting solved the problem.

The recommended, and easier, way to sharing things with Facebook is using the Android Facebook SDK.
You can find documentation about how to integrate it with your app and how to share on the Facebook Developer site.
Note: Calling directly the sharing dialog, although it works, is unsupported and can break at any time, so it is definitely not recommended.

android search with suggestions

I want to make a search with suggestions.
after running the app and typing a string in my search box non of the following Logs Log.d("states","a onCreate"), Log.d("states",arg0.toString()), Log.d("states",query) or Log.d("states","searchactivity onCreate") execute.
What do I have to do do so the query() method in a.java or the onCreate() method in b.java are called?
Please dont send me to google developer documents its very confusing.

I think in your a-class you have to implement the getType()-method:
private UriMatcher uriMatcher;
#Override
public boolean onCreate() {
final String authority = "com.example.searchapp.searchsuggestion";
uriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
uriMatcher.addURI(authority, SearchManager.SUGGEST_URI_PATH_QUERY, SEARCH_SUGGEST);
uriMatcher.addURI(authority, SearchManager.SUGGEST_URI_PATH_QUERY + "/*", SEARCH_SUGGEST);
return true;
}
#Override
public String getType(Uri uri) {
switch (uriMatcher.match(uri)) {
case SEARCH_SUGGEST:
return SearchManager.SUGGEST_MIME_TYPE;
default:
throw new IllegalArgumentException("Unknown URL " + uri);
}
}

i can't redirect to next registration page when i click on to SIGN IN button

basically am a java developer but now am developing an android app.In my app i can't redirect to the next page when i click on to SIGN IN button and here is my code
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.widget.Button;
public class MainActivity extends ActionBarActivity implements View.OnClickListener {
Button log,sign;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
log = (Button) findViewById(R.id.login);
sign = (Button) findViewById(R.id.signup);
log.setOnClickListener(this);
sign.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId()) {
case R.id.login:
break;
case R.id.signup:
Intent open = new Intent("com.example.eblood.Register");
startActivity(open);
break;
}
}
}
}
Here is my next page java code
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class Register extends Activity{
Button backlog,regg;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.register);
backlog = (Button) findViewById(R.id.linktologin);
regg = (Button) findViewById(R.id.register);
backlog.setOnClickListener((OnClickListener) this);
}
public void onClick (View v)
{
switch(v.getId()) {
case R.id.register:
break;
case R.id.linktologin:
Intent in = new Intent("com.example.eblood.MainActivity");
startActivity(in);
break;
}
}
}
Here is my manifest code.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

<intent-filter>
<action android:name="android.intent.action.REGISTER" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
and the error am getting is android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.example.eblood.Register }
And here is my home.java
package com.example.eblood;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class home extends Activity {
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
Thread timer = new Thread(){
public void run(){
try{
sleep(2000);
} catch (InterruptedException e){
e.printStackTrace();
} finally {
Intent openMainActivity = new Intent("com.example.eblood.MAINACTIVITY");
startActivity(openMainActivity);
}
}
};
timer.start();}{
}
}

Try this..
If you use Intent open = new Intent("com.example.eblood.Register"); you will get ActivityNotFoundException change it as Intent open = new Intent(MainActivity.this,Register.class);
Change this
Intent open = new Intent("com.example.eblood.Register");
startActivity(open);
to
Intent open = new Intent(MainActivity.this,Register.class);
startActivity(open);
also
change this
Intent in = new Intent("com.example.eblood.MainActivity");
startActivity(in);
to
Intent in = new Intent(Register.this,MainActivity.class);
startActivity(in);
EDIT
Change this.
Intent openMainActivity = new Intent("com.example.eblood.MAINACTIVITY");
startActivity(openMainActivity);
to
Intent openMainActivity = new Intent(home.this,MainActivity.class);
startActivity(openMainActivity);

App crashes while testing on phone after package renaming attempt

I was attempting to rename/refactor my package name for my app. It didn't work out well, so I deleted and imported the older working version.
But after I did this, when I tried to test on my phone the app keeps crashing (It works fine before). It works fine on the emulator though. How can I fix this?
EDITED:
The logcat:
Can anyone please help? How do I fix this? Thank you.
