and I'm controlling this option with a check box here is it

StartUP.setOnClickListener(new OnClickListener() {


        //Start of on boot
      @Override
      public void onClick(View v) {
                //is StartUP checked?
        if (StartUP.isChecked()) {

             PackageManager pm  = MainActivity.this.getPackageManager();
                ComponentName componentName = new ComponentName(MainActivity.this, StartUP.class);
                pm.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
                                PackageManager.DONT_KILL_APP);
                Toast.makeText(getApplicationContext(), "activated", Toast.LENGTH_SHORT).show();


        }else{

              PackageManager pm  = MainActivity.this.getPackageManager();
                ComponentName componentName = new ComponentName(MainActivity.this, StartUP.class);
                pm.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
                                PackageManager.DONT_KILL_APP);
                Toast.makeText(getApplicationContext(), "Deactivated", Toast.LENGTH_SHORT).show();
        }

      }
    });

and the broadcast reviver class here

  public class StartUP extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
           // This method is called when the BroadcastReceiver is receiving

           // Start Service On Boot Start Up
           Intent service = new Intent(context, ServiceSocial.class);
           context.startService(service);



    }
}

also my manifest I have this :

<receiver android:name="StartUP" android:enabled="false">
        <intent-filter >                
            <action android:name="android.intent.action.BOOT_COMPLETED"/>                
        </intent-filter>
    </receiver>

You need to find out what is null on line 156 of ServiceSocial.java, and either find out why it's null if it's not supposed to be, or accommodate the case where it is null if null is acceptable there.

Then read this: How to read and understand the java stack trace?

line 156 is an if condition, not null at all – mohamedrashad Apr 11 '14 at 21:24
The stack trace doesn't lie. – Brodo Fraggins Apr 11 '14 at 23:37
