Calling the function "startActivity" in other class and file doesn't work

I want call the function startActivity in two ways:

First (It works):

        public class HelloWorld extends Activity
{
        public boolean onOptionsItemSelected(MenuItem item) {
            if(item.getItemId() == 1){
                startActivity(new Intent(Intent.ACTION_DIAL,Uri.parse("tel:660718109")));
            }
            else {
                return super.onOptionsItemSelected(item);
            }
            开发者_StackOverflow社区return true;
}

Second: in HelloActivity.java

    public class HelloWorld extends Activity {
    public boolean onOptionsItemSelected(MenuItem item) {
        if(item.getItemId() == 1){
            IntentsUtils.tryOneOfThese(this);
        }
        else {
            return super.onOptionsItemSelected(item);
        }
        return true;
}

in IntentsUtils.java

public class IntentsUtils
{
   public static void tryOneOfThese(Activity activity)
   {
       IntentsUtils.call(activity);
   }
   public static void call(Activity activity)
   {
      Intent intent = new Intent(Intent.ACTION_CALL);
      intent.setData(Uri.parse("tel:5555555555"));
      Log.v("MyLogs", "It's works!");
      activity.startActivity(intent);
   }
}

The second way doesn't work - I have a error in aplication when I clicked on position in menu. I know function "call" in IntentsUtils work because analise logs in "LogCat"

This is my logs from LogCat: android.permission.CALL_PHONE

android.permission.CALL_PHONE> 10-27 16:10:56.702:

Thanks in advance, Michael

The problem is your action.

ACTION_CALL is restricted to specific apps (I think system apps only). The reason you get your logcat message is because you log it before you try to start the activity. A permission error is going to occur because the system will not allow your app to directly call a phone number. You can dial it, but the user has to press call.

This is a security issue, if they let any application start making phone calls to numbers.

From the Android SDK Documetation:

Note: there will be restrictions on which applications can initiate a call; most applications should use the ACTION_DIAL.

edit
after looking at your last edit, with the logcat. I can say 100% that your issue is with using ACTION_CALL.

Long story short, you do not have permission to use ACTION_CALL, you have to use ACTION_DIAL.

Try setting the FLAG_ACTIVITY_NEW_TASK as given in

http://developer.android.com/reference/android/content/Context.html#startActivity(android.content.Intent)

you may have to set like this:

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

I havent tried this. But worth to give a try
