Cannot Resolve symbol 'R' in Android Studio :"manifest merger failed with multiple errors, see logs"

I'm a beginner and I use Android Studio. A problem keeps on bothers me.

It keeps on showing "Cannot Resolve symbol 'R' " everywhere with R.XXX.XXX

I've tried:


1.checking my xml files, including manifest

2.checking SDK whether Build Tools is installed

3.clean project

4.rebuild project

5.sync project with Gradle files

6.every way I could find on Internet


while rebuilding project the message shows "manifest merger failed with multiple errors, see logs"

I briefly paste a part of my activity here:

public class Clock_mainpage extends Activity {

private Button button_start;

private static final int START_LOCATION = 1;

private Item item;


private void findButton()
{

button_start = (Button) findViewById(R.id.start);

}

private Button.OnClickListener startclock = new Button.OnClickListener()
{
@Override
public void onClick(View view)
{
Intent intentMap = new Intent(Clock_mainpage.this, MapsActivity.class);

intentMap.putExtra("lat", item.getLatitude());
intentMap.putExtra("lng",item.getLongitude());
intentMap.putExtra("title",item.getTitle());
intentMap.putExtra("datetime",item.getLocaleDatetime());

startActivityForResult(intentMap, START_LOCATION);
finish();

}
};


Seems it appears to be something wrong in my Manifest.xml
I post it below:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

You didn't past the most important think in such problem with R a imports. Problem is known and simple. For sure you had problem with some resources. R class was not generated. You get info from IDE that R can not be found and IDE propose you quick fix: import R class.

But because your R was not generated at that point and IDE has only android.R avaliable. IDE impot android.R

Please double check imports. In import you should have:

yourpackage.R
