PermissionUtils cannot be resolved

I'm working on an app that will allow users to report potholes and other roadside issues easily. My specific issue is in the map I included; in the report activity that will allow users to pinpoint where the problem is by using google maps and some markers. To do this I'm basically copying code word for word from the google maps api and my problem is that the permission utils object isn't being inherited from google play services. I had put this code down for a while (out of frustration) so i dont exactly remember what the other issues were but i remember getting the code around permission utils to not give me an error was kind of a bitch. Anyway so please help ;_;. I apologize for how i space my code, it is just visually easier for me, the first block is the message activity, the second is my manifest. please let me know if I should post anything else.

The startactivity(intent) method causes an error. Why?

I want after a click on the OK button the MenuActivity to be shown. I have already searched on the Internet to find an answer and tried everything. I haave the activity declared in the AndroidManifest and I also tried to use Intent(this, MenuActivity.class) and also the one with the action inside but it doesn't work.

Unfortunately I can't show you my Logcat because it doesn't work on my computer. (I always have to export the APK to test the App).
P.S. I am working with Android Studio 1.0.1
...Please HELP ME !

To open a new activity you simply have to call it like this inside the onClick method.
Intent intent = new Intent(v.getContext(), MenuActivity.class);
startActivity(intent);
So your onClick method will look like this.
#Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), MenuActivity.class);
startActivity(intent);
}
Hope this helps.

Is because you say MainActivity.this, but you aren't in the MainActivity context.
You could make a reference of your current context in onCreate() and save it in a field:
private Context context;
#Override
protected void onCreate(Bundle savedInstanceState) {
context = this;
//rest of your code here
}
and use it as:
Intent intent = new Intent(context, MenuActivity.class);
//Something else
context.startActivity(intent);

Go to your manifest file, you will for your MainActivity manifest:
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
Just copy them and paste them for your MenuActivity.
I had the same same problem than you and it worked for me, but I don't know why.
Good luck!

first make sure your AndroidManifest.xml file contain declaration of all Activities in your app, like
<activity android:name=".MenuActivity"/>
then you create new intent and start it where you need to start the second Activity
Intent intent = new Intent(v.getContext(), MenuActivity.class);
startActivity(intent);

Mike M is perfectly correct your intent filter should contain action for sms, i.e., "android.provider.Telephony.SMS_RECEIVED" not something else.
Secondly you require an activity to launch am broadcast receiver from android 3.1 for security issues.

Fetching number of Contacts from android contact app

I want to fetch number of contacts from contact list. I follow the links of Stack Overflow and make a project. But it is not working.
The MainActivity.java is as follows:
package com.example.shiza.countcontacts;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;
import android.database.Cursor;
import android.provider.ContactsContract;
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void GetTheContact()
{
Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
int count = cursor.getCount();
CharSequence text = "Total number is" + count;
// int count = 1;
Toast.makeText(this,text, Toast.LENGTH_LONG).show();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
I am novice in Android. Please help me.
The manifest.xml is:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.shiza.countcontacts" >
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.READ_CONTACTS" />
</manifest>

First step, you have to declare the permission on AndroidManifest
<uses-permission android:name="android.permission.READ_CONTACTS" />
Second, you have to access the contact list from you phone, and only after you may get the size of the list and the data from each contact.
This link will provide a example made by Google.
