Back button on Action Bar crashing app android

Synposis: I have 3 activity (LoginActivity, MainActivity and EditProfileActivity). After Facebook login in my LoginActivity I srart the MainActivity. (Till this point the app is working perfectly correct with no error). I have a NavigationDrawer for my navigations, When I click on Edit Profile link from the NavigationDrawer it starts the EditProfileActivity.
Problem: When I click on the LeftArrow in the Top blue bar, the app crashes.
Please see the images:

You have to define your activities parent in the manifest file like this
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="fully qualified activity name" />
Make sure that you keep this meta data of your activity containing back button. Other wise its just like you are not telling you back button where to go !!
You have to add these two lines in your MainActivity.java file:
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
Add this in your onOptionsItemSelected(MenuItem item) method:
if (id==android.R.id.home)
{
NavUtils.navigateUpFromSameTask(this);
}

In your toolbar.xml set an imageview. Do like this i your toolbar.xml
<ImageView
android:id="#+id/tv_header_title2"
android:layout_width="25dp"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:src="#drawable/backbutton"
android:layout_marginLeft="15dp"/>
In MainActivity
ImageView img= (ImageView) findViewById(R.id.tv_header_title2);
and
img.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
}
});

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);

In my case, I changed the targeted sdk to 19 and also find that you didn't define the uses-sdk in the manifest...!
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />

Try changing the uses-permission syntax like this:
<uses-permission android:name="android.permission.SEND_SMS"/>

import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
Button sendstring;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sendstring = (Button) findViewById(R.id.sendstring);
sendstring.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {

}
});
}

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.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();
if (id == R.id.action_settings) {

This is my ApplicationB MainActivty:
package com.example.applicationb;
import java.util.ArrayList;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;
public class MainActivity extends Activity {
TextView text_recieve;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
text_recieve = (TextView) findViewById(R.id.text_recieve);
// Get intent, action and MIME type
Intent intent = getIntent();
String action = intent.getAction();
String type = intent.getType();
if (Intent.ACTION_SEND.equals(action) && type != null) {
if ("text/plain".equals(type)) {
handleSendText(intent); // Handle text being sent
} else if (type.startsWith("image/")) {
handleSendImage(intent); // Handle single image being sent
}
} else if (Intent.ACTION_SEND_MULTIPLE.equals(action) && type != null) {
if (type.startsWith("image/")) {
handleSendMultipleImages(intent); // Handle multiple images being sent
}
} else {
// Handle other intents, such as being started from the home screen
}
}
void handleSendText(Intent intent) {
String sharedText = intent.getStringExtra(Intent.EXTRA_TEXT);
if (sharedText != null) {
// Update UI to reflect text being shared
text_recieve.setText(sharedText);
}
}
void handleSendImage(Intent intent) {
Uri imageUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);
if (imageUri != null) {
// Update UI to reflect image being shared
}
}
void handleSendMultipleImages(Intent intent) {
ArrayList<Uri> imageUris = intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);
if (imageUris != null) {
// Update UI to reflect multiple images being shared
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.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();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);

In the intent to start your other app you have to mention its package name like:
intent.setClassName("com.farhan.appb",
"com.farhan.appb.MainActivity");

I have solved my Problem:
my MainActivity from ApplicationA:
package com.example.applicationa;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends Activity {
Button sendstring;
EditText edit_text;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// startService(new Intent(MainActivity.this, MyService.class));
edit_text = (EditText) findViewById(R.id.edit_text);
sendstring = (Button) findViewById(R.id.sendstring);
sendstring.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
startService(new Intent(MainActivity.this, MyService.class));
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.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();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
This is my Background Service class:
package com.example.applicationa;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;
public class MyService extends Service {
private static final String TAG = "MyService";
MediaPlayer player;
String et_name;
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
// Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
// et_name = getIntent().getStringExtra("dealer_id");
/*
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "Hi Farhan Shah,Welcome to AppB");
sendIntent.setType("text/plain");
// startActivity(sendIntent);
startActivity(Intent.createChooser(sendIntent, getResources().getText(R.string.send_to)));*/
/*player = MediaPlayer.create(this, R.raw.braincandy);
player.setLooping(false);*/ // Set looping
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
// TODO Auto-generated method stub
if(intent != null){
et_name = intent.getStringExtra("et_name");
}
return super.onStartCommand(intent, flags, startId);
}
#Override
public void onDestroy() {
Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
Log.d(TAG, "onDestroy");
// player.stop();
}
#Override
public void onStart(Intent intent, int startid) {
Toast.makeText(this, "" + et_name, Toast.LENGTH_LONG).show();
Log.d(TAG, "onStart");
Intent sendIntent = new Intent();
sendIntent.setClassName("com.example.applicationb",
"com.example.applicationb.MainActivity");
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
sendIntent.putExtra(Intent.EXTRA_TEXT, "Hi Farhan Shah,Welcome to AppB");
sendIntent.setType("text/plain");
startActivity(sendIntent);
// player.start();
}
