Can't display my activity from navigation drawer

I have a navigation drawer with some options (Home, Bluetooth, Alarm, Tips). I linked an activity to Bluetooth and Alarm but I got some problems with Home.
When I run the application I have a splash screen which is connected to the Home.java, in this activity I can click on my drawer and select the others alarm.java anche bluetooth.java but, when I link an activity to home, using the same method, my app stops working.
Thank you so much!

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);

android activity stack- back navigation

I am developing an app which has a home screen consisting of list view(Home Activity).User clicks on list item and new activity is started named as Topic.This activity also consist of list view. Home is set as parent activity for Topic.
Now in Topic class i am again calling Topic class using intent.
So a user clicks on a list item in Home activity,which opens a new Topic activity.User again clicks on list item ,and another new activity Topic is created,so we are at rd level. My app is working fine till here, but as Parent for Topic is Home,so as soon as i press back or up button,irrespective of where i am in my app,it is always the Home class which opens.
How to handle this so that all user can traverse back to each activity.

Please help.Thanks in advance

Comment finish() inside the listitem click in topic class. it will solve your problem.

What you could do is, do not set Home as the parent of Topic.
This way when user presses back, the previous activity that was open will be shown to the user.

Menu won't show in navigation bar

im trying to add a (+) icon on right of navigation bar in android, and then launch a new intent when clicked, but i can't seem to make it work, it's showing me the left icon to open/close the drawer, but the right icon is nowhere to be found.

Change following line in onCreateOptionsMenu
return super.onCreateOptionsMenu(menu);
to
return true;

The id of your menu item is the same name as the string (action_new_list). I'd try changing that to see if there's a collision.
2. Add a titleCondensed attribute, as that's all that will show in your Options Menu.
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/action_new_list"
android:icon="#drawable/action_search"
android:title="#string/action_new_list"
android:titleCondensed="#string/new_string"
android:showAsAction="ifRoom|withText" />
</menu>
