It's the usual activity. The problem is in onCreateOptionMenu. When I click the menu button nothing is done. I don't see where the problem is.
I also try to comment all code without menu but It's still don't work.
It is either a very strange problem or I don't see some simple things..

Help if you see a solution.
You've misspelled method name - it should be onCreateOptionsMenu(), not onCreateOptionMenu().
It's preferable to use #Override annotation to avoid such mistakes:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
This way it will give you compile time error if you misspell method name or use wrong parameters.
Change your onCreateOptionsMenu to:
//Menu
#Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(Menu.NONE, INFO, Menu.NONE, "О программе").setIcon(
R.drawable.info);
menu.add(Menu.NONE, BLOCK, Menu.NONE, "Блокировать").setIcon(
R.drawable.block);
menu.add(Menu.NONE, CLOSE, Menu.NONE, "Выход").setIcon(R.drawable.exit);
return true;
}
It should work now!
try to add
#Override to public boolean onCreateOptionMenu
And do you try to use MenuInflater and inflate menu from xml?

Everything looks fine in your code.
Make sure you have active internet connection in your mobile where you are trying to run this application.
If you are using Internet, then don't forget to add this to your AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET"/>

I'm working on my first app. Got everything set up and working correctly, except displaying a random quote from a text file. Clicking the button shows weird characters (diamonds, question marks, etc) and not the actual text except for the placeholder off and on.

I am looking to write multiple strings to file for storage using android. Is it possible to add all strings to a toString using .getText and if so how. I am looking to create some edit text fields and take the information contained in these fields and write them to a file before then reading the file in a different activity.

Problem is the string which writes to outputstreamswriter has correct value but in try/catch block within onclick() method of dialogue box outputstreamwriter is not working. My file name is default.txt i'm sure file name has nothing to do with the problem. outputstreamwriter does not change the content of file whatsoever i've tried bufferwriter or fileoutputstream but nothing seems to work. Kindly help i'm losing my mind from days now!

In your onClick you read a file from assets and save it to internal memory.
On the next click the same happens.
You should read the file from internal memory too if you want to check if the write succeeded.
