I cannot pass my search query which is sent from my MainActivity.java to my SearchResultsActivity.java, with a search widget as described on the official guide.
However, I don't want my search widget to be set on the actionbar.
I got no error. My only wish is to get my query displayed thanks to "Log.v".
But the official guide seems only to explain how to call the another activity when we got a search widget inside the actionbar, which isn't our case here.
How to retrieve the variable query in my MainActivity.java ?

public class MainActivity extends Activity {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#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;
}
}
SearchResultsActivity.java
package com.example.fidbacks_search;
import android.os.Bundle;
import android.app.Activity;

public class SearchResultsActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search_results);
Log.v("QUERY", "this isn t even being displayed when the search button is pressed");
// Get the intent, verify the action and get the query
Intent intent = getIntent();
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
Log.v("QUERY", query.toString());
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.search_results, menu);
return true;
}
}

I'm not sure exactly how you want it done, but I've used SearchView recently and to get what you want, I would simply do the following.
In your activity, add to onCreate something like:
searchView = (SearchView) findViewById(R.id.searchfield);
SearchManager searchManager = (SearchManager) getActivity().getSystemService(Context.SEARCH_SERVICE);
searchView.setQueryHint("Enter query here");
searchView.setOnQueryTextListener(this);
Then have your current activity implement SearchView.OnQueryTextListener's two methods; the one you are looking for is onQueryTextSubmit. Here, use the query that's passed to it and call your SearchResultsActivity.
Intent intent = new Intent(this, SearchResultsActivity.class);
intent.putExtra("query",query);
startActivity(intent);
Then have your SearchResultsActivity get the query in `onCreate':
query = getIntent().getStringExtra("query");
Then, use the query and do whatever you want with it.

I'm beginner in Android development and I'm trying to make Android app which will send SMS to another phone when button is clicked. I don't have Android phone so I'm trying to do that via emulators. I start one emulator which will be my "phone" which send SMS and another emulator which receives SMS.
Everything is compiled well and app starts, but when I click on button, I got message that "Unfortunately, app has stopped".
Here is the code which I have made.

and this is what the actionbar look like when I run the app: http://i.imgur.com/jADDz7b.png
The app doesn't show any errors, and the icon is put in the right way in the directories. so can anyone tell me what's the problem and how can I fix it?
The problem with #ZsoltBoldizsár's answer is that you are using ActionBarActivity. Change getActionBar() to getSupportActionBar()
Add the following code in onCreate(Bundle) after you call super.onCreate(Bundle):
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setIcon(R.drawable.ic_launcher);
Appcompat-v7 automatically disables setDisplayShowHomeEnabled so you must set it to true to show an icon.
You need to configure the actionbar. Read the documentation, but the line below might help you.
getActionBar().setHomeButtonEnabled(true);
getActionBar().setIcon(here comes your drawable id) (eg. R.drawable.ic_launcher)
Try with this:
ActionBar ab = getActionBar();
ab.setHomeButtonEnabled(true);
ab.setDisplayHomeAsUpEnabled(true);
ab.setDisplayShowTitleEnabled(false);
ab.setDisplayShowCustomEnabled(true);
ab.setTitle(Html.fromHtml("your text"));
ColorDrawable colorDrawable = new ColorDrawable(Color.parseColor(your_colorCode));
ab.show();
I am trying to make a call with the help of button, compiling time shows no errors but the application stops working as soon as i start the app, both on emulator and my android device. i have also set the permissions in the manifest file. but still :\

You can't instantiate abstract classes. Remove the 'abstract' from "public abstract class MainActivity", which will give you a different error telling you to implement the onClick method. Once you add that method that your app will launch.
I am a beginner in android development. I was trying a very simple code to get my location through the device gps and post it in a textView. I am not having any errors though when I start the application on the emulator it fails to start and I get this message "unfortunately test1 has stopped ".

Any help on making it work ??
Okay, this is really ticking me off. I ran it on both my emulator and on an android device. The code does NOT display "Helloworld, Android -mykong.com". I start the app, find it on the emulator, click on it, and it goes to interface of the app. However, it is just a blank screen! This error is not an issue of me finding the app, its not with the emulator or the android phone, the issue has to lie either in the code or in the way the code is structured/built. I know the the helloworld code is 100% correct because its from a reputable tutorial site. These are my three pairs of code. Please help, I am in desperate need!

You're not starting the HelloWorldjavaactivity.java activity. You need something like the following in your MainActivity:
Intent helloWorld = new Intent(getApplicationContext(), HelloWorldjavaactivity.class );
startActivity( helloWorld );
Of course, you need that code to be triggered by some even, a button press for example.
It would be easier to just eliminate the second activity (since your MainActivity isn't doing anything anyway) and put the code in your MainActivity instead. You'll also need to edit the layout for your MainActivity so that it includes the appropriate views.
