Viewing logs and exceptions in Android

We moved. Please visit this link for this post.

 

 

 

I found that there is no logcat console in android plugins for NetBeans and IDEA 8.

But when you develop application you need to see exceptions or see simple log.

I am going to show how easy is to see all these things in system console.

At first you should have installed Android SDK.

At second type in your console:

adb logcat

Note: emulator instance should be working.

Context menu in Android is similar to context menu in any others OS.

Adding alphabetic shortcut to the menu item in Android

We moved. Please visit this link for this post.

 

 

 

There is a way to add shortcut to your menu item.

I am going to show how it can be done.

@Override
public boolean onCreateOptionsMenu(Menu menu) {
	menu.add(0, NEW_MENU_ITEM, 0, "New").setAlphabeticShortcut('N');
...
	return super.onCreateOptionsMenu(menu);
}

As you see it is very easy.
How you can test it? Run your code with this snippet, click Menu button and after click “N”.

Adding icon to the menu item in Android

We moved. Please visit this link for this post.

 

 

 

There is a good practice to add icons to the menu items.

I am going to show code snippet which add icon to the menu item:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
   menu.add(0, ADD_MENU_ITEM, 0, "Add").setIcon(android.R.drawable.ic_menu_add);
   return super.onCreateOptionsMenu(menu);
}

This code adds icon add to the menu item ADD_MENU_ITEM.

As you see this is simple operation.

Getting formatted string from strings.xml in Android

We moved. Please visit this link for this post.

 

 

 

I found way to get formatted string from strings.xml.

I am going to show how I did it. Please refer to getString method.

strings.xml

<string name="text">My name is %s. I work at FaYna Soft Labs %d months.</string>

Activity

getResources().getString(R.string.text, "Oleg Mazurashu", 7)

Example:

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

/**
 * Activity which shows how to use formatted string from strings.xml
 *
 * @author FaYna Soft Labs
 */
public class Main extends Activity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
      TextView tv = (TextView) findViewById(R.id.textId);
      tv.setText(getResources().getString(R.string.text, "Oleg Mazurashu", 7));
  }
}

I like this approach.
