Some Useful Common functions :-)

Change data on UI Thread [runOnUiThread(Runnable)]

(new Thread(new Runnable()
{
@Override
public void run()
{
while (!Thread.interrupted())
try
{
Thread.sleep(1000);
runOnUiThread(new Runnable() // start actions in UI thread
{
@Override
public void run()
{
displayData(); // this action have to be in UI thread
}
});
}
catch (InterruptedException e)
{
}
}
})).start();

Check whether Device is mobile or Tab :-

public static String finddevice(Context ctx){
String userAgent = new WebView(ctx).getSettings().getUserAgentString();
if(userAgent.contains("Mobile")){
return "mobile";
}else{
return "tab";

}
}

Set Device Orientation Pragmatically :-

public static void landscapeview(Context ctx){
((Activity) ctx).setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}

Set Device Keyboard on hidden state :-

public static void hiddenkeybord(Context ctx){
((Activity) ctx).getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
}

Udust Device Keyboard for easy type :-

// Inside activity tag on particular activity declaration - Manifest file

android:windowSoftInputMode="adjustPan"

Handling back button pragmatically :-

public public void onBackPressed() {

// TODO Auto-generated method stub
// super.onBackPressed();
AlertDialog dialog = new AlertDialog.Builder(Current_Activity.this)

.setTitle("Warning")
.setIcon(R.drawable.i_img)
.setMessage("Exit Application?")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
System.exit(0);
// Current_Activity.this.finish();
}
})
.setNegativeButton("No",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
}
}).create();
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
WindowManager.LayoutParams WMLP = dialog.getWindow().getAttributes();
WMLP.gravity = Gravity.CENTER_VERTICAL | Gravity.LEFT;
dialog.getWindow().setAttributes(WMLP);
dialog.show();
}

Check Available Memory :-

public boolean checkMemory() {
Log.i("getExternalStorageState "
+ Environment.getExternalStorageState(), "Checking availability");
StatFs stats;
double bytes;
double megaBytes;
if (Environment.getExternalStorageState().equals(
Environment.MEDIA_MOUNTED)) {
stats = new StatFs(Environment.getExternalStorageDirectory()
.getPath());
bytes = (double) stats.getAvailableBlocks()
* (double) stats.getBlockSize();
megaBytes = bytes / 1048576;
Log.i("getExternalStorageState MOUNTED", megaBytes + "MB available");
if (megaBytes < 40) {
AlertDialog ad = new AlertDialog.Builder(Current_Activity.this)
.setTitle("Attention!")
.setMessage(
"There is not enough memory in SD Card, please free some space.")
.setIcon(R.drawable.app_icon)
.setCancelable(true)
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0,
int arg1) {
memoryFlag = true;
}
}).create();
ad.requestWindowFeature(Window.FEATURE_NO_TITLE);
WindowManager.LayoutParams WMLP = ad.getWindow()
.getAttributes();
WMLP.gravity = Gravity.CENTER_VERTICAL | Gravity.RIGHT;
ad.getWindow().setAttributes(WMLP);
ad.show();
} else {
memoryFlag = true;
}
} else {
stats = new StatFs(Environment.getDataDirectory().getPath());
bytes = (double) stats.getAvailableBlocks()
* (double) stats.getBlockSize();
megaBytes = bytes / 1048576;
Log.i("getDataDirectory", megaBytes + "MB available");
if (megaBytes < 40) {
AlertDialog ad = new AlertDialog.Builder(Current_Activity.this)
.setTitle("Attention!")
.setMessage(
"There is not enough space in Internal memory, please free some space.")
.setIcon(R.drawable.app_icon)
.setCancelable(true)
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0,
int arg1) {
memoryFlag = false;
}
}).create();
ad.requestWindowFeature(Window.FEATURE_NO_TITLE);
WindowManager.LayoutParams WMLP = ad.getWindow()
.getAttributes();
WMLP.gravity = Gravity.CENTER_VERTICAL | Gravity.RIGHT;
ad.getWindow().setAttributes(WMLP);
ad.show();
} else {
memoryFlag = true;
}
}
return memoryFlag;
}

Animated layouts In Android :-)

Pre-Requirements
=============
1 . Create one folder inside res folder - "anim"
2. Add animated-xml files in to anim folder.

Changes in Activity
=============

1. class has to extend Activity as well as implements AnimationListener

Eg : public class Activity_Classname extends Activity implements AnimationListener

2.Declare Animation variable .

Eg : Animation slide_up ;

3.Assign Action into that variable .

Eg : slide_up=AnimationUtils.loadAnimation(getApplicationContext(),
R.anim.slide_down);
slide_up.setAnimationListener(this);

4.call this animation variable where ever u want

Eg : layout_name.startAnimation(slide_up);

Simple steps to create action bar icons with its events.
