How to play flash file(in SDCard) on webView through HTML file present on sdcard ?

Create the flash.html file in sdcard which should be pointing towards flash file on sdcard......

<html>
<head>
<meta http-equiv="Content-Type" content="text/html" charset="UTF-8" />
</head>
<body>
<object width="215" height="140">
<param name="movie" value="choudanse7us.swf">
<embed src="file:///mnt/sdcard/choudanse7us.swf"
width="215" height="140">
</embed>
</object>
</body>
</html>

Create the following activity you will get the result............

public class FlashWebViewActivity extends Activity {
private WebView mWebView;

/** Called when the activity is first created. */
@Override
public void onCreate (Bundle savedInstanceState) {
super. onCreate (savedInstanceState);
setContentView(R.layout.main);

// html file with sample swf video in sdcard

//flash.html points to swf in sdcard

mWebView = (WebView)findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setPluginsEnabled(true);
mWebView.getSettings().setAllowFileAccess(true);

if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){
System.exit(4);
} else {
mWebView.loadUrl("file://" + Environment.getExternalStorageDirectory() + "/flash.html");
}
}
}

How to open the flash file present on sdcard in Android Webview?

Loading a image from sdcard in different ways?

Android - Load a image in a file (not drawable) as image in the layout

Sometimes, it is easier load a image from other directory (sdcard, for example)

than load a image from drawable because for this last case, the image should be

stored in the directory res/drawable first and packaged along with the apk files.

To load a image from a directory, it should be converted to the drawable first.

Here comes a piece of code which can help:

File file = new File ("/sdcard/1.jpg");
ImageView imageView = (ImageView) findViewById(R.id.icon);
imageView.setImageDrawable(Drawable.createFromPath(file.getAbsolutePath()));

Be warning that there is another method for ImageView called setImageURI(URI uri).

This method is used to load external files, it doesn't work with the type file.

For example, this code won't work:

File file = new File ("/sdcard/1.jpg");
ImageView imageView = (ImageView) findViewById(R.id.icon);
imageView.setImageURI(Uri.fromFile(file));

--------------------------------------------------------------------------------------------------------------------------------

The another way to use image from sdcard you can write the following code...........

imagePath="/sdcard"+"/"+filename;

try {

Bitmap bitmap = BitmapFactory.decodeFile(imagePath);

imageview.setImageBitmap(bitmap);

} catch (Exception e) {

e.printStackTrace();

File photos= new File("/sdcard/", "/Wockhardt/"+selectedFolderName+"/"+filename);

Bitmap b = decodeFile(photos);

imageview.setImageBitmap(b);

}

private Bitmap decodeFile(File f){
try {
//decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(new FileInputStream(f),null,o);

//Find the correct scale value. It should be the power of 2.
final int REQUIRED_SIZE=70;
int width_tmp=o.outWidth, height_tmp=o.outHeight;
int scale=1;
while(true){
if(width_tmp/2<REQUIRED_SIZE || height_tmp/2<REQUIRED_SIZE)
break;
width_tmp/=2;
height_tmp/=2;
scale++;
}

//decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize=scale;
return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
} catch (FileNotFoundException e) {}
return null;
}

Animate the layout's towards right and left i.e moving towards inside?

Create the file reverse_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<translate
android:duration="1000"
android:fromXDelta="-100%p"
android:toXDelta="0" />

<alpha
android:duration="1000"
android:fromAlpha="1.0"
android:toAlpha="1.0" />

</set>

and reverse_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<translate
android:duration="1000"
android:fromXDelta="100%p"
android:toXDelta="0" />

<alpha
android:duration="1000"
android:fromAlpha="1.0"
android:toAlpha="1.0" />

</set>

And just use it for your imageview and layout.....

img = (ImageView) findViewById(R.id.imageView1);
layout = (LinearLayout) findViewById(R.id.lin);

Animation rightAnimation = AnimationUtils.loadAnimation(this, R.anim.reverse_right);
Animation leftAnimation = AnimationUtils.loadAnimation(this, R.anim.reverse_left);

img.startAnimation(rightAnimation);
layout.startAnimation(leftAnimation);

How to write and read xml file on sdcard?

monthadapter.notifyDataSetChanged();

int setPostion=SalesPlannerArrayList.monthIdArray.indexOf(intentMonthId);
spn_monthList.setSelection(setPostion);

How to use Telephony of android device?

For Checking the Internet connection either WIFI or DataConnection---------->

public static boolean checkConnection(Context c)
{
ConnectivityManager mConnectivityManager = (ConnectivityManager) c
.getSystemService(Context.CONNECTIVITY_SERVICE);
TelephonyManager telephonyManager = (TelephonyManager) c
.getSystemService(Context.TELEPHONY_SERVICE);

if (mConnectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI)
.isConnected() || telephonyManager.getDataState() == TelephonyManager.DATA_CONNECTED)
return true;
else
return false;
// return true;
}

For retrieving IMEI or MACAddress----------->

IMEI_NO = ((TelephonyManager) getSystemService(TELEPHONY_SERVICE))
.getDeviceId();

if (IMEI_NO == null || IMEI_NO == "358673013795895") {
Log.d(TAG, "IMEI is null");
IMEI_NO = ((WifiManager) (getSystemService(WIFI_SERVICE)))
.getConnectionInfo().getMacAddress();
Log.d(TAG, "Mac address is:" + IMEI_NO);

}

Working with Date and Time?

For getting current time ------->

public static String getCurrentTimeStamp() {
SimpleDateFormat sdfDate = new SimpleDateFormat("yyyy-MM-dd");//dd/MM/yyyy
Date now = new Date();
String strDate = sdfDate.format(now);
return strDate;
}

For comparing date--------->

public static boolean dateComparator(String date1, String date2)throws ParseException {
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
Date pastDate = (Date) formatter.parse(date1);
Date futureDate = (Date) formatter.parse(date2);
if (pastDate.before(futureDate)||pastDate.equals(futureDate)) {
return true;

pattern = Pattern.compile(EMAIL_PATTERN);
Matcher matcher = pattern.matcher(email);
return matcher.matches();
}

How to change the default transition between activities?

In android the default transition between activities is to slide from left to right.But with custom animations we can change that.First create a folder inside the res/drawable folder called “anim”.Then create a file named “fade.xml” and copy this code into it.

<?xml version="1.0" encoding="utf-8"?>

<alpha xmlns:android="http://schemas.android.com/apk/res/android"

     android:interpolator="@android:anim/accelerate_interpolator"

      android:fromAlpha="0.0" android:toAlpha="1.0"

       android:duration="@android:integer/config_longAnimTime" />

create another file named “hold.xml” in the same place hold.xml.

<?xml version="1.0" encoding="utf-8"?>

<translate xmlns:android="http://schemas.android.com/apk/res/android"

       android:interpolator="@android:anim/accelerate_interpolator"

       android:fromXDelta="0" android:toXDelta="0"

 android:duration="@andro id:integer/config_longAnimTime" />

and just before starting the activity write down the following code

startActivity(new Intent(ActivityAnimation.this, SecondClass.class));

overridePendingTransition(R.anim.fade.xml,R.anim.hold.xml);
