Basically my proble

Answer 1

Hey You Can just use the below Code to capture screen shoot in android and save it in ur SDCard and then you can use it later

// image naming and path  to include sd card  appending name you choose for file
String mPath = Environment.getExternalStorageDirectory().toString() + "/" + ACCUWX.IMAGE_APPEND;   

// create bitmap screen capture
Bitmap bitmap;
View v1 = mCurrentUrlMask.getRootView();
v1.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);

OutputStream fout = null;
imageFile = new File(mPath);

try {
    fout = new FileOutputStream(imageFile);
    bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fout);
    fout.flush();
    fout.close();

} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Then, when you need to access use something like this:

Uri uri = Uri.fromFile(new File(mPath));

My layout

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

tools:context=".MainActivity" >

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="70dp"
    android:text="Button" />

<ImageView

    android:src="@drawable/afor" />

    </RelativeLayout>

My Activity class

public class MainActivity extends Activity {

RelativeLayout rl; 
final int PIC_CROP = 1;
ImageView iv;
 File file;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    rl = (RelativeLayout) findViewById(R.id.rl);
     Button b= (Button) findViewById(R.id.button1); 
     iv= (ImageView) findViewById(R.id.imageView1);
     b.setOnClickListener(new OnClickListener()
     {

      @Override
      public void onClick(View v) {
          save();
     }
     });
}

   public void save()
   {
       AlertDialog.Builder editalert = new AlertDialog.Builder(MainActivity.this);
       editalert.setTitle("Please Enter the name with which you want to Save");
       final EditText input = new EditText(MainActivity.this);
       LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
               LinearLayout.LayoutParams.FILL_PARENT,
               LinearLayout.LayoutParams.FILL_PARENT);
       input.setLayoutParams(lp);
       editalert.setView(input);
       editalert.setPositiveButton("OK", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int whichButton) {
               rl.setDrawingCacheEnabled(true);
               String name= input.getText().toString();
               Bitmap bitmap =rl.getDrawingCache();
               String root = Environment.getExternalStorageDirectory().toString();
               File myDir = new File(root + "/MyDraw");    
               myDir.mkdirs();
               file = new File (myDir, name+".png");
               if (file.exists ()) file.delete ();         
               try

               {
                   file.createNewFile();
               }
                   FileOutputStream ostream = new FileOutputStream(file);
                   bitmap.compress(CompressFormat.PNG, 10, ostream);
                   ostream.close();
                   Uri uri = Uri.fromFile(new File(file.getAbsolutePath()));
                   performCrop(uri);                          
               } 
               catch (Exception e)

           }

       editalert.show(); 
   }


   private void performCrop(Uri picUri) {
    try {

   Intent cropIntent = new Intent("com.android.camera.action.CROP");
   // indicate image type and Uri
   cropIntent.setDataAndType(picUri, "image/*");
   // set crop properties
   cropIntent.putExtra("crop", "true");

   // indicate output X and Y
   cropIntent.putExtra("outputX", 128);
   cropIntent.putExtra("outputY", 128);
   // retrieve data on return
   cropIntent.putExtra("return-data", true);
   // start the activity - we handle returning in onActivityResult
   startActivityForResult(cropIntent, PIC_CROP);
 }
 // respond to users whose devices do not support the crop action
 catch (ActivityNotFoundException anfe) {
  // display an error message
  String errorMessage = "Whoops - your device doesn't support the crop action!";
  Toast toast = Toast.makeText(MainActivity.this, errorMessage, Toast.LENGTH_SHORT);
  toast.show();

 }




 @Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {

 if (requestCode == PIC_CROP) {

snap shots

My Layout snap shot

On button click prompting the user to enter a name to save

Image cropped and saved opened in gallery

Note: I have saved the cropped image in sdcard. The snap shots size varies. This worked for me on my device. I have posted the same. If anyone has a better idea pls edit the above post.
