The next problem as shown in the picture, it requires user interference to press ok if the user like it . here in this step I need to take just one picture once is taken should go back to main activity. and store the picture in Image View .

the last request or ideas guys how to send this pict to the email interference from the user . here is the Code -----------------------------------

public class MainActivity extends Activity {
    ImageView viewpict;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        viewpict=(ImageView) findViewById(R.id.pict_result);
        Button btn= (Button)findViewById(R.id.camera);

            @Override
            public void onClick(View arg0) {
                Intent intent = new Intent (android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            //  Intent intent = new Intent (getApplicationContext(),MainActivity2.class);

                //startActivity(intent);
                startActivityForResult(intent,0);

            }

     });


    }

protected void onActivityResult( int requestCode, int resultCode,Intent data)
{
    if (requestCode==0)
    {
        Bitmap theimage = (Bitmap) data.getExtras().get("data");
        viewpict.setImageBitmap(theimage);
    }

}

}

Answer 1

First you have to save that bitmap to sdcard then you can attach that image to email.

to save bitmap to sdcard is

FileOutputStream out = null;
 try {
out = new FileOutputStream(filename);
bmp.compress(Bitmap.CompressFormat.PNG, 100, out); // bmp is your Bitmap    instance
// PNG is a lossless format, the compression factor (100) is ignored
} catch (Exception e) {
e.printStackTrace();
} 
   try {
    if (out != null) {
        out.close();
    }
} catch (IOException e) {
    e.printStackTrace();

}

and then you can read that image and attach to email

for that have a look at this link How to attach Bitmap to email android

Answer 2

To send the image through mail, you can use this:

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
emailIntent.setType("application/image");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, "Test Email"); 
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Test Subject"); 
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "From My App"); 
emailIntent.putExtra(Intent.EXTRA_STREAM,Uri.parse("file:///mnt/sdcard/Myimage.jpeg"));
startActivity(Intent.createChooser(emailIntent, "Send mail..."));

Answer 3

In your onActivityResult method you should open a new Activity to view the image preview, one that has an xml with an imageview, ok and cancel buttons.

Send your bitmap to this activity and put it in its imageview - the preview activity can have a static bitmap ImagePreview property.

When pressing ok, you should save image to sdcard, and then send email, as described by @Moubeen.

Answer 4

you can convert a bitmap into PNG in external storage.

File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
File imageFile = new File(path, getCurrentTime()+ ".png");
FileOutputStream fileOutPutStream = new FileOutputStream(imageFile);
bitmap.compress(Bitmap.CompressFormat.PNG, 80, fileOutPutStream);

fileOutPutStream.flush();
fileOutPutStream.close();  

Then, you will get URI through url.Parse(). which you can share .

Uri.parse("file://" + imageFile.getAbsolutePath());  


Intent intent= new Intent(android.content.Intent.ACTION_SEND); 
intent.setType("application/image");
intent.putExtra(android.content.Intent.EXTRA_EMAIL, "Email"); 
intent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Your Subject"); 
intent.putExtra(android.content.Intent.EXTRA_TEXT, "Text"); 
intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + imageFile.getAbsolutePath()));
startActivity(Intent.createChooser(intent, "mail sending"));
