I want to develop application that sends image/txt or any file from one android device to another none android device using Bluetooth.
Please anyone can give help or source code for that?
Here is the code from which you can send file via bluetooth from android device to any device.
btnOk.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
txtContent = (EditText)findViewById(R.id.txtContent);
imageView = (ImageView)findViewById(R.id.imageView);
linearLayout = (LinearLayout)findViewById(R.id.linearLayout);
viewToBeConverted = (TextView) findViewById(R.id.hello);
linearLayout.setDrawingCacheEnabled(true);
//Toast.makeText(MainActivity.this, file.toString(), Toast.LENGTH_LONG).show();
try
{
if(file.exists())
{
file.delete();
}
out = new FileOutputStream(file);
}
catch (Exception e)
{
Toast.makeText(MainActivity.this, e.getMessage(), Toast.LENGTH_LONG).show();
}
viewToBeConverted.setText(txtContent.getText().toString());
viewToBeConverted.setDrawingCacheEnabled(true);
// Toast.makeText(MainActivity.this, " " + viewToBeConverted.getDrawingCache(), Toast.LENGTH_LONG).show();
txtContent.setText("");
Bitmap viewBitmap = linearLayout.getDrawingCache();
linearLayout.setVisibility(1);
imageView.setImageBitmap(viewBitmap);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
viewBitmap.compress(Bitmap.CompressFormat.PNG, 100, baos); //bm is the bitmap object
byte[] b = baos.toByteArray();
try
{
out.write(b);
out.flush();
out.close();
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("image/png");
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file) );
startActivity(intent);
}
catch (Exception e)
{
Toast.makeText(MainActivity.this, " " + e.getMessage(), Toast.LENGTH_LONG).show();
}
}
});
Enjoy. :)
