I think this is a problem related to the emulator and not the physical device.
I used this code and I got a bitmap:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
captureButton = (Button)findViewById(R.id.capture);
captureButton.setOnClickListener(listener);
imageView = (ImageView)findViewById(R.id.image);
destination = new File(Environment.getExternalStorageDirectory(),"image.jpg");
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == REQUEST_IMAGE && resultCode == Activity.RESULT_OK) {
//Bitmap userImage = (Bitmap)data.getExtras().get("data");
try {
FileInputStream in = new FileInputStream(destination);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 10; //Downsample 10x
Bitmap userImage = BitmapFactory.decodeStream(in, null, options);
imageView.setImageBitmap(userImage);
} catch (Exception e) {
e.printStackTrace();
}
}
}
private View.OnClickListener listener = new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
//Add extra to save full-image somewhere
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(destination));
Toast.makeText(JMABarcodeScannerActivity.this, Uri.fromFile(destination).toString(), Toast.LENGTH_SHORT).show();
startActivityForResult(intent, REQUEST_IMAGE);
}
};
}
