intent.putExtra("camerasensortype", 2);
intent.putExtra("autofocus", true);
intent.putExtra("fullScreen", false);
intent.putExtra("showActionIcons", false);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(tempFile));
startActivityForResult(intent, PHOTO_CARMERA);
}
protected void startPick(DialogInterface dialog) {
dialog.dismiss();
Intent intent = new Intent(Intent.ACTION_PICK, null);
intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
"image/*");
startActivityForResult(intent, PHOTO_PICK);
}
private void startPhotoZoom(Uri uri, int size) {
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setDataAndType(uri, "image/*");
intent.putExtra("crop", true);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("outputX", size);
intent.putExtra("outputY", size);

private void setPicToView(Intent data) {
Bundle bundle = data.getExtras();
if (null != bundle) {
final Bitmap bmp = bundle.getParcelable("data");
image.setImageBitmap(bmp);

saveCropPic(bmp);
Log.i("MainActivity", tempFile.getAbsolutePath());
}
}
private void saveCropPic(Bitmap bmp) {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
FileOutputStream fis = null;
bmp.compress(Bitmap.CompressFormat.PNG, 100, baos);
try {
