I want to load the image in ImageView after cropping the image and save it. But when it's resumes it gets crashed, but image is saving on selected location. I think the problem is in selectedImageUri. But I couldn't figure it out how to solve. Please someone help. Thanks in advance.
Code:
public class CatFragment extends Fragment implements OnClickListener{
private DBCreater dbCreate;
private static final int SELECT_PICTURE = 1;
private String selectedImagePath = "android.resource://com.example.abcd/" + R.drawable.pets;
private ImageView img;
//private Button imgBtn;
private Uri mCropImagedUri;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View gv = inflater.inflate(R.layout.new_pet, null);
Spinner sp = (Spinner) gv.findViewById(R.id.ETPetType);
// get reference
sp.setAdapter(new ArrayAdapter<String>(getActivity().getBaseContext(), android.R.layout.simple_spinner_dropdown_item, petType));
Button btnSubmit = (Button) gv.findViewById(R.id.ButtonNext);
btnSubmit.setOnClickListener(this);
img = (ImageView)gv.findViewById(R.id.ImageView01);
((Button) gv.findViewById(R.id.ETPetImg))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
try {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 0);
intent.putExtra("aspectY", 0);
intent.putExtra("outputX", 200);
intent.putExtra("outputY", 200);
intent.putExtra("return-data", false);
File f = createNewFile("CROP_");
try {
f.createNewFile();
} catch (IOException ex) {
Log.e("io", ex.getMessage());
}
mCropImagedUri = Uri.fromFile(f);
intent.putExtra(MediaStore.EXTRA_OUTPUT,
mCropImagedUri);
// start the activity - we handle returning in
// onActivityResult
startActivityForResult(intent, SELECT_PICTURE);
} catch (ActivityNotFoundException anfe) {
// display an error message
}
}
});
return gv;
}
private File createNewFile(String prefix){
if(prefix==null || "".equalsIgnoreCase(prefix)){
prefix="IMG_";
}
File newDirectory = new File(Environment.getExternalStorageDirectory()+"/test1/");
if(!newDirectory.exists()){
if(newDirectory.mkdir()){
Log.d(this.getClass().getName(), newDirectory.getAbsolutePath()+" directory created");
}
}
File file = new File(newDirectory,(prefix+System.currentTimeMillis()+".jpg"));
if(file.exists()){
//this wont be executed
file.delete();
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
return file;
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri); //To get image path
System.out.println("Image Path : " + selectedImagePath);
img.setImageURI(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
//Cursor cursor = managedQuery(uri, projection, null, null, null);
Cursor cursor = getActivity().getContentResolver().query(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
//access the database
dbCreate = new DBCreater(getActivity());
}
@Override
public void onClick(View v) {
displayNextAlert();
}

Edited:
I changed OnActivityResult() like this:
if(data!=null) {
Bitmap thePic = (Bitmap) data.getExtras().get("data");
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getActivity().getBaseContext());
String filename = preferences.getString("file_name", ""); // value to retrieve
String path = Environment.getExternalStorageDirectory()+"/PetSitter/Pet Images/" + filename;
img.setImageURI(Uri.parse(path.toString()));
} else {
// In createNewFile, make sure you already saved the filename (prefix+System.currentTimeMillis()+".jpg"), for example, to sharedpreferences then get the filename and apply in path
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getActivity().getBaseContext());
String filename = preferences.getString("file_name", ""); // value to retrieve
String path = Environment.getExternalStorageDirectory()+"/PetSitter/Pet Images/" + filename;
BitmapFactory.Options bfo = new BitmapFactory.Options();
bfo.inSampleSize = 1;
Bitmap bmp = BitmapFactory.decodeFile(path, bfo);
img.setImageBitmap(bmp);
}
It's seems to be working with image preview and everything. But what do thing? Is it a good practice to do? and how will be the memory usage by using like this?
