I'm trying to add a photo from galery to a ImageView
but I get this error:
java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1, result=-1, data=Intent { dat=content://media/external/images/media/1 }} to activity {hotMetter.pack/hotMetter.pack.GetPhoto}: java.lang.NullPointerException
This is my code:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
}
Bitmap bitmap=null;
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);
tv.setText(selectedImagePath);
img.setImageURI(selectedImageUri);
}
}
public String getPath(Uri uri)
{
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if (cursor == null) return null;
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String s=cursor.getString(column_index);
cursor.close();
return s;
}
I get the selectedImagePath="mnt/sdcard/DCIM/myimage"
but on img.setImageURI(selectedImageUri);
i get the error.
I've also used a Bitmap
and tried to set the image from SetImageBitmap
but i get the same error.

Advice please.Thanks!
Simple pass Intent
first:
Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
And you will get picture path on your onActivityResult
:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
