Question

I am using camera Intent to open the camera:

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);

Now I am trying to get the path of the captured photo but its throwing error:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST) {
Uri uri = data.getData();
String imagePath = getRealPathFromURI(uri);
}
}

private String getRealPathFromURI(Uri contentUri) {
    String[] proj = { MediaStore.Images.Media.DATA };
// import android.support.v4.content.CursorLoader; i import this for CursorLoader
    CursorLoader loader = new CursorLoader(getApplicationContext(), contentUri, proj, null, null, null);
    Cursor cursor = loader.loadInBackground();
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}

Its throwing Error which is:

FATAL EXCEPTION: main
java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=100,     result=-1, data=Intent { act=inline-data (has extras) }} to activity  {com.xxx.xxx.BbmpActivity}: java.lang.NullPointerException

I think because of this line it throwing error:

CursorLoader loader = new CursorLoader(getApplicationContext(), contentUri, proj, null, null, null);

here what i need to give instead of getApplicationContext()
I also try this but till it throwing error:

CursorLoader loader = new CursorLoader(this, contentUri, proj, null, null, null);

when I start this application then it throw one error which is:

Could not find class 'android.content.CursorLoader', referenced from method com.xxx.xxx.BbmpActivity.getRealPathFromURI

Answer 1

Instead of Uri uri = data.getData();write like..

if(data!=null){
  if (requestCode == CAMERA_REQUEST) {  
           Uri uri =  data.getExtras().get("data"); 
         //or...
     Bitmap bitmapPicture = (Bitmap) data.getExtras().get("data"); 
     // other code
}
}

It will work fine. main thing is data.getExtras().get("data");
