protected void onActivityResult(int requestCode, int resultCode, Intent data) {

if (resultCode == Activity.RESULT_OK) {

(everything else)
}
Copy-Methode:
private void copyImageToInternalStorage(File sourcefile) {
String timeStamp = new SimpleDateFormat("ddMMyyyy_HHmmss").format(new Date());
File folder = getExternalFilesDir("ImageDatabase");
File file = new File(folder, "IMG_"+timeStamp+".jpg");
if(!sourcefile.exists()){
return;
}
FileChannel source = null;
FileChannel dest = null;
try {

dest = new FileOutputStream(file).getChannel();
if(source != null && dest != null){
dest.transferFrom(source,0,source.size());
}
if(source != null){
source.close();
}
if(dest != null){
dest.close();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
GetPath-Methode:
public String getPath(Uri uri) {
String[] projection = {MediaStore.Images.Media.DATA};
// Cursor cursor=managedQuery(uri, projection, null, null, null);
@SuppressWarnings("deprecation")
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
Aber das gibt mir NullPointerException. Was muss geändert werden?
