Result code 0 for Camera Intent

问题:

Code:-

  Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);                                   
        try{
               imageUri = Uri.fromFile(File.createTempFile("image", ".jpg"));
           }catch (Exception ex){
               ex.printStackTrace();
          }

   intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, imageUri);
    startActivityForResult(intent, REQUEST_CAMERA);

I am using all permissions related to this in android manifest file... that above intent is working fine in mot g3 turbo and many more devices but in the case of only nexus 5 the resultCode is coming 0.. why?

With the guidance of CommonsWare Sir, I resolved my problem by doing the following changes...

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
destination = Environment.getExternalStorageDirectory().getPath() + "/image.jpg";
outputUri= Uri.fromFile(new File(destination));
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputUri);
if (Build.VERSION.SDK_INT>=Build.VERSION_CODES.LOLLIPOP) {
  intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
} else {
  List<ResolveInfo> resInfoList = getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
  for (ResolveInfo resolveInfo : resInfoList) {
      String packageName = resolveInfo.activityInfo.packageName;
      grantUriPermission(packageName, outputUri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
  }
}         

startActivityForResult(intent, REQUEST_CAMERA);
