I'm a beginner and completely lost trying to fix an Inflate Exception. I have a clue that the Inflate Exception is caused by the serialization of a beans class, however, how this all works together is beyond my understanding.
The logcat looks as following, note that this happens once I open a dialog containing a ListView which in turn is based on the beans class I was talking about:
01-31 12:59:22.628 27314-27314/com... I/AppCompatDelegate: The Activity's LayoutInflater already has a Factory installed so we can not install AppCompat's

First of all, I have the aforementioned beans class Media.java:
public class Media implements Parcelable {
private String duration;
private String title;
private URL url;
private String contentType;
private Bitmap thumbnail;
private String resolution;
private String bandwidth;
public Media(Parcel parcel) throws MalformedURLException {
this.duration = parcel.readString();
this.title = parcel.readString();
this.url = new URL(parcel.readString());
this.contentType = parcel.readString();
this.thumbnail = parcel.readParcelable(Bitmap.class.getClassLoader());
this.resolution = parcel.readString();
this.bandwidth = parcel.readString();
}
/* ... */
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(duration);
dest.writeString(title);
dest.writeString(url.toString());
dest.writeString(contentType);
dest.writeValue(thumbnail);
dest.writeString(resolution);
dest.writeString(bandwidth);
}
public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
public Media createFromParcel(Parcel in) {
try {
return new Media(in);
} catch (MalformedURLException e) {
e.printStackTrace();
return null;
}
}
public Media[] newArray(int size) {
return new Media[size];
}
};
}
The Inflate exception occurs in this ArrayAdapter:
public class VideoPickerArrayAdapter extends ArrayAdapter<Media> {
public VideoPickerArrayAdapter(Context context, int resource, List<Media> items) {
super(context, resource, items);
}
private class ViewHolder {
ImageView imageView;
TextView txtResolution;
TextView txtDuration;
Button btShare;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
final Media media = getItem(position);
LayoutInflater mInflater = (LayoutInflater) getContext().getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = mInflater.inflate(R.layout.video_picker_list_item, null);
holder = new ViewHolder();
holder.imageView = (ImageView) convertView.findViewById(R.id.itemicon);
holder.txtResolution = (TextView) convertView.findViewById(R.id.itemresolution);
holder.txtDuration = (TextView) convertView.findViewById(R.id.itemduration);
holder.btShare = (Button) convertView.findViewById(R.id.ShareButton);
convertView.setTag(holder);
} else
holder = (ViewHolder) convertView.getTag();
holder.txtResolution.setText(media.getResolution() + "p@" + media.getBandwidth() + " Mb/s");
holder.txtDuration.setText(media.getDurationString());
holder.imageView.setImageBitmap(media.getThumbnail());
/* Share button */
holder.btShare.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(media.getUrl().toString()));
shareIntent.setType("video/mp4");
getContext().startActivity(Intent.createChooser(shareIntent, "Share to"));
}
});
return convertView;
}
The XML layout of the listview (video_picker_list_item.xml) looks like this, note that the line 38 mentioned in the stacktrace is the Share button.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

</RelativeLayout>
Previous to making the Media class Parcelable, I would not get the Inflate exception everytime I opened the dialog, but it would still occur seemingly random like every second time I added some Media to the list and then opened the dialog. I know that the inflate exception never occured once I was able to display the list, even if I closed and opened the dialog again, unless I changed it's content. However, the App would still crash 3 seconds after I pressed the share button with an exception like 'can't marshal Media@fdsg94934'. I tried to fix this error by making the Media Parcelable, but now I'm facing the Inflate exception everytime I try to open the dialog.
I was hoping a more experienced Android developer would understand how these things work together.
