I am a beginner in android programming.Here i have coded to load images(got using serilizable from previous activity) in viewpager.
The issue that i'm facing - When user is seeing this view pager and presses home button to close the app it crashes and shows error as below in my logcat.I am not getting what's wrong with my code. Your help will be appreciated. Thank You.
My Logcat:
java.lang.RuntimeException: Parcel: unable to marshal value extra.Image@30335200 at android.os.Parcel.writeValue(Parcel.java:1343) at android.os.Parcel.writeList(Parcel.java:717) at android.os.Parcel.writeValue(Parcel.java:1290) at android.os.Parcel.writeArrayMapInternal(Parcel.java:644) at android.os.BaseBundle.writeToParcelInner(BaseBundle.java:1313) at android.os.Bundle.writeToParcel(Bundle.java:1034) at android.os.Parcel.writeBundle(Parcel.java:669) at android.support.v4.app.FragmentState.writeToParcel(FragmentState.java:120) at android.os.Parcel.writeTypedArray(Parcel.java:1197) at android.support.v4.app.FragmentManagerState.writeToParcel(FragmentManager.java:617) at android.os.Parcel.writeParcelable(Parcel.java:1363)
My Code of previous activity from which this fragment gets called:
List<Image> images = new ArrayList<Image>();
images.add(new Image(data_list.get(arg1).getImage().get(0).toString()));//here my images list array gets added in images array
Bundle bundle = new Bundle();
bundle.putSerializable("images", (Serializable) images);
bundle.putInt("position", 0);
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
SlideshowDialogFragment newFragment = SlideshowDialogFragment.newInstance();
newFragment.setArguments(bundle);
newFragment.show(ft, "slideshow");
My Image Model:
public class Image {
private String Image;
private String title;
private String id;
public Image() {
}
public Image(String image, String title, String id) {
Image = image;
this.title = title;
this.id = id;
}
public Image(String image) {
Image = image;
}
public String getImage() {
return Image;
}
public void setImage(String image) {
Image = image;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}

private void displayMetaInfo(int position) {

}
@Override

// adapter
