Get All Installed Application icons in Android : java.lang.ClassCastException

Question

There is a java.lang.ClassCastException when I am trying to get a installed applications icon.

Here is my code.

public Bitmap getAppIcon         


        

Answer 1

Caused by: java.lang.ClassCastException: android.graphics.drawable.NinePatchDrawable cannot be cast to android.graphics.drawable.BitmapDrawable

Problem :

You are trying to typecast BitmapDrawable to NinePatchDrawable

Solution:

Try this:

public Bitmap getAppIcon(String path) {
        PackageInfo pi = pm.getPackageArchiveInfo(path, 0);
        pi.applicationInfo.sourceDir = path;
        pi.applicationInfo.publicSourceDir = path;
        Drawable icon = pi.applicationInfo.loadIcon(pm);
        Bitmap APKicon = ((NinePatchDrawable) icon).getBitmap();  // cast to NinePatchDrawable
        return APKicon;
    }

PackageManager.GetApplicationInfo returns a Drawable object. It might not be a BitmapDrawable.

You can test whether it is a BitmapDrawable with:

If pm.GetApplicationIcon(packname) Is BitmapDrawable Then ...

If you want to convert a non-BitmapDrawable to a BitmapDrawable then you need to:

• Create a mutable bitmap.
• Draw the drawable with Canvas.DrawDrawable
