Get icon resource id of another android app

Is there a way to get the resource id of the icon of another android app? (for example com.android.systemui.R.drawable.ic_xxx

)

I tried context.getApplicationInfo().icon

but returned a long integer. Is it possible?

thank

You can get the Drawable

app icon using:

Drawable icon = getPackageManager().getApplicationIcon( PACKAGE_NAME );

If you're interested in your own application's Drawable resource id, try this:



int resourceID = getResources().getIdentifier( DRAWABLE_NAME , "drawable", PACKAGE_NAME );

Or, if you care about performance, this version is faster, but uses reflection:

try {
      Class resource = R.drawable.class;
      Field field = resource.getField( DRAWABLE_NAME );
      int drawableId = field.getInt(null);
    } catch (Exception e) {}

This method should work for getting the app icon including yours:



String appPackageName=...; //use getPackageName() in case you wish to use yours
final PackageManager pm=getPackageManager();
final ApplicationInfo applicationInfo=pm.getApplicationInfo(packageName,PackageManager.GET_META_DATA);
final Resources resources=packageManager.getResourcesForApplication(applicationInfo);
final Bitmap appIconBitmap=BitmapFactory.decodeResource(resources,applicationInfo.icon);
