Example content provider to fix on launcher side the "5 secs delay" security restriction Android has on the Home Button

Kustom5SecsDelayProvider.java

import android.content.ContentProvider;

public class Kustom5SecsProvider extends ContentProvider {
  
    /**
     * Path used by Kustom to ask a 5 secs delay reset
     */
    private final static String PATH_RESET_5SEC_DELAY = "reset5secs";

    @Override
    public boolean onCreate() {
        return true;
    }

    @Nullable
    @Override
    public Cursor query(@NonNull Uri uri,
                        String[] projection,
                        String selection,
                        String[] selectionArgs,
                        String sortOrder) {
        throw new UnsupportedOperationException("Unsupported");
    }

    @Nullable
    @Override
    public String getType(@NonNull Uri uri) {
        // Not supported
        return null;
    }

    @Nullable
    @Override
    public Uri insert(@NonNull Uri uri, ContentValues values) {
        // Not supported
        throw new UnsupportedOperationException("Unsupported");
    }

    @Override
    public int delete(@NonNull Uri uri,
                      String selection,
                      String[] selectionArgs) {
        if(PATH_RESET_5SEC_DELAY.equals(uri.getLastPathSegment()) {
            /**
             * Lets ensure this gets executed only by Kustom
             */
            checkCallingPackage();
            /**
             * This assumes you have a transparent activity that will just call finish() during its onCreate method
             * Activity in this case also provides a static method for starting itself
             */
            AutoFinishTransparentActivity.start(getContext());
            return 1;
        }
        return 0;
    }

    @Override
    public int update(@NonNull Uri uri,
                      ContentValues values,
                      String selection,
                      String[] selectionArgs) {
        // Not supported
        throw new UnsupportedOperationException("Unsupported");
    }

    /**
     * Will check weather or not calling pkg is authorized to talk with this provider
     *
     * @throws SecurityException
     */
    private void checkCallingPackage() throws SecurityException {
        String callingPkg = getCallingPackage();
        if ("org.kustom.wallpaper".equals(callingPkg)) return;
        if ("org.kustom.widget".equals(callingPkg)) return;
        if ("org.kustom.lockscreen".equals(callingPkg)) return;
        throw new SecurityException("Unauthorized");
    }
}

I am not sure what had happen, but the delete method was never called, I have sat klwp as wallpaper, and the 5 secs delay toast still come out. Here is my manifest.

       <provider
        android:authorities="com.bennyv4.fivesecdelaycp"
        android:grantUriPermissions="true"
        android:exported="true"
        android:enabled="true"
        android:name=".util.FiveSecsDelayContentProvider"/>

Yeah, Kustom needs to know that your launcher supports this feature, i need to hardcode it in the app, so if you added the support then open a ticket at help@kustom.rocks mentioning launcher pkg name so i can add it on next release

ok, I got it.
