Android sets wallpaper and creates desktop icons, android Wallpaper

I wrote a Demo to implement the logic of setting wallpaper and creating desktop icons:

Creating a wallpaper is relatively simple. Convert Drawable into Bitmap and use setWallpaper directly:

Bitmap bitmap = BitmapFactory.decodeResource(Main.this.getResources(), R.drawable.wallpaper);                try {                    Main.this.setWallpaper(bitmap);                } catch (IOException e) {                    e.printStackTrace();                }

Create a desktop icon:

If (! HasShortcut () {addShortcut ();} else {Toast. makeText (Main. this, "the desktop icon already exists", Toast. LENGTH_SHORT). show ();}

Create and delete a desktop icon:

/*** Create a desktop icon for the Program */private void addShortcut () {Intent shortcut = new Intent ("com. android. launcher. action. INSTALL_SHORTCUT "); shortcut. putExtra (Intent. EXTRA_SHORTCUT_NAME, getString (R. string. app_name); // The shortcut name shortcut. putExtra ("duplicate", false); // repeated Intent shortcutIntent = new Intent (Intent. ACTION_MAIN); shortcutIntent. setClassName (this, this. getClass (). getName (); shortcut cut. putExtra (Intent. EXTRA_SHORTCUT_INTENT, shortcutIntent); // icon Intent. export cuticonresource iconRes = Intent. using cuticonresource. fromContext (this, R. drawable. ic_launcher); shortcut cut. putExtra (Intent. EXTRA_SHORTCUT_ICON_RESOURCE, iconRes); sendBroadcast (Distributed cut);}/*** Delete the desktop icon of an application */private void delShortcut () {Intent distributed cut = new Intent ("com. android. launcher. action. UNINSTALL_SHORTCUT "); // The icon name is shortcut. putExtra (Intent. EXTRA_SHORTCUT_NAME, getString (R. string. app_name); String appClass = this. getPackageName () + ". "+ this. getLocalClassName (); ComponentName comp = new ComponentName (this. getPackageName (), appClass); shortcut. putExtra (Intent. EXTRA_SHORTCUT_INTENT, new Intent (Intent. ACTION_MAIN ). setComponent (comp); sendBroadcast (shortcut );}

Determine whether the desktop icon already exists:

private boolean hasShortcut() {        boolean isInstallShortcut = false;        final ContentResolver cr = Main.this.getContentResolver();        final String AUTHORITY = "com.android.launcher.settings";        final Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY + "/favorites?notify=true");        Cursor c = cr.query(CONTENT_URI, new String[]{"title", "iconResource"}, "title=?",                new String[]{Main.this.getString(R.string.app_name).trim()}, null);        if (c != null && c.getCount() > 0) {            isInstallShortcut = true;        }        return isInstallShortcut;    }
