我尝试将图像保存到WathsappIMG但是当我去图像库android我没有看到图像和那里的图像进入目录可以从ES文件资源管理器中看到

OutputStream output;
       // Find the SD Card path
        File filepath = Environment.getExternalStorageDirectory();

      // Create a new folder in SD Card
     File dir = new File(filepath.getAbsolutePath()
              + "/WhatSappIMG/");
        dir.mkdirs(); 

     // Retrieve the image from the res folder
        BitmapDrawable drawable = (BitmapDrawable) principal.getDrawable();
        Bitmap bitmap1 = drawable.getBitmap();

        // Create a name for the saved image
        File file = new File(dir, "Wallpaper.jpg" );

        try {

            output = new FileOutputStream(file);

            // Compress into png format image from 0% - 100%
            bitmap1.compress(Bitmap.CompressFormat.JPEG, 100, output); …

我在打开应用程序时创建快捷方式,但问题是创建一个总是打开应用程序的快捷方式,如果我打开应用程序20次然后创建20个快捷方式

我需要只创建一个第一次打开的快捷方式而不是更多

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ShortcutIcon();

   }




private void ShortcutIcon(){

    Intent shortcutIntent = new Intent(getApplicationContext(), Main.class);
    shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    Intent addIntent = new Intent();
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "Whatsapp Imagenes");
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, Intent.ShortcutIconResource.fromContext(getApplicationContext(), R.drawable.icono));
    addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
    getApplicationContext().sendBroadcast(addIntent);
}
