wallpaper

I am trying to change Android wallpaper using code. I am using the WallpaperManager class, but with no prevail. I used a .png image in the /drawable directory. I am getting an error that says, "Expected resource of type raw". When I run the application(when that method runs), it crashes. I must be victim of a really stupid mistake. The method changeWallpaper() is run after the user taps a button. Here is my code: public void changeWallpaper(View view) { try{ WallpaperManager wallpaperManager = WallpaperManager.getInstance(getApplicationContext()); wallpaperManager.setResource(R.drawable

I am using the following code to set the wallpaper from an image in a drawable: Intent setAsIntent = new Intent(); setAsIntent.setDataAndType(uri, "image/*"); setAsIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); setAsIntent.setAction("android.intent.action.ATTACH_DATA"); Intent chooserIntent = Intent.createChooser( setAsIntent, "set as"); But when startActivity, it only shows a message: No apps can perform this action I did discover a workaround: Intent intent = new Intent(Intent.ACTION_ATTACH_DATA); intent.addCategory(Intent.CATEGORY_DEFAULT); intent.setDataAndType(uri, "image/jpeg");

We're building an Android app with target SDK 1.6, so it will run on 1.6 devices and higher. We'd like to support Live Wallpapers, which we know is 2.1+ only. Is there a way to build one app with 1.6 SDK as the target, but detect if the device it's running on is 2.1, and only in that scenario call the live wallpaper API. We're trying to avoid having to build a separate 1.6 and 2.1 versions, and would like to be able to support Live Wallpapers for only 2.1 devices. So to be clear- 1 app, that can support 1.6 and higher, and support live wallpapers for 2.1 devices. Any way of doing this? Maybe.
