Android调用系统 Set As Intent

调用方法如下:

Intent intent = new Intent(Intent.ACTION_ATTACH_DATA);
            intent.addCategory(Intent.CATEGORY_DEFAULT);
            intent.setDataAndType(Uri.fromFile(new File("/sdcard/test.jpg")), "image/jpeg");
            intent.putExtra("mimeType", "image/jpeg");
            this.startActivityForResult(
                    Intent.createChooser(intent, "Set as:"), CAMERA_COMPLETE);

需要的权限:

<uses-permission android:name="android.permission.SET_WALLPAPER" />
