如何爲圖像共享提供本地圖像路徑 –

終於對我有用了......沒有任何登錄和權限publish_action ......但安裝在我們的手機原生Android應用程序......

公共無效shareFacebookUsingGraph（）{

ShareOpenGraphObject object = new ShareOpenGraphObject.Builder() 
    .putString("og:type", "books.book") 
    .putString("og:title", "A Game of Thrones") 
    .putString("og:description", "In the frozen wastes to the north of Winterfell, sinister and supernatural forces are mustering.") 
    .putString("books:isbn", "0-553-57340-3") 
    .build(); 

    // Bitmap image = BitmapFactory.decodeResource(getResources(), R.drawable.message_box); 

    File sd = Environment.getExternalStorageDirectory(); 
     File image_file = new File(sd, "sharing_event.jpg"); 
     BitmapFactory.Options options = new BitmapFactory.Options(); 
     options.inPreferredConfig = Bitmap.Config.ARGB_8888; 
     Bitmap bitmap_image = BitmapFactory.decodeFile(image_file.getAbsolutePath(), options); 

    SharePhoto photo = new SharePhoto.Builder() 
    .setBitmap(bitmap_image) 
    .setUserGenerated(true) 
    .build(); 

// Create an action 
ShareOpenGraphAction action = new ShareOpenGraphAction.Builder() 
    .setActionType("books.reads") 
    .putObject("book", object) 
    .putPhoto("image", photo) 
    .build(); 

ShareOpenGraphContent content = new ShareOpenGraphContent.Builder() 
.setPreviewPropertyName("book") 
.setAction(action) 
.build(); 

ShareDialog.show(FinalCardView.this, content); 
}

你想分享的圖片 - 它需要使用SharePhoto照片

SharePhoto photo = new SharePhoto.Builder() 
     .setBitmap(bitmap) 
     .build(); 
SharePhotoContent content = new SharePhotoContent.Builder() 
     .addPhoto(photo) 
     .build();

這樣你就可以得到一個位圖文件

Bitmap bitmap = BitmapFactory.decodeFile(file.getAbsolutePath()
