有没有人知道 Facebook为什么写错照片
原标题:does anyone know why facebook puts the wrong picture

我有一个在Facebook上共享应用程序的代码, 但是当我共享应用程序时, 它设置了正确的链接, 但错误的应用程序图片

Button bShare = (Button) findViewById(R.id.button7);
    bShare.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            final Intent intent = new Intent(Intent.ACTION_SEND);
            intent.setType("text/plain");
            intent.putExtra(Intent.EXTRA_TEXT, "https://play.google.com/store/apps/details?id=com.myglobaljournal.christmascarol");
            startActivity(Intent.createChooser(intent, "Share with"));
最佳回答

您可以使用"http:// developmenters.facebook.com/tools/debug/og/object?q=https://play.google.com/store/apps/details?id=com.myglobaljournal.christmascarol" rel=“nofollow”>Debug 工具 来检查Facebook如何“看到”这个url。

从结果中你可以看到,没有 og 元标签定义, 所以Facebook 可能从内容中随机拍摄图片 。


Edit

Facebook使用开放图表元标记提取信息,然后用来提供Facebook经验中的分享故事。

您可以在“开放图表协议” 存档版本 中看到一个实例,新版本使用标签,但对于您的需求来说过于复杂。

The only question is: can you any control over the output of the google play store for your app? My guess is that you can t, and if you look at other examples (such as instagram or opera mobile) the image also appears random.
