如何通过Android中的whatsapp共享pdf和文本? [英] How to share pdf and text through whatsapp in android?

问题描述

我尝试使用以下代码，但未附加pdf文件.

I tried with the following code but it is not attaching the pdf file.

Intent sendIntent = new Intent();
        sendIntent.setAction(Intent.ACTION_SEND);
        sendIntent.putExtra(Intent.EXTRA_TEXT, message);
        sendIntent.setType("text/plain");
        if (isOnlyWhatsApp) {
            sendIntent.setPackage("com.whatsapp");

        }

        Uri uri = Uri.fromFile(attachment);
        sendIntent.putExtra(Intent.EXTRA_STREAM, uri);
        activity.startActivity(sendIntent);

推荐答案

我遇到了这个问题，我试图从Assets文件夹中打开pdf文件，但是我却无法正常工作，但是当我尝试从Download文件夹中打开(对于示例)，它实际上是有效的，下面是一个示例:

I had this issue where I was trying to open a pdf file from assets folder and I did not work, but when I tried to open from Download folder (for example), it actually worked, and here is an example of it:

File outputFile = new File(Environment.getExternalStoragePublicDirectory
    (Environment.DIRECTORY_DOWNLOADS), "example.pdf");
Uri uri = Uri.fromFile(outputFile);

Intent share = new Intent();
share.setAction(Intent.ACTION_SEND);
share.setType("application/pdf");
share.putExtra(Intent.EXTRA_STREAM, uri);
share.setPackage("com.whatsapp");

activity.startActivity(share);
