Question

我正在为本地业务开发B2C应用程序。我将为企业和客户开发单独的应用程序，但为了迎合尚未安装该应用程序的客户，我希望为企业提供功能，使他们可以通过我的业务应用程序从其WhatsApp编号向其客户的WhatsApp发送发票。

我该如何实现？

预先感谢

这取决于您的发票格式，如果是纯文本或图像，对于 Android ，您只需使用Intent即可将其共享给WhatsApp

1。分享文字

public void onClick(View view) {
    String packageName = "com.tencent.mm";          //you can try "com.whatsapp" for WhatsApp or "com.facebook.orca" for Messenger

    if (isAppInstalled(packageName)) {              //if app found
        String text = "I love you";

        Intent intent = new Intent(Intent.ACTION_SEND);

        intent.setType("text/plain");
        intent.putExtra(Intent.EXTRA_TEXT, text);
        intent.setPackage(packageName);

        startActivity(intent);
    } else {
        Toast.makeText(view.getContext(), "WeChat is not installed", Toast.LENGTH_SHORT).show();
    }
}

private boolean isAppInstalled(String packageName) {
    boolean installed = true;

    try {
        getPackageManager().getPackageInfo(packageName, 0); //if package not found, exception will be thrown
    } catch (PackageManager.NameNotFoundException e) {
        installed = false;
    }

    return installed;
}

2。分享图片

shareButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent intent = new Intent(Intent.ACTION_SEND);

        intent.setType("image/*");
        intent.putExtra(Intent.EXTRA_STREAM, imageUri);     //uri from loading onto the page
        intent.setPackage(packageName);             //such as "com.tencent.mm"

        startActivity(intent);
    }
});
