发送 Whatsapp 消息至未保存的号码

Question

我正在尝试向特定号码发送 Whatsapp 消息，而不必保存该联系人。

这是我的代码

 try {
    Uri uri = Uri.parse("smsto: " + smsNumber);
    //Timber.e("smsNumber %s", uri.toString());
    Intent i = new Intent(Intent.ACTION_SENDTO, uri);
    i.setPackage("com.whatsapp");
    startActivity(Intent.createChooser(i, ""));

} catch (Exception e) {
    Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT).show();
}

以及我从中得到的信息

Answer 1

在这里试试这个。这对我有帮助

private void openWhatsApp() {
    String smsNumber = "+26377*********";
    boolean isWhatsappInstalled = whatsappInstalledOrNot("com.whatsapp");
    if (isWhatsappInstalled) {

        Intent sendIntent = new Intent("android.intent.action.MAIN");
        sendIntent.setComponent(new ComponentName("com.whatsapp", "com.whatsapp.Conversation"));
        sendIntent.putExtra("jid", PhoneNumberUtils.stripSeparators(smsNumber) + "@s.whatsapp.net");//phone number without "+" prefix

        startActivity(sendIntent);
    } else {
        Uri uri = Uri.parse("market://details?id=com.whatsapp");
        Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
        Toast.makeText(this, "WhatsApp not Installed",
                Toast.LENGTH_SHORT).show();
        startActivity(goToMarket);
    }
}

private boolean whatsappInstalledOrNot(String uri) {
    PackageManager pm = getPackageManager();
    boolean app_installed = false;
    try {
        pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
        app_installed = true;
    } catch (PackageManager.NameNotFoundException e) {
        app_installed = false;
    }
    return app_installed;
}

 override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (resultCode == Activity.RESULT_OK) {
        if (requestCode == PICK_IMAGE_CODE) {
            if (data != null) {
                val image = data.data
                val number = "9163********"
                    val whatsappIntent = Intent(Intent.ACTION_SEND)
                    whatsappIntent.setPackage("com.whatsapp")
                    whatsappIntent.setType("text/plain")
                    whatsappIntent.putExtra(
                        Intent.EXTRA_TEXT,
                        "I am sending the image for testing"
                    )
                    whatsappIntent.putExtra(Intent.EXTRA_STREAM, image)
                    whatsappIntent.setType("image/*")
                    whatsappIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
                    whatsappIntent.putExtra(
                        "jid",
                        PhoneNumberUtils.stripSeparators(number) + "@s.whatsapp.net"
                    ) //phone number without "+" prefix
                    startActivity(whatsappIntent)
                }

            
        }
    }

}

在清单中：（应用程序标签下方）（适用于 Android 11 支持）

  <queries>
        <package android:name="com.whatsapp" />
        <package android:name="com.whatsapp.w4b" />
    </queries>

它会对你有帮助，对我来说效果很好

Answer 5

在尝试了许多解决方案后，这个解决方案适用于所有 Android 版本

1.在AndroidManifest中添加此内容

<queries>
<package android:name="com.whatsapp" />
<package android:name="com.whatsapp.w4b" />
</queries>

2. 使用此代码的手机号码，带国家代码，不带“+”

     PackageManager packageManager = getPackageManager();
     Intent i = new Intent(Intent.ACTION_VIEW);
     String contact = "91"+"9713*****6" //"Contry code"+"whatsApp number"
   
     try {
         String url = "https://api.whatsapp.com/send?phone=" + contact + "&text=" + URLEncoder.encode("test to send", "UTF-8");
         i.setPackage("com.whatsapp");
         i.setData(Uri.parse(url));
         if (i.resolveActivity(packageManager) != null) {
             startActivity(i);
         }
     } catch (Exception e) {
         e.printStackTrace();
     }
