android - 发送短信不会启动 Activity

Question

我想从我的应用程序发送短信，为此我编写了下面的代码，这非常简单。但我面临的问题是，发送消息时未启动任何 Activity

Method to send a message:

private void sendSMS(Context context, String phone, String msg){
    Intent smsIntent = new Intent(Intent.ACTION_VIEW);

    smsIntent.setData(Uri.parse("smsto:"));
    smsIntent.putExtra("address", phone);
    smsIntent.putExtra("sms_body", msg);
    smsIntent.setType("vnd.android-dir/mms-sms");

    try {
        startActivity(smsIntent);
        finish();
    } catch (android.content.ActivityNotFoundException ex) {
        Toast.makeText(context, "SMS faild, please try again later.", Toast.LENGTH_SHORT).show();
    }
}

Permission added in manifest

<uses-permission android:name="android.permission.SEND_SMS" />

总是显示用catch()写的toast

试试这个:

也没有必要:

<uses-permission android:name="android.permission.SEND_SMS" />

只需使用这段代码:

Intent sendIntent = new Intent(Intent.ACTION_VIEW);
                sendIntent.setData(Uri.parse("sms:"));
                sendIntent.putExtra("sms_body", "Check out My app for your smartphone. Download it today from https://google.com");
                try {
                    startActivity(sendIntent);
                } catch (ActivityNotFoundException e) {
                    e.printStackTrace();                        
                }
