android - Android Studio项目-SMSManager不发送短信

Question

我一直试图通过我的应用程序发送短信，而没有打开默认的短信应用程序。
但是我失败了。
这是我的主要代码

 Snackbar snackbar = Snackbar
                    .make(recyclerView, "This will send a SMS!!!", Snackbar.LENGTH_INDEFINITE).setAction("Confirm", new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {
                    String message;
                            if(type.equals("DELIVERED")){
                                message="Order from " + data.shopz.name + " will be delivered to room  "+orders.get(clickedPosRecycler).custRoom
                                        + " in hostel "+orders.get(clickedPosRecycler).custHostel+" in 10 minutes.";
                            }else{
                            message = "Order placed at "+  data.shopz.name+" has been cancelled .Sorry for the inconvenience. An amount of Rs."
                               + orders.get(clickedPosRecycler).amount+" has been credited back to your account.";
                            }
                            orders.remove(clickedPosRecycler);
                            orderAdapter.notifyItemRemoved(clickedPosRecycler);
                            try{

                                String SENT = "SMS_SENT";
                                String DELIVERED = "SMS_DELIVERED";

                                PendingIntent sentPI = PendingIntent.getBroadcast(thisActivity, 0,
                                        new Intent(SENT), 0);

                                PendingIntent deliveredPI = PendingIntent.getBroadcast(thisActivity, 0,
                                        new Intent(DELIVERED), 0);

                                //---when the SMS has been sent---
                                registerReceiver(new BroadcastReceiver(){

                                                break;

                                //---when the SMS has been delivered---
                                registerReceiver(new BroadcastReceiver(){

                                                         switch (getResultCode())
                                                         {

                                                                 Toast.makeText(getBaseContext(), "SMS delivered",

                                                                 break;
                                                         }
                                                     }
                                                 }, new IntentFilter(DELIVERED));
                                SmsManager smsManager = SmsManager.getDefault();
                            smsManager.sendTextMessage("0"+ mobile, null, message, sentPI, deliveredPI);}catch(Exception e){
                                Toast.makeText(thisActivity, "SMS failed",
                                        Toast.LENGTH_LONG).show();
                            }
                        }
                    });
            snackbar.show();

我已经添加

import android.telephony.SmsManager;

并添加了权限

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.cse.pec.foodapp">

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

我尝试了所有手机号码格式为以下格式的版本
9876543210，+ 919876543210，09876543210（印度号码）

它总是会导致通用故障

到目前为止，我已经在Android 4.4.4、6.0和5.1上进行了测试。它全部失败。

授予该应用许可，以便在您的手机中发送短信。


转到“设置>应用程序>已安装的应用程序>'your_app_name'>应用程序
权限”并启用发送短信的权限。
