Android发送短信

实现发送短信的逻辑：
记录一下遇到的问题：android7.0必须申请权限。

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    Button send_Msg,test01,test02;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        send_Msg = (Button)findViewById(R.id.send_Mes);
        send_Msg.setOnClickListener(this);
    }
    public void onClick(View v){
        if (ContextCompat.checkSelfPermission(this,Manifest.permission.SEND_SMS) != PackageManager.PERMISSION_GRANTED){
            ActivityCompat.requestPermissions(MainActivity.this,new String[]{Manifest.permission.SEND_SMS},1);
        }else {
            Toast.makeText(MainActivity.this,"通信开始",Toast.LENGTH_SHORT).show();
            sendMsg("153****2650","查询状态");               //输入自己的电话
        }
    }

    public void sendMsg(String phoneNumber,String message){
        SmsManager smsManager = SmsManager.getDefault();   //获取短信管理器
//        Intent intent = new Intent("发送成功");
//        PendingIntent sentIntent = PendingIntent.getBroadcast(this,0,intent,0);
        smsManager.sendTextMessage("15388342650",null,"shenmea",null,null);
    }

}
