java.lang.SecurityException：发送短信：uid 10282 没有 android.permission.SEND_SMS

我的应用程序不断崩溃并出现以下错误代码：

java.lang.SecurityException: Sending SMS message: uid 10282 does not have android.permission.SEND_SMS.

这是我的代码

        Button button2 = (Button) findViewById(R.id.text);
        button2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

        String messageToSend = "this is a text";
        String number = "XXXXXX";

        SmsManager.getDefault().sendTextMessage(number, null, messageToSend, null,null);

    }
});

}

尝试在第一个活动的 onCreate 方法中添加此代码，如果仍然存在任何错误，请随时再次与我联系。 这将检查短信权限，并在未授予权限的情况下请求该权限。

Here, 'this' is the current activity

if ((ContextCompat.checkSelfPermission(this, Manifest.permission.READ_SMS) + 
    ContextCompat.checkSelfPermission(this, Manifest.permission.SEND_SMS))
        != PackageManager.PERMISSION_GRANTED) {

// Permission is not granted
// Should we show an explanation?

if (ActivityCompat.shouldShowRequestPermissionRationale(this,"Manifest.permission.READ_SMS") ||
            ActivityCompat.shouldShowRequestPermissionRationale(this,"Manifest.permission.READ_SMS")) {

    // Show an explanation to the user *asynchronously* -- don't block
    // this thread waiting for the user's response! After the user
    // sees the explanation, try again to request the permission.

} else {

    // No explanation needed; request the permission
    ActivityCompat.requestPermissions(this,
                new String[]{"Manifest.permission.READ_SMS, Manifest.permission.SEND_SMS"},
                REQUEST_CODE);

     // REQUEST_CODE is an
     // app-defined int constant. The callback method gets the
     // result of the request.
  }
}

else {
        // Permission has already been granted
}
