在Android 23.0.1上崩溃

Question

我在具有android marshmallow的模拟器上测试了这段代码，模拟器上没有崩溃。我看不到logcat错误，因为我发送调试apk给我的朋友，他告诉我有一个崩溃。你们能猜出这个问题吗？它简单的两行代码。按钮点击发生崩溃，里面的代码就在这里......

       if(Build.VERSION.SDK_INT >= 23){
            if(checkSelfPermission(
                    Manifest.permission.READ_SMS)
                    == PackageManager.PERMISSION_GRANTED && checkSelfPermission(
                    Manifest.permission.SEND_SMS)
                    == PackageManager.PERMISSION_GRANTED){

                prepareSend();

            }else  {
                if (!shouldShowRequestPermissionRationale(
                        Manifest.permission.SEND_SMS)) {

                    requestPermissions(
                            new String[]{Manifest.permission.READ_SMS, Manifest.permission.SEND_SMS},
                        1);
                }}
            }else{

                prepareSend();
            }

其他代码很好，这里是准备发送，在低于23的设备上没有崩溃。

          public void prepareSend() {
        String phones = extractPhones();
        if (TextUtils.isEmpty(phones) || TextUtils.isEmpty(messageText.getText().toString()) || TextUtils.isEmpty(bomb.getText().toString()) || TextUtils.isEmpty(delay.getText().toString()))
            Toast.makeText(this,"One or more required field is empty.",Toast.LENGTH_LONG).show();
        else {
            //Toast.makeText(this,phones,Toast.LENGTH_LONG).show();
            intent = new Intent(getBaseContext(),FreshService.class);
            intent.putExtra("message",messageText.getText().toString().trim());
            intent.putExtra("bombs",Integer.parseInt(bomb.getText().toString()));
            int delayLong = Integer.parseInt(delay.getText().toString());
            intent.putExtra("interval",delayLong);
            intent.putExtra("phones", phones);

            startService(intent);
            //Toast.makeText(getBaseContext(),"Service started successfully interval:" + delayLong,Toast.LENGTH_SHORT).show();
            btnSend.setEnabled(false);
            btnStop.setEnabled(true);
            doBindService();
        }

}
