java - android 短信权限棉花糖

Question

我的应用程序有问题，因为我不知道将“弹出窗口、发送 SMS 的权限、存储访问权限(将消息存储在手机中)”。

这是我的代码

这是一个检查android版本并必要时请求许可的简单示例:

public void checkAndroidVersion(String phoneNumber){

    if (Build.VERSION.SDK_INT >= 23) {
        int checkCallPhonePermission = ContextCompat.checkSelfPermission(RegistrationActivity.this,Manifest.permission.SEND_SMS);
        if(checkCallPhonePermission != PackageManager.PERMISSION_GRANTED){
            ActivityCompat.requestPermissions(RegistrationActivity.this,new String[]{Manifest.permission.SEND_SMS},SEND_SMS);
            return;
        }else{
            sendSms(phoneNumber);
        }
    } else {
        sendSms(mobile);
    }
}

public void sendSms(String phoneNumber)
{
    // Your code goes here
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case SEND_SMS:
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                sendSms(phoneNumber);
            } else {

                Toast.makeText(RegistrationActivity.this, "SEND_SMS Denied", Toast.LENGTH_SHORT)
                        .show();
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}
