Question

我知道使用Android O，现在我们可以阅读短信验证而无需READ_SMS权限。它可以使用createAppSpecificSmsToken API完成。

但我需要一个完整的示例来演示整个SMS验证例程。

Answer 1

没有多少。在createAppSpecificSmsToken()上致电SmsManager，提供PendingIntent。你得到String后退，这是令牌。如果设备收到带有该令牌的SMS，则运行PendingIntent，触发您指定的任何组件。

package com.commonsware.android.sms.token;

import android.app.Activity;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.widget.TextView;

public class MainActivity extends Activity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    SmsManager mgr=SmsManager.getDefault();
    String token=mgr.createAppSpecificSmsToken(buildPendingIntent());
    TextView tv=(TextView)findViewById(R.id.text);

    tv.setText(getString(R.string.msg, token));
  }

  private PendingIntent buildPendingIntent() {
    return(PendingIntent.getActivity(this, 1337,
      new Intent(this, ResultActivity.class), 0));
  }
}

在这里，我在TextView中显示令牌，因此您可以将其键入其他设备上的SMS客户端，并将令牌绑定到ResultActivity。

您指定的组件（例如ResultActivity）会在其附加内容中收到实际的SMS消息，您可以使用Telephony.Sms.Intents.getMessagesFromIntent()来获取该消息：
