android - 没有READ_SMS权限的android短信验证

Question

我知道使用 Android O，现在我们可以在不需要 READ_SMS 权限的情况下读取短信验证。可以使用 createAppSpecificSmsToken API 来完成。

但是我需要一个完整的例子来演示整个 SMS 验证例程。

Answer 1

没什么大不了的。调用createAppSpecificSmsToken()，SmsManager提供一个PendingIntent. 你得到一个String作为令牌的背部。如果设备接收到带有该令牌的 SMS，则您PendingIntent将运行，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，我将令牌显示在 a 中TextView，因此您可以将其输入到其他设备上的 SMS 客户端，并将令牌绑定到 a ResultActivity。

您指定的组件（例如，ResultActivity）在其附加组件中接收实际的 SMS 消息，您可以使用Telephony.Sms.Intents.getMessagesFromIntent()它来获取它：
