发送短信权限不起作用

我想发送一条简单的消息，我已经<uses-permission android:name="android.permission.SEND_SMS"/>在我的清单中，但我总是得到：java.lang.SecurityException: Sending SMS message: uid 10064 does not have android.permission.SEND_SMS.

我检查了这个答案 https://stackoverflow.com/questions/23210056/sms-permissions-not-working-no-matter-where-i-put-the-permission-tag，但还是不行。

这是我的清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.roa.sendsms" >


<uses-permission android:name="android.permission.SEND_SMS"/>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:theme="@style/AppTheme.NoActionBar" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

这是我的代码：

package com.roa.sendsms;

import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.telephony.SmsManager;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    Button sendButton =  (Button)findViewById(R.id.sendButton);
    sendButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            sendSms(phoneNumber, "you get message from roish app!!");
        }
    });
}

private void sendSms(String phoneNumber, String message){
    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, null, null);
}

}

感谢大家。

尝试使用这样的东西。未经测试，但应该可以正常工作。当您在这里发现问题时请留言。

这只是为了展示 Android M 中的权限授予是如何工作的。请通过上面提到的功能来扩展它Android 权限教程网站 http://developer.android.com/training/permissions/requesting.html.

您将需要添加ActivityCompat.shouldShowRequestPermissionRationale http://developer.android.com/reference/android/support/v4/app/ActivityCompat.html#shouldShowRequestPermissionRationale%28android.app.Activity,%20java.lang.String%29检查以匹配最佳实践。我可以扩展这个答案，但我认为没有必要。只需确保您在运行时授予权限（或使用targetSdkVersion低于 23 - 但不建议这样做）

private static final int PERMISSION_SEND_SMS = 123;

private void requestSmsPermission() {

    // check permission is given
    if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
        // request permission (see result in onRequestPermissionsResult() method)
        ActivityCompat.requestPermissions(thisActivity,
            new String[]{Manifest.permission.SEND_SMS},
            PERMISSION_SEND_SMS);
    } else {
        // permission already granted run sms send
        sendSms(phone, message);
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {

            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // permission was granted
                sendSms(phone, message);
            } else {
                // permission denied
            }
            return;
        }
    }
}

private void sendSms(String phoneNumber, String message){
    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, null, null);
}
