java.lang.SecurityException : Need android. 权限。AttributionSource 的 BLUETOOTH_CONNECT 权限

Question

请理解这个问题可能有点头晕，因为这是我第一次提问。另外，请理解语法可能很奇怪，因为我不擅长英语并使用翻译。
我是一个在 Android 工作室中使用 java 制作应用程序的人。
尝试使用蓝牙时出现连续错误。错误太多，我可以很容易地找到解决方案，但它不适用于我。

我认为中间这句话是错误的原因。

Caused by: java.lang.SecurityException: Need android.permission.BLUETOOTH_CONNECT permission for AttributionSource { uid = 10158, packageName = org.techtown.push.bluetoothtest2, attributionTag = null, token = android.os.BinderProxy@f43a396, next = null }: AdapterService getBondedDevices

但我已经为这个问题应用了解决方案。这是我的 Manifest.xml。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="org.techtown.push.bluetoothtest2">

    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
    <uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE" />
    <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
    <uses-feature android:name="android.hardware.bluetooth" android:required="false"/>
    <uses-feature android:name="android.hardware.bluetooth_le" android:required="false"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.Bluetoothtest2">
        <activity
            android:name=".MainActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

我应用它是因为我看到我需要“android.permission.BLUETOOTH_CONNECT 权限”。但是，错误继续发生。
我是不是误会了什么？还是我在 mainactivty.java 中犯了一个错误？
供您引用，我在做项目时是这样设计的。

minimun sdk : API 16 : Android 4.1 (Jelly Bean)

如果您记下的文件没有问题，请告诉我再次查看 Java 代码。
谢谢你。

Answer 1

由于 Android 6.0 并不是每个权限都被授予只是因为它被放置在 list 中。你必须处理runtime permission与 BLUETOOTH_CONNECT 一起流动一(如何在HERE中索取)

The BLUETOOTH_ADVERTISE, BLUETOOTH_CONNECT, and BLUETOOTH_SCAN permissions are runtime permissions. Therefore, you must explicitly request user approval in your app before you can look for Bluetooth devices, make a device discoverable to other devices, or communicate with already-paired Bluetooth devices.
