java.lang.SecurityException: AttributionSource 需要 android.permission.BLUETOOTH_CONNECT 权限答案

【问题描述】：

请理解这个问题可能有点晕，因为这是我第一次提出问题。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。错误太多了，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

但我已经为该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 中犯了错误？

供大家参考，我做项目的时候是这样弄的。

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

如果您记下的文件没有问题，请告诉我重新检查 Java 代码。谢谢。

【解决方案1】：

从 Android 6.0 开始，并不是每个权限都被授予只是因为它被放置在清单中。您必须使用BLUETOOTH_CONNECT 处理runtime permission 流（如何在HERE 中请求）

BLUETOOTH_ADVERTISE、BLUETOOTH_CONNECT 和 BLUETOOTH_SCAN 权限是运行时权限。因此，您必须先在您的应用中明确请求用户批准，然后才能查找蓝牙设备、使设备可被其他设备发现或与已配对的蓝牙设备通信。

【讨论】：

有时您可以在调试手机时摆脱它......但是当您部署到 Play 商店时，它只会崩溃/退出。如果使用颤振，请查看pub.dev/packages/permission_handler

【解决方案2】：

您应该在 Manifest 和 Activity.java 中声明 BLUETOOTH_SCAN 和权限

例如：

AndroiManifst.xml

<uses-permission android:name="android.permission.BLUETOOTH"
        android:maxSdkVersion="30" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"
        android:maxSdkVersion="30" />
    <!-- Needed only if your app looks for Bluetooth devices. -->
    <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
    <uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"/>
    <uses-permission android:name="android.permission.BLUETOOTH_PRIVILEGED"
        tools:ignore="ProtectedPermissions" />

MainActivity.java

    private static String[] PERMISSIONS_STORAGE = {
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.WRITE_EXTERNAL_STORAGE,
            Manifest.permission.ACCESS_FINE_LOCATION,
            Manifest.permission.ACCESS_COARSE_LOCATION,
            Manifest.permission.ACCESS_LOCATION_EXTRA_COMMANDS,
            Manifest.permission.BLUETOOTH_SCAN,
            Manifest.permission.BLUETOOTH_CONNECT,
            Manifest.permission.BLUETOOTH_PRIVILEGED
    };
    private static String[] PERMISSIONS_LOCATION = {
            Manifest.permission.ACCESS_FINE_LOCATION,
            Manifest.permission.ACCESS_COARSE_LOCATION,
            Manifest.permission.ACCESS_LOCATION_EXTRA_COMMANDS,
            Manifest.permission.BLUETOOTH_SCAN,
            Manifest.permission.BLUETOOTH_CONNECT,
            Manifest.permission.BLUETOOTH_PRIVILEGED
    };

和

    private void checkPermissions(){
        int permission1 = ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
        int permission2 = ActivityCompat.checkSelfPermission(this, Manifest.permission.BLUETOOTH_SCAN);
        if (permission1 != PackageManager.PERMISSION_GRANTED) {
            // We don't have permission so prompt the user
            ActivityCompat.requestPermissions(
                    this,
                    PERMISSIONS_STORAGE,
                    1
            );
        } else if (permission2 != PackageManager.PERMISSION_GRANTED){
            ActivityCompat.requestPermissions(
                    this,
                    PERMISSIONS_LOCATION,
                    1
            );
        }
    }
