The official documentation can be found here.

Android Studio – java.lang.SecurityException: Need android.permission.BLUETOOTH_CONNECT permission for AttributionSource

Please understand that the question may be a little dizzy because it’s my first time asking a question. Also, please understand that grammar may be strange because I am not good at English and use a translator.

I’m a person who is making apps using java in Android studios.

There was a continuous error trying to use Bluetooth. There were so many errors that I could easily find a solution, but it didn’t apply to me.

Error Log

I think this sentence in the middle is the cause of the error.

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

But I’ve already applied a solution to the problem. This is my 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>

I applied it because I saw that I needed "android.permission.BLUETOOTH_CONNECT permission." However, errors continue to occur.

Am I misunderstanding something? Or did I make a mistake in mainactivty.java?

For your information, I made it like this when I made a project.

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

If there is no problem with the file you wrote down, please tell me to review the Java code again.
Thank you.

    since Android 6.0 not every permission is granted just because its placed in manifest. you have to handle runtime permission flow with BLUETOOTH_CONNECT one (how to request in HERE)

    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.

    You should declare BLUETOOTH_SCAN and permissions in the Manifest and in the Activity.java

    For example:

    1. AndroiManifest.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" />
    1. 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
    };

    and

        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
            );
        }
    }
