需要 BLUETOOTH 权限：我在某些意图 Android Studio 中没有权限

Question

I am trying to create an app with a MainActivity that opens other activities. When I use bluetooth for activities other than the Main, it gives me this kind of error. While in my MainActivity this is not a problem.

It tells me that I don't have the permissions:

     Caused by: java.lang.SecurityException: Need BLUETOOTH permission: Neither user 10446 nor current process has android.permission.BLUETOOTH.

while my Manifest.xml specifies the permissions:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapplication_dynahers">

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

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

    <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.MyApplication_DynaHERS">
        <activity
            android:name=".Active_Bluetooth_Activity"
            android:exported="true" />
        <activity
            android:name=".Reset_Force_Activity"
            android:exported="true" />
        <activity
            android:name=".Calibration_Activity"
            android:exported="true" />
        <activity
            android:name=".Graph_Activity"
            android:exported="true" />
        <activity
            android:name=".Using_Version_Activity"
            android:exported="true" />
        <activity
            android:name=".Modify_Interval_Activity"
            android:exported="true"
            android:screenOrientation="portrait" />
        <activity
            android:name=".MainActivity"
            android:exported="true"
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

Where could the problem come from?

Answer 1

Here is my error: I actually put the correct permissions in the Manifest (I may be missing the permission for the location because it is possible to locate a device with bluetooth), but what I forgot to do is check the permissions in the code. This should solve my problem.
