java - 从 Android fragment 调用时权限被拒绝。使用权限已设置

Question

我在这里遇到了一个小问题，这让我发疯。 我想在 Android 中用 ACTION_CALL Intent 调用一个人，我在一个 fragment 中使用以下代码来完成:

Intent callIntent = new Intent(Intent.ACTION_CALL);
       Ansat a = container.adapter.getItem(position);
       callIntent.setData(Uri.parse("tel:" + a.mobil.replace(" ", "").trim()));
       container.startActivity(callIntent);

容器 是传递给 fragment 的主要 Activity 上下文，因为 fragment 没有自己的 Activity 。

我已经在 Android manifest 中设置了权限:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.SEND_SMS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.CALL_PHONE" />

<permission
    android:name="mithfogvuc.android.svhfvuc.dk.app.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />

<uses-permission android:name="mithfogvuc.android.svhfvuc.dk.app.permission.C2D_MESSAGE" />

<uses-feature
    android:name="android.hardware.camera"
    android:required="true" />

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

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MainActivity"
        android:screenOrientation="portrait" />
    <activity
        android:name=".NewsActivity"
        android:screenOrientation="portrait" />

    <receiver
        android:name="com.google.android.gms.gcm.GcmReceiver"
        android:exported="true"
        android:permission="com.google.android.c2dm.permission.SEND">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />

            <category android:name="mithfogvuc.android.svhfvuc.dk.app" />
        </intent-filter>
    </receiver>

    <service
        android:name=".GCMPushReceiverService"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        </intent-filter>
    </service>
    <service
        android:name=".GCMRegistrationIntentService"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.android.gms.idd.InstanceID" />
        </intent-filter>
    </service>

    <activity
        android:name=".FravaersregistreringActivity"
        android:screenOrientation="portrait" />
    <activity
        android:name=".FremmoederegistreringActivity"
        android:screenOrientation="portrait"/>
</application>

为什么会出现以下错误:

FATAL EXCEPTION: main
      Process: mithfogvuc.android.svhfvuc.dk, PID: 23045
      java.lang.SecurityException: Permission Denial: starting Intent {

Answer 1

从 Android 6.0(Api lvl 23)开始，操作系统允许用户撤销应用程序的权限。你需要调查Runtime Permissions

看来您的应用需要轮询其中一种 requestPermissions() 方法才能获得访问 call_phone API 的权限!
