java - 即使我已经添加了一个，Android也会在 list 中提供权限错误(内容解析器问题？)

Question

大家好，请帮我解决这个问题。

这就是我的 AndroidManifestXML 的样子:

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

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <activity
            android:name="android.jojonarte.com.mycontactresolver.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-sdk android:minSdkVersion="11" android:targetSdkVersion="23"/>
    <uses-permission android:name="android.permission.READ_CONTACTS" />

</manifest>

这是我的错误代码

这些是我拥有的资源，如果需要的话我也可以提供我的其他类(class)。我知道它说我必须包含读取联系人的权限，但它已经添加了，这就是为什么我想知道这是如何发生的。

Answer 1

从您的 Activity 名称中删除您的包名称；
更改此行:

android:name="android.jojonarte.com.mycontactresolver.MainActivity"

对此:

android:name=".MainActivity"

或者从 Manifest 的开头完全删除 package 属性，但随后您必须使用每个 Activity 的名称来编写它，如下所示:

<activity
    android:name="android.jojonarte.com.mycontactresolver.MainActivity">
...
</activity>

<activity 
  android:name="android.jojonarte.com.mycontactresolver.AnotherActivity">
...
</activity>

等等。
