Android Provides error with permission in manifest even If I have already added one( Content Resolver issue?)

Question

Hello Guys Please help me with this one.

While this is how my AndroidManifestXML looks.:

<?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>

This is my error code

These are the resources that I have, I could also provide my other classes too if needed be. I know it says I must included permission for reading contacts but it's already added, that's why I'm wondering how this occured.

Answer 1

Remove your package name from your activity's name;
Change this line:

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

to this:

android:name=".MainActivity"

Or completely remove the package attribute from the beginning of your Manifest, but then you have to write it with every activity's name, like follows:

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

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

And so on.
