Permission Denial when trying to access contacts in Android
I am trying to access the contacts on the device and later display them in a list, however when I try to access them with a cursor, I get an error that I'm missing permissions for READ_CONTACTS but I have already gave permissions in my AndroidManifest.xml
Code where I access Contacts:
public void setupCursor() {
Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
while (cursor.moveToNext()) {
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String number = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Toast.makeText(this, name + ": " + number, Toast.LENGTH_SHORT).show();
}
cursor.close();
}
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="io.github.brady131313.textback" >
<uses-sdk android:minSdkVersion="15" android:targetSdkVersion="21"/>
<uses-permission android:name="ANDROID.PERMISSION.READ_CONTACTS"/>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".ActivityMainSettings"
android:label="@string/app_name" >

</intent-filter>
</activity>
<activity
android:name=".ActivityContactSelect"
android:label="Select Contacts">
</activity>
</application>
</manifest>

Any help will be appreciated!
Answer
Since the new runtime permission model is introduced in Android 6.0,
Hope this code will help if you want to use runtime permission model. You can also see detail implementation and get source code from here.
