I am getting this error when I am trying to read contacts from phone and I included READ_CONTACTS
permission in Manifest file. And the strange thing is that it was working fine in Eclipse but when I converted my project to Gradle and run it in Android Studio I'm getting this error.
logcat says:
Permission Denial: opening provider com.android.providers.contacts.ContactsProvider2 from ProcessRecord{302f069 29282:com.GP/u0a322} (pid=29282, uid=10322) requires android.permission.READ_CONTACTS or android.permission.WRITE_CONTACTS
here is the Manifest code:
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="19" />
<!-- Read Contacts from phone -->
<uses-permission android:name="android.permission.read_contacts" />
<uses-permission android:name="android.permission.read_phone_state" />
<uses-permission android:name="android.permission.GET_TASKS" />
<uses-permission android:name="android.permission.READ_CALL_LOG" />
Due to the Marshmallow update Requesting Permissions at Run Time the read contact permission not work. The sample code is
import android.Manifest;
import android.content.ContentResolver;
import android.content.pm.PackageManager;
import android.database.Cursor;
import android.os.Build;
import android.provider.ContactsContract;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;
import java.util.ArrayList;
import java.util.List;
public class MainActivity extends AppCompatActivity {
// The ListView
private ListView lstNames;
// Request code for READ_CONTACTS. It can be any number > 0.
private static final int PERMISSIONS_REQUEST_READ_CONTACTS = 100;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Find the list view
this.lstNames = (ListView) findViewById(R.id.lstNames);
// Read and show the contacts
showContacts();
}
/**
* Show the contacts in the ListView.
*/
private void showContacts() {
// Check the SDK version and whether the permission is already granted or not.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && checkSelfPermission(Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.READ_CONTACTS}, PERMISSIONS_REQUEST_READ_CONTACTS);
//After this point you wait for callback in onRequestPermissionsResult(int, String[], int[]) overriden method
} else {
// Android version is lesser than 6.0 or the permission is already granted.
List<String> contacts = getContactNames();
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, contacts);
lstNames.setAdapter(adapter);
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,
int[] grantResults) {
if (requestCode == PERMISSIONS_REQUEST_READ_CONTACTS) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// Permission is granted
showContacts();
} else {
Toast.makeText(this, "Until you grant the permission, we canot display the names", Toast.LENGTH_SHORT).show();
}
}
}
/**
* Read the name of all the contacts.
*
* @return a list of names.
*/
private List<String> getContactNames() {
List<String> contacts = new ArrayList<>();
// Get the ContentResolver
ContentResolver cr = getContentResolver();
// Get the Cursor of all the contacts
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
// Move the cursor to first. Also check whether the cursor is empty or not.
if (cursor.moveToFirst()) {
// Iterate through the cursor
do {
// Get the contacts name
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
contacts.add(name);
} while (cursor.moveToNext());
}
// Close the curosor
cursor.close();
return contacts;
}
}
