I am developing an android app which has a button in one activity and when user clicks that button it should create another activity which should show all my contact information in my own ListView.
My code is as follows
package com.softtrends.practice.contactmanager;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class ContactManagerActivity extends Activity implements OnClickListener{
final int PICK_CONTACT_REQUEST=1;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button contacts=(Button) findViewById(R.id.contacts);
contacts.setOnClickListener(this);
}
@Override
public void onClick(View v){
Intent contactIntent = new Intent(this, ContactsActivity.class);
startActivity(contactIntent);
}
}
package com.softtrends.practice.contactmanager;
import android.app.ListActivity;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.PhoneLookup;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class ContactsActivity extends ListActivity {
private Cursor cur;
private String names[];
private void getData(){
cur = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
null, null,null, null);
startManagingCursor(cur);
names=new String[cur.getCount()];
int nameCol=cur.getColumnIndex(PhoneLookup.DISPLAY_NAME);
int i=0;
while(cur.moveToNext()){
names[i]=cur.getString(nameCol);
System.out.println(names[i]);
i++;
}
cur.close();
}
public void onCreate(Bundle bundle){
super.onCreate(bundle);
getData();
setListAdapter(new ArrayAdapter<String>(this, R.layout.list_view, names));
ListView lv=getListView();
lv.setTextFilterEnabled(true);
}
}
While running this app, it displays the first activity as expected but when I click the button, Force close error is coming and in the logcat the error is showing at the line where I am calling the query method.
My logcat is

some may think that as per the logcat it requires READ_CONTACTS permission. But let me tell all that I have already set this permission in my menifest file. Here is my manifest file.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.softtrends.practice.contactmanager"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<user-permission android:name="android.permission.READ_CONTACTS"/>
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".ContactManagerActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".ContactsActivity"></activity>
</application>
</manifest>
Thank God finally I got the answer, it’s a silly mistake, the answer is instead of uses-permission tag I used user-permission tag in the manifest file.
