Permission denial to read from emailprovider in android

I've problem when I want to read com.android.email.provider to get email accounts.

Here is my code to re开发者_运维问答trieve the account :

Cursor c = null;
Uri CONTENT_URI = Uri.parse("content://com.android.email.provider/account");
String RECORD_ID = "_id";
String[] ID_PROJECTION = new String[] {RECORD_ID };        
c = getContentResolver().query(CONTENT_URI,ID_PROJECTION,null, null, null);   

I got a security exception:

java.lang.SecurityException: Permission Denial: reading com.android.email.provider.EmailProvider uri content://com.android.email.provider/account from pid=278, uid=10003 requires com.android.email.permission.ACCESS_PROVIDER

I want to know the account is created or not in some other app. Is there any other way to resolve this so that I can read from the provider.

I have also tried adding the permission in manifest:

<uses-permission android:name="com.android.email.permission.ACCESS_PROVIDER"/>

That didn't help.

Any solution would be greatly appreciated.

Thanks in advance
