Question

我是Android开发的新手。我需要计算发送和接收的电子邮件数量。我已经尝试过链接中给出的代码如何获取未读gmail邮件的数量（在android上）。我正在运行Android 2.2中的代码。但即使我在清单文件中提到了权限，我也会收到Security异常。

java.lang.SecurityException：权限拒绝：从ProcessRecord打开提供程序com.google.android.gm.provider.MailProvider {40a44ec8 8832：com.android.gmailexample / 10090}（pid = 8832，uid = 10090 ）需要com.google.android.gm.permission.READ_GMAIL或com.google.android.gm.permission.WRITE_GMAIL

以下是我的代码

package com.android.gmailexample;

import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;

 public class GmailCountActivity extends Activity {
   public void onCreate(Bundle savedInstanceState) {
    Log.d("Activity","Inside Oncrete");
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    queryLabels();             
   }

public static final class LabelColumns {
    public static final String CANONICAL_NAME = "canonicalName";
    public static final String NAME = "name";
    public static final String NUM_CONVERSATIONS = "numConversations";
    public static final String NUM_UNREAD_CONVERSATIONS = "numUnreadConversations";
}

public void queryLabels(){
    Log.d("Activity","Inside query label");
    String account="email@company.com";
    Uri LABELS_URI = Uri.parse("content://gmail-ls/unread/");
    Uri ACCOUNT_URI = Uri.withAppendedPath(LABELS_URI, account);
    ContentResolver contentResolver= this.getContentResolver();
    Cursor cursor = contentResolver.query(ACCOUNT_URI, null, null, null, null);

    //iterate over all labels in the account
    if (cursor.moveToFirst()) {
        int unreadColumn = cursor.getColumnIndex(LabelColumns.NUM_UNREAD_CONVERSATIONS);
        int nameColumn = cursor.getColumnIndex(LabelColumns.NAME);
        do {
            String name = cursor.getString(nameColumn);
            String unread = cursor.getString(unreadColumn);//here's the value you need
            Log.d("Name", name);
            Log.d("Unread ", unread);
        } while (cursor.moveToNext());
        Log.d("Unread count", String.valueOf(unreadColumn));
    }
 }
}

和清单文件是

<uses-sdk android:minSdkVersion="10" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
    android:label="@string/app_name"
    android:name=".GmailCountActivity" >
    <intent-filter >
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
</application>
<uses-permission android:name="com.google.android.googleapps.permission.GOOGLE_AUTH"/>
<uses-permission android:name="android.permission.GET_ACCOUNTS"/>
<uses-permission   android:name="com.google.android.providers.gmail.permission.READ_GMAIL"/>
<uses-permission android:name="com.google.android.gm.permission.READ_GMAIL"/>
 <uses-permission android:name="com.google.android.gm.permission.WRITE_GMAIL"/>

我无法找到错误。任何帮助将不胜感激。
