好的，我是 android 开发的新手，所以请多多包涵。我正在关注学习 android 书籍，并且由于没有必要的权限而导致刷新服务无法工作，因此遇到了这个问题。谁能告诉我是什么导致了这个问题？logcat 抛出运行时错误：* java.lang.SecurityException: Not allowed to start service Intent { cmp=com.example.yamba/.RefreshService } without permission com.example.yamba.permission.REFRESH at com.example.yamba。 TimelineActivity.onOptionsItemSelected(TimelineActivity.java:138) *

package com.example.yamba;

import java.util.List;

public class RefreshService extends IntentService {
    static final String TAG = "RefreshService";

    public RefreshService() {
        super(TAG);
    }

    @Override
    protected void onHandleIntent(Intent intent) {
            ((YambaApp) getApplication()).pullAndInsert();

}



    public boolean onOptionsItemSelected(MenuItem item) {
    // TODO Auto-generated method stub

    Intent intentUpdater = new Intent(this, UpdaterService.class);
    Intent intentRefresh = new Intent(this, RefreshService.class);
    Intent intentPrefs = new Intent(this, PrefsActivity.class);
    Intent intentTimeline = new Intent(this, StatusActivity.class);

    switch (item.getItemId()) {
    case R.id.item_start_service:
        startService(intentUpdater);
        return true;
    case R.id.item_stop_service:
        stopService(intentUpdater);
        return true;
    case R.id.item_refresh:
        startService(intentRefresh);
        return true;
    case R.id.item_prefs:

    case R.id.item_status_update:
        startActivity(intentTimeline);
    default:
        return false;

    }

onOptionsItemSelected 用于调用刷新服务。

真的很感激帮助。谢谢！！

你需要permission在你的清单中声明

    <permission 
        android:name="com.example.yamba.permission.REFRESH"        
        android:protectionLevel="signature"
    />

您还需要在清单中声明此 REFRESH 权限。这是如何声明权限的示例代码

<permission
    android:name="A_PERMISSION"
    android:description="@string/broadcast_permission_desc"
    android:label="@string/broadcast_permission_label"
    android:permissionGroup="@string/broadcast_permission_group"
    android:protectionLevel="signature" />
