嘿,我正在尝试在我的 Android应用程序上实现一项服务.服务必须执行活动的相同任务. IE,如果在CallLog.Calls内容提供程序上发生某些更改,则必须通知服务并将数据插入数据库,即使应用程序未运行,我的意思是,服务将在应用程序启动后运行,因此如果应用程序被杀死,服务将继续运行,直到操作系统停止它,对吧？

因此它将在后台运行,收集CallLog.Calls服务上更改的所有数据.但是,该服务没有运行.我在Activity的onCreate()方法中加注它.在Service中,我实现了一个ContentObserver类,它使用onChange()方法,以防CallLog.Calls内容提供程序中的某些更改.

我不知道的是为什么服务没有启动,以及为什么即使我在DDMS视角杀死应用程序它也不起作用.

这是代码.

该Activity名为RatedCalls.java

public class RatedCalls extends ListActivity {

private static final String LOG_TAG = "RATEDCALLSOBSERVER";
private Handler handler = new Handler();
private sqliteDatabase db;
private CallDataHelper cdh;
StringBuilder sb = new StringBuilder();
OpenHelper openHelper = new OpenHelper(RatedCalls.this);
private Integer contentProviderLastSize;
private Integer contentProviderCurrentSize;

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    cdh = new CallDataHelper(this);
    db = openHelper.getWritableDatabase();

    startService(new Intent(this,RatedCallsService.class));
    registerContentObservers();

    Log.i("FILLLIST","calling from onCreate()");

    Cursor cursor = getContentResolver().query(
            android.provider.CallLog.Calls.CONTENT_URI,null,android.provider.CallLog.Calls.DATE + " DESC ");

    contentProviderLastSize = cursor.getCount();

}

class RatedCallsContentObserver extends ContentObserver {
    public RatedCallsContentObserver(Handler h) {
        super(h);
    }

    @Override
    public boolean deliverSelfNotifications() {
        return true;

    }

    @Override
    public void onChange(boolean selfChange) {
        Log.d(LOG_TAG,"RatedCallsContentObserver.onChange( " + selfChange
                + ")");
        super.onChange(selfChange);
        searchInsert();

    }
}

private void searchInsert() {

    Cursor cursor = getContentResolver().query(
            android.provider.CallLog.Calls.CONTENT_URI,android.provider.CallLog.Calls.DATE + " DESC ");

    Log.i("FILLLIST","Calling from searchInsert");

    startManagingCursor(cursor);
    int numberColumnId = cursor
            .getColumnIndex(android.provider.CallLog.Calls.NUMBER);
    int durationId = cursor
            .getColumnIndex(android.provider.CallLog.Calls.DURATION);
    int contactNameId = cursor
            .getColumnIndex(android.provider.CallLog.Calls.CACHED_NAME);
    int numTypeId = cursor
            .getColumnIndex(android.provider.CallLog.Calls.CACHED_NUMBER_TYPE);

    Date dt = new Date();
    int hours = dt.getHours();
    int minutes = dt.getMinutes();
    int seconds = dt.getSeconds();
    String currTime = hours + ":" + minutes + ":" + seconds;

    SimpleDateFormat dateFormat = new SimpleDateFormat("M/dd/yyyy");
    Date date = new Date();

    cursor.movetoFirst();           

            String contactNumber = cursor.getString(numberColumnId);
            String contactName = cursor.getString(contactNameId);
            String duration = cursor.getString(durationId);
            String numType = cursor.getString(numTypeId);
            stopManagingCursor(cursor);
            ContentValues values = new ContentValues();

            values.put("contact_id",1);
            values.put("contact_name",contactName);
            values.put("number_type",numType);
            values.put("contact_number",contactNumber);
            values.put("duration",duration);
            values.put("date",dateFormat.format(date));
            values.put("current_time",currTime);
            values.put("cont",1);

            db.insert(CallDataHelper.TABLE_NAME,values);         
}
    public void registerContentObservers() {

    this.getApplicationContext()
            .getContentResolver()
            .registerContentObserver(
                    android.provider.CallLog.Calls.CONTENT_URI,true,new RatedCallsContentObserver(handler));

}

这就是名为RatedCallsService.java的服务

public class RatedCallsService extends Service {

private static final String TAG = "RatedCallsService";
private static final String LOG_TAG = "RatedCallsService";
private Handler handler = new Handler();
private sqliteDatabase db;
private CallDataHelper cdh;
OpenHelper openHelper = new OpenHelper(RatedCallsService.this);

class RatedCallsContentObserver extends ContentObserver {
    public RatedCallsContentObserver(Handler h) {
        super(h);
    }

    @Override
    public boolean deliverSelfNotifications() {
        return true;

    }

    @Override
    public void onChange(boolean selfChange) {
        Log.d(LOG_TAG,"RatedCallsContentObserver.onChange( " + selfChange
                + ")");
        super.onChange(selfChange);
        searchInsert();

    }
}

@Override
public IBinder onBind(Intent arg0) {
    // Todo Auto-generated method stub
    return null;
}

@Override
public void onCreate() {

    Toast.makeText(this,"Rated Calls Service Created",Toast.LENGTH_LONG).show();
    Log.i(TAG,"onCreate");
    registerContentObservers();

}

@Override
public void onDestroy() {

    Toast.makeText(this,"Rated Calls Service Stopped","onDestroy");
    cdh = new CallDataHelper(this);
    db = openHelper.getWritableDatabase();

}

@Override
public void onStart(Intent intent,int startid) {

    Toast.makeText(this,"Rated Calls Service Started",Toast.LENGTH_LONG).show();
    Log.d(TAG,"onStart");      
    registerContentObservers();

}

private void searchInsert() {

    Cursor cursor = getContentResolver().query(
            android.provider.CallLog.Calls.CONTENT_URI,"Calling from searchInsert");

    int numberColumnId = cursor
            .getColumnIndex(android.provider.CallLog.Calls.NUMBER);
    int durationId = cursor
            .getColumnIndex(android.provider.CallLog.Calls.DURATION);
    int contactNameId = cursor
            .getColumnIndex(android.provider.CallLog.Calls.CACHED_NAME);
    int numTypeId = cursor
            .getColumnIndex(android.provider.CallLog.Calls.CACHED_NUMBER_TYPE);

    Date dt = new Date();
    int hours = dt.getHours();
    int minutes = dt.getMinutes();
    int seconds = dt.getSeconds();
    String currTime = hours + ":" + minutes + ":" + seconds;

    SimpleDateFormat dateFormat = new SimpleDateFormat("M/dd/yyyy");
    Date date = new Date();

    if (cursor.movetoFirst()) {
        do {

            String contactNumber = cursor.getString(numberColumnId);
            String contactName = cursor.getString(contactNameId);
            String duration = cursor.getString(durationId);
            String numType = cursor.getString(numTypeId);           
            ContentValues values = new ContentValues();

            values.put("contact_id",values);

        } while (cursor.movetoNext());
        cursor.close();
    }
}


public void registerContentObservers() {

    this.getApplicationContext()
            .getContentResolver()
            .registerContentObserver(
                    android.provider.CallLog.Calls.CONTENT_URI,new RatedCallsContentObserver(handler));

}

 }

只需看看你是否在清单文件中添加了此服务…….

谢谢…….

我有一个使用vs 2010的c#.net 4应用程序.
我试图导入一个c dll(基于vs 2005).

[DllImport("Card.dll")]

我失败了：

Unable to load DLL ‘Card.dll’: The application has Failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail. (Exception from HRESULT: 0x800736B1)

使用sxstrace.exe我得到：

ERROR: Cannot resolve reference Microsoft.VC80.DebugMFC,processorArchitecture=”x86″

我还发现：

MFC80D.DLL and MSVCR80D.DLL are missing

请注意,这不是DebugCRT,因为此问题是由使用Debug编译的DLL而不是Release引起的.我现在使用Release编译的dll,问题是DebugMFC.

我尝试过任何我能在网上找到的东西.为了节省时间,我将介绍我尝试的内容,所以我不会再次得到这个建议：

1-我已安装Microsoft Visual C 2010 Redistributable Package SP1安全更新

2-我已安装Microsoft Visual C 2008 Redistributable Package

3 – 我已经安装了Microsoft Visual C 2005 Redistributable Package

4 – 我尝试将此应用程序作为“发布”而不是“调试”运行

5 – 我试图将entryPoint设置为DllImport

没有帮助.我仍然得到同样的错误.我没有看到任何其他在线建议,而不是上面列出的建议.
谁能帮我？

因为它说“无法解析引用Microsoft.VC80.DebugCRT,processorArchitecture =”x86“,这意味着您缺少对VC 8.0的调试crt运行时的依赖.这意味着您需要构建一个版本,而不是调试版本的卡.dll.微软没有为调试CRT运行时提供可再发行的软件包.这些软件包只附带visual studio.因此构建一个发布版本的card.dll,这应该有助于你的情况.
