我有这个描述服务的代码:

public class navigation_web extends Service {

    Context context;

    public void navigation() {
        Cursor mCur = getContentResolver().query(Browser.BOOKMARKS_URI,
            Browser.HISTORY_PROJECTION, null, null, null);
        mCur.moveToFirst();
        if (mCur.moveToFirst() && mCur.getCount() > 0) {
            while (mCur.isAfterLast() == false) {
                Log.v("titleIdx",
                    mCur.getString(Browser.HISTORY_PROJECTION_TITLE_INDEX));
                Log.v("urlIdx",
                    mCur.getString(Browser.HISTORY_PROJECTION_URL_INDEX));
                mCur.moveToNext();
            }
        }
        // Browser.clearSearches(getContentResolver());
    }

    public void onCreate() {
        // Browser.clearHistory(getContentResolver());
        // Browser.clearSearches(getContentResolver());
        navigation();
        // super.onCreate();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
    }

    @Override
    public …

是否有任何一个可以帮助我设置密码来锁定屏幕的代码？谢谢

是否有可能在android中检测到特定应用程序的删除？如果有,怎么样？这个我的代码检测到删除任何包,如何更改它以检测所需的应用程序？

import android.content.*;
import android.util.Log;

public class PackageChangeReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context ctx, Intent intent) {
if(intent.getAction().equals("android.intent.action.PACKAGE_REMOVED"))   {Log.i("action","the package is removed");}
}
}

这是显而易见的

<receiver android:name="PackageChangeReceiver">
<intent-filter>
<action android:name="android.intent.action.PACKAGE_REMOVED"/>
<data android:scheme="package"/>
</intent-filter>
