我已经创建了推送通知应用程序,我从GCM服务获取消息,但推送通知声音不起作用.当我收到通知时,我需要播放声音.我已将我的代码发布到任何人的帮助下我...

    ComponentName comp = new ComponentName(context.getPackageName(),GCMNotificationIntentService.class.getName());

    startWakefulService(context, (intent.setComponent(comp)));

    setResultCode(Activity.RESULT_OK);

    generateNotification(context);

    System.out.println("received push notification");

    Toast.makeText(context,"received notification",Toast.LENGTH_LONG).show();
  }

private void generateNotification(Context context)

我在将数据插入Database时遇到此异常.我是android初学者,请帮我解决这个问题....我无法插入数据......我发布了我的代码和LOGCAT错误....

公共类Db扩展SQLiteOpenHelper {

public static String databasename="modelnew.db";
private static final int SCHEMA_VERSION = 1;
public static String category_table="category";
public static String Id="categoryid";

我已经使用Glide进行图像加载(Image在我的片段中).并在backpress上处理片段backstack以在片段之间导航.加载图像后,我的片段backstack替换为以下片段

com.bumptech.glide.manager.SupportRequestManagerFragment

因为我现在无法处理backstack,我不希望在片段backstack中附加滑动SupportRequestManagerFragment,我也读过以下链接中的glide doc

http://bumptech.github.io/glide/javadocs/360/com/bumptech/glide/Glide.html#with%28android.support.v4.app.Fragment%29

他们已经提到过,传递上下文会根据context参数将Glide附加到Application生命周期.现在我的要求是在不影响片段反栈的情况下如何使用滑动加载图像,是否可能？或者通过配置Glide选项还有其他方法吗？

有人帮我或建议过来这个问题吗？

在我的应用程序中,我有搜索选项卡,在网格视图中显示带有其名称的图像,现在我想实现搜索功能.我一直在谷歌搜索过去两天,但我没有得到任何解决方案.任何想法或教程0r我怎样才能实现这一目标？

有人帮我这个.

提前致谢.

我已经使用了以下代码,但它在执行Asyntask时出错,而且我已经发布了我的JsonParser类.请指导我如何删除此错误.
