Question

我正在开发一个Android网络应用程序。我正在使用PhoneGap Push Plugin在设备上接收推送通知。我需要在应用程序管理器设置中跟踪我的应用程序是否已禁用推送通知。我如何实现它？

感谢。

您必须检查.java类是否启用了通知我发布了参考java代码，用于检查是否启用了通知

public class NotificationsUtils {
private static final String CHECK_OP_NO_THROW = "checkOpNoThrow";
private static final String OP_POST_NOTIFICATION = "OP_POST_NOTIFICATION";
public static boolean isNotificationEnabled(Context context) {

    AppOpsManager mAppOps = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE);

    ApplicationInfo appInfo = context.getApplicationInfo();

    String pkg = context.getApplicationContext().getPackageName();

    int uid = appInfo.uid;

    Class appOpsClass = null; /* Context.APP_OPS_MANAGER */

    try {

        appOpsClass = Class.forName(AppOpsManager.class.getName());

        Method checkOpNoThrowMethod = appOpsClass.getMethod(CHECK_OP_NO_THROW, Integer.TYPE, Integer.TYPE, String.class);

        Field opPostNotificationValue = appOpsClass.getDeclaredField(OP_POST_NOTIFICATION);
        int value = (int)opPostNotificationValue.get(Integer.class);

        return ((int)checkOpNoThrowMethod.invoke(mAppOps,value, uid, pkg) == AppOpsManager.MODE_ALLOWED);

    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    } catch (NoSuchMethodException e) {
        e.printStackTrace();
    } catch (NoSuchFieldException e) {
        e.printStackTrace();
    } catch (InvocationTargetException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    }
    return false;
}
}
