StatusBarManager

Question

我想在我的应用程序中使用public static final int DISABLE_NOTIFICATION_ALERTS声明的内部StatusBarManager,下面提到的是我的应用程序中的代码摘录

Object object = getSystemService("statusbar");

    Class<?> statusBarManager;
    try {
        statusBarManager = Class.forName("android.app.StatusBarManager");
        Method[] method = statusBarManager.getMethods();
        Field fld[] = statusBarManager.getDeclaredFields();
        for (int i = 0; i < fld.length; i++) {
            String s = fld[i].toString();

        }
        Class name = object.getClass();

        Field field = statusBarManager
                .getDeclaredField("DISABLE_NOTIFICATION_ALERTS");

        android.util.Log.i("MainActivity", "value of::: " + field);

        Method disable = statusBarManager.getMethod("disable",
                new Class[] { int.class });

        disable.setAccessible(true);

        field.setAccessible(true);
        disable.invoke(object,new Integer(262144));

    } catch (ClassNotFoundException e) {
        // TODO Auto-generated catch block
        Log.i("MAinActivity::", "No Such Class Found Exception");
        e.printStackTrace();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        Log.i("MAinActivity::", " Exception occur");
        e.printStackTrace();
    }

内 AndroidManifest.xml

<permission
    android:name="android.permission.STATUS_BAR_SERVICE"

    />

例外情况如下

它给了我上面提到的例外

Answer 1

您必须使用权限:

<uses-permission android:name="android.permission.STATUS_BAR" />

但是,您只能在系统应用中使用此权限.因此,如果您希望在应用程序上拥有此权限,则必须将其安装为系统应用程序,只能在root设备上完成.
