关于MIUI悬浮窗权限问题的解决方案

先扯会....好久没写Blog了....这段时间有点小忙...瞎忙.....忙的自己都感觉都不应该.....严重影响了生活质量......生活的幸福指数!!!.....到现在还特么的单身!!!求介绍啊......

MIUI是我个人非常喜欢的ROM....虽然有诸多的不爽....但是搞开发就能理解.....写好一个产品是多么的不易.....好多东西的不可控....精力的有限! 现在买手机都看能不能刷MIUI..不能刷的就犹豫了.....

步入正题.....解决这个问题...无非就是2点

1.跳转

2.判断是否真的打开

......代码打开是别想了....要不然人家也不能弄着玩啊.....除非是你发现了什么....

跳转的思路很简单..手动找到那个界面..看看是哪个Activity.

 　　public static ComponentName getTopComponentName(Context context) {
        ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        List< ActivityManager.RunningTaskInfo > taskInfo = am.getRunningTasks(1);
        ComponentName componentName = taskInfo.get(0).topActivity;
        return componentName;
    }

再通过ComponentName想知道什么不行啊.....不知道怎么执行....能想到这个问题...不应该吧....随便建议一下....跑个线程

下面就是跳转了....

　　/**
     * 打开MIUI权限管理界面(MIUI v5, v6)
     * @param context
     */
    public static void openMiuiPermissionActivity(Context context) {
        Intent intent = new Intent("miui.intent.action.APP_PERM_EDITOR");
        String rom = RomUtils.getRom();

        if (RomUtils.ROM_MIUI_V5.equals(rom)) {
            PackageInfo pInfo = null;
            try {
                pInfo = context.getPackageManager().getPackageInfo(packageName, 0);
            } catch (NameNotFoundException e) {
                Flog.e(e);
            }
            intent.setClassName(SETTINGS_PACKAGE_NAME, "com.miui.securitycenter.permission.AppPermissionsEditor");
            intent.putExtra("extra_package_uid", pInfo.applicationInfo.uid);

        } else if (RomUtils.ROM_MIUI_V6.equals(rom)) {
            intent.setClassName("com.miui.securitycenter", "com.miui.permcenter.permissions.AppPermissionsEditorActivity");
            intent.putExtra("extra_pkgname", context.getPackageName());
        }

        if (isIntentAvailable(context, intent)) {
            if (context instanceof Activity) {
                Activity a = (Activity) context;
                a.startActivityForResult(intent, 2);
            }
        } else {
            Flog.e("Intent is not available!");
        }
    }

很可惜....V5的悬浮窗权限在应用详情里面...

　　@TargetApi(9)
    public static void openAppDetailActivity(Context context, String packageName) {
        Intent intent = null;
        if (Build.VERSION.SDK_INT >= 9) {
            intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
            Uri uri = Uri.fromParts(SCHEME_PACKAGE, packageName, null);
            intent.setData(uri);
        } else {
            final String className = Build.VERSION.SDK_INT == 8 ?
                    SETTINGS_APPDETAILS_CLASS_NAME_22 : SETTINGS_APPDETAILS_CLASS_NAME_B21;
            intent = new Intent(Intent.ACTION_VIEW);
            intent.setClassName(SETTINGS_PACKAGE_NAME, SETTINGS_APPDETAILS_CLASS_NAME);
            intent.putExtra(className, packageName);
        }
        if (isIntentAvailable(context, intent)) {
            context.startActivity(intent);
        } else {
            Flog.e("intent is not available!");
        }
    }

另外加了个Intent的判断

　　/**
     * 判断是否有可以接受的Activity
     * @param context
     * @param action
     * @return
     */
    public static boolean isIntentAvailable(Context context, Intent intent) {
        if (intent == null) return false;
        return context.getPackageManager().queryIntentActivities(intent, PackageManager.GET_ACTIVITIES).size() > 0;
    }

v5, v6不知道怎么判断? 好吧...有点跑题了....

    public static String getSystemProperty() {
        String line = null;
        BufferedReader reader = null;
        try {
            Process p = Runtime.getRuntime().exec("getprop ro.miui.ui.version.name" );
            reader = new BufferedReader(new InputStreamReader(p.getInputStream()), 1024);
            line = reader.readLine();
            return line;
        } catch (IOException e) {
            Flog.e(e);
        } finally {
            IoUtils.close(reader);
        }
        return "UNKNOWN";
    }    

根据返回的是V5还是V6判断

=====完成跳转.....下面就是判断了......自己是没琢磨出来....问的MIUI的工程师.....小帅哥太帅了.....感谢.....

    /**
     * 判断MIUI的悬浮窗权限
     * @param context
     * @return
     */
    @TargetApi(Build.VERSION_CODES.KITKAT)
    public static boolean isMiuiFloatWindowOpAllowed(Context context) {
        final int version = Build.VERSION.SDK_INT;

        if (version >= 19) {
            return checkOp(context, OP_SYSTEM_ALERT_WINDOW);  //自己写就是24 为什么是24?看AppOpsManager
        } else {
            if ((context.getApplicationInfo().flags & 1<<27) == 1) {
                return true;
            } else {
                return false;
            }
        }
    }　　

    @TargetApi(Build.VERSION_CODES.KITKAT)
    public static boolean checkOp(Context context, int op) {
        final int version = Build.VERSION.SDK_INT;

        if (version >= 19) {
            AppOpsManager manager = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE);
            try {
                if (AppOpsManager.MODE_ALLOWED == (Integer)ReflectUtils.invokeMethod(manager, "checkOp", op, 
　　　　　　　　　　　　　　　　　　　　Binder.getCallingUid(), context.packageName())) {  //这儿反射就自己写吧
                    return true;
                } else {
                    return false;
                }
            } catch (Exception e) {
                Flog.e(e.getMessage());
            }
        } else {
            Flog.e("Below API 19 cannot invoke!");
        }
        return false;
    }

到这儿就完事了...没想到牵扯的代码还挺多.......
