Android之使用ACTION_USAGE_ACCESS_SETTINGS权限检测手机多少天没有未使用其它APP

1 需求

找出手机多少天没有使用的所有APP

2 思路

通过 ACTION_USAGE_ACCESS_SETTINGS权限得到多少天已经使用的APP的包名，然后获取手机所有用户APP，剩下的APP就是多少天没有使用的APP。

3 ACTION_USAGE_ACCESS_SETTINGS权限申请

1）在AndroidManifest.xml文件里面定义权限

2）声明权限后还再需要通过Intent启动方式申请，打开相应的界面，同意当前的APP权限。

            val intent = Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS)            startActivityForResult(intent, REQUEST_SYSTEM_USAGE_ACCESS_CODE)

4 判断是否获取ACTION_USAGE_ACCESS_SETTINGS权限

    /**     * 判断是否已经获取 有权查看使用情况的应用程序 权限     *     * @param context     * @return     */    public static boolean isStatAccessPermissionSet(Context context) {        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {            try {                PackageManager packageManager = context.getPackageManager();                ApplicationInfo info = packageManager.getApplicationInfo(context.getPackageName(), 0);                AppOpsManager appOpsManager = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE);//                appOpsManager.checkOpNoThrow(AppOpsManager.OPSTR_GET_USAGE_STATS, info.uid, info.packageName);                return appOpsManager.checkOpNoThrow(AppOpsManager.OPSTR_GET_USAGE_STATS, info.uid, info.packageName) == AppOpsManager.MODE_ALLOWED;            } catch (Exception e) {                e.printStackTrace();                return false;            }        } else {            return true;        }    }

    /**     * 查看是存在查看使用情况的应用程序界面     *     * @return     */    public static boolean isNoOption(Context context) {        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {            PackageManager packageManager = context.getPackageManager();            Intent intent = new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS);            List list = new ArrayList<>();            //进程间通讯有可能异常            try {                list.addAll(packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY));            } catch (Exception e) {                e.printStackTrace();            }            return list.size() > 0;        }        return false;    }

    /**     * 权限检查     */    fun checkUsedPermission():Boolean {        if(!isStatAccessPermissionSet(this) && isNoOption(this)) {            return false        } else {            return true        }    }

因为我们一开始是用startActivityForResult这种方式打开界面，我们可以在onActivityResult里面进行权限的相关判断再处理

 override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {        super.onActivityResult(requestCode, resultCode, data)        Log.i(TAG, "onActivityResult start requestCode is:" + requestCode)        if (requestCode == REQUEST_SYSTEM_USAGE_ACCESS_CODE) {            var result = checkUsedPermission()            Log.i(TAG, "onActivityResult result is ${result}")            if (result) {                init()            } else {                //finish                Log.i(TAG, "has no ACTION_MANAGE_WRITE_SETTINGS");                ToastUtils.showShort(R.string.text_please_allow_permisson)                finish()            }        }    }

5 检测多久时间内使用了其它APP

 /**         * 查询使用在多少小时使用了app         */        fun getRuningAppsNoContainSelf(context: Context, hour: Int): List {            val runingApps = ArrayList()            val sUsageStatsManager = context.getSystemService(Context.USAGE_STATS_SERVICE) as UsageStatsManager            val endTime = System.currentTimeMillis()            val beginTime = endTime - TimeUnit.HOURS.toMillis(hour.toLong())            val event = UsageEvents.Event()            val usageEvents = sUsageStatsManager.queryEvents(beginTime, endTime)            while (usageEvents.hasNextEvent()) {                usageEvents.getNextEvent(event)                if (event.eventType == UsageEvents.Event.MOVE_TO_FOREGROUND) {                    val pkg = event.packageName                    LogUtil.i("获取使用过的应用", "pkg为${pkg}")                    if (!TextUtils.isEmpty(pkg) && !CLEAN_NOT_CONTAIN_LIST.contains(pkg)) {                        if (!runingApps.contains(pkg)) {                            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {                            }                            runingApps.add(event.packageName)                        }                    }                }            }            return runingApps        }

比如是10天内，我们那个hour参数传递10 * 24
