华为手机上的“受保护应用”设置以及如何处理它

适用于所有设备的解决方案 (Xamarin.Android)

用法：

MainActivity =>

protected override void OnCreate(Bundle savedInstanceState)

{

base.OnCreate(savedInstanceState);

MyUtils.StartPowerSaverIntent(this);

}

public class MyUtils

{

private const string SKIP_INTENT_CHECK = "skipAppListMessage";

private static List POWERMANAGER_INTENTS = new List()

{

new Intent().SetComponent(new ComponentName("com.miui.securitycenter", "com.miui.permcenter.autostart.AutoStartManagementActivity")),

new Intent().SetComponent(new ComponentName("com.letv.android.letvsafe", "com.letv.android.letvsafe.AutobootManageActivity")),

new Intent().SetComponent(new ComponentName("com.huawei.systemmanager", "com.huawei.systemmanager.appcontrol.activity.StartupAppControlActivity")),

new Intent().SetComponent(new ComponentName("com.huawei.systemmanager", "com.huawei.systemmanager.optimize.process.ProtectActivity")),

new Intent().SetComponent(new ComponentName("com.coloros.safecenter", "com.coloros.safecenter.permission.startup.StartupAppListActivity")),

new Intent().SetComponent(new ComponentName("com.coloros.safecenter", "com.coloros.safecenter.startupapp.StartupAppListActivity")),

new Intent().SetComponent(new ComponentName("com.oppo.safe", "com.oppo.safe.permission.startup.StartupAppListActivity")),

new Intent().SetComponent(new ComponentName("com.iqoo.secure", "com.iqoo.secure.ui.phoneoptimize.AddWhiteListActivity")),

new Intent().SetComponent(new ComponentName("com.iqoo.secure", "com.iqoo.secure.ui.phoneoptimize.BgStartUpManager")),

new Intent().SetComponent(new ComponentName("com.vivo.permissionmanager", "com.vivo.permissionmanager.activity.BgStartUpManagerActivity")),

new Intent().SetComponent(new ComponentName("com.samsung.android.lool", "com.samsung.android.sm.ui.battery.BatteryActivity")),

new Intent().SetComponent(new ComponentName("com.htc.pitroad", "com.htc.pitroad.landingpage.activity.LandingPageActivity")),

new Intent().SetComponent(new ComponentName("com.asus.mobilemanager", "com.asus.mobilemanager.autostart.AutoStartActivity")),

new Intent().SetComponent(new ComponentName("com.asus.mobilemanager", "com.asus.mobilemanager.entry.FunctionActivity")).SetData(Android.Net.Uri.Parse("mobilemanager://function/entry/AutoStart")),

new Intent().SetComponent(new ComponentName("com.dewav.dwappmanager", "com.dewav.dwappmanager.memory.SmartClearupWhiteList"))

};

public static void StartPowerSaverIntent(Context context)

{

ISharedPreferences settings = context.GetSharedPreferences("ProtectedApps", FileCreationMode.Private);

bool skipMessage = settings.GetBoolean(SKIP_INTENT_CHECK, false);

if (!skipMessage)

{

bool HasIntent = false;

ISharedPreferencesEditor editor = settings.Edit();

foreach (Intent intent in POWERMANAGER_INTENTS)

{

if (context.PackageManager.ResolveActivity(intent, PackageInfoFlags.MatchDefaultOnly) != null)

{

var dontShowAgain = new Android.Support.V7.Widget.AppCompatCheckBox(context);

dontShowAgain.Text = "Do not show again";

dontShowAgain.CheckedChange += (object sender, CompoundButton.CheckedChangeEventArgs e) =>

{

editor.PutBoolean(SKIP_INTENT_CHECK, e.IsChecked);

editor.Apply();

};

new AlertDialog.Builder(context)

.SetIcon(Android.Resource.Drawable.IcDialogAlert)

.SetTitle(string.Format("Add {0} to list", context.GetString(Resource.String.app_name)))

.SetMessage(string.Format("{0} requires to be enabled/added in the list to function properly.\n", context.GetString(Resource.String.app_name)))

.SetView(dontShowAgain)

.SetPositiveButton("Go to settings", (o, d) => context.StartActivity(intent))

.SetNegativeButton(Android.Resource.String.Cancel, (o, d) => { })

.Show();

HasIntent = true;

break;

}

}

if (!HasIntent)

{

editor.PutBoolean(SKIP_INTENT_CHECK, true);

editor.Apply();

}

}

}

}

在您的Android.Manifest中添加以下权限。

为了帮助找到这里未列出的设备的活动，只需使用以下方法来帮助找到正确的活动以供用户打开。

C#public static void LogDeviceBrandActivities(Context context)

{

var Brand = Android.OS.Build.Brand?.ToLower()?.Trim() ?? "";

var Manufacturer = Android.OS.Build.Manufacturer?.ToLower()?.Trim() ?? "";

var apps = context.PackageManager.GetInstalledPackages(PackageInfoFlags.Activities);

foreach (PackageInfo pi in apps.OrderBy(n => n.PackageName))

{

if (pi.PackageName.ToLower().Contains(Brand) || pi.PackageName.ToLower().Contains(Manufacturer))

{

var print = false;

var activityInfo = "";

if (pi.Activities != null)

{

foreach (var activity in pi.Activities.OrderBy(n => n.Name))

{

if (activity.Name.ToLower().Contains(Brand) || activity.Name.ToLower().Contains(Manufacturer))

{

activityInfo += " Activity: " + activity.Name + (string.IsNullOrEmpty(activity.Permission) ? "" : " - Permission: " + activity.Permission) + "\n";

print = true;

}

}

}

if (print)

{

Android.Util.Log.Error("brand.activities", "PackageName: " + pi.PackageName);

Android.Util.Log.Warn("brand.activities", activityInfo);

}

}

}

}

Javapublic static void logDeviceBrandActivities(Context context) {

String brand = Build.BRAND.toLowerCase();

String manufacturer = Build.MANUFACTURER.toLowerCase();

List apps = context.getPackageManager().getInstalledPackages(PackageManager.GET_ACTIVITIES);

Collections.sort(apps, (a, b) -> a.packageName.compareTo(b.packageName));

for (PackageInfo pi : apps) {

if (pi.packageName.toLowerCase().contains(brand) || pi.packageName.toLowerCase().contains(manufacturer)) {

boolean print = false;

StringBuilder activityInfo = new StringBuilder();

if (pi.activities != null && pi.activities.length > 0) {

List activities = Arrays.asList(pi.activities);

Collections.sort(activities, (a, b) -> a.name.compareTo(b.name));

for (ActivityInfo ai : activities) {

if (ai.name.toLowerCase().contains(brand) || ai.name.toLowerCase().contains(manufacturer)) {

activityInfo.append(" Activity: ").append(ai.name)

.append(ai.permission == null || ai.permission.length() == 0 ? "" : " - Permission: " + ai.permission)

.append("\n");

print = true;

}

}

}

if (print) {

Log.e("brand.activities", "PackageName: " + pi.packageName);

Log.w("brand.activities", activityInfo.toString());

}

}

}

}

开机后执行并搜索日志文件，在brand.activities的TAG上添加一个logcat过滤器。

MainActivity =>

protected override void OnCreate(Bundle savedInstanceState)

{

base.OnCreate(savedInstanceState);

MyUtils.LogDeviceBrandActivities(this);

}

示例输出：

E/brand.activities: PackageName: com.samsung.android.lool

W/brand.activities: ...

W/brand.activities: Activity: com.samsung.android.sm.ui.battery.AppSleepSettingActivity

W/brand.activities: Activity: com.samsung.android.sm.ui.battery.BatteryActivity <-- This is the one...

W/brand.activities: Activity: com.samsung.android.sm.ui.battery.BatteryActivityForCard

W/brand.activities: ...

因此，组件名称将是：

new ComponentName("", "")

new ComponentName("com.samsung.android.lool", "com.samsung.android.sm.ui.battery.BatteryActivity")

如果活动旁边有一个权限，则需要在Android.Manifest中添加以下条目才能打开该活动：

请评论或编辑新组件到此回答中。非常感谢您的所有帮助。
