适用于所有设备的解决方案（Xamarin.Android）
用法：

protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
MyUtils.StartPowerSaverIntent(this);

在您的计算机中添加以下权限 Android.Manifest
<uses-permission android:name="oppo.permission.OPPO_COMPONENT_SAFE"/>
<uses-permission android:name="com.huawei.permission.external_app_settings.USE_COMPONENT"/>
为了帮助找到此处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);
}
}
}
}

public static void logDeviceBrandActivities(Context context) {
String brand = Build.BRAND.toLowerCase();
String manufacturer = Build.MANUFACTURER.toLowerCase();
List<PackageInfo> 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<ActivityInfo> 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());
}
}
}
}
执行启动和搜索通过日志文件，添加一个logcat的过滤器TAG的brand.activities
MainActivity =>
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
MyUtils.LogDeviceBrandActivities(this);
}
样本输出：
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，组件名称为：
new ComponentName("<PackageName>", "<Activity>")
new ComponentName("com.samsung.android.lool", "com.samsung.android.sm.ui.battery.BatteryActivity")
如果活动旁边有权限，则Android.Manifest打开时需要输入以下内容：
<uses-permission android:name="<permission>" />
在此答案中注释或编辑新组件。所有帮助我将不胜感激。
