"Protected Apps" setting on Huawei phones, and how to handle it

Question

I have a Huawei P8 with Android 5.0 that I'm using for testing an app. The app needs to be running in the background, as it tracks BLE regions.

I've discovered that Huawei has built in a "feature" called Protected Apps, that can be accessed from the phone settings (Battery Manager > Protected Apps). This allows elected apps to keep running after the screen is turned off.

Sensibly for Huawei, but unfortunately for me, it looks like it's opt-in, i.e. apps are out by default, and you have to manually put them in. This isn't a showstopper, as I can advise users in an FAQ or printed documentation about the fix, but I recently installed Tinder (for research purposes!), and noticed that it was put in the protected list automatically.

Does anyone know how I can do this for my app? Is it a setting in the manifest? Is it something Huawei has enabled for Tinder because it's a popular app?

Answer 1

There isn't a setting in the manifest, and Huawei has enabled Tinder because it's a popular app. There isn't a way to know if apps are protected.

Anyway I used ifHuaweiAlert() in onCreate() to show an AlertDialog:

private void ifHuaweiAlert() {
    final SharedPreferences settings = getSharedPreferences("ProtectedApps", MODE_PRIVATE);
    final String saveIfSkip = "skipProtectedAppsMessage";
    boolean skipMessage = settings.getBoolean(saveIfSkip, false);
    if (!skipMessage) {
        final SharedPreferences.Editor editor = settings.edit();
        Intent intent = new Intent();
        intent.setClassName("com.huawei.systemmanager", "com.huawei.systemmanager.optimize.process.ProtectActivity");
        if (isCallable(intent)) {
            final AppCompatCheckBox dontShowAgain = new AppCompatCheckBox(this);
            dontShowAgain.setText("Do not show again");
            dontShowAgain.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    editor.putBoolean(saveIfSkip, isChecked);
                    editor.apply();
                }
            });

            new AlertDialog.Builder(this)
                    .setIcon(android.R.drawable.ic_dialog_alert)
                    .setTitle("Huawei Protected Apps")
                    .setMessage(String.format("%s requires to be enabled in 'Protected Apps' to function properly.%n", getString(R.string.app_name)))
                    .setView(dontShowAgain)
                    .setPositiveButton("Protected Apps", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            huaweiProtectedApps();
                        }
                    })
                    .setNegativeButton(android.R.string.cancel, null)
                    .show();
        } else {
            editor.putBoolean(saveIfSkip, true);
            editor.apply();
        }
    }
}

private boolean isCallable(Intent intent) {
    List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent,
            PackageManager.MATCH_DEFAULT_ONLY);
    return list.size() > 0;
}

private void huaweiProtectedApps() {
    try {
        String cmd = "am start -n com.huawei.systemmanager/.optimize.process.ProtectActivity";
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            cmd += " --user " + getUserSerial();
        }
        Runtime.getRuntime().exec(cmd);
    } catch (IOException ignored) {
    }
}

private String getUserSerial() {
    //noinspection ResourceType
    Object userManager = getSystemService("user");
    if (null == userManager) return "";

    try {
        Method myUserHandleMethod = android.os.Process.class.getMethod("myUserHandle", (Class<?>[]) null);
        Object myUserHandle = myUserHandleMethod.invoke(android.os.Process.class, (Object[]) null);
        Method getSerialNumberForUser = userManager.getClass().getMethod("getSerialNumberForUser", myUserHandle.getClass());
        Long userSerial = (Long) getSerialNumberForUser.invoke(userManager, myUserHandle);
        if (userSerial != null) {
            return String.valueOf(userSerial);
        } else {
            return "";
        }
    } catch (NoSuchMethodException | IllegalArgumentException | InvocationTargetException | IllegalAccessException ignored) {

    return "";

+1 for Pierre for his great solution which works for multiple device Manufacturers (Huawei, asus, oppo ...).

I wanted to use his code in my Android app which is in Java. I inspired my code from Pierre and Aiuspaktyn answers.

    SharedPreferences settings = context.getSharedPreferences("ProtectedApps", Context.MODE_PRIVATE);
    boolean skipMessage = settings.getBoolean("skipProtectedAppCheck", false);
    if (!skipMessage) {
        final SharedPreferences.Editor editor = settings.edit();
        boolean foundCorrectIntent = false;
        for (Intent intent : Constants.POWERMANAGER_INTENTS) {
            if (isCallable(context, intent)) {

To help find the activity of the device not listed here, simply use the following method to help find the correct activity to open for the user

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);
            }
        }
    }
}

Java

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());
            }
        }
    }
}

Execute on startup and search through the log file, add a logcat filter on TAG of brand.activities

MainActivity =>
protected override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);

    MyUtils.LogDeviceBrandActivities(this);
}

Sample Output:

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: ...

So the component name will be:

new ComponentName("<PackageName>", "<Activity>")
new ComponentName("com.samsung.android.lool", "com.samsung.android.sm.ui.battery.BatteryActivity")

If the activity has a permission next to it, the following entry in the Android.Manifest is required to open the activity:

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

Comment or edit the new component into this answer. All help will me much appreciated.

Answer 5

You can use this library to navigate the user to protected apps or autostart:

AutoStarter

If the phone supports autostart feature you can show to the user a hint to enable your app in these apps

You can check by this method:

AutoStartPermissionHelper.getInstance().isAutoStartPermissionAvailable(context)

And for navigating the user to that page, simply call this:

AutoStartPermissionHelper.getInstance().getAutoStartPermission(context)

Answer 6

I'm using @Aiuspaktyn solution which is missing the part of how to detect when stop show the dialog after the user set the app as protected. I'm use a Service to check if the app was terminated or not, checking if it exists.
