“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 t

if("huawei".equalsIgnoreCase(android.os.Build.MANUFACTURER) && !sp.getBoolean("protected",false)) {
        AlertDialog.Builder builder  = new AlertDialog.Builder(this);
        builder.setTitle(R.string.huawei_headline).setMessage(R.string.huawei_text)

+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.

public class Utils {

public static void startPowerSaverIntent(Context context) {
    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)) {
                foundCorrectIntent = true;
                final AppCompatCheckBox dontShowAgain = new AppCompatCheckBox(context);
                dontShowAgain.setText("Do not show again");
                dontShowAgain.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                    @Override
                    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                        editor.putBoolean("skipProtectedAppCheck", isChecked);
                        editor.apply();
                    }
                });

                new AlertDialog.Builder(context)
                        .setTitle(Build.MANUFACTURER + " Protected Apps")
                        .setMessage(String.format("%s requires to be enabled in 'Protected Apps' to function properly.%n", context.getString(R.string.app_name)))

                                context.startActivity(intent);
                            }
                        })
                        .setNegativeButton(android.R.string.cancel, null)
                        .show();
                break;

Add the following permissions in your Android.Manifest

<uses-permission android:name="android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS"/>
<uses-permission android:name="oppo.permission.OPPO_COMPONENT_SAFE"/>
<uses-permission android:name="com.huawei.permission.external_app_settings.USE_COMPONENT"/>

Answer 4

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)

            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) {

        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 {

        }
    } catch (NoSuchMethodException | IllegalArgumentException | InvocationTargetException | IllegalAccessException ignored) {
    }
    return "";
}

Answer 5

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.

Answer 6

Solution for all devices (Xamarin.Android)

Usage:

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

    MyUtils.StartPowerSaverIntent(this);
}

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.
