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

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.

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"/>

• I am still facing few issues with OPPO devices

I hope this helps someone.
