I am a developer which working on security related area.Recently I
met a little problem. If I got a app such as android .apk or IOS .ipa.
How can I check whether it has malicious actions?
The first thought came to my mind is to check its manifest. To see
which kind of permission it has requested. But this general method can
not detect some actions such as record the screen snapshot or record
user tap position on screen.
Then I switched to search how app store and google play check the
app which submitted by developers. Turns out that they first check the
certificate or signature of the app to make sure it has been published
by trusted organization. Then statically check the system permission
that the app requested.
I guess there must be some in-depth detection method or theory
which used by google and apple to make sure their app is safe to
download. Can anyone provide me some useful information or website
link that I can learn from?
Thank you.

So this has been such an annoying issue I've been having with facebook.
We :
created a messenger app
verified the web-hook
submitted the app for review
got approval from Facebook
Everything works perfectly if we use the developers and users associated with the app, but for some reason any other user will not work at all!
The only explanation I see why it isn't work is because the app is in development mode, but apparently facebook removed that and replaced it with Access Levels.
I've been looking at documentation and can't find anything! Any directional help that I may have missed would be greatly appreciated!

You are indeed completely right!
The old system, consisting of Development Mode and Live Mode, has been replaced by respectively Standard Access and Advanced Access (cf. this documentation).
Apps in Development Mode can only request Permissions from app users who have a Role on the app or in a Business that has claimed the app. This is the same as Standard Access. Apps in Live Mode can request Permissions from anyone, but only if the Permissions have been approved through App Review. This is the same as Advanced Access. Features, although they cannot be requested from app users but are instead active/inactive, behave the same way.
This snippet was taken from this post.; Side note: They even wrote a paragraph about why they decided to switch and which features/improvements the new update brings - it's on the same site, just below the quote above
Anyhow, due to logistic reasons (supposedly) the update is only being pushed gently into the broad mass:
Access Levels are gradually being applied to all existing Business apps automatically.
You can find the banner on the previously mentioned site:
Summing up: Yes - the modes are actually replaced by their new "level system", though the update might haven't covered your Business app yet (but will so in the near future).
I got this message from API, maybe this covers the reason:
"(#10) Cannot message users who are not admins, developers or testers
of the app until pages_messaging permission is reviewed and the app is
live.", "type":"OAuthException", "code":10, "error_subcode":2018028, "fbtrace_id":"AL....i9"}}
I'm new to app developing I just have a simple question. I have a problem with signing my app before uploading it to the play store so, can I send my project to someone to sign the app for me or it's not safe?
You are handing over complete control over your app to them. They can modify and then sign your app without you even knowing.
Also, you can never ever upload an update to your app if you don't have access to the signing key. They can refuse to sign an update or lose the key, which leaves you in a really bad position.
I think it's worth the time to learn how to sign an APK (either with Android Studio or through the CLI), as you will need to do that every time you want to update your app. Imagine how much time you'll lose asking your friend signing every update.
Here is a great tutorial on how to sign your app with Android Studio: https://developer.android.com/studio/publish/app-signing
I would not recommend it because of what a sign implies. You are basically delegating someone else your responsibilities, but also all the work you did on the project and you expose it to major risks.
Moreover, signing an apk/bundle is pretty straightforward and you will find plenty of tutorials on the web.
The time you will spend doing that will not be wasted, since you learned something.
After extending BaseGameActivity on MainActivity, when you open the game it shows the animation of connecting to Google Play Games but at the end shows the message Failed to sign in. How can i solve it?
You may follow this documentation that describes how to troubleshoot issues that you might encounter while developing Android games with the Play Games SDK.
If you are unable to sign players into your game, first make sure that you have followed the instructions to create your client IDs and configure the games services.
If you still encounter sign-in errors, check the following items to make sure that your game is set up correctly.
Check your metadata tags
Check your package name
Check the certificate fingerprint
Check that test accounts are enabled
If you are using Proguard and are seeing errors on the obfuscated APK, check the target API level on your AndroidManifest.xml. Make sure to set it to 17 or above.

I have a client who would like me to publish his app on Google Play Store. He has given me the .apk, description, icons, and banners.
I am going to buy a developer account ($25) for him but before that I would like to ask you guys that as I didn't actually develop this app. I am only going to publish his app. Is it safe? What key points I should check?
Also, would I still need to have Android Studio JUST to publish an app to Google Play Store? Or the URL below would give me the opportunity to publish my app using website?
https://play.google.com/apps/publish
Please help!
Thank you!
Check the Google Play Store Developer Policy Center to see if it infringes any rules.
https://play.google.com/about/developer-content-policy
I would also consider asking to review the source code as well if your name or company is going to be associated with the product you publish.
So basically uploading an app that copyrights most of someone's legit coding and possibly licensing? Not a good approach.
If you are aware about the terms and conditions, you would be liable for cost and damages because technically it will be under your name if you go forward and if your profiting this commercially, that case would be serious should it be brought forward on complaint.
EDITED
If you doing this on his behalf, he should sign up for Developer account or allow you to put his information in. So that's the safe point. If you are saying it is his app.
My iOS app needs to use Instagram API to load some images, user feedback based on geo location. I requested public_content permissions from Instagram team but got rejected with explanations below even though I filled out as much info as possible. Note I have my app in development only and website looks very minimal but some designs and lots of description was submitted for review.
How to resolve this issue of getting these basic permissions? I googled and I notice this is a common problem.
General issues: Invalid Use Case: The use case descrbied in your submission notes, screencast and website is not a valid use case that
we allow on our Platform. Please see our Permissions Review and valid
use cases description (https://www.instagram.com/developer/review/)
for more information.
public_content: This permission (public_content) does not support the use case you described in your submission notes, screencast and
website. Please review Login Permissions
(http://instagram.com/developer/authorization/) for a comprehensive
list of permissions and valid use cases.
Perhaps this helps. I have tried two times but our app was declined. I will write the submission text one more time. I also want to go more into detail as the new FAQ says that Instagram expects a very detailed submision.
Cheers, Christian
FAQ
My submission was rejected but it was a valid use case. What should I do?
A common reason for rejecting a submission is that we do not have enough information to make an assessment of your app. This can happen if your submission was too short, if it missed important information, if you did not provide a good screencast, your website is not working, etc. Before you submit for review again, make sure to provide a long and clear explanation of what your app does and how you use every permission. Make sure also to provide a video screencast and to follow all our Platform Policies.
What should I write in the submission?
The submission should be long enough for us to understand exactly what your app does and why you need the permissions you are asking for. If your submission is too short or does not explain all parts of your integration, then we may not be able to understand and approve your app. For example, your submission should explain what does your app or company do, which of the approved use cases your integration falls into, who will be using your app, how do your user authenticate with your app, how you use the API to power your integration, how does your product use the data acquired from Instagram, etc.
What should I show in the video screencast?
The video screencast is a very important part of a submission and cannot be omitted. Please make sure that the video clearly shows how your application works, including any Instagram login experience and the usage of every permission you are requesting. Since your app may still be in sandbox mode, you can use data from sandbox users to showcase the integration.
My company is working with multiple clients, should I submit one app per project?
No, we do not approve apps that are created for one-off projects (e.g. a hashtag campaign, an event, a website). You should use a single client_id across all your integrations.
Can I revoke a submission if I made a mistake?
You can't cancel a submission that is in progress. You will need to wait until the submission has been reviewed before you can start a new one.
