Hi - I'm working on my first Android app and recently it started randomly crashing. By this I mean the app just closes and I'm taken to the home screen as if I've swiped up (search). I get no dialog box or notice or alert that something happened. This does not happen on the iOS build. I'm the only tester on Android unfortunately so I can't tell if it's something with the Android build, or my device. The Android Simulator does not crash either. Furthermore the Expo CLI doesn't say anything either. It's like, as far as code goes, it's fine.
Anyone else had this happen? How do I debug something like this? Thanks!

I LOVE this appA! Probably my most used, and it unfortunatly hangs on the game overview screen, after a short dimming of the screen. Real bummer for me bc everything else is working great for me on Froyo!
...does anyone have this running successfully on FroYo?? Ive tried pushing into system/app thinking protection was maybe an issue but to no success...any help would be greatly appreciated!
There was another thread on here with ppl that had problems with this same app after froyo was installed. It doesnt even show up in the app store for froyo users. I have an off topic question: does androids mlb at bat app show live video feed of games? I kno the iphone app does. Thanks.
no its audio only and i miss this app tempted to go back to cm because i miss my baseball

Only works with 2.1 so far, no 2.2 support thusly the darkened screen.
No wonder... I kept thinking MLB at Bat shut my app
off.
just curious...since the MLB app is just for phone access, has anyone tried connecting with their desktop service with flash? Did it work well? I have a hard time justifying purchasing the android app if i dont get comp access as well, especially since it may be possible to have both.
Have not tried myself...
Anyone maybe have a fix for this since this thread has been started though? Still seems to have same issue.
it works just fine for me running 2.2 manual update
No problems with it either, manual download
I was experiencing the non-responsive dimmed screen as well. I went into the application info screen under Settings >> Applications >> Manage Applications and cleared data, cleared cache, forced stop, reopened...and it worked like with 2.1.
What do you mean manual download... I've been wanting to download this and I can't find it on the marketplace
Hi to every one. i am a newbee and want to develop some comprehensive apps. i got some problem here while developing a testing app. everything is fine. i got no errors in code. but when ever i tried to run the project on emulator or to the real device. i suddenly got an error saying " Unfortunately app has been stopped". what does that mean. i am using eclipse and setting environment properly. working on API level 19 which is by default downloaded with the eclipse package in latest versions. and not any else API has been downloaded by me.
WHAT I Suppose to do right now. want some realtime and reliable solution to this problem.
Com'on devs .. answer please..
Hey guys, first of all, sorry if I post on the wrong section.
I have aquestion for devs. I'm a student developer and I'm learning to develop for Android. Do you guys think I'd necessarily need an Android device or the Android emulator would be enough(maybe for one year or more). I also like w10 mobile and I don't know what to do.
Thanks!!!!!!
Also another question, I'm a really beginner dev, but I'd like to get involved in community development, hacking etc, what do you guys recommend to me? Where should a beginner like me start from?
I am always running the apps on a real device if I can. This is definetly needed if the app uses for example something like networking because these functions will not be available on an emulator. The main reason however for using a real device is that it runs a lot smoother. The emulator can take a long time to boot up and it can be really laggy when running the app. Also when you are holding the phone on your hand you get to see how the app really looks and feels.
Emulator is ok though if there is nothing else available.

Thanks for your reply. Well... the emulator is not really slow on latest versions of android studio... but it does start pretty slow. I'll finally use a real device.
On ADV, how can you test GPS, other sensors?

You can use Android Studio emulator and it will work in most cases. Couple recommendations:
1. Select Android version with Google APIs when creating device
2. Install Intel HAXM (you can find it in SDK manager also) - this will really speed up your emulator including loading time
3. Android Studio 2.0 will be released soon and looks like they will improve emulator performance and functionality there.
Of course you may face something wich is not currently works on emulator but you will face this on a real devices too - some features may work different on devices from different manufacturers. But the chance with facing this kind of troubles is very low when you work on common stuff. Also you can take a look to the 3rd party emulators, like Genymotion.
Anyway I prefer to use real device when developing because I can "feel" it

Start with creating some app which will work with some Rest services, display some sort of lists, images, use database to store data. Just think about creating something useful and interesting for you.

You can test GPS using different apps which mocks your location (you can download apk from play store and install it on emulator) or using the terminal:
1. Connect to emulator with "telnet localhost 5554" command. Maybe you will need to change "5554" with another digits - just look at emulator's window title
2. Set location with "geo fix 12.345 67.89" command
What other sensors you need to test?
Used android emulators a lot, but mostly to test different unusual screen resolutions/dpi combinations.
They're ok speedwise, but you'll never get real feel of your app on AVD. And please, don't release anything, that just been tested only on AVD.
Also AVDs are quite good for recording videos of your app UI using screengrabbers on desktop (SSR - Simple Screen recorder is the best for me so far)
As for beginner's project - try to implement little game. I've started with simple rotating cube example from "Hello Android" book , and this little project ended with game with 3M downloads on play store
Android emulator will work when you begin a project.
If you need more tests or make a formal public apk, you can use real devices.
Best way is use both if you have device - use device. Another android versions, resolutions, sizes etc. test on the emulator.
If standard emulator is too slow, you can use genymotion.
Hi all,
I have an app on the store and on F-Droid which is a multi-threaded port scanner. It's also 100% open source https://github.com/aaronjwood/PortAuthority
I've heard from a few users that their phones are saying my app is trying to send email when it's not (feel free to verify my codebase). I finally got a screen shot from one of them to show the issue which I've attached.
Does anyone have any idea where this comes from? Has anyone seen this kind of behavior before? I'm guessing there's some security software installed on their device which is triggering this alert for them. I've tested this on Android 4, 5, and 6 myself and there are many users that haven't run into this issue. I'm not able to get anyone I know to reproduce this either.
My best guess is that they have something installed which doesn't like when my scan goes to connect to port 25 to determine if it's open or not.
Thanks!
-Aaron

This is almost certainly the cause. All you can really do to figure out exactly app is triggering it is to ask them for their phone model, ROM, and list of apps and start looking for similarities.
I tried doing a search and couldn't find a relevant thread, but I have a few questions...
OK first, the issue that brings me here is the only web browser that I like (Boat) has long been dead and out of development, it's long not been on the play store but I've had the APK for a long time and just transfered it to every new phone I got so I could keep using it. I have tried finding a different browser, but I hate them all, none of them have any of the features I want. My last phone was running Android 9.0 and Boat was still working on it. Well, I got a new phone now (Pixel 4a 5g) that has Android 11 and boat still mostly works... except it crashes if I click the bar at the top to type in a URL and a few other bugs... but otherwise still works flawlessly.
1. So, I'm wondering first is it even OK for someone to look to hire a developer to basically update a dead app? Any website and contact information for the original developer no longer exists, but I don't know if it's OK for someone to take over a dead app like that, if it would be considered stealing or something.
2. Second, well if it's OK... I have the last APKs of the browser and I had used a guide to deconstruct the APK into a project thinking maybe I can figure it out and how to update it so that it still works but... yeah that's not happening. So I have the APK files and the already deconstructed into a project and was wondering where I can ask about hiring a developer just to basically update the app so that it still works (bug fixes only, not really making any changes to the look/feel/etc, just fix any bugs or code that's old and deprecated and doesn't work anymore)? And when I say hire, I mean like actually hire, with real money.

First topic is about licence agreement and legal stuff. It is owned by "Boatmob, Inc." / "Digital Life International Limited" / "Crunchbase Inc.". Although the app was for free, it does not seem to be a free licences. But I am not an expert in this area.
About the browser app itself, I have seen that you were already active here: https://forum.xda-developers.com/t/boat-browser.3821682/
You either need a permission of the owning company and then maintain the app yourself (or via a hired dev), or you have to switch to another and still actively supported browser app.
