I heard myself finding Obs' virtual cam in Android Studio in an Android emulator for 6 hours, but only my plugged in cam is recognized. How else can I do that, I have this possibility in my head for which I have not found a solution online. I have to try the virtual cam as an applied cam or a real cam. or if someone has another idea please say and no, I have to use the virtual cam from Obs so that I have a screen and cam on the virtual cam. I ask for help! Thank you for the coming comments.

ssssssssssssooooooooooo android studio doesn't have a java class under its new tab can't figure it out. have considered nuking.

brief overview of what I want my app to do, it takes in the previous configured wifi information and saves them to a table. I have everything working apart from these two problems: Problem 1: So whenever I try and check if the wifi is enabled on the device, the app will crash. Here is the code for the Wifi problem: public void checkWifiState() { if(!wifi.isWifiEnabled()) { Toast.makeText(getApplicationContext(), "Wifi is disabled, please enable it", Toast.LENGTH_SHORT).show(); wifi.setWifiEnabled(true); } } EDIT: found out that wifi.setWifiEnabled(true); is what is breaking the app for Problem 1. Problem 2: I want to drop my table and recreate it, whenever the user trys to press the button to check previous connections. The reason for this is becuase I don't want duplicate data in the database. here is the code for the SQLite problem: this is in a seperate java file called DatabaseHelper that extends SQLiteOpenHelper public void dropTableAndCreateNew() { SQLiteDatabase db = this.getWritableDatabase(); db.delete(TABLE_NAME,null,null); onCreate(db); } I have tried setting the whereClause to "1" on the delete method. It still crashed when I tried to run it on my phone.

Alright, so I'm trying to make an android location app in Android Studio in which the user presses a button and the longitude and latitude of their location is displayed in 2 text views below. The problem I'm having is that I don't really know how to print the coordinates to the textviews on a button press. public class MainActivity extends AppCompatActivity { private LocationListener locationListener; private LocationManager locationManager; private TextView latText; private TextView longText; private Button requestButton; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); requestButton = (Button) findViewById(R.id.requestButton); latText = (TextView) findViewById(R.id.latText); longText = (TextView) findViewById(R.id.longText); LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE); LocationListener locationListener = new LocationListener() { @Override public void onLocationChanged(Location location) { makeUseOfNewLocation(location); } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } @Override public void onProviderEnabled(String provider) { } @Override public void onProviderDisabled(String provider) { } }; }; locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener); } } Here's the code (there are some errors in the code I think but it's like 4am so ill fix it later), most of which is from here (https://developer.android.com/guide/topics/location/strategies.html), as I'm trying to understand how this will work. Any help would be much appreciated, thanks

Hey guys, I'm new on working with Android Studio and Android developing at all. I'm trying to learn a few things and one of the few things that I want to learn the most is making an application look good on large range of devices. I've 4 phones that I can test with on site but I wanted to get a nice range of virtual devices with which I can test too. I've started to make my own devices with help from GSM Arena for specs but it is really slow on a small laptop. If anyone of you can help me with some virtual machines I'll be really happy! Thanks in advance!

Hello I would like to learn android app development. I have made some basic programs in eclipse and now want to move to Android Studio. I currently have a Dell laptop with an Intel Pentium 2117u and 4 gb of ram. Android Studio works but performance is lacking. My main question is will the android emulator need a dedicated graphics card? Currently I'm looking at the Intel Core i3-6100 paired with XFX Radeon R7 360 2gb. I would like to use it for light gaming but it is not a priority. So would I benefit from a faster processor with integrated graphics or is the i3 paired with a gpu a better idea?

Can a install HAXM and run Android Studio Emulator smoothly on intel i9 9900k?

I am a beginner with android app development and am working on a little project for a converter app. I want it to be able to convert currencies. So I have been hearing about APIs and was wondering if there was an API out there that could help me with this and how do I go around this. I am not asking for steps specifically for this but like a general tutorial on just how to use and implement APIs in android studio, maybe like a link to a tutorial or a step to step on how to do this generally so if I ever need to use APIs ever again I wouldn't need to bother anyone again.

Hello everyone, I'm wondering if someone here could be of help to me. I have a AMD A10-5800K CPU (don't judge me) and wish to run Android emulation on it. Now HAXM isn't installing for me since i don't have an Intel processor and i have seen solutions to try the "ARM EABI v7a System Image" but still my emulator gives me the following error: When I open task manager and go under CPU i can se that virtualization is Enabled. Is there something I can do to make my emulator work on a non Intel CPU?

Hi, I'm planning to build budget workstation for Game and Android Dev. I'm working in Android Studio and Unity/Unreal Engine. From time to time I also work in Visual Studio on .NET apps. Is it enough to buy i5 8600K or do I need i7 8700 or Ryzen 2700X (same price), and what is my best option. Thanks

I am in the process of making an app for class. The needs two buttons and one Text View. One of the buttons is the setup: sets the joke up and changes the text view. Second Button is the punch Line: changes the textview again to reveal the joke. I am having troubles by over writing the text view the second time around. IT works on the first try to set up the joke. I can't get it to over ride the second time to show the joke. First time posting Android studio code here. So bare with me and Thanks again!

Hello, I wanted to know the best tutorial for Android Studio, i searched and i cant find a good one. so if you know any good ones just replay with a link with it.

I want to convert some of the apps I have made in App Inventor to Android Studio so I can see the code and try to understand how the code works. I need something to convert it so I am able to open it in Android Studio Thanks in advance!

I want to try reverse engineering some apps, for learning purposes, and I'm not sure how i can import existing APKs into android studio to see the code.

This is my first time developing an app and if there is anybody who i could just contact with quick questions, it would be very helpful. I keep having to halt my production because of silly questions. right now I am stuck because I created a background drawable for my login page, but it wont show up when i run the app on my gs4. I am assuming it is because the image i created is 1440x2560 and the gs4 screen is not. If somebody could help me with this and continue to be able to help me i would appreciate it a lot.
