Hey is there a way to get the android app from the device to android studio, so I can look at the source code and furthermore install it on a different device from the android studio itself.
This app is on playstore but only on my office device, i can't see it on my personal phone. I tried getting the link but it says "Item not found" on my phone.
Any Suggestions?
You can get the .apk file from the app you downloaded and decompile it with one of the many available tools online to get the Java bytecode. Keep in mind though that it may be hard to decipher it if the developer has obfuscated his app with something like ProGuard.
The .apk itself should be located in one of the following:
/data/app
/data/app-private
/system/app/
/sdcard/.android_secure (shows .asec files, not .apks)
/sdcard/external_sd/.android_secure

I have to build an app for both android and ios. Among other things, the app provides cloud storage. Now, for ios I have implemented NSFileProviderExtension without providing a ui (basically letting the system handle it), and I can access and manage the cloud by entering the files app, selecting my app and then doing whatever needs to be done.
Now, I searched far and wide for an equivalent for this on android. I have a samsung phone, and when I enter the files app, under the cloud section I can see samsung cloud drive, google drive etc. , and I can manage files there just like I can in my app. But I have no idea what kind of provider I need to implement to achieve this. I have implemented DocumentsProvider, as it seemed to be the most likely candidate, but that doesn't appear in the files app.
I had the same question. My document provider is available in the stock Google "Files" file manager, and all non Samsung apps showing the system file picker but not in "My Files" on Samsung Galaxy phones.
The easiest way to check if your Document Manager working is to attach a file to Gmail (surely on an Android device with your provider installed).
So, hey Samsung! We need you adhering to the Android SAF too a.s.a.p.!
I have a problem running my project on Android Studio. I am working on an Android project that has a native Java library inside it. It was running fine all the time. But suddenly when I open Android Studio, I find this error:
There is also an error in the .gradle of the project:
It says that URI is not registered.
When Android Studio is started, I find this message:
It seems that there is something wrong in Java configuration, but I can't find out what is the problem?
It was running fine all the time
Not on Android, it wasn't.
It seems that there is something wrong in Java configuration
No. You are using classes that are not part of the Android SDK.
The java Swing and AWT API are not part of the Android SDK and thus aren't including with it. You must find an Android equivalent image library to use in your app. There are few good ones around just depends on what functionality you need to have available to you in you app. Try searching Picasso and or Volley. Picasso is very popular and well known. it has a lot of feature including networking functionality for loading images from the web. The Volley library isn't an image library but an networking library that contains some predefined classes for loading images over the internet.
So this just happened to me. I'm not 100% on the details of how I got it working again, but its roughly this (on my Mac):
Quit Android Studio
I went to ~/Library/Application%20Support/ and deleted the AndroidStudio3.2 directory
I relaunched Android Studio and I got some warning dialog about plugins not existing.
Chose the button that is something about reinstalling or fixing (or whatever isn't deleting or ignoring)
Another dialog comes up. There are a bunch of plugins that are in red. Deselect all the red ones. Then reselect all those ones that were previously red.
Android Studio asks you something and if you want to restart Android Studio. Pick the thing that includes restarting.
And once Android Studio restarts, chose to rebuild your project, and then it worked.
Good Luck and I hope this works for you too.
i just made a simple android app with 6 buttons. Each button on click opens a new activity. I installed the app on my device via USB cable from Android studio and it runs fine on my device.
But here rises the problem, when I installed the app on my friends device after sharing via SHAREit the app installed on his device but did not run.
What could be the reason for this? And how can I solve this?
Please help. Thank you
You dont need to create a signed APK if you only want to test it on your friends device and not to run it in a production progress. Android Studio creates an apk automatically which is signed for 365 days. Just open your project in your explorer and go to [ProjectName]\app\build\outputs\apk and select the app-debug.apk.
Make sure instance run in android studio is disabled.
Because if Instance run is enabled when you debug the app on real device through usb debugging it will work properly . but if u share the apk from your device to other device it will not work. It might show an error . App Name Unfortunately Stoped.
If Instance run is enable. you must disable the instance run first. If you don't know how to disable it just google it. After disable the instance run, you must clean project and Build new apk. It will work on all the other devices without generating signed apk.
Hope it may help you.
While building the app what MinSDK version you defined? Do both devices satisfy that criteria?
If you suspect that installing through sharing app is a problem then try attaching your friend device to your laptop and try running the app.
Or
Send the apk through email and let your friend download the apk and install the apk through apkInstaller app.
I have a solution for you:
Install Bluestacks Android Emulator.
Go to Tools, Android and click on Enable Adb Integration to disable it.
In android studios one Android Device for Bluestacks will appear while installation.
Share the installed app through shareit.
It will work on other device.
Hope it helps
Here is the link, where you will find your solution. https://developer.android.com/studio/publish/ check the point 'publish your app', In left column.
Simply follow these steps:
Double click on shift and search for build apk and click on it.
Locate that apk file.
Copy to your physical device or your friend's device... whatever, it will work.
I am new to android and java development although I am an expert with IPTV and I have made the biggest Greek and Cyprus IPTV but since there is a lack of Greek IPTV android apps I decided to make one application.I found IPTVCore on playstore which is made by the developer of the IPTV app.In the description it has a link on an app that uses iptv core github
I downloaded the zip changed the icons and renamed the files. In MainActivity.java I removed the first comments and added my playlist url and changed package name.
I have android studio and eclipse with android addons.
How to make it an apk?
If you mean to simply be able to load it onto a devices to test then both Eclipse and Studio will allow you do this when you elect 'Run' and have a device attached via the USB (with USB debugging enabled). This will actually install the apk on your device so you can test it.
If you mean actually making the apk available for others (via the play store for example) then you should look and the Android publishing documentation:
http://developer.android.com/tools/publishing/publishing_overview.html
In very broad terms, you develop the app, build it, test it etc and then when it is ready for release you build it for release (remove all debug code, test data etc), sign the app, and release it via a marketplace like Play Store, or avi email or your own web site.
One important thing to remember is to version the app properly - the is important for all the obvious reasons (users or support wanting to know the version) but also because the marketplace update mechanisms may use it to check what versions can be updated etc.
Update - answering the question in the comment below:
There are two approaches suggested in the Readme file with the project:
To build you custom IPTV app you can do one of the following:
Clone iptv.example project, change app name, launcher icon, and
package name.
Blockquote
Create new Android project with empty activity and use
the code from MainActivity.java
The second one might actually be simpler for you if you know how to create a simple Android project - just do that and then replace the MainActivity code in the newly created project with the code in the MainActivity file (the only java source file) in the githib project you have downloaded.
I recently installed the Bluestacks Android emulator. I happened to look at the process running under ProcessExplorer and was surprised to see that it is a .NET application.
The HD-Frontend.exe is the Bluestacks UI process and is highlighted yellow because it has loaded the .NET framework. There are a number of other processes associated with Bluestacks and most are also .NET.
Opening the EXE in Reflector.NET also shows that it is .NET.
I thought Android was Java-based. What's going on here?
Android is Java-based, but that does not mean an Android emulator has to be written in Java -- just functionally emulate Android devices.
While BlueStack's site does not list any system requirements for its emulator that I could find, at least a couple sites -- e.g. Bazooka Apps and Android Emulator for PC -- mention .NET as a requirement.
Ultimately the proof of what's going on is right in the process list and Reflector results you found.
its an emulation tool whose job is to read the dex code respond to that how the android phone should respond and not to compile and run that dex so it could be on python or ruby also there is no boundation at all that you have to make android emulator on java becuase android is built upon java.
