Generate Unsigned Apk Android Studio

Your question is not clear to me. how can we make APKs from the code? or how do I make APK from an existing application(installed from play store)? If I consider the first one then there are a ton of frameworks available to get your job done. Select whatever framework you wish to use. Then follow it's documentation to convert your code into an APK. For the second case use any back-up application to make the APK for an installed application. I won't suggest people to search for an APK file on the internet . Backing up an application is always safer than downloading it from the internet. Thanks.

Android Studio sets up new projects to deploy to the Android Emulator or a connected device with just a few clicks. Once your app is installed you can use Apply Changes to deploy certain code and resource changes without building a new APK. To build and run your app follow these steps In the toolbar select your app from the run configurations drop-down menu. Click Run . Sync tab Displays tasks that Gradle executes to sync with your project files. Similar to the Build tab if you encounter a sync error select elements in the tree to find more information about the error. Toggle view Toggles between displaying task execution as a graphical tree and displaying more detailed output from Gradlethis is the same output you see in the Gradle Console window on Android Studio 3. and earlier. Navigate to Build Execution Deployment Compiler. Click OK to save and exit. Navigate to Build Execution Deployment Deployment. Click OK. ordered-list Note Some s of changes don't cause Apply Changes to fail but still require you to restart your app manually before you can see those changes. For example if you make changes to an activity's onCreate() method those changes only take effect after the activity is relaunched so you must restart your app to see those changes. Limitations of Apply Changes Apply Changes is designed to speed up the app deployment process. However there are some limitations for when it can be used. If you encounter any issues while using Apply Changes file a bug. Code changes that require app restart Some code and resource changes cannot be applied until the app is restarted including the following Adding or deleting a method or field Changing method signatures Changing of methods or classes Changing class inheritance Changing values in enums Adding or removing a resource Changing the app manifest Changing native libraries (SO files) Libraries and plugins Some libraries and plugins automatically make changes to your app's manifest files or to resources that are referenced in the manifest. These automatic updates can interfere with Apply Changes in the following ways If a library or plugin makes changes to your app's manifest you can't use either Apply Code Changes or Apply Changes and Restart Activity and have to restart your app before you can see your changes. If a library or plugin makes changes to your app's resource files you can't use Apply Code Changes and you must use Apply Changes and Restart Activity to see your changes. You can avoid these limitations by disabling all automatic updates for your debug build variants. For example Crashlytics updates app resources with a unique build ID during every build which prevents you from using Apply Code Changes and requires you to restart your app's activity to see your changes. You can disable this behavior so that you can use Apply Code Changes alongside Crashlytics with your debug builds. Code that directly references content in an installed APK If your code directly references content from your app's APK that's installed on the device that code can cause crashes or misbehave after clicking Apply Code Changes . This behavior occurs because when you click Apply Code Changes the underlying APK on the device is replaced during installation. In these cases you can click Apply Changes and Restart Activity

Yes - you can create an Alarm application for Android from my GitHub s . Instructions are Install Android Studio s - follow the installation instructions. Open Android Studio. Enter s code into the URL box then press Clone . You can run the APK in multiple ways. You can email the APK to yourself open it on an Android device and install it from there or you can host it online somewhere and download it or put it in an OTG USB stick. You can also run it easily from Android Studio on an Emulator or over ADB to an Android Device - follow the documentation on Build and run your app s for that. ordered-list

To generate a release build for Android run the following climand $ ionic cordova build android --prod --release code This will generate a release build based on the settings in the code in the platforms code directory of an app. An Ionic app will have preset default values in this file but this can be changed to customize builds. Signing an APK First the unsigned APK must be signed. If a signing key has already been generated skip these steps and use that one instead. Generate a private key using the keytoolmand thates with the Android SDK $ keytool -genkey -v -keystore -alias alias_name -keyalg RSA -keysize 248 -validity 1 code Once thatmand has been ran and its prompts have been answered a file called code will be created in the current directory. To sign the unsigned APK run the jarsigner tool which is also included in the Android SDK $ jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore alias_name code Finally the zip align tool must be ran to optimize the APK. The zipalign code tool can be found in code . For example on macOS with Android Studio installed zipalign code is in ~ code $ zipalign -v 4 code This generates a final release binary called that can be accepted into the Google Play Store.

If you are familiar with web technology building web appi would rmend you use phonegapit help you to build cross platform application not just android and ios it supp windows phoneblackberrymobile web app. It is using htmlcss and javascript phonegap is actually powered by cordova which is container to wrap your app into ios and android and others.

You will have your ..apk file generated in a new folder called out within your project folder. Note! This is an unsigned apk file. For signed apk file you can resesrch yourself and post an appropriate answer here to supp the others u263au263anOther thaan phonegap xamarin is a good choice for cross platform as well it usimg c# visual studio support it. nHowever i am using phonegap now.! It is Good and easy to learn. It require a lot javascript effort to make a good one but for normal application it will be fine for average JavaScript knowledge.n**according to your situation**nI guess yes there are someone using rails for phonegap as well but i dont know how to implement this.

Register for Google Play nThe first step in publishing is to register for Google Play at the Google Play publisher site. The process is relatively straightforward and should only take you a few minutes. Note There is a $25 USD charge to register. Are you going to Sell your App? nIf you want to sell your apps instead of offering them for free with ads you also need to set up a Google Wallet Merchant account as described in the Getting Started with Publishing article in Google Play's help.n Note We rmend turning ads off when selling your app on Google Play. An Andromo subscription is required to do this. Prepare to Publish nThe publishing process in Google Play can be a lot quicker if you have all of the store listing contentplete and available before you start. So when you're ready to publish your app here are the items you should have available Your final Andromo application file (APK) to be uploaded. It must be under 5MB in size to be accepted. The title for your app (max 3 characters). A description of your app (max 4 characters). High-res icon 512 x 512 32-bit PNG (with alpha). At least 2 screenshots are required overall (Max 8 screenshots per ) JPEG or 24-bit PNG (no alpha). Min length for any side 32px. Max length for any side 384px. (You can upload a maximum of 8 screenshots per . Types include Phone 7-inch tablet and 1-inch tablet.) nOptional items that can be updated later include Optional promo (8 characters) and promo graphic. Promo graphic needs to be 18w x 12 h JPG or 24-bit PNG (no alpha). Screenshots Only 2 are required but you can upload a maximum of 8 screenshots per . Types include Phone 7-inch tablet and 1-inch tablet. Feature graphic 124w x 5h JPG or 24-bit PNG (no alpha). Add New Application nOnce you've registered you can log in to your Google Play developer account and begin publishing your application via the + Add new application button. The first thing you'll see is a dialog asking for the default language and the title of your app. You're then presented two options Upload APK and Prepare Store Listing. The one you start with is up to you but for this article we'll assume you'll choose the upload first. Upload APK nThis step is the process of uploading your application Android Package File (APK). A to this file is emailed to you whenever you successfully build your application and can be downloaded at any time from your projects section on Andromo. Click the Upload APK button and browse for your application file to upload. You'll see a Save Draft button on the dialog box after you upload the APK. Once youplete this step you'll see a checkmark listed beside APK along the left hand side of the screen. The next step is to prepare your store listing. Store Listing nThe Store Listing controls what your end users will see when they find your application in Google Play. The available listing details are described in detail in Google uploading applications help topic. This step involves submitting content such as your title description icon screenshots categorization contact details and privacy policy. As discussed in the Prepare to Publish section some of these items are required while others are optional. When you're finished click the save you've entered all of the required information you'll see a checkmark listed beside the Store Listing along the left hand side of the screen. The next step is toplete the Pricing & Distribution can learn more about graphic assets in the article Graphic and Image Assets in Google Play's help. Information on taking screenshots can be found in the How to take screenshots of your application knowledge base article. Pricing & Distribution nIn this section you define the pricing details for your app (free or paid) where you want it available and consent options. When you're finished save your changes and if you've entered all of the required information it will show a checkmark next to Pricing & Distribution along the left-hand side. Publishing your App nIf you've submitted all of the required information a Publish this app button will be enabled on the page. Your application should appear in the store usually after a few hours (but could take longer). If you've included AdMob in your app don't forget to your app which you can normally do about 24 hours after it's been published. Editing your Listing nIf you want to go back to edit your listing or upload a new version of your application you can. When you make your changes simply save them and they should be live in the store in twenty minutes or so. Note This can sometimes take quite a while so be patient.

I knew only C++ and started learning Android this Feb 1 Following are the things what I experienced during my journey SETTING UP PHASE 1. Maybe the most hectic part for a beginner as well as for an expert. You have to install Java (jdk and jre bothesbined so don't worry) and then Android Studio. Note Avoid Eclipse. italic It's old. The best tutorial for setting up these is Newboston. Though the video is old the procedure is still the same and he has the best explanation. LEARNING PHASE 1. Video tutorials are better than blogs because written contents may get you confused. So go for youtube! 2. Make sure your tutorials videos are mostly from this year ie latest since Android Studio (the software inwhich you write Android codes) has drastically been upgraded this year to version 2.1 (2.2 also which is in beta or preview). All the old tutorials will pretty much get you confused later on because eventually you will have to use the latest edition. Note please don't use Eclipse! Go for Studio. 3. Tutorials for the latest Android Studio are hard to find. Google and Youtube are crowded with old content. So my opinion is First watch videos of Newboston or Slidenerd. These are old videos but will help you in getting a very firm grip on the concept. Just watch and learn them. Don't try coding with these since they are old and won't support on the new Android Studio 2.1 or 2.2 After learning from above then you may go for Oum Saokosal videos. His videos have latest content and he constantly replies yourments too. So you can ask him doubts too. You may use this content for coding. There's another guy called Prabeesh. I think his content is also well updated and has a lot of content than Oum. 4. Never use official site or sites like tutorialspoint hive as a beginner.. It gets you sooo confused... Only use them after you arefortable with Android coding. CODING PHASE 1. After finishing learning from above methods you may start coding. Go make an app yourself. Note Don't go for something big like fb I too was like that and guess what? It was purely time waste! Instead go for something like recyclerview examples(avoid listview examples since they are old too). You can find many videos about that. Again just make sure the videoz are latest. 2. You will get a ton of errors! ....while running the output of above mentioned point. Don't worry. Herees StackOverflow and Quora. Ask your doubts there. There are many to help you. You will have to learn to use Stack though since it's confusing for beginners. PUBLISHING PHASE 1. Try publishing your simple apps even if it's just a Hello World! Because this publishing is the most irritating part for a developer. I tried publishing my app after 6 months of learning which was a big mistake. Because there are some rules to be taken care of in the code (especially inside file like minifyenabled and hate that part...) as well as in the publishing methods(like photo icon package name uploading CREDIT CARD CARD italic etc). So just keep on publishing from the first month itself. (Note The card used for registering in Google Play Store is usually Visa Card. But don't worry. You can use your Debit Card if its International Debit Card and convert into a Virtual Visa Card using for Tutorials. I did like that). 2. Puting ads on your think it has some work to do... I haven't done it .. So that's it. Wee to Android App Development Community my friend!

Do you mean in Android Studio?nIf yes thenn- go to Build from Toolbarn- Generate Signed Apkn- Create newn- provide any pathn- password which you can remembern- Alias - hint or alternate namen- password which you can remembern- validity - 25 yearsn- Certificate - put some general informationn- press okn- press Nextn- Apk destination folder locationn- build - for some time and your app will be in your specified location.
