How can we make APKs of Android apps?
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.
How do I build an APK in Android studio?
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
Is there an app I can create?
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
How do I publish an Ionic 4 app to the Google Play Store?
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.
What is the best way to make a cross platform iOS/Android app, for this situation?
How do I publish an Android app?
How do I get started with Android application development with only very basic knowledge about programming?
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!
