​Set Up Device for Development

​​
​​This article will discuss how to setup an Android device and connect it to a computer so that the device may be used to run and debug Xamarin.Android applications.
​​By now, you've probably seen your great new application running on the Android emulator, and want to see it running on your shiny Android device. Here are the steps involved with connecting a device to a computer for debugging:
​​
  1. ​​Enable Debugging on the Device - By default, it will not be possible to debug applications on a Android device.
  1. ​​Install USB Drivers - This step is not necessary for OS X computers. Windows computers may require the installation of USB drivers.
  1. ​​Connect the Device to the Computer - The final step involves connecting the device to the computer by either USB or WiFi.
​​
​​Enable Debugging on the Device
​​It is possible to use any Android device to test an Android application. However the device must be properly configured before debugging can occur. The steps involved are slightly different, depending on the version of Android running on the device.
​​Android 4.0 to Android 4.1
​​
​​For Android 4.0.x to Android 4.1.x, debugging is enabled by following these steps:
  1. ​​Go to the Settings screen.
  1. ​​Select Developer options .
  1. ​​Check off the USB debugging option.
​​
​​This screenshot shows the Developer options screen on a device running Android 4.0.3:
​​
​​Android 4.2 and higher tell 7.2
​​Starting in Android 4.2 and higher, the Developer options is hidden by default. To make it available, go to Settings > About phone, and tap the Build number item seven times to reveal the Developer Options tab:
​​
​​
​​Once the Developer Options tab is available under Settings > System, open it to reveal developer settings:
​​
​​
​​Install USB Drivers
​​This step is not necessary for OS X. Just connect the device to the the Mac with a USB cable.
​​It may be necessary to install some extra drivers before a Windows computer will recognize an Android device connected by USB.
​​
​​Note: These are the steps to set up a Google Nexus device and are provided as a reference. Steps for your specific device may vary, but will follow a similar pattern. Search the internet for your device if you have trouble.
​​
​​Download the USB Drivers
​​Google Nexus devices (with the exception of the Galaxy Nexus) require the Google USB Driver. The driver for the Galaxy Nexus is distributed by Samsung. 
​​
​​All other Android devices should use the USB driver from their respective manufacturer.
​​Install the Google USB Driver package by starting the Android SDK Manager, and expanding the Extras folder, as can be seen in the follow screenshot:
​​
​​Check the Google USB Driver box, and click the Install button. 
​​
​​Connect the Device to the Computer
​​The final step is to connect the device to the computer. There are two ways to do so:
  • ​​USB cable - This is the easiest and most common way. Just plug the USB cable into the device and then into the computer.
  • ​​WiFi - It is possible to connect an Android device to a computer without using a USB cable, over WiFi. This technique requires a bit more effort but could be useful when there is no USB cable or the device is to far away for a USB cable. Connecting via WiFi will be covered Here.
​​
​​Now Your device will appear in the Debug section click start and the application will be deployed to your own device.
​​
​​Now you can start you own test
​​

​
​Publishing Application

​​
​​Before starting the archive process be sure to change the application package name from the AndroidManifest.xml file as bellow to your own package name  as ex: com.websitename.Timeline
​​
​​The following screenshot is how your configuration should be before the archive process 
​​1-Red color are very important
​​2-Orange color reduces the APK size (Leave it as default if you are not a developer)
​​3-Green Is optional when selecting AOT and Enable Startup Tracing the splash screen will be loading faster 50% but the app size will increase as well 25% so its your choice and its up to you.
​​
​​ 
​​To reduce the app size and make the APK less  please read the Article Here
​​
​
​1 - Archive for Publishing
​​To begin the publishing process, right-click the project in Solution Explorer and select the Archive... context menu item:
​​Archive... launches the Archive Manager and begins the process of archiving the App bundle as shown in this screenshot:
​​
​​
​
​2 - Distribution:
​​When an archived version of the application is ready to publish, select the archive in the Archive Manager and click the Distribute... button:
​​
​​The Distribution Channel dialog presented two choices for distribution. Select Ad-Hoc:
​​
​​Create a New Certificate
​​After Ad-Hoc is selected, Visual Studio opens the Signing Identity page of the dialog as shown in the next screenshot. To publish the .APK, it must first be signed with a signing key (also referred to as a certificate). An existing certificate can be used by clicking the Import button and then proceeding to Sign the APK. Otherwise, click the click the + button to create a new certificate:
​​
​​The Create Android Key Store dialog is displayed; use this dialog to create a new signing certificate that can use for signing Android applications. Enter the required information (outlined in red) as shown in this dialog:
​​
​​The resulting keystore resides in the following location: (Save Them)
​​(C:\Users\USERNAME\AppData\Local\Xamarin\Mono for Android\alias\alias.keystore)
​​For example, the above steps might create a new signing key in the following location:
​​(C:\Users\USERNAME\AppData\Local\Xamarin\Mono for Android\chimp\chimp.keystore)
​​
​​Sign the APK
​​When Create is clicked, a new key store (containing a new certificate) will be saved and listed under Signing Identity as shown in the next screenshot. To publish an app on Google Play, click Cancel and go to Part 3. To publish ad-hoc, select the signing identity to use for signing and click Save As to publish the app for independent distribution. For example, the chimp signing identity (created earlier) is selected in this screenshot:
​​
​​Next, the Archive Manager displays the publishing progress. When the publishing process completes, the Save As dialog opens to ask for a location where the generated .APK file is to be stored:
​​
​​Navigate to the desired location and click Save. If the key password is unknown, the Signing Password dialog will appear to prompt for the password for the selected certificate:
​​
​​Now you are ready to submit your application to Google Play
​​
​​
​
​3 - SHA-1 fingerprint ?
​​To Display your SHA-1 Key You can double click on the Signing identity name on your dialog and copy the SHA-1 key hash where you can use it for Google maps integration or for social logins
​​

​
​4 - Reduce the APK size

​​Users often avoid downloading apps that seem too large, This article describes how to reduce your APK size, which enables more users to download your app.
​​
​​Step 1 Follow the picture bellow and your Android option should be same as the image bellow 
​​Dont select the green color frame leave it unchecked 
​​
​​After selecting Generate Package Per ABI and after archive process is done open your Installed APK folder and you will see as bellow 
​​
​​Now Your APK is about 36 MB without the Google compressor once you submit it to the google play console it will be 25 MB  till 30 MB.
​​
​​Step 2 Still you want Smaller ? ​😉​ 
​​After you open your archive folder you will see the following archives if you selected (Generate Package Per ABI)
​​
​​Usually you submit the red framed archive as the image bellow which is 36MB
​​instead of submitting it you can submit 2 APKs to google play by uploading the Archives which are pointed by the red arrow which are 28MB size.
​​
​​
​​Now your APK file will be from 20 to 25 MB in Google play
​​

​
​5-Improving Startup Times (Splash Screen Loading)

​​If you use AOT today, it improves startup times drastically, but you suffer in APK size bloat. This, unfortunately, is not a bargain that most Android applications can take in this modern-day as we must keep our users at the forefront of our decisions. They also ensure that they don’t have to download a large APK just to use our services. There must be a better way forward we thought.
​​
​​We wanted to make sure we address this problem head-on by giving you the best of both worlds; a Performance startup experience, and minimal increase to APK size.
​​Starting today, we’re announcing faster starter times using Startup Tracing on Android for all versions of Visual Studio 2019.
​​
​
​What is Android AOT?
​​The Android runtime(ART) is a managed runtime used by applications and system services on Android. ART as the runtime executes Dalvik Executables (.dex files – Dalvik EXecutable) which is a compact format to store Dalvik bytecode.
​​ART introduced the use of ahead-of-time (AOT) compilation by compiling entire applications into native machine code upon the installation of the application. This brings faster execution of applications and improved memory allocation. As well as garbage collection mechanisms, more accurate profiling, and much more.
​​To accomplish this, ART uses a utility known as dex2oat​ (Dalvik Executable to Of Ahead Time) to create an ELF (Executable and Linkable Format) executable. The downside requires additional time to compile. Additionally, applications take up larger amounts of disk memory to store the compiled code.
​​
​
​What is Startup Tracing?
​​Mono introduced a feature which allows one to use a built-in AOT profiler on an application to generate an AOT profile. The profiler conducts memory profiling, execution time profiling, and even a statistical-based sampling for profiling. This generates an AOT profile that can be used to optimize your application when using Mono’s AOT feature with a profile.

​​Type Build
​​Startup Speed
​​APK Size (Without ABI )

​​If you use AOT today, it improves startup times drastically, but you suffer in APK size bloat. This, unfortunately, is not a bargain that most Android applications can take in this modern-day as we must keep our users at the forefront of our decisions. They also ensure that they don’t have to download a large APK just to use our services. There must be a better way forward we thought.
​​
​​We wanted to make sure we address this problem head-on by giving you the best of both worlds; a Performance startup experience, and minimal increase to APK size.
​​Starting today, we’re announcing faster starter times using Startup Tracing on Android for all versions of Visual Studio 2019.

​
​What is Android AOT?
​​The Android runtime(ART) is a managed runtime used by applications and system services on Android. ART as the runtime executes Dalvik Executables (.dex files – Dalvik EXecutable) which is a compact format to store Dalvik bytecode.
​​ART introduced the use of ahead-of-time (AOT) compilation by compiling entire applications into native machine code upon the installation of the application. This brings faster execution of applications and improved memory allocation. As well as garbage collection mechanisms, more accurate profiling, and much more.
​​To accomplish this, ART uses a utility known as dex2oat​ (Dalvik Executable to Of Ahead Time) to create an ELF (Executable and Linkable Format) executable. The downside requires additional time to compile. Additionally, applications take up larger amounts of disk memory to store the compiled code.

​
​What is Startup Tracing?
​​Mono introduced a feature which allows one to use a built-in AOT profiler on an application to generate an AOT profile. The profiler conducts memory profiling, execution time profiling, and even a statistical-based sampling for profiling. This generates an AOT profile that can be used to optimize your application when using Mono’s AOT feature with a profile.
