New Users: Before you can start using the Google Maps Platform APIs and SDKs, you must sign up and create a billing account. To learn more, see Get Started with Google Maps Platform. To use the Places SDK for Android, you must have an API key. The API key is a unique identifier that is used to authenticate requests associated with your project for usage and billing purposes. Oct 13, 2017  As of Android Studio 2.2, SHA-1 fingerprint can be obtained from inside the IDE itself. The most common way developers use to find the fingerprint is shooting up. Jan 18, 2018  If you use react-native run-android: debug key hash will be used. If you use./gradlew assembleRelease and install app-release.apk: release key hash will be used. So, when you run keytool -exportcert -alias androiddebugkey -keystore /.android/debug.keystore openssl sha1 -binary openssl base64 you will see debug key hash. Nov 02, 2016  The most simplified way to build an APK in Android Studio is go to “Build” menu at top of android studio and choose “Build APK”. There are many other ways to build an apk in Android Studio in case you want to run APK in emulator/device also.

In this tutorial, we will learn to create a hashing application. User can enter some text into the edit textbox,

then click the button. The application will show the hash values generated from different hash functions,

including MD5, SHA1, SHA256, SHA384 and SHA512. The application can also compare the equality of two

messages by using hash values generated by SHA-256.

This lab will illustrate all the major hash function have been used in real world recently. The function has been

implemented are MD5, SHA-1, SHA-256, SHA-384, SHA-512. Second part of this lab is to compare the SHA-256

hash value for two input messages to determine whether these two messages are same or not.

Click 'compare' button, we will go in to compare page. If we input two different messages and compare them, we will get the following

result:

Input two same messages and compare them.

The MD5 or SHA1 signature of a Xamarin.Android app depends on the.keystore file that was used to sign the APK. Typically, a debugbuild will use a different .keystore file than a release build.

Android Studio Generate Apk With Key Hash Recipe

For Debug / Non-Custom Signed Builds

Xamarin.Android signs all debug builds with the same debug.keystorefile. This file is generated when Xamarin.Android is firstinstalled.The steps below detail the process for finding the MD5 orSHA1 signature of the default Xamarin.Android debug.keystore file.

Locate the Xamarin debug.keystore file that is used to sign theapp. By default, the keystore that is used to sign debug versions ofa Xamarin.Android application can be found at the followinglocation:

C:UsersUSERNAMEAppDataLocalXamarinMono for Androiddebug.keystore

Information about a keystore is obtained by running the keytool.execommand from the JDK. This tool is typically found in the following location:

C:Program Files (x86)JavajdkVERSIONbinkeytool.exe

Add the directory containing keytool.exe to the PATH environment variable.Open a Command Prompt and run keytool.exe using the following command:

When run, keytool.exe should output the following text. The MD5: and SHA1: labels identify the respective signatures:

Locate the Xamarin debug.keystore file that is used to sign theapp. By default, the keystore that is used to sign debug versions ofa Xamarin.Android application can be found at the followinglocation:

~/.local/share/Xamarin/Mono for Android/debug.keystore

Information about a keystore is obtained by running the keytoolcommand from the JDK. This tool is typically found in the followinglocation:

/System/Library/Java/JavaVirtualMachines/VERSION.jdk/Contents/Home/bin/keytool

Add the directory containing keytool to the PATH environment variable.Open a Terminal and run keytoolby using the following command:

When run, keytool should output the following text. The MD5: and SHA1: labels identify the respective signatures:

For Release / Custom Signed Builds

The process for release builds that are signed with a custom.keystore file are the same as above, with the release.keystore file replacing the debug.keystore file that is usedby Xamarin.Android. Replace your own values for the keystore password,and alias name from when the release keystore file was created.

When the Visual Studio Distributewizard is used to sign a Xamarin.Android app, the resulting keystore resides in the following location:

C:UsersUSERNAMEAppDataLocalXamarinMono for AndroidKeystorealiasalias.keystore

For example, if you followed the steps in Create a New Certificate to create a new signing key, the resulting example keystore resides in the following location:

C:UsersUSERNAMEAppDataLocalXamarinMono for AndroidKeystorechimpchimp.keystore

When the Visual Studio for Mac Sign and Distribute..wizard to sign your app, the resulting keystore resides in the following location:

For example, if you followed the steps in Create a New Certificate to create a new signing key, the resulting example keystore resides in the following location:
