我的问题是一样的，因为我也把我的谷歌地图项目从Eclipse转移到Android Studio。我是这样解决我的问题的:

通过以下命令进入Java bin目录:

C:\Program Files\Java\jdk1.7.0_71\bin>

现在在命令窗口(CMD.EXE)中输入以下命令:

keytool -list -v -keystore c:\users\your_user_name\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android

例子:

keytool -list -v -keystore c:\users\James\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android

如果你不知道用户名，你也可以在cmd下写:

keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

你会得到SHA1。

然后我从https://code.google.com/apis/console创建了一个新密钥，因为我的包名称已经更改，然后在我的应用程序中使用这个密钥。它工作得很好。

确保您在jdkX.X的BIN文件夹中。X_XX(我的文件夹名称是jdk1.7.0_71)，或者如果您不知道您的文件夹名称，那么可以通过打开Java文件夹找到它，您将看到文件夹名称，但您必须在BIN文件夹中，然后运行此命令。今天，我通过上述程序在cmd命令窗口中获得了我的SHA1值。

快照:

获取生产密钥库的SHA1:

Build --> Generate Signed APK... Create keystore with password and follow the steps Go to your Mac/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home/bin and drag the bin folder to the terminal after cd command to point at it so you can use the keytool tool. So, in terminal write cd (drag bin here) then press enter. Then, copy and paste this in the terminal: keytool -exportcert -alias Your_keystore_AliasName -keystore /Users/Home/Development/AndroidStudioProjects/YoutubeApp/app/YoutubeApp_keystore.jks -list -v Erase my path and go where you stored your keystore and drag your keystone and drop it after -keystore in the command line so the path will get created. Also, erase Your_keystore_AliaseName to put your alias keystone name that you used when you created it. Press Enter and enter the password :) When you enter the password, the terminal won't show that it receives keyboard entries, but it actually does, so put the password and press Enter even if you don't see the password is typed out.

我发现了一个非常简单的过程来找到你的MD5, SHA-1指纹使用 Android工作室。 运行你的项目 转到Gradle菜单(菜单:视图->工具窗口-> Gradle) 转到Gradle窗口的signingReport。(你的项目->任务-> android -> signingReport) 运行它。(使用双击或Ctrl + Shift + F10) 在运行窗口，你会发现所有的信息。

它只适用于调试模式。在释放模式下，我看不到sha-1。 这里是gradlew signingReport的结果

所以我必须使用keytool来获取sha-1。下面是Firebase官方文档:

Get_sha-1_for_release

简单，在你的启动屏幕中调用这个方法:hash()和getCertificateSHA1Fingerprint()，然后键将在日志中可见

private void hash() {


            PackageInfo info;
            try {

                info = getPackageManager().getPackageInfo(
                        this.getPackageName(), PackageManager.GET_SIGNATURES);

                for (android.content.pm.Signature signature : info.signatures) {
                    MessageDigest md;
                    md = MessageDigest.getInstance("SHA");
                    md.update(signature.toByteArray());
                    Log.e("sagar sha key", md.toString());
                    String something = new String(Base64.encode(md.digest(), 0));
                    Log.e("sagar Hash key", something);
                    System.out.println("Hash key" + something);
                }

            } catch (PackageManager.NameNotFoundException e1) {
                Log.e("name not found", e1.toString());
            } catch (NoSuchAlgorithmException e) {
                Log.e("no such an algorithm", e.toString());
            } catch (Exception e) {
                Log.e("exception", e.toString());
            }
        }

        private void getCertificateSHA1Fingerprint() {
            PackageManager pm = this.getPackageManager();
            String packageName = this.getPackageName();
            int flags = PackageManager.GET_SIGNATURES;
            PackageInfo packageInfo = null;
            try {
                packageInfo = pm.getPackageInfo(packageName, flags);
            } catch (PackageManager.NameNotFoundException e) {
                e.printStackTrace();
            }
            Signature[] signatures = packageInfo.signatures;
            byte[] cert = signatures[0].toByteArray();
            InputStream input = new ByteArrayInputStream(cert);
            CertificateFactory cf = null;
            try {
                cf = CertificateFactory.getInstance("X509");
            } catch (CertificateException e) {
                e.printStackTrace();
            }
            X509Certificate c = null;
            try {
                c = (X509Certificate) cf.generateCertificate(input);
            } catch (CertificateException e) {
                e.printStackTrace();
            }
            String hexString = "";
            try {
                MessageDigest md = MessageDigest.getInstance("SHA1");
                byte[] publicKey = md.digest(c.getEncoded());
                Log.e("sagar SHA",byte2HexFormatted(publicKey));
            } catch (NoSuchAlgorithmException e1) {
                e1.printStackTrace();
            } catch (CertificateEncodingException e) {
                e.printStackTrace();
            }
        }

        public static String byte2HexFormatted(byte[] arr) {
            StringBuilder str = new StringBuilder(arr.length * 2);
            for (int i = 0; i < arr.length; i++) {
                String h = Integer.toHexString(arr[i]);
                int l = h.length();
                if (l == 1) h = "0" + h;
                if (l > 2) h = h.substring(l - 2, l);
                str.append(h.toUpperCase());
                if (i < (arr.length - 1)) str.append(':');
            }
            return str.toString();
        }

谢谢你！

我是这样做的:

步骤1:进入这个文件夹

On Mac: /Users/<username>/.android/

On Windows: C:\Documents and Settings\<username>\.android\

On Linux: ~/.android/

第二步:运行命令行:

keytool -list -v -keystore debug.keystore -storepass android

您将看到SHA-1密钥。

当创建一个新的“谷歌地图项目”时，在Android Studio V 1.5.1中，最后一个屏幕会打开google_maps_api.xml文件，并显示如下说明的屏幕:

资源:

TODO: Before you run your application, you need a Google Maps API key. To get one, follow this link, follow the directions and press "Create" at the end: https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend&keyType=CLIENT_SIDE_ANDROID&r= YOUR SHA-1 + YOUR PACKAGE NAME You can also add your credentials to an existing key, using this line: YOUR SHA-1:YOUR PACKAGE NAME Alternatively, follow the directions here: https://developers.google.com/maps/documentation/android/start#get-key Once you have your key (it starts with "AIza"), replace the "google_maps_key" string in this file. <string name="google_maps_key" templateMergeStrategy="preserve" translatable="false">YOUR GOOGLE MAPS KEY</string>

要获得您的谷歌MAPS KEY，只需剪切并粘贴URL链接到您的浏览器中，并在创建新应用程序时遵循上面的说明。SHA-1和Package名称已经在给出的链接中，所以您不需要知道它们。然而，它们将在您的项目中的资源>Values>google_maps_api.xml文件中，当您按照创建项目的说明完成时。
