如果你使用React Native，调试。Keystore在android/app中，但可能不在~/.android中。

设置调试。Keystore路径如下:

keytool -list -v -keystore {PROJECT_ROOT}/android/app/debug.keystore -alias androiddebugkey -storepass android -keypass android

控制台将打印如下内容:

Alias name: androiddebugkey
Creation date: Jan 1, 2014
Entry type: PrivateKeyEntry
Certificate chain length: 1
Certificate[1]:
Owner: CN=Android Debug, OU=Android, O=Unknown, L=Unknown, ST=Unknown, C=US
Issuer: CN=Android Debug, OU=Android, O=Unknown, L=Unknown, ST=Unknown, C=US
Serial number: 2==Serial Number==2
Valid from: Wed Jan 01 06:35:04 CST 2014 until: Wed May 01 06:35:04 CST 2052
Certificate fingerprints:
     SHA1: 5E:=========== SHA1 SIGNING KEY ===========:25
     SHA256: FA:============ SHA 256 ===================9C
Signature algorithm name: SHA1withRSA
Subject Public Key Algorithm: 2048-bit RSA key
Version: 3

你可以通过去Window>Preference>Android>Build in Eclipse获取任何工作区的MD5和SHA1指纹。

我使用的是Ubuntu 12.0.4，我已经通过这种方式在命令提示符上获得了发布密钥存储的证书指纹 在生成keystore文件后，你可以使用这个密钥发布应用程序，如果你在你的应用程序中使用谷歌映射，这样可以在发布后在应用程序中正确显示映射，我在下面的命令提示符中得到了结果

administrator@user:~$ keytool -list -v -keystore /home/administrator/mykeystore/mykeystore.jks -alias myprojectalias Enter keystore password: ****** Alias name: myprojectalias Creation date: 22 Apr, 2014 Entry type: PrivateKeyEntry Certificate chain length: 1 Certificate[1]: Owner: CN=xyz, OU= xyz, O= xyz, L= xyz, ST= xyz, C=91 Issuer: CN= xyz, OU= xyz, O= xyz, L= xyz, ST= xyz, C=91 Serial number: 7c4rwrfdff Valid from: Fri Apr 22 11:59:55 IST 2014 until: Tue Apr 14 11:59:55 IST 2039 Certificate fingerprints: MD5: 95:A2:4B:3A:0D:40:23:FF:F1:F3:45:26:F5:1C:CE:86 SHA1: DF:95:Y6:7B:D7:0C:CD:25:04:11:54:FA:40:A7:1F:C5:44:94:AB:90 SHA276: 00:7E:B6:EC:55:2D:C6:C9:43:EE:8A:42:BB:5E:14:BB:33:FD:A4:A8:B8:5C:2A:DE:65:5C:A3:FE:C0:14:A8:02 Signature algorithm name: SHA276withRSA Version: 2 Extensions: ObjectId: 2.6.28.14 Criticality=false SubjectKeyIdentifier [ KeyIdentifier [ 0000: 1E A1 57 F2 81 AR 57 D6 AC 54 65 89 E0 77 65 D9 ..W...Q..Tb..W6. 0010: 3B 38 9C E1

在Windows平台上，我们可以使用下面的方法获取调试模式的密钥库

C:\Program Files\Java\jdk1.8.0_102\bin>keytool -l .android\debug.keystore -alias androiddebugkey -s id Alias name: androiddebugkey Creation date: Oct 21, 2016 Entry type: PrivateKeyEntry Certificate chain length: 1 Certificate[1]: Owner: C=US, O=Android, CN=Android Debug Issuer: C=US, O=Android, CN=Android Debug Serial number: 1 Valid from: Fri Oct 21 00:50:00 IST 2016 until: S Certificate fingerprints: MD5: 86:E3:2E:D7:0E:22:D6:23:2E:D8:E7:E SHA1: B4:6F:BE:13:AA:FF:E5:AB:58:20:A9:B SHA256: 15:88:E2:1E:42:6F:61:72:02:44:68 56:49:4C:32:D6:17:34:A6:7B:A5:A6 Signature algorithm name: SHA1withRSA

在最近更新的Android Studio 4.2中，我们无法获得文件:signing report。所以，我们可以通过以下步骤再次得到这个结果:

File -> Settings -> Experimental -> 
Now we need to uncheck the *do not build Gradle list during Gradle sync* ->
Click Ok -> now again go to File -> Click on *Sync Project with Gradle files*

现在你可以理解其他答案的意思了。

感谢@PapayaCoders Youtube频道解决了这个问题。这里是关于这个问题的视频链接。

如果你正在使用Android Studio IDE，那么你可以得到SHA1有价值的所有构建变体，只需点击一下。

在Gradle Projects窗口>选择根项目> signingReport >双击

Next

转到变体:发布为发布

转到变体:调试调试

[![更改构建变量，然后您可以看到应用程序的运行，这将导致错误

你必须找到释放密钥的SHA1代码，并在开发人员控制台输入它。(对我来说，开发人员控制台是firebase，有些人可能使用不同的服务)找到SHA1代码。简单的方法是

Go to Build --- Select Build Variant -- On the left Side Select "Release" as build variant -- now go to module settings ( or try to run project , android studio will tell you about a error and click fix error button) --- Select Signing tab --- add your release key and passwords -- now goto build types -- select release -- on signing config select your release key config -- now run your project -- now run your signing report --- you can find SHA1 under release build -- enter that sha1 code on your developer console
