Ensure that the “Google Maps Android API v2” is en

问题:

I am working on google maps and I am getting this error. I had done the following things:

1. Got My sha1 fingerprint.

2. Registered my project and got my project key.

I don't know to how to get Google Maps Android API v2 enable because all the links I have tried are old and Google had changed it's site design. Please help me. I already have wasted a lot of time on this.

My Logcat:

Authorization failure.  Please see developers.google.com/maps/documentation/android-api/start for how to correctly set up the map.
E/Google Maps Android API: In the Google Developer Console (console.developers.google.com)


 Ensure that the "Google Maps Android API v2" is enabled.
 Ensure that the following Android Key exists:
   API Key: AIzaSyBK8rKr9lCRLhzv68I4Q26G9pHHO******

From error it is clear that You did not enable google map api for android. To enable,

1. Login google developer console
2. Select Library option from left side panel.
3. Now you can see all API list and go to Google Maps APIs and select Google Maps Android API .
4. Now you can see option to enable/disable API. Enable it.

I hope it help you.

Google Developer Console

1. Login to Developer Console.
2. In your Dashboard Navigation Menu.(left side)
3. Select API & Services > Credentials.
4. So you will be redirected to Credentials page were you can view all the API keys that you created (https://console.cloud.google.com/apis/credentials)
5. Identify your Project API key and click on Edit Api Key.
6. Under that you can see the Key restrictions
7. From there remover all Application restrictions and Api restriction.

On your Android Mobile

Android Studio

This steps worked for me perfectly.

I had the same problem, but in the following setup:

My actual developing took place on a Windows machine. Then I bought a Mac and figured I'd develop on it. I installed Android Studio on my Mac, checked out my project from Github, then attempted a run of it using my Android phone. The APK installation carried out seamlessly. However, once the application launched on the phone, the GoogleMap wouldn't display, even though the rest of my app was functioning normally. Then I found this link => https://github.com/react-community/react-native-maps/issues/69, went to my console.developers.google.com/ and opened my Google Maps key that I had issue with.

What I saw was that the key was restricted to Android apps. But I was working on an Android app, how could this be the issue? Anyhow, I switched Key Restriction to None, reran my app, and GoogleMap loaded just as it should had.

This may happen when the package name is incorrect in the console credential section for development and production make sure your package name is correct. In my case, the package name was wrong when I corrected it map become visible

回答5:

you may need to add new SHA-1 Certificate fingerprints to your API key application restrictions page:

to generate a SHA1 Certificate fingerprints for your debug build, use keytool of java jre as the following example command:

C:\Program Files\Android\Android Studio\jre\bin>keytool -list -v -keystore C:\Users\linhd\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android

I added a key from another test project to a main. Then I opened https://console.developers.google.com/ and added that key with a new application name (like Linh Dao wrote), but it didn't help.

Then I added a new activity (a template "Google Maps Activity" in a gallery) and opened a file google_maps_api.xml. From there I again found a link like https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend&keyType=CLIENT_SIDE_ANDROID&r=06:F2:F4:CD...applicationName.

I opened app/build.gradle, found applicationId value with applicationIdSuffix, if exists, and joined, for instance into com.example.myapp.debug. In the link I changed an applicationName to this new value and opened the link.

Again created a new project, generated a new key and edited it, wrote package name and SHA-1 fingerprint, like @Linh Dao wrote. Then saved. If you later with to find that key, find your project in Google console and open credentials.

I deleted an unnecessary map activity and in AndroidManifest retained

<meta-data
    android:name="com.google.android.geo.API_KEY"
    android:value="@string/google_maps_key" />

in application tag.
