I'm trying to use react-native-maps ( link ) on an Android device compiling the example but the application It closes when I select an example, because I guess it does not get properly access Google maps. If I try from the emulator the map is not shown, since it does not have Google services installed, but it does not close. I have tried to use my API KEY and it does not work either. I'm testing it since version 5.1.1.
Hello you must create the KEY API key and then register it in the google console to create the key you must enter from the console to the next route C: \ Program Files \ Java \ jdk1.8.0_60 \ bin
and then run
keytool -genkey -v -keyalg RSA -sigalg SHA1withRSA -keystore "%USERPROFILE%\.android\debug.keystore" -storepass android -alias androiddebugkey -keypass android -dname "CN=Android Debug,O=Android,C=CO"
You must validate that the file "% USERPROFILE% .android \ debug.keystore" does not exist in that route
then run
keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
Copy the SHA1 key and paste it into the google console
and follow the instructions of react-native-maps for installation
Greetings I hope this helps you.
