Black screen

[migellal]

I downloaded the source, started the application 'simplemap' and I see only black screen. I don't change anything. I forget about something? Why does not work?

Confirm. At android 4.2 simplemap doesn't work. Here is what I got in logcat:

D/NativeCrypto: ssl=0x54526d00 NativeCrypto_SSL_do_handshake ret=-1 errno=0 sslError=1 timeout_millis=30000
E/NativeCrypto: Unknown error during handshake
D/NativeCrypto: ssl=0x54526d00 NativeCrypto_SSL_do_handshake unclean error => 0
I/System.out: SSL:javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x54526d00: Failure in SSL library, usually a protocol error
I/System.out: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version (external/openssl/ssl/s23_clnt.c:741 0x4ea5a898:0x00000000)

Seems like it is a bug in Android. Here's some solutions (I didn't tested it): https://stackoverflow.com/a/30302235/5992036

seem that there is no source defined.

Hi

Thanks for keeping this issue alive :D. We have not kept this repo alive with updates from tangram-es project. As a result, APIs used here are super outdated.

For immediate needs of a demo application, I would recommend referring: https://github.com/tangrams/tangram-es/tree/master/platforms/android.

We will try and get this updated with the latest release from tangram-es, but the timeline for the same is unknown. However, if anyone can get to this before, will highly appreciate the effort and request to file a PR for the same.

Thanks

There is no bubble-wrap-style.yaml in the project.
