[Ask] How to use Google Play App Signing in Debug about svgomg-twa

[andreban]

When using App Signing, Google Play will not provide you with the certificate used to sign the final APK, so you won't be able to use it for debugging.

One alternative would be to modify your assetstatements.json file to contain both the fingerprint used by the Play Store and the one for your debug key.

The sha256_cert_fingerprints is an array and you could do something like used here.

@andreban it works, thanks

Great to hear that! Maybe it's worth asking / replying on StackOverflow, as it would help others with the same questions to find it. We have a tag for TWAs. Let me know if you'd like to post the question and answer.

Hi,
Is it possible to post the solution here? The website link is down.
Should I just use both keys in sha256_cert_fingerprints or make another relation object as in linking for multiple apps?

You should make multiple relation objects, for example my assetlinks.json file is:

[{
  "relation": ["delegate_permission/common.handle_all_urls"],
  "target": {
    "namespace": "android_app",
    "package_name": "dev.conn.drink",
    "sha256_cert_fingerprints": [
      "8C:18:7D:26:05:EE:2E:AF:4B:76:20:6F:39:7B:04:13:91:A2:E2:EC:C4:43:04:E1:25:E8:B8:E0:F4:73:5F:80"
    ]
  }
},
{
  "relation": ["delegate_permission/common.handle_all_urls"],
  "target": {
    "namespace": "android_app",
    "package_name": "dev.conn.drink",
    "sha256_cert_fingerprints": [
      "73:9E:C8:99:79:F1:A3:7F:12:95:54:D8:A5:8E:BB:8B:BB:52:76:15:F8:FC:CB:10:D5:E4:44:89:BD:4B:8E:3A"
    ]
  }
},
{
  "relation": ["delegate_permission/common.handle_all_urls"],
  "target": {
    "namespace": "android_app",
    "package_name": "dev.conn.drink",
    "sha256_cert_fingerprints": [
      "3B:C3:C4:34:CB:E5:96:62:FF:D7:3B:19:65:64:1A:E3:AF:DF:67:FE:E9:43:34:22:DE:72:E9:BE:D9:26:DA:3A"
    ]
  }
}]
