Unable to use exported function from WebAssembly module? -


the following javascript code throwing error mymathmodule.exports undefined:

<script> fetch("test.wasm")     .then(function(response) {         return response.arraybuffer();     })     .then(function(buffer) {         var modulebufferview = new uint8array(buffer);         var mymathmodule = webassembly.instantiate(modulebufferview);           for(var = 0; < 5; i++) {             console.log(mymathmodule.exports.doubleexp(i));         }     }); </script>

test.wasm exports doubleexp function.

webassembly.instantiate promise. you're trying use webassembly.instance promise returns when completes. like

fetch("test.wasm") .then(function(response) {     return response.arraybuffer(); }) .then(function(buffer) {     var modulebufferview = new uint8array(buffer);     webassembly.instantiate(modulebufferview)     .then(function(instantiated) {         const instance = instantiated.instance;         console.log(instance.exports.doubleexp(i));     }) });

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
