API level 26 - `android.js`

[FrankSpierings]

Frida Java.available will respond with false on Android API level 26. It seems that android.js does not know where the method art::IndirectReferenceTable::Add is. It can be fixed by overwriting (line 51)
'_ZN3art22IndirectReferenceTable3AddEjPNS_6mirror6ObjectE': ['art::IndirectReferenceTable::Add', 'pointer', ['pointer', 'uint', 'pointer']],
with '_ZN3art22IndirectReferenceTable3AddENS_15IRTSegmentStateENS_6ObjPtrINS_6mirror6ObjectEEE': ['art::IndirectReferenceTable::Add', 'pointer', ['pointer', 'uint', 'pointer']],.

Since I don't understand the code in this file completely, I did not issue a pull request.

The way identified the new function name is below:

modules = Process.enumerateModulesSync()
for (i in modules) {
	module = modules[i].name
	// console.log(module)
	symbols = Module.enumerateExportsSync(module)
	for (j in symbols) {
		symbol = symbols[j].name
		// console.log('\t' + symbol)
		if (symbol.match('Indirect.*Ref.*Add')) {
			console.log(module)
			console.log(symbol)
		}
	}
}
