Android The getRecordDriverInfo method callback is 0. (Android)

FMOD Engine

In the record example, the getRecordNumDrivers method always returns numDrivers as 0, and the solution. (Android)

Some functionality inside of FMOD will require you set relevant permissions in your AndroidManifest.xml file.

  • Recording - to make use of the System::recordStart API use android.permission.RECORD_AUDIO.

Also the Audio Track output mode currently does not support recording, please use the OpenSL output mode for this.

I have configured the permissions required for the record example, but the number of test microphone devices is still 0.

System ->setOutput(FMOD_OUTPUTTYPE_OPENSL) has been set.

Make sure system->setOutput is called before system->init otherwise it will not do anything. You can confirm that it has worked by calling system->getOutput.
