要在Android的WebView中启用摄像头和麦克风,你需要使用以下步骤:
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setMediaPlaybackRequiresUserGesture(false);
webView.getSettings().setAllowContentAccess(true);
webView.getSettings().setDomStorageEnabled(true);
webView.setWebViewClient(new WebViewClient() {
@Override
public void onPermissionRequest(final PermissionRequest request) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
request.grant(request.getResources());
}
}
});
private static final int PERMISSION_REQUEST_CODE = 1;
private void requestPermissions() {
String[] permissions = {Manifest.permission.CAMERA, Manifest.permission.RECORD_AUDIO};
if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED
|| ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, permissions, PERMISSION_REQUEST_CODE);
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == PERMISSION_REQUEST_CODE) {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED
&& grantResults[1] == PackageManager.PERMISSION_GRANTED) {
// 权限已授予
} else {
// 权限被拒绝
}
}
}
通过按照上述步骤,你应该能够在Android的WebView中启用摄像头和麦克风,并进行会议。
