Android Activity Lifecycle called twice when starting new Activity
3
I am basically starting new Activity which contains a WebView. But this WebView Activity's lifecycle called twice when first run. When destroy this activity and reopen again everything works fine.
Activity A runs
Act A -> onCreate
Act A -> onStart
Act A -> onResume
Start new activity with
startActivity(new Intent(this, WebViewActivity.class));
Activity B (WebView Activity) runs
Act A -> onPause
Act B -> onCreate
Act B -> onStart
Act B -> onResume
Log info may be cause this situation
W/WindowManager: Attempted to set replacing window on non-existing app token Token{1a4a5a ActivityRecord{219a05 u0 ui.activity.WebViewActivity t130}}
then continue with
Act B -> onPause
Act B -> onStop
Act B -> onDestroy
Act B -> onCreate
Act B -> onStart
Act B -> onResume
Act A -> onStop
I have tested this situation with many devices
Xiaomi mi a2 Lite Api 27-> error happens
Lg g4 Api 24 -> error happens
Huawei Nexus 6P Api 27-> error happens
Huawei Mate 10 Lite Api 26 -> error happens
Emulator Api 21 -> error not happens
Xiomi mi a2 Api 27 -> error not happens
is it a device bug? or OS bug? How can I fix it? if anyone can help, I will be appreciate.
My WebView Activity Code
public class WebViewActivity extends BaseActivity implements ViewClickHandler {
public static final String TAG = WebViewActivity.class.getSimpleName();
public static final String URL = "https://www.google.com";

super.onCreate(savedInstanceState);
binding = DataBindingUtil.setContentView(this, R.layout.activity_web_view);
binding.setClickHandler(this);
binding.setLifecycleOwner(this);
setToolbar(binding.toolbar, true, R.string.terms_of_service);
initWebview();
binding.webView.loadUrl(URL);
Log.d(TAG, "onCreate");
}
private void initWebview() {
binding.webView.setWebViewClient(new WebViewClient(){
@Override

//Your code to do

} catch (Exception ignore) {
}
}
});

binding.webView.getSettings().setJavaScriptEnabled(true);
binding.webView.getSettings().setUseWideViewPort(true);

}

I think this problem should be related to context. You should be using the context of the Activity. it seems you instantiated webview in DataBindingUtil class with the wrong context. Please pass the context that is WebViewActivity class to your Webview
