Hi guys, I installed the SDK on my app, so in the first place I added the initialize code on my app component like the demo, I created a instant meeting successfully and invited a friend to test it, everything worked like expected until I clicked the end button, the app was reloaded and the initialization was done again and it got stuck so my app showed a blank screen indefinitively, not exception shown. I changed the initialization code to other custom component so when I end the meeting the app realoads and go back to home screen like I expected but if I try to go to this component again I get a exception: ``` Wait................................ ``` V/\<------- ZoomCordovaPlugin ----------\>: _ **onZoomSDKLoginResult** _ result =====0 W/cr\_AwContents: Application attempted to call on a destroyed WebView java.lang.Throwable at org.chromium.android\_webview.AwContents.a(PG:378) at org.chromium.android\_webview.AwContents.a(PG:707) at com.android.webview.chromium.WebViewChromium.evaluateJavaScript(PG:288) at android.webkit.WebView.evaluateJavascript(WebView.java:977) at com.getcapacitor.cordova.MockCordovaWebViewImpl$CapacitorEvalBridgeMode$1.run(MockCordovaWebViewImpl.java:80) at android.app.Activity.runOnUiThread(Activity.java:5815) at com.getcapacitor.cordova.MockCordovaWebViewImpl$CapacitorEvalBridgeMode.onNativeToJsMessageAvailable(MockCordovaWebViewImpl.java:76) at org.apache.cordova.NativeToJsMessageQueue.enqueueMessage(NativeToJsMessageQueue.java:249) at org.apache.cordova.NativeToJsMessageQueue.addPluginResult(NativeToJsMessageQueue.java:238) at com.getcapacitor.cordova.MockCordovaWebViewImpl.sendPluginResult(MockCordovaWebViewImpl.java:253) at org.apache.cordova.CallbackContext.sendPluginResult(CallbackContext.java:61) at cordova.plugin.zoom.Zoom.onZoomSDKLoginResult(Zoom.java:749) at us.zoom.sdk.ZoomSDK.onSDKLoginReturn(ZoomSDK.java:844) at us.zoom.sdk.ZoomSDK.access$100(ZoomSDK.java:49) at us.zoom.sdk.ZoomSDK$2.onPTAppEvent(ZoomSDK.java:107) at com.zipow.videobox.ptapp.PTUI.dispatchPTAppEventImpl(PTUI.java:769) at com.zipow.videobox.ptapp.PTUI.dispatchPTAppEvent(PTUI.java:707) at com.zipow.videobox.mainboard.Mainboard.heartBeat4SingleProcessImpl(Native Method) at com.zipow.videobox.mainboard.Mainboard.heartBeatForSDK(Mainboard.java:999) at com.zipow.videobox.ptapp.PTApp.dispatchIdleMessage(PTApp.java:341) at com.zipow.videobox.VideoBoxApplication$5.run(VideoBoxApplication.java:1202) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:145) at android.app.ActivityThread.main(ActivityThread.java:7007) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1404) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1199) can anyone help me? ---

Hi [kevin.camplone](https://devforum.zoom.us/u/kevin.camplone), Thanks for using Zoom SDK. If you have successfully initialized the SDK, you do not need to initialize several times. Please try only to initialize the SDK once. Thanks! ---

Hi carson! Thanks for your response, i initialize once in my app component, but when i click the end meeting button the app is reloaded so the initialization code is executed again. Its weird. ---

Hi again, Let me explain myself again, the initialization code is in my app.component.ts so every time the app is closed or reloaded it got executed. that’s the problem. I don’t know why but when the user end/quit the meeting, the app is reloaded so the app.component.ts is called again. I fixed it adding this code in Zoom.java: if (!this.mZoomSDK.isInitialized()) { this.initialize(appKey, appSecret, callbackContext); } I think this ionic sdk should have the method isInitialized() thanks! ---

Hi [kevin.camplone](https://devforum.zoom.us/u/kevin.camplone), Thanks for the reply and the info. I was not able to reproduce the second initialization on my end, I only experience the initialization once, however, I totally agree that enhancement you are suggesting. I will forward this info to the engineering team. Thanks! ---
