问题 While trying to release my app for production, the pre-launch report notified me of an error on Pixel 2 Android P Preview device. The error is related to a custom toast message I have, saying that a View "has already been added to the window manager": java.lang.IllegalStateException: View android.support.constraint.ConstraintLayout{efbeb21 V.E...... ......ID 0,0-788,1124 #7f0900db app:id/toast_correct_container} has already been added to the window manager. at android.view.WindowManagerGlobal

问题 I am creating a customised implementation of the MarkerDemo provided for GoogleMaps V2. I have a strange error whereby I am providing LatLng values to a LatLngBounds.Builder instance and then passing it as a variable with .build. When I run the app in Debug mode through Eclipse, the Map loads. When I run it normally through Eclipse, there is an IllegalStateException thrown with "no included points" as a message. Can anyone help? Here is some code to assist. public class MyActivity extends

问题 I implemented In-app Billing (v3) according to Android's Implementing In-app Billing guide. All works fine, until I rotate the device, then immediately rotate it back to it's original orientation. Actually, sometimes it works, and sometimes it crashes with: java.lang.IllegalStateException: IabHelper was disposed of, so it cannot be used. Seems this is related to the asynchronous nature of IAB, though I'm not positive. Any thoughts? 回答1: You're probably getting the exception because somewhere

问题 I know it sounds like a duplicate of FragmentStatePagerAdapter IllegalStateException: <MyFragment> is not currently in the FragmentManager but his solution isn't relevant to my case. I'm getting the following crash very rarely: java.lang.RuntimeException: Unable to pause activity {MyActivity}: ... Caused by: java.lang.IllegalStateException: Fragment MyFragment {40648258 id=0x7f070051} is not currently in the FragmentManager at android.support.v4.app.FragmentManagerImpl.putFragment(MT:516) at

问题 When running my webapp, I get the stacktrace listed below every other try. Note that there doesn't seem to be multiple ContextLoader definitions im web.xml as far as I can tell. Moreover, the app runs just fine the second/fourth/etc. time. This behaviour is much harder to debug than if it simply didn't work. Can anyone shed some light on this? java.lang.IllegalStateException: Cannot initialize context because there is already a root application context present - check whether you have

问题 I need to move Camera to cover all Markers on it. So, I build LatLngBounds and then try to call mMap.moveCamera(CameraUpdateFactory.newLatLngBounds(latLngBounds, 15)) . Problem is when I use moveCamera() method, I'm getting IllegalStateException , but when I use animateCamera() it goes just fine. I call both methods in onMapReady callback. What is going on? My stacktrace (main part): java.lang.IllegalStateException: Error using newLatLngBounds(LatLngBounds, int): Map size can't be 0. Most

问题 I'm experimenting with AudioTrack class. Basically, my app has to generate a sound when the user touches a specific object on screen. I've used this example as a guide. My app seems to work as it should but usually after touching the screen for about a minute it crashes: 07-02 20:40:53.459: E/AndroidRuntime(11973): FATAL EXCEPTION: Thread-10 07-02 20:40:53.459: E/AndroidRuntime(11973): java.lang.IllegalStateException: play() called on uninitialized AudioTrack. 07-02 20:40:53.459: E

问题 I am rarely getting this error while making an API call. java.lang.IllegalStateException: Fragment not attached to Activity I tried putting the code inside isAdded() method to check whether fragment is currently added to its activity but still i rarely gets this error. I fail to understand why I am still getting this error. How can i prevent it? Its showing error on the line- cameraInfo.setId(getResources().getString(R.string.camera_id)); Below is the sample api call that i am making. SAPI
