当我从显示Google地图的网页视图切换到另一个视图时，我的应用程序偶尔会关闭（没有强制关闭对话框，只需关闭）。我在logcat中收到此错误：
E / libEGL（29103）：调用没有当前上下文的OpenGL ES API（每个线程记录一次）
有什么想法吗？
我有一个mainActivity，它为每个页面使用不同的“视图”。以下是main中要求视图的代码：
private void changeCardDisplayed(int index) {
// Log.i(DEBUG_TAG, "changeCardDisplay index is " + index);
if (mCardLayout != null){
mCardLayout.destroy();
} else {
mCardLayout = new CardLayout(this);
}
if (mMapView != null) mMapView.destroy();
mCardLayout = null;
mMapView = null;
mCardContainer.removeAllViews();
mMapsContainer.removeAllViews();
if (mWD != null) {
mAdView.makeAdRequest(mWD.cityId, mWD.iconCode);
}
System.gc();
switch (index) {
case ACCUWX.Views.CURRENT_VIEW:
mCardLayout = new CurrentView(this);
break;
case ACCUWX.Views.FORECAST_VIEW:
mCardLayout = new ForecastView(this);
break;
case ACCUWX.Views.HOURLY_VIEW:
mCardLayout = new HourlyListView(this);
break;
case ACCUWX.Views.LIFESTYLE_VIEW:
mCardLayout = new LifestyleView(this);
break;
case ACCUWX.Views.VIDEO_VIEW:
mCardLayout = new VideoView(this);
break;
case ACCUWX.Views.NEWS_VIEW:
mCardLayout = new NewsView(this);
break;
case ACCUWX.Views.MAP_VIEW:
mMapView = new MapsView(this);
break;
default: mCardLayout = new CurrentView(this);
break;
}
if (index == ACCUWX.Views.MAP_VIEW) {
mMapsContainer.addView(mMapView);
} else {
mCardContainer.addView(mCardLayout);
}
}
这是CardLayout类：
public class CardLayout extends RelativeLayout {
//XXX Constants
private static final String DEBUG_TAG = "Tablet/CardLayout";
public CardLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CardLayout(Context context) {
super(context);
}
/**
* Updates layout display with the provided WeatherData
* @param wdm
*/
public void update(WeatherData wd) {}
/**
* Tell the view to do any final cleanup
*/
public void destroy(){
// Log.i(DEBUG_TAG, "destroy");
// this.removeAllViews();
}
public int getViewType() {
return ACCUWX.CardViewTypes.get(this.getClass()) == null ? -999 : ACCUWX.CardViewTypes.get(this.getClass());
}
}
这是在此视图中加载地图的updateView方法MapsView.java：
private void updateView(){
mWebView = (WebView)findViewById(R.id.mapWebView);
mWebView.setFocusable(false);
mWebView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
Double lat = 0.0;
Double lon = 0.0;
lat = Double.parseDouble(mWd.getCurrentWeatherDataModel().lat);
lon = Double.parseDouble(mWd.getCurrentWeatherDataModel().lon);
mCenterURL = "javascript:mpSetCenter(" + lat + "," + lon + ")";
if (WeatherData.isWaking()) WeatherData.setWakingInMaps(true);
// Log.i(DEBUG_TAG, "centerURL is " + mCenterURL);
if (mWebView != null) {
mWebView.getSettings().setEnableSmoothTransition(true);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
String GOOGLE = "http://maps.google.com/maps?ll=" + mWd.getCurrentWeatherDataModel().lat + "," + mWd.getCurrentWeatherDataModel().lon +"&z=7&t=m";
URL urlObj;
try {
urlObj = new URL(url);
if(!(TextUtils.equals(urlObj.toString(), TERMS_OF_USE) || TextUtils.equals(urlObj.toString(), GOOGLE))){
return false;
} else if(TextUtils.equals(urlObj.toString(), GOOGLE)) {
return true;
}else if (TextUtils.equals(urlObj.toString(), TERMS_OF_USE)) {
// Open it in phone's browser rather than app's webview
if (mListener!=null)
mListener.showMapsTermsOfUse(TERMS_OF_USE);
return true;
}
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return false;
}
@Override
public void onPageFinished(WebView view, String url) {
// Log.i(DEBUG_TAG, "onPageFinished() b4 dimiss dialogs");
Dialogs.dismiss();
mHandler.removeCallbacks(mRunnable);
mHandler.postDelayed(new Runnable() {
@Override
public void run() {
if(mWebView != null) {
// Log.i(DEBUG_TAG, "run() onPageFinished");
mWebView.loadUrl(mCenterURL);
if(Utilities.isTv(mContext)) {
mWebView.loadUrl("javascript:hideMarker()");
}
}
}
}, 1000);
init();
WeatherData.setWakingInMaps(false);
}
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
// Log.i(DEBUG_TAG, "Error, oh noes! " + description);
}
});
mWebView.setWebChromeClient(new WebChromeClient() {
@Override
public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
// Log.i(DEBUG_TAG, "message in onJsAlert is " + message);
result.confirm();
return true;
}
});
if (Utilities.isTv(mContext)) {
mZoomControl = (ZoomControl) findViewById(R.id.zoom_control);
mZoomControl.setVisibility(View.VISIBLE);
mZoomControl.setOnZoomListener(mZoomListener);
mPanningControl = (PanningControl) findViewById(R.id.panning_control);
mPanningControl.setVisibility(View.VISIBLE);
mPanningControl.setPanningListener(mPanningListener);
}
String roundedTime = Utilities.roundMinutes(5);
String url = "http://vortex.accuweather.com/widget/googleMaps/maps_v3_honeycomb.html?cbt=" + roundedTime;
mWebView.loadUrl(url);
// mWebView.loadUrl("file:///android_asset/maps_v3_honeycomb.html");
Dialogs.dismiss();
// Log.i(DEBUG_TAG, "dismiss b4 this stmnt and showLoadingDialog after");
Dialogs.showLoadingDialog((android.app.Activity) mContext);
mHandler.postDelayed(mRunnable, 30000);
consumeKeyEvent(this.findViewById(R.id.mapLayout));
}
}
更新：
我有一个带有我的应用程序的预加载版本的平板电脑，当我安装当前代码时，我将此作为崩溃的原因:(如果由于预加载而更改包名称，以便我可以直接从Eclipse，应用程序没有关闭，那就是我得到那个OpenGL日志）

答案 0 :(得分：5)
这是一个已知的WebView问题。我们在上面:)请注意，此错误不会导致应用程序崩溃。你的问题出在其他地方。您还在日志中看到了什么？
