[android-developers] post data not re-submitted on webview back in 4.4.4
Anyone run into this? Activity creates a WebView and sets cache mode = LOAD_NO_CACHE, then calls WebView.postUrl() with a URL and some POST data. The resulting webpage has a hyperlink, which the user tap to access a second page. He then taps the device back button, which I intercept and turn into a goBack() call on the WebView. On a 4.2.2 device this results in the original POST request being re-sent along with the original data supplied to WebView.postUrl(). On a 4.4.4 device the device still makes a POST request, but without the POST data. Verified this is this case by way of server logs. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Using android:action to launch activity from settings
I have defined my settings.xml file to include an item that uses
android:action item in the setting dialog. See the sample code for
that activity below.
It all works fine. However this thing is overlaying my entire
activity and when user presses back button my entire application
finishes. Is there a way to launch a Fragment using android:action
in settings.xml or how I can restructure my activity so when that
activity finishes my main activity is resumed?
PreferenceScreen
Preference android:title=Current User
intent android:action=com.example.coreui.ShowCurrentUserActivity
/
/Preference
/PreferenceScreen
here is the activity code
public class ShowCurrentUserActivity extends Activity {
public AlertDialog dialog = null;
@Override
public void onCreate(Bundle savedInstanceState) {
String msgStr;
super.onCreate(savedInstanceState);
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setPositiveButton(Logout,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();
ShowCurrentUserActivity.this.finish();
}
});
alert.setNegativeButton(Dismiss,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();
ShowCurrentUserActivity.this.finish();
}
});
}
}
This is how I specify activity in my AndroidManifest.xml
activity
android:name=com.example.coreui.ShowCurrentUserActivity
android:label=CurrentUser
android:exported=false
intent-filter
action android:name=com.example.coreui.ShowCurrentUserActivity /
category android:name=android.intent.category.DEFAULT /
/intent-filter
/activity

[android-developers] Tracking down multiple Activity instances in memory
I'm fairly sure I have been able to use the eclipse tools before to track down memory leaks - I even found one in Google Analytics. But I can't for the life of me figure out. I have found out that there are two instances of Activity B in memory when the activity is closed. I can see that with I know enough to know that that is bad. But what I cannot see is WHY. Why is that stupid activity still in memory twice? I seem to remember that I right click on something and choose Merge Path to GC Roots. Then I get something like this. Class Name | Ref. Objects | Shallow Heap | Ref. Shallow Heap | Retained Heap --- com.android.internal.policy.impl.PhoneLayoutInflater @ 0x42d2b0d8 Unknown|1 | 40 | 536 |64 '- mPrivateFactory, mContext MyActivity @ 0x42d28230|1 | 536 | 536 | 127,336 class com.android.internal.os.ZygoteInit @ 0x41a21a18 System Class |1 | 120 | 536 | 1,000 '- mResources android.content.res.Resources @ 0x41aa7108 |1 | 112 | 536 | 8,512 '- mContext android.app.ContextImpl @ 0x43009398 |1 | 128 | 536 |10,400 '- mOuterContext MyActivity @ 0x42d4f008 |1 | 536 | 536 | 3,864 --- Well that PhoneLayoutInflater shouldn't be holding on to that context of a closed activity, but I don't think I control that. And definitely that ZygoteInit thing shouldn't be holding a context in a static way, but I don't control that either. Any tips on finding the causes better?
