app crash when screen orientation changes???

[mr.xXx]

Somebody please help me..
recently i just develop android app using phonegap and jquery mobile..
After I changes the orientaion of the enumerator, the app crash.
I already search many place for solution, but still not solve the
problem.

[Gaurav dixit]

could you please elaborate your problem.if you don't want to change orientation then fix it in android manifest.

thanks

I had the same problem, setting minSdkVersion to 2 in
AndroidManifest.xml fixed it for me.

<uses-sdk android:minSdkVersion="2" />

[icache]

Setting minSdkVersion to 2 also worked for me - but that is not a
solution I can live with.

So I did some more testing. In my AndroidManifest.xml the
android:screenOrientation="landscape"
was in a second activity tag, below an activity tag that also included
an intent-filter section that
contained intent.action.MAIN & intent.category.LAUNCHER actions. I
moved the
android:screenOrientation="landscape" out of that second activity tag
to the first activity
tag (so it would be declared before the two action intents) That
worked! I then went back and
changed minSdkVersion back to 8 and it still worked! No crash, screen
maintains the
orientation I set.

Eclipse AndroidManifest>Application>Application Nodes>.~Activity &
com.phonegap.DroidGap both have
settings for orientation and both insert it into the second activity
tag after the
intent.action.MAIN & intent.category.LAUNCHER. Perhaps that is wrong -
at least from
my experience.

First, thank you mr.xXx for posting this issue and thank you everyone else for your replies. I stumbled upon this thread trying to solve the same problem.

Here's my solution

Add "screenSize" to the android:configChanges in each Activity tag (within the AnroidManifest.xml).

Like this:

android:configChanges="orientation|screenSize|keyboardHidden" 

And here's the reasoning

Looking through the Android docs, I found this page:

http://developer.android.com/guide/topics/resources/runtime-changes.html 

Towards the bottom of the page, there's a cautionary-note:

Caution: Beginning with Android 3.2 (API level 13), the "screen size" also changes when the device switches between portrait and landscape orientation. Thus, if you want to prevent runtime restarts due to orientation change when developing for API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), you must include the "screenSize" value in addition to the "orientation" value. That is, you must decalare android:configChanges="orientation|screenSize". However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device). 

That means that, if you are working with anything API level 13 or above, you need to add "screenSize" to PhoneGap's traditional recommendation of "orientation" and "keyboardHidden" in the android:configChanges.

So each activity tag should have

       android:configChanges="orientation|screenSize|keyboardHidden"

...like so:

<activity android:name="com.phonegap.DroidGap" android:label="@string/app_name" 

             android:configChanges="orientation|screenSize|keyboardHidden">

        <intent-filter>

        </intent-filter>

</activity>

Lowering the minSdkVersion below 13 works because Android no longer restarts the application based on a screenSize configuration change.

Run "adb logcat" so we can see what the root cause of the problem is.

I went back and re-read your manifest. It looks like the XML is not
valid. You have:

<activity
android:name=".HelloCordovaActivity"

android:label="@string/app_name" >
android:configChanges="orientation|screenSize|keyboardHidden"
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

when it should be:

<activity
android:name=".HelloCordovaActivity"
android:label="@string/app_name"
android:configChanges="orientation|screenSize|keyboardHidden" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

The config changes attribute has to be inside the activity tag.

[Adam]

That seems to fix it! Thanks!

[Simon MacDonald]

Make sure that your config changes are:

    android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale"

Your SDK line should be something like:

    <uses-sdk android:minSdkVersion="9" android:targetSdkVersion="17"/>

If Eclipse is still giving you a red x on the line for config changes, right click on the project and close it. Then double click it to open and it should go away.

I am having exactly the same issue as Alberto. I have a minSdkVersion=10 targetSdkVerison=17. I've added PhoneGap's recommendation configChanges="orientation|screen|keyboardHidden"

When I try to add "screenSize" I get an error message saying it is not a valid value. 
I'm developing on Eclipse Juno Java EE for Web Developers.

My app restarts when the orientation changes.

I'm running the app on a Nexus 7 Android 4.2.2 and a Droid X Android 2.3.4. They both show the same behavior.

Can anyone shed some light on what is going on?

I've got a similar issue and googling for days lead me to nowhere.
I've added the lines said in this thread but the application still restar as soon as screen rotate.
First issue i've found is that screenSize is not allowed, looking at possible tags i've found screeLayout... but it doesn't work either.


I've got a page with authentication (index.html) that uses jQuery changePage to show main Application page on authentication success..

        //console.log('Content'+content);
        window.plugins.Base64ToString.convert(content, {},
                function(result) {
                    decodedContent = result;
                    console.log('Decoded' + decodedContent);
                    if (decodedContent.length > 0) {
                        var x = $(decodedContent);
                        myUserSID = x.attr('user_sid');
                        console.log('UserSID' + myUserSID);
                        var store = window.sessionStorage.setItem("UserSID", myUserSID);
                        $.mobile.changePage('mainPage.html');
                    } else {
                        // TODO not logged alert.

                    }
                    ;
                }, function(error) {
            alert(error);
        });
},

on main page a screen rotation lead to go back to authentication page.

Same typo here.  Thanks!

You'd think after using XML extensively for 12+ years, I would have avoided such a simple typo.  Oops!

BTW, it's worth noting that not only is it UNECESSARY to add screenSize when using API level less than 13, but also it is INCORRECT to add it in that case.  Before API level 13, the screenSize value was not valid as part of android:configChanges, and causes this error at compile time:

     String types not allowed (at 'configChanges' with value  'orientation|keyboardHidden|keyboard|screenSize|locale').

Simon,

Thanks for your help. It was the trigger that helped me to finally track down the cause of the problem. The invalid "screenSize" was the important clue. I've encountered this kind of error before. My project was targeted at Android 2.3.3. Here's how I was finally able to fix this:

1. Set the "android:minSdkVersion" property in your AndroidManifest.xml to the oldest version of Android you are targeting your application at (for me it was 10, i.e. Android v2.3.3).
2. In the Eclipse "Package Explorer", right-click on the project.
3. In the pop-up context menu, select "Properties". The properties dialog opens.
4. Select "Android" in the left side panel. The right side of the dialog will display "Project Build Target"
5. Pick a version of "Android" or "Google API" that is greater than 13 or 14. (I'm not sure which one has the fix). I used 17.
6. Click the "Apply" button.
7. Click the "Ok" button.
8. Very Important : Clean the project. Go to the Eclipse main menu: Project > Clean...
9. Make sure that your PhoneGap project is selected.
1.  use either "Clean all projects" or "Clean projects selected below"
2. Click the "Ok" button.
10. Build and deploy your app on your oldest targeted device.

That solved my problem.

Thank's a lot. My App runing in the perfect.
