App works slow after initializing the map on Android

[starostin]

Hello. I have some problem in Android. After initializing map my application starts work very slow. All css animations and transactions. On version 1.1.2 everything was ok, but on 1.2.2 it is happened. Is there any solution? I have tried to remove the map each time, when I detach the view, but it does not help( Can you suggest anything, please

Some people reports similar this case, but I can not reproduce the same issue. I think the webview(browser view) of Android is related with this issue. What Android device and Android version do you use? Could you show me the screen capture of "system settings > About phone"?

[starostin]

Nexus 7 2, android 4.4.4. Weird that on old version everything worked well

[starostin]

And on Nexus 7 some transitions even does not work at all (

[wf9a5m75]

Um, that's weird. I usually tested on Nexus 7 (2012), but there is no issue. Do you use any other plugin with this plugin?

[wf9a5m75]

And do you use the ionic framework or something?

[starostin]

I use a lot plugins, we develop a big app. No, I don't use ionic. We use backbone

[wf9a5m75]

Could you tell me what plugins do you use?

[starostin]

Is the reason could be in other phonegap plugins?

[wf9a5m75]

Thank you. I will check those plugins tonight.

[starostin]

Thank you very much)

[wf9a5m75]

Oh, could you help me one more thing? Because of you are using Android 4.4.4, you can record the screen capture as video, and I haven't reproduced this issue yet. In order to confirm the issue, could you take a video then upload to the youtube?

[starostin]

I can try

[wf9a5m75]

Thank you for your help.

I added some code to improve the webview performance generally. Try the plugin on the test branch.

$> cordova plugin add https://github.com/wf9a5m75/phonegap-googlemaps-plugin#test --variable ...

[starostin]

I have replaced GoogleMaps.java, but it is still slow(

[wf9a5m75]

I see.

[wf9a5m75]

How about comment out the below lines? https://github.com/wf9a5m75/phonegap-googlemaps-plugin/blob/master/www/googlemaps-cdv-plugin.js#L1969-L2003

[starostin]

I have already at home, so I will check it tomorrow. Thanks

[starostin]

No, it is still slow

[starostin]

Seems I have found the problem. There two lines with webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null); if comment them, everything works ok)

[wf9a5m75]

I added them today. On Oct 20, 2014 11:43 PM, "starostin" notifications@github.com wrote:

[starostin]

But after commenting this lines screen with map blinks after first opening

[starostin]

they are on GoogleMaps.java line 175, and MyPluginLayout.java line 56

[starostin]

Is there any solutions to avoid blinks?)

[michaeleparkour]

Really can confirm that overriding to Software mode slows app. But if just comment these lines - map blinks on creating and even with wrong sizes, and refreshLayout() doesn't helps.

[wf9a5m75]

webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

The above line needs to place the map under the browser view. Because some Android webview does not change the opacity without this specify.

[starostin]

It is sad. But for me better blinks than slow app(

[wf9a5m75]

Ok, how about the remove android:hardwareAccelerated="true" from the AndroidManifest.xml file?

[starostin]

I will try, but I thought without this my app become slower, or no?

[wf9a5m75]

I don't know. I haven't reproduced the slower situation even if I use Nexus 7 2012 model with Android 4.4.4 (old one than yours).

[starostin]

It did not help( Thank you for attention)

[wf9a5m75]

@starostin

Add android:largeHeap="true" attribute into <application> tag in the ApplicationManifest.xml file under the platforms/android/

The plugin can not add this attribute automatically, so please add by hand.

android:largeHeap="true" allows large heap memory allocation.

I don't know this helps to solve your case, but the issue #224, which is similar case with yours, is effected at least for me.

If this does not help, please share your project with me using github. I will investigate yours.

[wf9a5m75]

@starostin Any update?

[starostin]

Sorry, was not at work. I set android:largeHeap="true", but it did not help. A cant share project, because it is not my project( I will create new one, and then give you an access

[wf9a5m75]

@starostin Thank you, I'll be waiting.

[wf9a5m75]

Since there is no new information, I close this issue at once. However you can still discuss for this. If you have a new information, please let me know through this thread.
