我的应用程序可能在其主线程上做过多的工作

Question

I'm a new Android Studio programmer and I have this error that make my app crash sometimes. I put 6 ImageView into a layout with 12 buttons and my app say "I/Choreographer: Skipped 699 frames! The application may be doing too much work on its main thread." when I start the layout. How can I solve this? Heres the code

This is what I want to do: Emulator Preview

App run but is slow and It may crash.

Answer 1

Maybe your images size are too big. Check their resolution and resize them if there are too big. Do not use more than 800*800 images and try to have diffrent images for diffrent devices by putting suitable image at the right drawable folder.

Answer 2

Try :

<application
    android:largeHeap="true"
    tools:replace="android:theme,android:icon" >

And Put drawable in every drawable folder. Don't only put drawable in drawable-xhdpi or other.Put drawable in drawable-xhdpi drawable-xxhdpi drawable-hdpi .

Because if you have no drawable fit your phone. drawable will be scale and cast memory.
