Question

阅读stackoverflow站点中的几篇帖子后我尝试使用Frame动画

来构建动画

private void startAnimation(){
    fireAnimation = new AnimationDrawable();
    fireAnimation.addFrame(getResources().getDrawable(R.drawable.fire1), 100);
    fireAnimation.addFrame(getResources().getDrawable(R.drawable.fire2), 100);
    fireAnimation.addFrame(getResources().getDrawable(R.drawable.fire3), 100);
    fireAnimation.addFrame(getResources().getDrawable(R.drawable.fire4), 100);
    ...
   fireAnimation.addFrame(getResources().getDrawable(R.drawable.fire16), 100);

}

然后在onCreate（）中我做startActivity（）;

But I have an error

我有16张图片，当我只放4张图片时。我能做些什么来减轻图像的重量？我应该减小尺寸（600 * 650）m，哪些足以保证质量好？

Answer 1

您可以缩小图像尺寸要么您可以尝试增加VM堆。

尝试在adb shell中设置以下内容。

setprop dalvik.vm.heapsize“12m”

Android：FrameAnimation和Bitmap大小超过
