我在使用 Galaxy S 系列时遇到了一些问题，展示视图在任何其他设备上都能完美运行，但在 Galaxy S 设备上出现以下错误。

java.lang.OutOfMemoryError: Failed to allocate a 5760012 byte allocation with 3573238 free bytes and 3MB until OOM at dalvik.system.VMRuntime.newNonMovableArray(VMRuntime.java) at android.graphics.BitmapFactory.nativeDecodeAsset(BitmapFactory.java)

这是产生上述错误的代码：

private void showcase() {
        if (SaveSharedPreference.isMainActivity(this)) {
            switch (counter) {
                case 0:
                    new ShowcaseView.Builder(this)
                            .withMaterialShowcase()
                            .setContentTitle("Esta é a tela inicial:")
                            .setStyle(R.style.CustomShowcaseThemeNext)
                            .setShowcaseEventListener(new SimpleShowcaseEventListener() {
                                @Override
                                public void onShowcaseViewDidHide(ShowcaseView showcaseView) {
                                    counter++;
                                    showcase();
                                }
                            })
                            .build();
                    break;

                case 1:
                    new ShowcaseView.Builder(this)
                            .setContentTitle("Selecione o tipo de combustível:")
                            .setTarget(new ViewTarget(R.id.spinner, this))
                            .setShowcaseDrawer(new CustomShowcaseView(this, findViewById(R.id.spinner).getWidth(), findViewById(R.id.spinner).getHeight()))
                            .setShowcaseEventListener(new SimpleShowcaseEventListener() {
                                @Override
                                public void onShowcaseViewDidHide(ShowcaseView showcaseView) {
                                    counter++;
                                    showcase();
                                }
                            })
                            .build();
                    break;

                case 2:
                    new ShowcaseView.Builder(this)
                            .withMaterialShowcase()
                            .setTarget(new ViewTarget(R.id.fab2, this))
                            .setContentTitle("Clique neste botão para procurar combustível ao redor:")
                            .setStyle(R.style.CustomShowcaseThemeNext)
                            .setShowcaseEventListener(new SimpleShowcaseEventListener() {
                                @Override
                                public void onShowcaseViewDidHide(ShowcaseView showcaseView) {
                                    counter++;
                                    showcase();
                                }
                            })
                            .build();
                    break;

                case 3:
                    new ShowcaseView.Builder(this)
                            .withMaterialShowcase()
                            .setTarget(new ViewTarget(R.id.fab2, this))
                            .setContentTitle("Lembre-se:")
                            .setContentText("É necessário estar com o GPS ligado")
                            .setStyle(R.style.CustomShowcaseTheme2)
                            .setShowcaseEventListener(new SimpleShowcaseEventListener() {
                                @Override
                                public void onShowcaseViewDidHide(ShowcaseView showcaseView) {
                                    counter++;
                                    showcase();
                                }
                            })
                            .build();
                    SaveSharedPreference.mainActivityFirst(this);
                    break;
            }
        }
    }

我无法弄清楚错误来自哪里，所以寻求任何建议。

OutOfMemoryError是 android 中最常见的问题，尤其是在处理位图时。当由于内存空间不足而无法分配对象并且垃圾收集器无法释放一些空间时，Java 虚拟机 (JVM) 会引发此错误。

磁盘上文件的大小不一定与内存中文件的大小一致。文件很可能是压缩的，而解码时则不会。您需要在计算中考虑到这一点。

您可以参考这篇文章了解如何高效加载位图？
如何有效地加载大型位图？

android:largeHeap="true"虽然在这里使用谷歌的摘录来解释它 不是一个好主意，

但是，请求大堆的能力仅适用于一小部分可以证明需要消耗更多 RAM 的应用程序（例如大型照片编辑应用程序）。永远不要仅仅因为你的内存已经用完并且需要快速修复就请求一个大堆——只有在你知道所有内存被分配到哪里以及为什么必须保留它时才应该使用它。然而，即使您确信您的应用程序可以证明大堆是合理的，您也应该尽可能避免请求它。使用额外的内存将越来越多地损害整体用户体验，因为垃圾收集将花费更长的时间，并且在任务切换或执行其他常见操作时系统性能可能会变慢。

这是文档的完整链接 https://developer.android.com/training/articles/memory.html

但是，您可以尝试在 Android 清单文件中设置它并运行。

问题已解决，从 ShowcaseView.java 更改方法隐藏从此：

@Override
    public void hide() {
        // If the type is set to one-shot, store that it has shot
        shotStateStore.storeShot();
        mEventListener.onShowcaseViewHide(this);
        fadeOutShowcase();
    }

对此：

@Override
    public void hide() {
        // If the type is set to one-shot, store that it has shot
        clearBitmap();
        shotStateStore.storeShot();
        mEventListener.onShowcaseViewHide(this);
        fadeOutShowcase();
    }
