除了具有最新 API(29) 的设备外，min-Sdk 不工作
min-Sdk does not work besides the device with the latest API(29)
我用 compileSdkVersion 29 和 buildToolsVersion "29.0.0" 构建了一个项目。当我设置 minSdkVersion 21 并尝试 运行 使用 Nexus S（API 21）和 Nexus 5X（API 26）的项目时。它根本不起作用。只有当我 运行 最新的 API(29) 的项目时，它才有效。你能教我如何正确使用 minSdkVersion 吗？

OutOfMemoryError 是 android 中最常见的问题，尤其是在处理位图时。当由于内存不足 space 而无法分配对象时，Java 虚拟机 (JVM) 会抛出此错误，而且垃圾收集器无法释放一些 space.
您可以在清单文件中添加以下实体 android:hardwareAccelerated="false"，android:largeHeap="true" 它适用于某些环境。
<application
android:allowBackup="true"
android:hardwareAccelerated="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="@style/AppTheme">
