我正在尝试在我的手机android 2.3.6中测试一个项目，我收到错误消息：INSTALL_FAILED_OLDER_SDK
该应用程序是关于在两点之间绘制路线;
有我的代码： xml文件：

谢谢，因为钥匙我确定这是一个很好的
答案 0 :(得分：5)
或者：
您的设备未运行Android 2.3.6或
您的应用程序没有此清单，或
您误解了某些内容，或
您的设备或应用非常奇怪
INSTALL_FAILED_OLDER_SDK时才会出现 android:minSdkVersion。在您的情况下，android:minSdkVersion为7，即Android 2.1。因此，您不应该收到此错误。
答案 1 :(得分：2)
如果您使用的是Android工作室，则在清单文件旁边：
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="19" />
你也必须改变grandle.build文件
android {
compileSdkVersion 17
buildToolsVersion "17.0.0"
defaultConfig {
minSdkVersion 9
targetSdkVersion 16
}
}
答案 2 :(得分：0)
检查您是否已安装所需的最小值和/或与android sdk一起安装的目标版本SDK，在“工具”下查找匹配“Rev。”的构建工具;和匹配的API版本部分（即适用于SDK 19的Android 4.4.2 (API 19)。
答案 3 :(得分：-2)
片段在API级别11之前不可用，因此android 2.3.6无法运行它
