android - 如何为 ionic/cordova 构建和部署到旧版本的 android

Question

使用 Ionic 1.0.0 beta-8

创建新应用后，我构建并将其部署到 Nexus 5 模拟器，它运行良好。但是当我尝试在我的 Android 2.2 手机上调试它时，我得到了这个错误:

....
-post-build:
     [move] Moving 1 file to /home/admin/code/projects/myapp/ionic/platforms/android/ant-build
     [move] Moving 1 file to /home/admin/code/projects/myapp/ionic/platforms/android/CordovaLib/ant-build

debug:

如何使构建在 ionic/cordova 中适用于 android 4.x.x 手机和 android 2.2 手机？

这个问题和你的类似。 stackoverflow

转到您的 AndroidManifest.xml，找到这些来控制您的 sdk 构建版本。

<preference name="android-minSdkVersion" value="XX"> // value is the API LEVEL
<preference name="android-targetSdkVersion" value="XX">

*targetSdk = 告诉 phonegap 使用哪个 android build 版本，
*MinSdk 是限制想要下载它的用户。
检查android build的API LEVEL here .

在您的情况下: 对于 android 2.2，使用 value= 8(API 级别 8)

    <preference name="android-minSdkVersion" value="8"> //android 2.2
    <preference name="android-targetSdkVersion" value="17"> //android 4.2

注意:我怀疑 android 2.2(API 级别 8)可以运行 API 级别 17(android 4.2)。
