你如何为 ionic/cordova 构建和部署到旧版本的 android [英] How do you build and deploy to an older version of android for ionic / cordova

问题描述

使用 Ionic 1.0.0 beta-8

创建新应用后，我构建并部署到 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，我收到了这个错误:

<代码>....- 构建后:[移动] 将 1 个文件移动到/home/admin/code/projects/myapp/ionic/platforms/android/ant-build[移动] 将 1 个文件移动到/home/admin/code/projects/myapp/ionic/platforms/android/CordovaLib/ant-build调试:建造成功总时间:6秒警告:未指定目标，正在部署到设备I8972b56ddac".使用apk:/home/admin/code/projects/myapp/ionic/platforms/android/ant-build/HelloCordova-debug-unaligned.apk在设备上安装应用程序.../home/admin/code/projects/myapp/ionic/platforms/android/cordova/node_modules/q/q.js:126扔e;^错误:无法在设备上启动应用程序:错误:无法将 apk 安装到设备:pkg:/data/local/tmp/HelloCordova-debug-unaligned.apk失败 [INSTALL_FAILED_OLDER_SDK]错误:/home/admin/code/projects/myapp/ionic/platforms/android/cordova/run:命令失败，退出代码为 8在 ChildProcess.whenDone (/usr/local/lib/node_modules/cordova/node_modules/cordova-lib/src/cordova/superspawn.js:131:23)在 ChildProcess.emit (events.js:98:17)在maybeClose (child_process.js:755:16)在 Process.ChildProcess._handle.onexit (child_process.js:822:5)错误:无法在 android 平台上运行应用程序.请参阅控制台了解更多信息.退出.

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

解决方案

这个问题和你的类似.堆栈溢出

去你的AndroidManifest.xml，找到这些来控制你的sdk buildversion.

//value 是 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.
在这里检查Android构建的API级别.

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

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

注意:我怀疑 android 2.2(API 级别 8)能否运行 API 级别 17(android 4.2).

Using Ionic 1.0.0 beta-8

After creating a new app, I built and deployed it to a Nexus 5 emulator and it worked fine. But when I tried to debug it on my Android 2.2 phone, I got this error:

....
-post-build:

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

debug:

How do I make the build work in ionic/cordova for android 4.x.x phones as well as android 2.2 phones?

解决方案

this question is similar to yours. stackoverflow

go to your AndroidManifest.xml, find these to control your sdk buildversion.

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

*targetSdk = tell phonegap which android build version to use,
*MinSdk is to limit user who want to download it.
check the API LEVEL of android build here.

In Your case: for android 2.2, use value= 8(API level 8)

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

NOTE: I doubt android 2.2(API level 8) can run API level 17(android 4.2).
