android 10 frameworks 中调用第三方jar

1.客制需求，但是没有直接烧写imei的工具，客制应用又需要读取imei的值
（内置客户授权信息，更改imei读取方法,采用内置.xlsx文件的方式）

2.使用的poi 解析方式（aa-poi-3.10-min-0.1.5.jar，aa-poi-ooxml-schemas-3.10-reduced-more-0.1.5.jar）

3.需要把jar导入到framework供系统调用

@SuppressAutoDoc // No support for device / profile owner or carrier privileges (b/72967236).
    @RequiresPermission(android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE)
    public String getImei(int slotIndex) {
        ITelephony telephony = getITelephony();
        if (telephony == null) return null;
        return xxx.getCustomKey("key","path");
        /*try {
            return telephony.getImeiForSlot(slotIndex, getOpPackageName());
        } catch (RemoteException ex) {
            return null;
        } catch (NullPointerException ex) {
            return null;
        }*/
    }

4.参考系统内置 kxml2-2.3.0.jar(\android\prebuilts\misc\common\kxml2\kxml2-2.3.0.jar) 方式导入上述jar文件，
在同级目录下新建poi和ooxml文件夹，导入jar和配置Android.bp文件
poi\Android.bp

Index: poi\Android.bp
java_import_host {
    name: "poi",
    jars: ["aa-poi-3.10-min-0.1.5.jar"],
    installable: true,
}
java_import {
    name: "poi-android",
    jars: ["aa-poi-3.10-min-0.1.5.jar"],
}
Index: ooxml\Android.bp
java_import_host {
    name: "ooxml",
    jars: ["aa-poi-ooxml-schemas-3.10-reduced-more-0.1.5.jar"],
    installable: true,
}
java_import {
    name: "ooxml-android",
    jars: ["aa-poi-ooxml-schemas-3.10-reduced-more-0.1.5.jar"],
}

jar配置完成再out\soong.intermediates\prebuilts\misc\common\下面可以看到对应的文件库

5.然后在对应的位置frameworks/base/Android.bp添加引用

Index: frameworks/base/Android.bp
 static_libs: [
       ...
        "fo_ota_lib",
        "ooxml-android",

6.更新api (make update-api)

******************************
You have tried to change the API from what has been previously approved.
To make these errors go away, you have two choices:
   1) You can add "@hide" javadoc comments to the methods, etc. listed in the
      errors above.
   2) You can update current.txt by executing the following command:
         make update-api
      To submit the revised current.txt to the main Android repository,
      you will need approval.

7.处理错误

1)问题1. 删除jar包中对应的class类
Check failed: superclass != nullptr Superclass Ljava/awt/Graphics2D; of class Lorg/apache/poi/hssf/usermodel/DummyGraphics2d; 
from dex file "out/soong/.intermediates/frameworks/base/framework/android_common/aligned/framework.jar!classes3.dex" 
was not found. Either the superclass is missing or it appears later in the classpath spec.
...

2)问题2
