我要评论引入 aar
在模块源码根文件下新建文件夹 libs，复制要引入的 arr文件至此，新建 Android.bp
新增如下语句,这里以 lottie.arr 为例
android_library_import {
name: "lib-lottie",
aars: ["lottie-2.8.0.aar"],
sdk_version: "current",
}
然后在模块目录下 Android.bp 文件中的 android_app {} 中 static_libs 引入 “lib-lottie”,
android_app {
name: "LiveTv",
srcs: ["src/**/*.java"],
static_libs: [
"lib-lottie",
"android-support-annotations",
"android-support-compat",
"android-support-core-ui",
"androidx.tvprovider_tvprovider",
"android-support-v4",
....
这样编译就ok了，如果编译报错，
Error: Compilation can’t be completed because some library classes are missing.
Compilation failed
可以尝试将 “lib-lottie”, 移动到 libs: [] 中再次尝试
如果aar中带资源文件，需要将aar解压拷贝资源文件，不然编译时会提示找不到资源，运行时会报错
解压 lottie-2.8.0.aar，在模块源码根文件夹下新建 res-lottie 文件夹，将资源文件拷贝到此目录
模块目录下 Android.bp 文件中的 resource_dirs: [] 引入
android_app {
name: "LiveTv",
srcs: ["src/**/*.java"],
resource_dirs: [
"res",
"res_ext",
"res-lottie",
],
static_libs: [
"lib-lottie",
"android-support-annotations",
"android-support-compat",
"android-support-core-ui",
"androidx.tvprovider_tvprovider",
"android-support-v4",
....
],
aaptflags: [
"--extra-packages",
"com.airbnb.lottie",
],
同时增加 aar 对应的包名 aaptflags，以便生成对应包名 R 文件
aaptflags --extra-packages com.airbnb.lottie, 编译时会生成 com.airbnb.lottie.R
多个aar增按照如上操作配置多个即可
引入 jar
在模块源码根文件下新建文件夹 libs，复制要引入的 jar 包至此，新建 Android.bp
新增如下语句,这里以 opencv.jar 为例
java_import {
name: "face-opencv-jar",
jars: ["opencv.jar"],
sdk_version: "current",
}
然后在模块目录下 Android.bp 文件中的 android_app {} 中 libs 引入 “face-opencv-jar”,
android_app {
name: "LiveTv",
libs: [
"telephony-common",
"mediatek-framework",
"ims-common",
"face-opencv-jar",
],
这样编译就ok了, jar包相对简单一些
引入 so
在模块源码根文件下新建文件夹 armeabi，复制要引入的 so 至此，在libs中新建 Android.bp
新增如下语句,这里以 libjniopencv_face.so 为例, arm 和 arm64 分别对应32/64的so库,针对源码环境
位数都是确定的，所以我们就写成一样了
cc_prebuilt_library_shared {
name: "libjniopencv_face",
arch: {
arm: {
srcs: ["armeabi/libjniopencv_face.so"],
},
arm64: {
srcs: ["armeabi/libjniopencv_face.so"],
},
},
}
然后在模块目录下 Android.bp 文件中的 android_app {} 中 jni_libs 引入 “libjniopencv_face”,
android_app {
name: "LiveTv",
jni_libs: [
"libjniopencv_face",
]
]
一个完整的包含 aar/jar/so Android.bp

----Android.bp
----lottie-2.8.0.aar
----face-opencv-jar
----armeabi
-----libjniopencv_face.so
-----libopencv_text.so

name: "lib-lottie",
aars: ["lottie-2.8.0.aar"],

}
java_import {

jars: ["opencv.jar"],
sdk_version: "current",
}
cc_prebuilt_library_shared {
name: "libjniopencv_face",
arch: {
arm: {
srcs: ["armeabi/libjniopencv_face.so"],
},
arm64: {
srcs: ["armeabi/libjniopencv_face.so"],
},
},
}
cc_prebuilt_library_shared {
name: "libopencv_text",
arch: {
arm: {
srcs: ["armeabi/libopencv_text.so"],
},
arm64: {
srcs: ["armeabi/libopencv_text.so"],
},
},
}

小技巧
一般需要引入的so库都会是几十个，每一个都需要在Android.bp配置对应的 cc_prebuilt_library_shared
挨个复制会很浪费时间，自信观察格式都是固定的，我们可以通过遍历文件夹来生成这个json串
将所有 so 库文件拷贝至 sdcard/Android/armeabi/,遍历读取文件名，按默认格式写入txt文件即可
private void getSoJson() {
String fileAbsolutePath = Environment.getExternalStorageDirectory().getPath() + "/Android/armeabi/";
Log.e("eee", "fileAbsolutePath ： " + fileAbsolutePath);
File file = new File(fileAbsolutePath);
File[] subFile = file.listFiles();
String json = "";
String soName = "";
for (int iFileLength = 0; iFileLength < subFile.length; iFileLength++) {
if (!subFile[iFileLength].isDirectory()) {
String filename = subFile[iFileLength].getName();
String name = filename.split("\\.")[0];
Log.e("eee", "filename ： " + filename + " name=" + name);
json += "cc_prebuilt_library_shared {\n" +
" name: \"" + name + "\",\n" +
" arch: {\n" +
" arm: {\n" +
" srcs: [\"armeabi/" + filename + "\"],\n" +
" },\n" +
" arm64: {\n" +
" srcs: [\"armeabi/" + filename + "\"],\n" +
" },\n" +
" },\n" +
"}" + "\r\n";
soName += "\""+name+"\"," + "\r\n";
}
}
Log.e("eee", "soJson =" + json);
write2File("so.txt", json);
write2File("libs.txt", soName);
}
private void write2File(String fileName, String data) {
String strFilePath = Environment.getExternalStorageDirectory().getPath() + "/Android/" + fileName;
String strContent = data + "\r\n";
try {
File sfile = new File(strFilePath);
if (!sfile.exists()) {
Log.d("TestFile", "Create the file:" + strFilePath);
sfile.getParentFile().mkdirs();
sfile.createNewFile();
}
RandomAccessFile raf = new RandomAccessFile(sfile, "rwd");
raf.seek(sfile.length());
raf.write(strContent.getBytes());
raf.close();
} catch (Exception e) {
Log.e("TestFile", "Error on write File:" + e);
}
}
