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
libs
----Android.bp ----lottie-2.8.0.aar ----face-opencv-jar ----armeabi -----libjniopencv_face.so -----libopencv_text.so
libs/Android.bp
android_library_import { name: "lib-lottie", aars: ["lottie-2.8.0.aar"], sdk_version: "current", } java_import { name: "face-opencv-jar", 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"], }, }, }
模块根路径Android.bp
android_app { name: "LiveTv", srcs: ["src/**/*.java"], // TODO(b/122608868) turn proguard back on optimize: { enabled: false, }, // It is required for com.android.providers.tv.permission.ALL_EPG_DATA privileged: true, sdk_version: "system_current", min_sdk_version: "23", // M resource_dirs: [ "res", "material_res", "res-lottie", ], libs: [ "face-opencv-jar", ], static_libs: [ "android-support-compat", "android-support-core-ui", "androidx.tvprovider_tvprovider", "android-support-v4", "android-support-v7-appcompat", "android-support-v7-palette", "android-support-v7-preference", "android-support-v7-recyclerview", "android-support-v14-preference", "android-support-v17-leanback", "android-support-v17-preference-leanback", "lib-lottie", ], jni_libs: [ "libjniopencv_face", "libopencv_text", ] javacflags: [ "-Xlint:deprecation", "-Xlint:unchecked", ], aaptflags: [ "--version-name", version_name, "--version-code", version_code, "--extra-packages", "com.android.tv.tuner", "--extra-packages", "com.airbnb.lottie", ], }
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); } }
