1、在Android studio中进行打开一个项目的文件之后,然后进行点击Android stuio中菜单中的“tools”
的选项。在弹出了下拉菜单中,进行选中下拉菜单中的“Generate JavaDoc”
的选项。
2、在弹出界面中 Output directory
是你即将生产的javadoc文件的存储位置,图中1指示的位置;正常点击ok即可;
但是如果有异常情况 比如空指针异常或者文档乱码
java.lang.NullPointerException 或者 java.nio.BufferOverflowException
等情况可在图中2的位置即 Other command line arguments
后面输入
-bootclasspath /Users/xiedingyuan/Documents/AndroidStudio/android-sdk-macosx/platforms/android-21/android.jar
jar指定你项目android.jar
的位置就行。在Other command line arguments
后输入(参数之间勿忘空格)
-encoding utf-8 -charset utf-8
即可解决乱码问题。
这样设置后在点击ok即可生产javadoc文档。
补充知识:android 原apk替换androidManifest.xml的metaData的多渠道自动打包
在已经编译出一个apk的情况下,其他的渠道只是改变androidManifest.xml的metaData信息,在这个情况下不需要再编译apk,只需要修改androidManifest.xml;
实现的思路如下:
1.获取源androidManifest.xml;因为apk里的androidManifest.xml是已经编译为二进制的文件,不好修改;可以使用apktool把源apk反编译得到androidManifest.xml的文本;
当然上面可以二进制的可以通过AXMLEditor.jar来修改,但这个修改metadata有点吃力,先简单开始直接使用apktool。
2.修改metaData:反编译得到androidManifest.xml的文本修改metaData信息;
3.得到二进制的androidManifest.xml:通过apktool再次编译为apk,解压androidManifest.xml出来即可;
3.替换原apk的二进制的androidManifest.xml,这样得到是全新的apk;
4.签名:删除apk的META-INF,使用jarsigner进行签名;
5.字节对齐:通过zipalign进行字节对齐;
利用android studio的product多渠道脚本、签名等信息可实现修改androidManifest.xml;脚本代码如下:
class ChannelBuildPlugin implements Plugin<Project> { String mSourceApkPath String mOutPutDir String mApkToolPath String mZip7ToolPath String mZipalignToolPath String mKeystore String mAlia String mStorepass String mSourceApkName String mProductName String mApplicationId void apply(Project project) { project.extensions.create("buildparam", ChannelBuildPluginExtension) project.task('autoBuildChannelProduct') << { println "autoBuildChannelProduct start " if (project.buildparam.sourceApkPath == null) { println "error !!!sourceApkPath == null" return } mSourceApkPath = project.buildparam.sourceApkPath File fp = new File(mSourceApkPath) if (!fp.exists()){ throw new FileNotFoundException(mSourceApkPath) } mSourceApkName = fp.getName() mOutPutDir = project.buildparam.outPutDir File outDir = new File(mOutPutDir) if (!outDir.exists()){ outDir.mkdirs() } mApkToolPath = project.buildparam.apkToolPath mZipalignToolPath = project.buildparam.zipalignToolPath mZip7ToolPath = project.buildparam.zip7ToolPath mKeystore = project.buildparam.keystore mAlia = project.buildparam.alia mStorepass = project.buildparam.storepass def signingConfigs project.copy { from "$mSourceApkPath" into "$mOutPutDir/workdir/sorceapk" } decodeApk() project.android.applicationVariants.all { variant -

} //重新签名 project.task('signApk') << { } } public void zipalign(Project project) { def apkFile = new File("$mOutPutDir/workdir/sorceapk/"+mProductName +"_app-release_aligned"+".apk") if (apkFile.exists()){ apkFile.delete() } apkFile = new File("$mOutPutDir/workdir/sorceapk/$mSourceApkName") if (apkFile.exists()) { def sdkDir Properties properties = new Properties() File localProps = project.rootProject.file("local.properties") if (localProps.exists()) { properties.load(localProps.newDataInputStream()) sdkDir = properties.getProperty("sdk.dir") } else { sdkDir = System.getenv("ANDROID_HOME") } if (sdkDir) { Properties prop = System.getProperties(); String os = prop.getProperty("os.name"); def cmdExt = os.contains("Windows") ?

下面是在主工程的脚本配置:
apply plugin:ChannelBuildPlugin buildparam{ sourceApkPath = "F:/svn/tv/app/app-release.apk" outPutDir = "F:/svn/tv/app" apkToolPath = "F:/svn/tv/app/apktool.bat" zip7ToolPath = "C:/Program Files/7-Zip/7z.exe" }
这样可以直接使用autoBuildChannelProduct这个任务即可编译所有的渠道的包。
说明:
1.AndroidManifest.xml的metaData的key与manifestPlaceholders的key要对应,可以大小写不同;
2.android studio配置了自动签名,不然需要手动配置签名信息。
使用的场景特别是需要热修复的情况,在多渠道的基准包中,必须要保持基准包的类及资源除AndroidManifest外都必须一样的环境,这样能保证所有渠道包均能热修复;
后续改进点:
1.不能修改applicationId、版本号等
2.不能使用默认配置的,每个渠道都必须配置完所有的metaData信息
