如何在android gradle插件环境中支持osgi? [英] How to support osgi in android gradle plugin environment?
问题描述
我想使用apk作为osgi包,然后将其加载到宿主应用程序中。
现在,它工作正常。但是我必须在将osgi包推送到手机之前手动执行以下操作:
$ b
- 使用WinRAR打开osgi bundle apk文件。
- 将构建的类(在extension-a\build\intermediates\classes\debug\com中)拖到包文件的根目录中。
- 拖动修改MANIFEST.MF(包括OSGI配置信息)到包文件的META-INFO / MANIFEST.MF。
- 最后签署包apk。
我想知道如何编写一些gradle脚本来自动执行这些操作?
我使用gradle 2.2。 1和'com.android.tools.build:gradle:1.2.3'。
ps:
我知道有一个gradle插件osgi可以为osgi bunlde生成MANIFEST.MF,但只适用于javagradle插件。
我不能在androidgradle插件中使用它。
我试过这种方法:
android.applicationVariants.all {variant - >
variant.outputs [0] .packageApplication.doLast {
String zipFileName = variant.outputs [0] .outputFile.name
String inputFile ='MANIFEST.MF'
def zipIn = variant.outputs [0] .outputFile
def zip = new ZipFile(zipIn.getAbsolutePath())
def zipTemp = new File(zipFileName +_temp)
zipTemp .deleteOnExit()
def zos = new ZipOutputStream(new FileOutputStream(zipTemp))
def toModify ='META-INFO / MANIFEST.MF'
(e in zip。条目()){
if(!e.name.equalsIgnoreCase(toModify)){
zos.putNextEntry(e)
zos<< zip.getInputStream(e).bytes
} else {
zos.putNextEntry(new ZipEntry(toModify))
zos<<新文件(inputFile).bytes
}
zos.closeEntry()
}
zos.close()
zipIn.delete()
zipTemp.renameTo(zipIn)
}
}
但没有成功:
- 如果使用gradle clean build,它会报告out-file.apk找不到。
-
如果out-file.apk存在,它会报告异常:
java.util.zip.ZipException:invalid entry compressed size(expected 400但得到了401字节)
在java.util.zip.ZipOutputStream.closeEntry(未知源代码)
任何帮助将不胜感激!
我找到了解决方法。

I want to use apk as an osgi bundle, and then load it in a host application.
Now, it works ok. But I must manually do these things before push the osgi bundle to phone:
- Open osgi bundle apk file with WinRAR.
- Drag the built classes(in extension-a\build\intermediates\classes\debug\com) to the bundle file's root directory.
- Drag the modified MANIFEST.MF (including OSGI config info) to the bundle file's META-INFO/MANIFEST.MF .
- Sign the bundle apk at last.
I want to know how to write some gradle scripts to do these things automatically?
I use gradle 2.2.1, and 'com.android.tools.build:gradle:1.2.3'.
ps: I know there is a gradle plugin "osgi" can generate the MANIFEST.MF for osgi bunlde, but it only works with "java" gradle plugin. I can't use it with "android" gradle plugin.
I tried this way :
android.applicationVariants.all { variant ->
variant.outputs[0].packageApplication.doLast {
String zipFileName = variant.outputs[0].outputFile.name
String inputFile = 'MANIFEST.MF'
def zipIn = variant.outputs[0].outputFile
def zip = new ZipFile(zipIn.getAbsolutePath())
def zipTemp = new File(zipFileName + "_temp")
zipTemp.deleteOnExit()
def zos = new ZipOutputStream(new FileOutputStream(zipTemp))
def toModify = 'META-INFO/MANIFEST.MF'
for(e in zip.entries()) {
if(!e.name.equalsIgnoreCase(toModify)) {
zos.putNextEntry(e)
zos << zip.getInputStream(e).bytes
} else {
zos.putNextEntry(new ZipEntry(toModify))
zos << new File(inputFile).bytes
}
zos.closeEntry()
}
zos.close()
zipIn.delete()
zipTemp.renameTo(zipIn)
}
}
But without success:
- If use "gradle clean build", it report "out-file.apk" not found.
If the out-file.apk exists, it report exception:
java.util.zip.ZipException: invalid entry compressed size (expected 400 but got 401 bytes) at java.util.zip.ZipOutputStream.closeEntry(Unknown Source)
Any help would be appreciated!
I find a way to solve it.
