如何使用“ libsu”库（或adb）在Android Q上安装拆分的APK文件？ [英] How to use "libsu" library (or adb) to install split APK files on Android Q?
问题描述
使用root，我知道对于单个APK文件，我们可以使用 libsu库（ 此处 ）进行安装：
Using root, I know that for a single APK file, we can use the "libsu" library (here) to install as such:
val installResult = Shell.su("pm install -t \"$filePath\"").exec()
如果失败（在新的Android版本上失败，则不确定从哪个版本失败），例如（写此 此处 ）：
And if that failed (fails on new Android versions, not sure from which), as such (written about this here):
val installResult = Shell.su("cat \"$filePath\" | pm install -t -S ${apkSource.fileSize}").exec()
我也知道，在安装拆分的APK文件时，事情变得非常混乱（如 此处 ）。首先，您需要使用 pm install-create命令创建一个会话：
I also know that things got quite messy when it comes to installing split APK files (as shown here). First you need to create a session, using the "pm install-create" command:
var sessionId: Int? = null
run {
val sessionIdResult =
Shell.su("pm install-create -r -t").exec().out
val sessionIdPattern = Pattern.compile("(\\d+)")
val sessionIdMatcher = sessionIdPattern.matcher(sessionIdResult[0])
sessionIdMatcher.find()
sessionId = Integer.parseInt(sessionIdMatcher.group(1)!!)
Log.d("AppLog", "sessionId:$sessionId")
}
然后，您必须推送每个APK文件，例如：
Then you have to "push" each of the APK files, as such:
for (apkSource in fileInfoList) {
val filePath = File(apkSource.parentFilePath, apkSource.fileName).absolutePath
Log.d("AppLog", "installing APK : $filePath ${apkSource.fileSize} ")
val result = Shell.su("pm install-write -S ${apkSource.fileSize} $sessionId \"${apkSource.fileName}\" \"$filePath\"").exec()
Log.d("AppLog", "success pushing apk:${apkSource.fileName} ? ${result.isSuccess}")
}
然后您使用 pm install-commit 提交更改：
val installResult = Shell.su("pm install-commit $sessionId").exec()
关于它的文档全部：
install-create [-lrtsfdg] [-i PACKAGE] [--user USER_ID|all|current]
[-p INHERIT_PACKAGE] [--install-location 0/1/2]
[--install-reason 0/1/2/3/4] [--originating-uri URI]
[--referrer URI] [--abi ABI_NAME] [--force-sdk]
[--preload] [--instantapp] [--full] [--dont-kill]
[--force-uuid internal|UUID] [--pkg PACKAGE] [--apex] [-S BYTES]
[--multi-package] [--staged]
Like "install", but starts an install session. Use "install-write"
to push data into the session, and "install-commit" to finish.
install-write [-S BYTES] SESSION_ID SPLIT_NAME [PATH|-]
Write an apk into the given install session. If the path is '-', data
will be read from stdin. Options are:
-S: size in bytes of package, required for stdin
install-commit SESSION_ID
Commit the given active install session, installing the app.
问题
一切正常直到Android P，但由于某种原因，它在Q beta 6上失败，向我显示此错误：
The problem
This all worked fine till Android P, but for some reason, it failed on Q beta 6, showing me this error:
avc: denied { read } for scontext=u:r:system_server:s0 tcontext=u:object_r:sdcardfs:s0 tclass=file permissive=0
System server has no access to read file context u:object_r:sdcardfs:s0 (from path /storage/emulated/0/Download/split/base.apk, context u:r:system_server:s0)
Error: Unable to open file: /storage/emulated/0/Download/split/base.apk
Consider using a file under /data/local/tmp/
我尝试过的文件
这类似于我为单个APK找到的情况， 此处 ，所以我认为也许也可以在此处应用类似的解决方案：
What I've tried
This is similar to the case I've found for the single APK , here, so I thought that maybe a similar solution can be applied here too:
val result = Shell.su("cat $filePath | pm install-write -S ${apkSource.fileSize} $sessionId \"${apkSource.fileName}\" \"$filePath\"").exec()
这仍然仅适用于Android P及更低版本。
This still worked only on Android P and below.
因此，看到我看过的原始代码起作用了，它使用了InputStream，将其作为文档暗示，是可能的。这就是他们拥有的东西：
So seeing that the original code I looked at worked, it uses an InputStream, which as the docs imply, is possible. Here's what they had:
while (apkSource.nextApk())
ensureCommandSucceeded(Root.exec(String.format("pm install-write -S %d %d \"%s\"", apkSource.getApkLength(), sessionId, apkSource.getApkName()), apkSource.openApkInputStream()));
所以我尝试的是这样：
val result = Shell.su("pm install-write -S ${apkSource.fileSize} $sessionId \"${apkSource.fileName}\" -")
.add(SuFileInputStream(filePath)).exec()
不幸的是，这也行不通。
Sadly this also didn't work.
我知道我可以复制相同的代码，但是还有办法改用库（因为它会更短且更优雅）？如果是这样，我该怎么办？
I know I could just copy the same code, but is there still a way to use the library instead (because it will be shorter and more elegant)? If so, how could I do it?
推荐答案
好，我不知道如何使用该库来安装split- apk，但这是一个短代码，似乎可以在其他库中使用：
OK I don't know how to use this library to install the split-apk, but here's a short code that seems to work using a different library :
build.gradle
//https://github.com/topjohnwu/libsu
implementation "com.github.topjohnwu.libsu:core:2.5.1"
单个/拆分apk文件的基类：
Base class of a single/split apk file :
open class FileInfo(val name: String, val fileSize: Long, val file: File? = null) {
open fun getInputStream(): InputStream = if (file!= null) FileInputStream(file) else throw NotImplementedError("need some way to create InputStream")
}
获取根目录并安装：
Shell.getShell {
val isRoot = it.isRoot
Log.d("AppLog", "isRoot ?$isRoot ")
AsyncTask.execute {
val apkFilesPath = "/storage/emulated/0/Download/split/"
val fileInfoList = getFileInfoList(apkFilesPath)
installSplitApkFiles(fileInfoList)
}
}
安装本身：
@WorkerThread
private fun installSplitApkFiles(apkFiles: ArrayList<FileInfo>): Boolean {
if (apkFiles.size == 1) {
//single file that we can actually reach, so use normal method
val apkFile = apkFiles[0]
if (apkFiles[0].apkFile != null) {
Log.d("AppLog", "Installing a single APK ${apkFile.name} ${apkFile.fileSize} ")
val installResult = Shell.su("cat \"${apkFile.apkFile!!.absolutePath}\" | pm install -t -S ${apkFile.fileSize}").exec()
Log.d("AppLog", "succeeded installing?${installResult.isSuccess}")
if (installResult.isSuccess)
return true
}
}
var sessionId: Int? = null
Log.d("AppLog", "installing split apk files:$apkFiles")
run {
val sessionIdResult = Shell.su("pm install-create -r -t").exec().out
// Note: might need to use these instead:
// "pm install-create -r --install-location 0 -i '${BuildConfig.APPLICATION_ID}'"
// "pm install-create -r -i '${BuildConfig.APPLICATION_ID}'"
val sessionIdPattern = Pattern.compile("(\\d+)")
val sessionIdMatcher = sessionIdPattern.matcher(sessionIdResult[0])
sessionIdMatcher.find()
sessionId = Integer.parseInt(sessionIdMatcher.group(1)!!)
// Log.d("AppLog", "sessionId:$sessionId")
}
for (apkFile in apkFiles) {
Log.d("AppLog", "installing APK : ${apkFile.name} ${apkFile.fileSize} ")
// pm install-write [-S BYTES] SESSION_ID SPLIT_NAME [PATH]
val command = arrayOf("su", "-c", "pm", "install-write", "-S", "${apkFile.fileSize}", "$sessionId", apkFile.name)
val process: Process = Runtime.getRuntime().exec(command)
val inputPipe = apkFile.getInputStream()
try {
process.outputStream.use { outputStream -> inputPipe.copyTo(outputStream) }
} catch (e: java.lang.Exception) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) process.destroyForcibly() else process.destroy()
throw RuntimeException(e)
}
process.waitFor()
val inputStr = process.inputStream.readBytes().toString(Charset.defaultCharset())
val errStr = process.errorStream.readBytes().toString(Charset.defaultCharset())
val isSucceeded = process.exitValue() == 0
Log.d("AppLog", "isSucceeded?$isSucceeded inputStr:$inputStr errStr:$errStr")
}
// "pm install-commit %d ", sessionId
Log.d("AppLog", "committing...")
val installResult = Shell.su("pm install-commit $sessionId").exec()
Log.d("AppLog", "succeeded installing?${installResult.isSuccess}")
return installResult.isSuccess
}
以获取拆分的apk文件列表为例：
getting a list of split apk files as an example:
fun SimpleDateFormat.tryParse(str: String) = try {
parse(str) != null
} catch (e: Exception) {
false
}
@WorkerThread
private fun getFileInfoList(splitApkPath: String): ArrayList<FileInfo> {
val parentFile = File(splitApkPath)
val result = ArrayList<FileInfo>()
if (parentFile.exists() && parentFile.canRead()) {
val listFiles = parentFile.listFiles() ?: return ArrayList()
for (file in listFiles)
result.add(FileInfo(file.name, file.length(), file))
return result
}
val longLines = Shell.su("ls -l $splitApkPath").exec().out
val pattern = Pattern.compile(" +")
val formatter = SimpleDateFormat("HH:mm", Locale.getDefault())
longLinesLoop@ for (line in longLines) {
// Log.d("AppLog", "line:$line")
val matcher = pattern.matcher(line)
for (i in 0 until 4)
if (!matcher.find())
continue@longLinesLoop
//got to file size
val startSizeStr = matcher.end()
matcher.find()
val endSizeStr = matcher.start()
val fileSizeStr = line.substring(startSizeStr, endSizeStr)
while (true) {
val testTimeStr: String =
line.substring(matcher.end(), line.indexOf(' ', matcher.end()))
if (formatter.tryParse(testTimeStr)) {
//found time, so apk is next
val fileName = line.substring(line.indexOf(' ', matcher.end()) + 1)
if (fileName.endsWith("apk"))
// Log.d("AppLog", "fileSize:$fileSizeStr fileName:$fileName")
result.add(FileInfo(fileName, fileSizeStr.toLong(), File(splitApkPath, fileName)))
break
}
matcher.find()
}
}
// Log.d("AppLog", "result:${result.size}")
return result
}
