如何在Android内部共享使用instant run创建的拆分APK? 背景
我有一个app(),除其他功能外,它允许共享APK文件 为此,它通过访问packageInfo.applicationInfo.sourceDir(docs链接)的路径到达文件,并只共享文件(如我所用,在需要时使用ContentProvider) 问题 这在大多数情况下都可以正常工作,尤其是从Play Store或独立APK文件安装APK文件时,但当我使用Android Studio本身安装应用程序时,我会在该路径上看到多个APK文件,并且没有一个是可以安装和运行的有效文件,不会出现任何问题 以下是试用以下示例后该文件夹内容的屏幕截图: 我不确定这个问题是什么时候开始的,但至少在我的Nexus5x上,安卓7.1.2版上出现过。也许以前 我发现了什么 这似乎只是因为IDE上启用了instant run,因此它可以帮助更新应用程序,而无需一起重新构建: 禁用后,我可以看到只有一个APK,就像过去一样: 您可以看到正确的APK和拆分的APK之间的文件大小差异 此外,似乎有一个API可以获取所有拆分APK的路径: 问题 共享一个需要拆分为多个APK的APK最简单的方法是什么 真的需要以某种方式合并它们吗 根据以下情况,这似乎是可能的: 零个或多个拆分APK的完整路径,当与 在sourceDir中定义的基本APK,形成一个完整的应用程序 但是正确的方法是什么?有没有快速有效的方法?也许没有真正创建文件 是否有一个API可以从所有拆分的APK中获得合并的APK?或者可能这样的APK已经存在于其他路径中,并且不需要合并如何在Android内部共享使用instant run创建的拆分APK? 背景,android,apk,android-instant-run,Android,Apk,Android Instant Run,我有一个app(),除其他功能外,它允许共享APK文件 为此,它通过访问packageInfo.applicationInfo.sourceDir(docs链接)的路径到达文件,并只共享文件(如我所用,在需要时使用ContentProvider) 问题 这在大多数情况下都可以正常工作,尤其是从Play Store或独立APK文件安装APK文件时,但当我使用Android Studio本身安装应用程序时,我会在该路径上看到多个APK文件,并且没有一个是可以安装和运行的有效文件,不会出现任何问题 以
编辑:刚刚注意到,我尝试过的所有第三方应用程序都应该共享已安装应用程序的APK,但在这种情况下无法共享 对我来说,即时运行是一场噩梦,2-5分钟的构建时间,而且令人抓狂的是,最近的更改常常没有包含在构建中。我强烈建议禁用instant run并将此行添加到gradle.properties:
android.enableBuildCache=true
对于大型项目来说,第一次构建通常需要一些时间(1-2分钟),但在缓存之后,后续构建通常会非常快(将多个拆分的apk合并到单个apk可能有点复杂 下面是一个直接共享拆分的APK并让系统处理合并和安装的建议 这可能不是这个问题的答案,因为它有点长,我在这里作为“答案”发布 框架新API
PackageInstaller
可以处理单片apk
或拆分apk
在开发环境中
- 对于
,使用单片apk
adb安装单片apk
- 对于
,使用splitapk
adb安装多个apk列表
Run
查看以上两种模式,输出取决于您的项目是否具有即时运行
启用或禁用
对于命令adb install multiple
,我们可以看到源代码,它将调用函数install\u multiple\u app
然后执行以下步骤
pm install-create # create a install session
pm install-write # write a list of apk to session
pm install-commit # perform the merge and install
pm
实际上是调用框架apiPackageInstaller
,我们可以看到源代码
这一点也不神秘,我只是在这里复制了一些方法或函数
可以从adb shell
环境调用以下脚本,将所有split-apk
安装到设备,如adb-install-multiple
。如果您的设备是根设备,我认为它可能以编程方式与Runtime.exec一起工作
#!/system/bin/sh
# get the total size in byte
total=0
for apk in *.apk
do
o=( $(ls -l $apk) )
let total=$total+${o[3]}
done
echo "pm install-create total size $total"
create=$(pm install-create -S $total)
sid=$(echo $create |grep -E -o '[0-9]+')
echo "pm install-create session id $sid"
for apk in *.apk
do
_ls_out=( $(ls -l $apk) )
echo "write $apk to $sid"
cat $apk | pm install-write -S ${_ls_out[3]} $sid $apk -
done
pm install-commit $sid
我举了一个例子,拆分的apk包括(我从androidstudioRun
output获得了列表)
使用adb将上述所有APK和脚本推送到公共可写目录,例如/data/local/tmp/slices
,并运行安装脚本,它将安装到您的设备上,就像adb install multiple
一样
下面的代码只是上面脚本的另一个变体,如果你的应用程序有平台签名或者设备是根目录的,我认为它可以。我没有要测试的环境
private static void installMultipleCmd() {
File[] apks = new File("/data/local/tmp/slices/slices").listFiles(new FileFilter() {
@Override
public boolean accept(File pathname) {
return pathname.getAbsolutePath().endsWith(".apk");
}
});
long total = 0;
for (File apk : apks) {
total += apk.length();
}
Log.d(TAG, "installMultipleCmd: total apk size " + total);
long sessionID = 0;
try {
Process pmInstallCreateProcess = Runtime.getRuntime().exec("/system/bin/sh\n");
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(pmInstallCreateProcess.getOutputStream()));

String l;
Pattern sessionIDPattern = Pattern.compile(".*(\\[\\d+\\])");
while ((l = pmCreateReader.readLine()) != null) {
Matcher matcher = sessionIDPattern.matcher(l);
if (matcher.matches()) {
sessionID = Long.parseLong(matcher.group(1));
}
}
Log.d(TAG, "installMultipleCmd: pm install-create sessionID " + sessionID);
} catch (IOException | InterruptedException e) {
e.printStackTrace();
}

private static void checkShouldShowError(int ret, Process process) {
if (process != null && ret != 0) {
BufferedReader reader = null;
try {

String l;
while ((l = reader.readLine()) != null) {
Log.d(TAG, "checkShouldShowError: " + l);

e.printStackTrace();
} finally {
if (reader != null) {

}
同时,简单的方法是,你可以试试框架api。就像上面的示例代码一样,如果设备是根目录或者你的应用程序有平台签名,它可能会工作,但是我没有一个可行的环境来测试它

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
PackageInstaller packageInstaller = context.getPackageManager().getPackageInstaller();
PackageInstaller.SessionParams sessionParams = new PackageInstaller.SessionParams(PackageInstaller.SessionParams.MODE_FULL_INSTALL);
try {
final int sessionId = packageInstaller.createSession(sessionParams);
Log.d(TAG, "installMultiple: sessionId " + sessionId);
PackageInstaller.Session session = packageInstaller.openSession(sessionId);
File[] apks = new File("/data/local/tmp/slices/slices").listFiles(new FileFilter() {
@Override
public boolean accept(File pathname) {
return pathname.getAbsolutePath().endsWith(".apk");
}
});
for (File apk : apks) {
InputStream inputStream = new FileInputStream(apk);
OutputStream outputStream = session.openWrite(apk.getName(), 0, apk.length());
byte[] buffer = new byte[65536];
int count;
while ((count = inputStream.read(buffer)) != -1) {
outputStream.write(buffer, 0, count);
}
session.fsync(outputStream);
outputStream.close();
inputStream.close();
Log.d(TAG, "installMultiple: write file to session " + sessionId + " " + apk.length());
}
try {
IIntentSender target = new IIntentSender.Stub() {
@Override
public int send(int i, Intent intent, String s, IIntentReceiver iIntentReceiver, String s1) throws RemoteException {
int status = intent.getIntExtra(PackageInstaller.EXTRA_STATUS, PackageInstaller.STATUS_FAILURE);
Log.d(TAG, "send: status " + status);
return 0;
}
};
session.commit(IntentSender.class.getConstructor(IIntentSender.class).newInstance(target));
} catch (InstantiationException | IllegalAccessException | NoSuchMethodException | InvocationTargetException e) {
e.printStackTrace();
}
session.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
为了使用隐藏的apiIIntentSender
,我添加了jar库作为提供的依赖项。我是Android Gradle插件的技术负责人@Google,假设我了解您的用例,让我试着回答您的问题
首先,一些用户提到您不应该共享InstantRun启用的构建,他们是正确的。应用程序上的Instant Run构建是针对您要部署到的当前设备/仿真器映像高度定制的。因此,基本上,假设您为运行21的特定设备生成应用程序的IR启用的构建,它将失败得很惨如果您尝试在运行23的设备上使用完全相同的APK,我可以在必要时进行更深入的解释,但只需说,我们在android.jar中找到的API上生成定制的字节码(这当然是特定于版本的)
因此,我认为共享这些APK没有意义,您应该使用禁用IR的构建或发布构建
现在了解一些细节,每个slice APK包含1+dex文件,因此理论上,没有什么可以阻止您解压缩所有这些slice APK,获取所有dex文件并将其填充回base.APK/r
