APK를 설치하지 않고 Android .apk 파일 VersionName 또는 VersionCode 가져 오기

APK를 설치하지 않고 Android .apk 파일 VersionName 또는 VersionCode 가져 오기

---

AndroidManifest.xml 파일을 다운로드 한 후 설치하지 않고 프로그래밍 방식으로 내 APK의 버전 코드 또는 버전 이름을 어떻게 얻을 수 있습니까?

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="xxx.xx.xxx"
    android:versionCode="1"
    android:versionName="1.1" >

예를 들어 장치에 설치 한 후 IIS 서비스에 새 버전이 업로드되어 있는지 확인하고 싶습니다. 새 버전이 아닌 경우 설치하고 싶지 않습니다.

다음은 명령 줄에서 나를 위해 일했습니다.

aapt dump badging myapp.apk

---

참고 : aapt.exe는 build-toolsSDK 의 하위 폴더에 있습니다. 예를 들면 다음과 같습니다.

<sdk_path>/build-tools/23.0.2/aapt.exe

---

final PackageManager pm = getPackageManager();
String apkName = "example.apk";
String fullPath = Environment.getExternalStorageDirectory() + "/" + apkName;        
PackageInfo info = pm.getPackageArchiveInfo(fullPath, 0);
Toast.makeText(this, "VersionCode : " + info.versionCode + ", VersionName : " + info.versionName , Toast.LENGTH_LONG).show();

Android Studio 버전 2.2 이상 을 사용하는 경우 Android Studio 에서 Build → Analyze APK를 사용한 다음 AndroidManifest.xml 파일을 선택하십시오.

이제 이진 XML 데이터에서 APK 파일의 버전을 성공적으로 검색 할 수 있습니다.

이 주제는 내 대답의 열쇠를 얻었습니다 (리보 코드 버전도 추가했습니다). .apk 패키지 내에서 AndroidManifest.xml 파일을 구문 분석하는 방법

또한, 내가 작성한 XML 구문 분석 코드, 특히 버전을 가져 오기 위해 다음과 같습니다.

        if ((new File(conductorApkPath).exists())) {

            JarFile jf = new JarFile(conductorApkPath);
            InputStream is = jf.getInputStream(jf.getEntry("AndroidManifest.xml"));
            byte[] xml = new byte[is.available()];
            int br = is.read(xml);

            //Tree tr = TrunkFactory.newTree();
            String xmlResult = SystemPackageTools.decompressXML(xml);
            //prt("XML\n"+tr.list());

            if (!xmlResult.isEmpty()) {

                String name = parser.getName();
                if (name.equalsIgnoreCase("Manifest")) {

                    String pakVersion = parser.getAttributeValue(null, "versionName");
                            //NOTE: This is specific to my project. Replace with whatever is relevant on your side to fetch your project's version

                    newVersionExists = (isNewer == 1);

For the upgrade scenario specifically an alternative approach might be to have a web service that delivers the current version number and check that instead of downloading the entire apk just to check its version. It would save some bandwidth, be a little more performant (much faster to download than an apk if the whole apk isn't needed most of the time) and much simpler to implement.

In the simplest form you could have a simple text file on your server... http://some-place.com/current-app-version.txt

Inside of that text file have something like

3.1.4

and then download that file and check against the currently installed version.

Building a more advanced solution to that would be to implement a proper web service and have an api call at launch which could return some json, i.e. http://api.some-place.com/versionCheck:

{
    "current_version": "3.1.4"
}

aapt dump badging test.apk | grep "VersionName" | sed -e "s/.*versionName='//" -e "s/' .*//"

This answers the question by returning only the version number as a result. However......

The goal as previously stated should be to find out if the apk on the server is newer than the one installed BEFORE attempting to download or install it. The easiest way to do this is include the version number in the filename of the apk hosted on the server eg myapp_1.01.apk

You will need to establish the name and version number of the apps already installed (if it is installed) in order to make the comparison. You will need a rooted device or a means of installing the aapt binary and busybox if they are not already included in the rom.

This script will get the list of apps from your server and compare with any installed apps. The result is a list flagged for upgrade/installation.

#/system/bin/sh
SERVER_LIST=$(wget -qO- "http://demo.server.com/apk/" | grep 'href' | grep '\.apk' | sed 's/.*href="//' | \
              sed 's/".*//' | grep -v '\/' | sed -E "s/%/\\\\x/g" | sed -e "s/x20/ /g" -e "s/\\\\//g")
LOCAL_LIST=$(for APP in $(pm list packages -f | sed -e 's/package://' -e 's/=.*//' | sort -u); do \
              INFO=$(echo -n $(aapt dump badging $APP | grep -e 'package: name=' -e 'application: label=')) 2>/dev/null; \
              PACKAGE=$(echo $INFO | sed "s/.*package: name='//" | sed "s/'.*$//"); \
              LABEL=$(echo $INFO | sed "s/.*application: label='//" | sed "s/'.*$//"); if [ -z "$LABEL" ]; then LABEL="$PACKAGE"; fi; \
              VERSION=$(echo $INFO | sed -e "s/.*versionName='//" -e "s/' .*//"); \
              NAME=$LABEL"_"$VERSION".apk"; echo "$NAME"; \
              done;)
OFS=$IFS; IFS=$'\t\n'
for REMOTE in $SERVER_LIST; do
    INSTALLED=0
    REMOTE_NAME=$(echo $REMOTE | sed 's/_.*//'); REMOTE_VER=$(echo $REMOTE | sed 's/^[^_]*_//g' | sed 's/[^0-9]*//g')
    for LOCAL in $LOCAL_LIST; do
        LOCAL_NAME=$(echo $LOCAL | sed 's/_.*//'); LOCAL_VER=$(echo $LOCAL | sed 's/^[^_]*_//g' | sed 's/[^0-9]*//g')
        if [ "$REMOTE_NAME" == "$LOCAL_NAME" ]; then INSTALLED=1; fi

As somebody asked how to do it without using aapt. It is also possible to extract apk info with apktool and a bit of scripting. This way is slower and not simple in android but will work on windows/mac or linux as long as you have working apktool setup.

#!/bin/sh
APK=/path/to/your.apk
TMPDIR=/tmp/apktool
rm -f -R $TMPDIR
apktool d -q -f -s --force-manifest -o $TMPDIR $APK
APK=$(basename $APK)
VERSION=$(cat $TMPDIR/apktool.yml | grep "versionName" | sed -e "s/versionName: //")
LABEL=$(cat $TMPDIR/res/values/strings.xml | grep 'string name="title"' | sed -e 's/.*">//' -e 's/<.*//')
rm -f -R $TMPDIR
echo ${LABEL}_$(echo $V).apk

Also consider a drop folder on your server. Upload apks to it and a cron task renames and moves them to your update folder.

#!/bin/sh
# Drop Folder script for renaming APKs
# Read apk file from SRC folder and move it to TGT folder while changing filename to APKLABEL_APKVERSION.apk
# If an existing version of the APK exists in the target folder then script will remove it
# Define METHOD as "aapt" or "apktool" depending upon what is available on server 

# Variables
METHOD="aapt"
SRC="/home/user/public_html/dropfolders/apk"
TGT="/home/user/public_html/apk"
if [ -d "$SRC" ];then mkdir -p $SRC
if [ -d "$TGT" ]then mkdir -p $TGT

# Functions
get_apk_filename () {
    if [ "$1" = "" ]; then return 1; fi
    local A="$1"
    case $METHOD in
        "apktool")
            local D=/tmp/apktool
            rm -f -R $D
            apktool d -q -f -s --force-manifest -o $D $A
            local A=$(basename $A)
            local V=$(cat $D/apktool.yml | grep "versionName" | sed -e "s/versionName: //")
            local T=$(cat $D/res/values/strings.xml | grep 'string name="title"' | sed -e 's/.*">//' -e 's/<.*//')
            rm -f -R $D<commands>
            ;;
        "aapt")
            local A=$(aapt dump badging $A | grep -e "application-label:" -e "VersionName")
            local V=$(echo $A | sed -e "s/.*versionName='//" -e "s/' .*//")
            local T=$(echo $A | sed -e "s/.*application-label:'//" -e "s/'.*//")
            ;;
        esac
    echo ${T}_$(echo $V).apk
}

# Begin script
for APK in $(ls "$SRC"/*.apk); do
    APKNAME=$(get_apk_filename "$APK")
    rm -f $TGT/$(echo APKNAME | sed "s/_.*//")_*.apk
    mv "$APK" "$TGT"/$APKNAME
done

    EditText ET1 = (EditText) findViewById(R.id.editText1);

    PackageInfo pinfo;
    try {
        pinfo = getPackageManager().getPackageInfo(getPackageName(), 0);
        String versionName = pinfo.versionName;
        ET1.setText(versionName);
        //ET2.setText(versionNumber);
    } catch (NameNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

At the moment, this can be done as follows

$ANDROID_HOME/build-tools/28.0.3/aapt dump badging /<path to>/<app name>.apk

In General, it will be:

$ANDROID_HOME/build-tools/<version_of_build_tools>/aapt dump badging /<path to>/<app name>.apk
