xml file is created in the app's corresponding dist folder. The file is located at WorkspaceName>/temp/<AppName>/build/luaandroid/dist. The manifest file provides essential information about your app to the Android operating system, and Google Play store.
Every app project must have an AndroidManifest. xml file (with precisely that name) at the root of the project source set. The manifest file describes essential information about your app to the Android build tools, the Android operating system, and Google Play.
Every project in Android includes a manifest file, which is AndroidManifest. xml, stored in the root directory of its project hierarchy. The manifest file is an important part of our app because it defines the structure and metadata of our application, its components, and its requirements.
I believe that was already answered here.
String versionName = getPackageManager().getPackageInfo(getPackageName(), 0).versionName;
OR
int versionCode = getPackageManager().getPackageInfo(getPackageName(), 0).versionCode;
There is not a way to directly get the version out, but there are two work-arounds that could be done.
The version could be stored in a resource string, and placed into the manifest by:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.somepackage"
android:versionName="@string/version" android:versionCode="20">
One could create a custom view, and place it into the XML. The view would use this to assign the name:
context.getPackageManager().getPackageInfo(context.getPackageName(), 0).versionName;
Either of these solutions would allow for placing the version name in XML. Unfortunately there isn't a nice simple solution, like android.R.string.version
or something like that.
You can use the versionName
in XML resources, such as activity layouts. First create a string resource in the app/build.gradle
with the following snippet in the android
node:
applicationVariants.all { variant ->
variant.resValue "string", "versionName", variant.versionName
}
So the whole build.gradle
file contents may look like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion '24.0.0 rc3'
defaultConfig {
applicationId 'com.example.myapplication'
minSdkVersion 15
targetSdkVersion 23
versionCode 17
versionName '0.2.3'
jackOptions {
enabled true
}
}
applicationVariants.all { variant ->
variant.resValue "string", "versionName", variant.versionName
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.3.0'
compile 'com.android.support:design:23.3.0'
compile 'com.android.support:support-v4:23.3.0'
}
Then you can use @string/versionName
in the XML. Android Studio will mark it red, but the app will compile without issues. For example, this may be used like this in app/src/main/res/xml/preferences.xml
:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory
android:title="About"
android:key="pref_key_about">
<Preference
android:key="pref_about_build"
android:title="Build version"
android:summary="@string/versionName" />
</PreferenceCategory>
</PreferenceScreen>
IF you are using Gradle you can use the build.gradle file to programmatically add value to the xml resources at compile time.
Example Code extracted from: https://medium.com/@manas/manage-your-android-app-s-versioncode-versionname-with-gradle-7f9c5dcf09bf
buildTypes {
debug {
versionNameSuffix ".debug"
resValue "string", "app_version", "${defaultConfig.versionName}${versionNameSuffix}"
}
release {
resValue "string", "app_version", "${defaultConfig.versionName}"
}
}
now use @string/app_version
as needed in XML
It will add .debug
to the version name as describe in the linked article when in debug mode.
I solved this issue by extending the Preference class.
package com.example.android;
import android.content.Context;
import android.preference.Preference;
import android.util.AttributeSet;
public class VersionPreference extends Preference {
public VersionPreference(Context context, AttributeSet attrs) {
super(context, attrs);
String versionName;
final PackageManager packageManager = context.getPackageManager();
if (packageManager != null) {
try {
PackageInfo packageInfo = packageManager.getPackageInfo(context.getPackageName(), 0);
versionName = packageInfo.versionName;
} catch (PackageManager.NameNotFoundException e) {
versionName = null;
}
setSummary(versionName);
}
}
}
Then in my preferences XML:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<com.example.android.VersionPreference android:title="Version" />
</PreferenceScreen>
I use BuildConfig.VERSION_NAME.toString();
. What's the difference between that and getting it from the packageManager?
No XML based solutions have worked for me, sorry.
You can't use it from the XML.
You need to extend the widget you are using in the XML and add the logic to set the text using what's mentioned on Konstantin Burov's answer.
