我需要弄清楚如何获取或制作Android应用程序的版本号。我需要在UI中显示内部版本号。
我必须使用AndroidManifest.xml吗?

对于API 28(Android 9(Pie)),PackageInfo.versionCode已弃用,因此请使用以下代码:
Context context = getApplicationContext();
PackageManager manager = context.getPackageManager();
try {
PackageInfo info = manager.getPackageInfo(context.getPackageName(), 0);
myversionName = info.versionName;
versionCode = (int) PackageInfoCompat.getLongVersionCode(info);
}
catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
myversionName = "Unknown-01";
}

非常简单:
val manufacturer = Build.MANUFACTURER
val model = Build.MODEL
val version = Build.VERSION.SDK_INT
val versionRelease = Build.VERSION.RELEASE
对构建系统有用:有一个用APK文件生成的文件,名为output.json,其中包含每个生成的APK文件的一系列信息,包括versionName和versionCode。
例如
[
{
"apkInfo": {
"baseName": "x86-release",
"enabled": true,
"filterName": "x86",
"fullName": "86Release",
"outputFile": "x86-release-1.0.apk",
"splits": [
{
"filterType": "ABI",
"value": "x86"
}
],
"type": "FULL_SPLIT",
"versionCode": 42,
"versionName": "1.0"
},
"outputType": {
"type": "APK"
},
"path": "app-x86-release-1.0.apk",
"properties": {}
}
]
版本名称:BuildConfig.version_name版本代码:BuildConfig.version_code
如果您使用的是PhoneGap,请创建自定义PhoneGa插件:
在应用程序包中创建新类:
package com.Demo; //replace with your package name
import org.json.JSONArray;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import com.phonegap.api.Plugin;
import com.phonegap.api.PluginResult;
import com.phonegap.api.PluginResult.Status;
public class PackageManagerPlugin extends Plugin {
public final String ACTION_GET_VERSION_NAME = "GetVersionName";
@Override
public PluginResult execute(String action, JSONArray args, String callbackId) {
PluginResult result = new PluginResult(Status.INVALID_ACTION);
PackageManager packageManager = this.ctx.getPackageManager();
if(action.equals(ACTION_GET_VERSION_NAME)) {
try {
PackageInfo packageInfo = packageManager.getPackageInfo(
this.ctx.getPackageName(), 0);
result = new PluginResult(Status.OK, packageInfo.versionName);
}
catch (NameNotFoundException nnfe) {
result = new PluginResult(Status.ERROR, nnfe.getMessage());
}
}
return result;
}
}
在plugins.xml中,添加以下行:
<plugin name="PackageManagerPlugin" value="com.Demo.PackageManagerPlugin" />
在deviceready事件中,添加以下代码:
var PackageManagerPlugin = function() {
};
PackageManagerPlugin.prototype.getVersionName = function(successCallback, failureCallback) {
return PhoneGap.exec(successCallback, failureCallback, 'PackageManagerPlugin', 'GetVersionName', []);
};
PhoneGap.addConstructor(function() {
PhoneGap.addPlugin('packageManager', new PackageManagerPlugin());
});
然后,您可以通过执行以下操作获取versionName属性:
window.plugins.packageManager.getVersionName(
function(versionName) {
//do something with versionName
},
function(errorMessage) {
//do something with errorMessage
}
);
源自这里和这里。
由于我只需要获取版本代码并检查应用程序是否更新,如果是,我必须启动play商店以获取更新的应用程序。我是这样做的。
public class CheckForUpdate {
public static final String ACTION_APP_VERSION_CHECK = "app-version-check";
public static void launchPlayStoreApp(Context context)
{
// getPackageName() from Context or Activity object
final String appPackageName = context.getPackageName();
try {
context.startActivity(new Intent(Intent.ACTION_VIEW,
Uri.parse("market://details?id=" + appPackageName)));
}
catch (android.content.ActivityNotFoundException anfe) {
context.startActivity(new Intent(Intent.ACTION_VIEW,
Uri.parse("https://play.google.com/store/apps/details?id=" +
appPackageName)));
}
}
public static int getRemoteVersionNumber(Context context)
{
int versionCode = 0;
try {
PackageInfo pInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), 0);
String version = pInfo.versionName;
versionCode = pInfo.versionCode;
}
catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
return versionCode;
}
}
然后,我通过创建一个util类,使用共享首选项保存了版本代码。
public class PreferenceUtils {
// This is for version code
private final String APP_VERSION_CODE = "APP_VERSION_CODE";
private SharedPreferences sharedPreferencesAppVersionCode;
private SharedPreferences.Editor editorAppVersionCode;
private static Context mContext;
public PreferenceUtils(Context context)
{
this.mContext = context;
// This is for the app versioncode
sharedPreferencesAppVersionCode = mContext.getSharedPreferences(APP_VERSION_CODE,MODE_PRIVATE);
editorAppVersionCode = sharedPreferencesAppVersionCode.edit();
}
public void createAppVersionCode(int versionCode) {
editorAppVersionCode.putInt(APP_VERSION_CODE, versionCode);
editorAppVersionCode.apply();
}
public int getAppVersionCode()
{
return sharedPreferencesAppVersionCode.getInt(APP_VERSION_CODE,0); // As the default version code is 0
}
}
