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?

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
}
}

这是一个干净的解决方案,基于scottyab(由哈维编辑)的解决方案。它显示了如果方法没有提供上下文,如何首先获取上下文。此外,它使用多行而不是每行调用多个方法。这使您在调试应用程序时更容易。
Context context = getApplicationContext(); // or activity.getApplicationContext()
PackageManager packageManager = context.getPackageManager();
String packageName = context.getPackageName();
String myVersionName = "not available"; // initialize String
try {
myVersionName = packageManager.getPackageInfo(packageName, 0).versionName;
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
现在您在StringmyVersionName中收到了版本名,您可以将其设置为TextView或任何您喜欢的内容。。
// Set the version name to a TextView
TextView tvVersionName = (TextView) findViewById(R.id.tv_versionName);
tvVersionName.setText(myVersionName);
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。
对于不需要应用程序UI的BuildConfig信息,但希望使用此信息设置CI作业配置或其他信息的人,如我:
只要成功构建项目,项目目录下就会有一个自动生成的文件BuildConfig.java。
{WORKSPACE}/build/generated/source/buildConfig/{debug|release}/{PACKAGE}/buildConfig.java
/**
* Automatically generated file. DO NOT MODIFY
*/
package com.XXX.Project;
public final class BuildConfig {
public static final boolean DEBUG = Boolean.parseBoolean("true");
public static final String APPLICATION_ID = "com.XXX.Project";
public static final String BUILD_TYPE = "debug";
public static final String FLAVOR = "";
public static final int VERSION_CODE = 1;
public static final String VERSION_NAME = "1.0.0";
}
通过Python脚本或其他工具分割所需的信息。下面是一个示例:
import subprocess
# Find your BuildConfig.java
_BuildConfig = subprocess.check_output('find {WORKSPACE} -name BuildConfig.java', shell=True).rstrip()
# Get the version name
_Android_version = subprocess.check_output('grep -n "VERSION_NAME" ' + _BuildConfig, shell=True).split('"')[1]
print('Android version: ’ + _Android_version)
Log.e("TAG","VERSION.RELEASE {" + Build.VERSION.RELEASE + "}");
Log.e("TAG","\nVERSION.INCREMENTAL {" + Build.VERSION.INCREMENTAL + "}");
Log.e("TAG","\nVERSION.SDK {" + Build.VERSION.SDK + "}");
Log.e("TAG","\nBOARD {" + Build.BOARD + "}");
Log.e("TAG","\nBRAND {" + Build.BRAND + "}");
Log.e("TAG","\nDEVICE {" + Build.DEVICE + "}");
Log.e("TAG","\nFINGERPRINT {" + Build.FINGERPRINT + "}");
Log.e("TAG","\nHOST {" + Build.HOST + "}");
Log.e("TAG","\nID {" + Build.ID + "}");

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";
}
