Question

出于某种原因,我的手表可以安装不同的纸面名称。在发射时,我想知道猪肉档案的名称是什么。你们是否知道如何这样做?

Thanks !

Answer 1

final PackageManager pm = getPackageManager();
String apkName = "example.apk";
String fullPath = Environment.getExternalStorageDirectory() + "/" + apkName;        
PackageInfo info = pm.getPackageArchiveInfo(fullPath, 0);

您可以:

info.versionCod

以及

info.versionName

希望你们能帮助你们

Answer 2

The apk or app name can be retrieved using package manager. According to alex s answer here - https://stackoverflow.com/a/30348666/2026280

假设你可以提出猪肉。

public static String getAppLabel(PackageManager pm, String pathToApk) {  
PackageInfo packageInfo = pm.getPackageArchiveInfo(pathToApk, 0);

if (Build.VERSION.SDK_INT >= 8) {
    // those two lines do the magic:
    packageInfo.applicationInfo.sourceDir = pathToApk;
    packageInfo.applicationInfo.publicSourceDir = pathToApk;
}

CharSequence label = pm.getApplicationLabel(packageInfo.applicationInfo);
return label != null ? label.toString() : null;
}

Answer 3

尝试:

ActivityManager actMngr = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
string runningPkg = actMngr.getRunningTasks(1).get(0).topActivity.getPackageName();

PackageManager pm = context.getPackageManager();
ApplicationInfo ai = pm.getApplicationInfo(runningPkg , 0);

添加:

如果你没有拿到纸面名称,那么你可以将其与全数公斤进行比较,并获得相应的用名称。你们可以打上安装的 app子,并用同样的名称:

ArrayList<PackageInfo> res = new ArrayList<PackageInfo>();
PackageManager pm = ctx.getPackageManager();
List<PackageInfo> packs = pm.getInstalledPackages(0);

for(int i=0;i<packs.size();i++) {
    PackageInfo p = packs.get(i);
    String description = (String) p.applicationInfo.loadDescription(pm);
    String  label= p.applicationInfo.loadLabel(pm).toString();
//Continue to extract other info about the app...
}

注:在清单中添加这一许可:

<uses-permission android:name="android.permission.GET_TASKS" />

Answer 4

通过以下网址实现:getPackageArchiveInfo,从一个包裹式的纸面文件:

  PackageInfo package_info = pm.getPackageArchiveInfo(file_path_to_apk, 0);

Answer 5

令我感到担忧的是:

String versionName = "null"; //String apk versionName
                int versionCode = -1; //int versionCode
                String APKFilePath = "/storage/emulated/0/apkname.apk"; //For example
                PackageManager pm = getPackageManager();
                PackageInfo    packageInfo = pm.getPackageArchiveInfo(APKFilePath, 0);
                // the secret are these two lines
                packageInfo.applicationInfo.sourceDir       = APKFilePath;
                packageInfo.applicationInfo.publicSourceDir = APKFilePath;
                Drawable APKicon = packageInfo.applicationInfo.loadIcon(pm); //drawable apk icon
                String   AppName = (String)packageInfo.applicationInfo.loadLabel(pm); // String apk name
                    versionName = packageInfo.versionName; //String version name
                    versionCode = packageInfo.versionCode; //int version code
                    apk_icon.setImageDrawable(APKicon);    //ImageView apk icon
                    Apkpackage.setText(packageInfo.packageName); //TextView apk package name
                    Apkname.setText(AppName); //TextView apk name
                    Apkversion.setText(String.format("Version Name: %s Version Code:%d", versionName, versionCode)); //TextView versionName and versionCode
