Android versionCode programmatically

2018-07-02 13:30:33

Is there any way to know dynamically and programmatically the versionCode of an Android application??

I don´t know... maybe something like

 getApplicationContext.getVersionCode();

Thank you very much.

如果您使用gradle（AndroidStudio中的默认设置），您可以：

BuildConfig.VERSION_CODE

You find the following from using this code

 public int getVersionCode() {
    int v = 0;
    try {
        v = getPackageManager().getPackageInfo(getPackageName(), 0).versionCode;
    } catch (NameNotFoundException e) {

    }
    return v;
}

Class Required

import android.content.pm.PackageInfo;
import android.content.pm.PackageManager.NameNotFoundException;

这应该被try ... catch所包围。

PackageInfo pInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
version = pInfo.versionName;
versionCode = pInfo.versionCode;
