Android How to check Version

Question

I did my application in 2.2 environment, when i install my apk in older version i am getting parser error. is there anything possibility to display our own message instead parser error message. As per my opinion it is not.

Where and when do you get this parser error? – thoredge May 07 '11 at 06:57 — thoredge, May 07 '11 at 06:57
At the time when installing the file. – RAAAAM May 07 '11 at 06:59 — RAAAAM, May 07 '11 at 06:59

Do something like this

private int GetVersion()
{
    int version = 0;
    IPackageManager pm = ActivityThread.getPackageManager();
    try
    {
        //returns a ref to my application according to its application name
        ApplicationInfo applicationInfo = pm.getApplicationInfo("com.android.phonetests", 0);

        if (applicationInfo != null) 
        {           
            version = applicationInfo.targetSdkVersion; 

            //2 is 5
            //2.01 6 (Donut - 2.01)
            //2.2  7 (Eclair - 2.2) currently it is Eclair_MR1 (Major Release)                  
            switch (version) 
            {                           
                case Build.VERSION_CODES.ECLAIR_MR1:
                Log.i(LOG_TAG,"[DBG] version: ECLAIR");//2.2  7 (Eclair - 2.2) currently it is Eclair_MR1 (Major Release)
                break;
                case Build.VERSION_CODES.DONUT:
                Log.i(LOG_TAG,"[DBG] version: DONUT");//2.01 6 (Donut - 2.01)
                break;
            }
        }
    } 
    catch (android.os.RemoteException e){}      
    return version;
}

Actually, Eclair is 2.1 (API level 7) and Froyo is 2.2 (API level 8) — Aleadam, May 07 '11 at 05:20
Thanks for immediate replies. I have a doubt, can you explain about what you written in switch case. what Log should do,is that displaying error message or something other than this..?? — RAAAAM, May 07 '11 at 05:23

As I understand it you build for version 2.2 and then you deploy it on an earlier version. Why don't you build it for that earlier version?

I don't think you can get another error than that parse error.

Your idea is good, but what i am asking is in case if i install my apk in older version instead of 2.2, before installing the file i want to display the message like "sorry you need 2.2". is this possible to do in application perspective..?? – RAAAAM May 07 '11 at 07:50
