Android How To Check Version

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 e

Solution 1:

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;
}

Solution 2:

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.
