I am trying to get my app's version name, as well as the version name saved in a .txt file on my SD card named ver.txt. I can easily get my app's version but how do I read the version stored in my .txt file?
// get local apk version code
PackageManager manager = context.getPackageManager();
PackageInfo info = null;
try {
info = manager.getPackageInfo(context.getPackageName(), 0);
} catch (NameNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// get version code from downloaded .txt file
//
// compareVersions
if (info.versionCode >= 1) {
Toast.makeText(context, "up to date!", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(context, "updates are available", Toast.LENGTH_LONG).show();
}
This is not the complete solution, but you get the idea.
int updateVersionCode = info.versionCode;
try {
File sdcard = Environment.getExternalStorageDirectory();
File file = new File(sdcard, "version.txt");
BufferedReader br = new BufferedReader(new FileReader(file));
String line = null;
if((line = br.readLine()) != null){
updateVersionCode = Integer.parseInt(line);
}
br.close();
}catch (Exception e) {
//Handle errors!
e.printStackTrace();
}
if (info.versionCode < updateVersionCode) {
//The local version is minor, so updates are avaliable...
