Code Snippet SD Cards Network check
Code Snippet SD Cards Network check
In many occassions, we may find a need to check for online condition and download files to our sd card.
PFB the code to check for network availability,
PFB the code to check for network availability,
public boolean isNetworkAvailable() {
ConnectivityManager cm =
(ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
if (netInfo != null && netInfo.isConnectedOrConnecting()) {
return true;
}
return false;
}
PFB the code for SD Card mount check,
private boolean isSDCardMounted() {
String sdCardStatus = android.os.Environment.getExternalStorageState();
return sdCardStatus.equals(android.os.Environment.MEDIA_MOUNTED);
}
PFB the code that returns available space in SD Card,
public int getFreeExtMemory()
{
StatFs statFs = new StatFs(Environment.getExternalStorageDirectory().getAbsolutePath());
int free = ((statFs.getAvailableBlocks() * statFs.getBlockSize()) / 1024);
Log.i("AppInstallChecker", "Available Space : " + free + " KB, Required Space : "+APPSIZE_KB+" KB");
return free;
}
Note : The methods getAvailableBlocks() & getBlockSize() from the above method/snippet is deprecated after api 18, so put a check if needed.
