you can try this way,
1. check directory is exist or not if not then create directory
File rootDirectory;
PackageManager m = getPackageManager();
String s = getPackageName();
PackageInfo p = null;
try {
p = m.getPackageInfo(s, 0);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
s = p.applicationInfo.dataDir;
rootDirectory = new File(s + "/files");
if (!rootDirectory.exists()) {
rootDirectory.mkdir();
}
String FileName = "Robotto.ttf";
String finalUrl = rootDirectory.getAbsolutePath() + "/" + FileName;
2. Some changes in your code
private class DownloadingTask extends AsyncTask<Void,Void,Void> {
@Override
protected Void doInBackground(Void... voids) {
try {
File rootDirectory = null;
URL url = new URL(fonturl);
HttpURLConnection c = (HttpURLConnection) url.openConnection();
c.setRequestMethod("GET");
c.connect();
FileOutputStream fos = new FileOutputStream(finalUrl);
// Log.i("Download","complete");
// Log.i("File",getFilesDir().getAbsolutePath());
// ( I/File: /data/user/0/com.customfonts/files)//files stores under
// Log.i("FOS",""+fos.toString());
InputStream is = c.getInputStream();
byte[] buffer = new byte[1024];
int len1 = 0;
while ((len1 = is.read(buffer)) != -1) {
fos.write(buffer, 0, len1);
}
fos.close();
is.close();
}
catch (Exception e) {
e.printStackTrace();
outputFile = null;
Log.e("Error", "Download Error Exception " + e.getMessage());
}
return null;
}
}
btnGETDATA.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// String filename="Robottoo.ttf";
getTypeface(finalUrl);
}
});
private Typeface getTypeface(String finalUrl)
{
Typeface font;
try
{
font = Typeface.createFromFile(finalUrl);
// Log.i("FOnt found",""+font);
// (java.lang.RuntimeException: Font not found /data/user/0/com.customfonts/files/Robotoo.ttf)
}
catch (Exception e)
{
e.printStackTrace();
return null;
}
return font;
}
I hope this will help you.
Update 1:
Once check your file name "Robotto.ttf" this is different name.
btnGETDATA.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String filename="Robottoo.ttf";
getTypeface(filename);
}
});
you should use
btnGETDATA.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String filename="Robotto.ttf";
getTypeface(filename);
}
});
Update 2:
check your application having "WRITE_EXTERNAL_STORAGE" permission.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
for more details, you can go threw Write a file in external storage in Android
Update 3: (just copy and paste code this is working)
