I have an android app with a custom Application class.
public class MyApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
Utils.isThereUpdatedVersion(this);
}
}
The isThereUpdatedVersion function asks a php page is. There is a new version of my app available and there is a button one goes to another activity with a button to download an install the new version.
I added the android:name attribute to my Manifest
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme"
android:name=".application.MyApplication">
When I run my app through Android Studio, the app is running perfectly. Is there is a new version i can download it and install it. But after the installation, I open the app and I get this error and the app crashes.

Can someone help my with this one ?
Edit
I am calling an URL on my server that redirect me to my .apk and i use this code :
URL url = new URL(arg0[0]);
HttpURLConnection c = (HttpURLConnection) url.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
int lenghtOfFile = c.getContentLength();
String PATH = "/mnt/sdcard/Download/";
File file = new File(PATH);
file.mkdirs();
File outputFile = new File(file, "app.apk");
if(outputFile.exists()){
outputFile.delete();
}
FileOutputStream fos = new FileOutputStream(outputFile);
InputStream is = c.getInputStream();
byte[] buffer = new byte[1024];
int count;
long total = 0;
while ((count = is.read(buffer)) != -1) {
total += count;
fos.write(buffer, 0, count);
publishProgress((int) (total * 100 / lenghtOfFile));
}
fos.close();
is.close();
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(outputFile), "application/vnd.android.package-archive");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // without this flag android returned a intent error!
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
context.startActivity(intent);
